    INTRODUCTION
    Anthony R. Pineda and Diane Franco (Parents) sued,
    among others, Star World Plaza (Plaza), the Plaza’s owners
    George Younan and Ratiba Younan, and Wayne Ng,1 the Plaza’s
    property manager, for negligence, premises liability, and
    wrongful death, after the Parents’ son, Anthony V. Pineda
    (Anthony), was killed during an armed robbery while he was
    working as a security guard and receptionist at an unlicensed
    marijuana dispensary in the Plaza. The Landlords moved for
    summary judgment, claiming they owed no duty of care to
    Anthony because the armed robbery was not foreseeable and, in
    any event, the Parents could not prove the lack of additional
    security measures contributed to Anthony’s death. The court
    granted summary judgment in the Landlords’ favor, and the
    Parents appealed.
    Under the circumstances of this case, we conclude the
    Landlords owed Anthony a duty to provide minimally
    burdensome security measures—a reinforced security door and
    commercial grade lock—inside the dispensary. We also conclude
    there is a triable issue of fact concerning whether the Landlords’
    failure to provide these security measures contributed to
    Anthony’s death. We therefore reverse the judgment.
    1We collectively refer to the Plaza, the Younans, and Ng as the
    “Landlords.”
    2
    FACTS AND PROCEDURAL BACKGROUND
    1.    The Property
    George and Ratiba Younan own the Plaza, a commercial
    strip mall in the City of San Bernardino. Ng is the Plaza’s
    property manager. Ng handles all of the property’s day-to-day
    management, including negotiating and executing lease
    agreements with new tenants, collecting rent payments from
    existing tenants, and hiring security services to monitor the
    property.
    In November 2014, the Landlords agreed to lease one of the
    Plaza’s units to Ernesto Atanacio III to operate the “House of
    OG,” a medical marijuana dispensary. According to the lease
    agreement, the unit was to “be used exclusively as a Medical
    Marijuana Dispensary in compliance with state regulations.”
    When the lease agreement was executed, and through the events
    leading to this lawsuit, it was illegal to operate marijuana
    dispensaries in San Bernardino.2
    Atanacio agreed to pay $4,000 per month for the first three
    months of rent, with the amount of rent increasing to $5,000 per
    2 Specifically, San Bernardino Municipal Code Chapter 5.05.010 made
    it “unlawful for any person or entity to establish, own, manage,
    conduct, or operate any medical marijuana dispensary … or to
    participate as an employee, contractor, agent, volunteer, or in any
    other manner or capacity, in any medical marijuana dispensary in the
    City of San Bernardino.” Ordinance No. MC-1349, which enacted
    Chapter 5.05.010 of the San Bernardino Municipal Code, states that
    the City banned medical marijuana facilities because other cities that
    had permitted such businesses experienced significant increases in
    violent crime, including burglaries, robberies of customers leaving
    dispensaries, and takeover robberies of dispensaries.
    3
    month for the remainder of the lease. When he signed the lease
    agreement, Atanacio paid the Landlords $18,000, consisting of a
    $10,000 non-refundable security deposit and the first two months
    of rent. The amount of rent the Landlords charged Atanacio was
    significantly higher per square foot than what they charged other
    tenants in the Plaza.3
    2.    Prior Incidents of Violence at the Plaza
    Before the House of OG opened, the Landlords leased retail
    space in the Plaza to another medical marijuana dispensary.
    Although there were no reported incidents of violence involving
    the other dispensary, there were at least seven reported robberies
    and thefts on the Plaza’s property between 2012 and 2014. And,
    about four months before the House of OG opened, a person was
    killed in a gang-related shooting in the Plaza’s parking lot. A few
    months later (but before leasing property to the House of OG), Ng
    hired a security company to patrol the Plaza’s parking area at
    night.
    3.    The Shooting at the Dispensary
    One evening in February 2015, Anthony was working as an
    armed security guard and receptionist at the House of OG.
    Anthony was the only security guard on duty. He was working in
    3 For example, a nutritional store that occupied the same amount of
    square footage as the unit occupied by the House of OG—1,200 square
    feet—paid only $755 per month in rent. And a market that occupied a
    unit that was 10,000 square feet and a Chinese food restaurant that
    occupied a unit that was 2,100 square feet paid, respectively, $4,744
    per month and $1,381 per month in rent. In other words, most of the
    Plaza’s other tenants paid less than $1 per square foot, while the
    House of OG paid between $3.33 and $4.17 per square foot.
    4
    the store’s product room, which was separated from the front
    lobby by a sliding glass window and a “thin paneled unreinforced”
    door that was connected to an “electronic locking mechanism.”
    Shortly before the House of OG was supposed to close that
    night, two men armed with guns entered the dispensary’s lobby.
    They opened the interior door separating the lobby from the
    product room and shot and killed Anthony as he tried to prevent
    them from accessing the product room. The lock on the interior
    door wasn’t working when Anthony was killed.
    4.    The Lawsuit
    The Parents filed a lawsuit against, among others, Star
    World Plaza, the Younans (in their individual capacities and as
    co-trustees of the Younan Family Trust), and Ng, asserting
    claims for negligence, wrongful death, and premises liability, all
    arising out of Anthony’s death during the February 2015 shooting
    at the House of OG. The Parents claimed the Landlords were
    responsible for Anthony’s death because they leased retail space
    to an illegal marijuana dispensary, they knew the Plaza attracted
    violent criminal conduct, and they failed to provide adequate
    security measures to protect tenants and invitees, like Anthony,
    from such conduct.
    The Landlords4 filed separate summary judgment motions.
    In support of their motions, the Landlords submitted the Parents’
    responses to special interrogatories and requests for admissions.
    Ng and George Younan submitted declarations in which they
    4The Younans and the Plaza jointly filed one motion and Ng filed his
    own motion. Because they filed a joint respondents’ brief and don’t
    present any arguments differentiating their legal positions on appeal,
    we discuss the Landlords’ arguments collectively.
    5
    testified that they were unaware of any violent crime that had
    occurred on the Plaza’s property before Anthony was killed at the
    House of OG.
    The Landlords argued they didn’t owe Anthony a duty to
    protect him from third-party criminal conduct because they were
    unaware of any prior criminal conduct at the Plaza, rendering the
    shooting at the dispensary unforeseeable. As for causation, the
    Landlords claimed the Parents couldn’t present any non-
    speculative evidence to support a finding that additional security
    measures would have prevented the shooting that killed
    Anthony.
    The Parents opposed both motions. They contended the
    February 2015 shooting at the House of OG was foreseeable
    because a marijuana dispensary was an obvious target for
    robberies and several violent crimes on the Plaza’s property had
    been reported in the three years before the dispensary opened.
    The Parents claimed the Landlords could have prevented
    Anthony’s death by refusing to lease premises in the Plaza to an
    illegal marijuana dispensary or, in the alternative, by enacting
    more effective security measures at the dispensary, including: (1)
    hiring a second armed guard to protect the outside of the
    dispensary and the dispensary’s lobby; (2) ensuring the
    dispensary was equipped with a working video surveillance
    system that covered the exterior and interior of the dispensary’s
    unit; (3) installing a steel security door equipped with a
    commercial grade keypad lock with a deadbolt and reinforcer
    separating the product room from the lobby; and (4) installing
    bullet proof glass between the lobby and the receptionist. The
    Parents also argued there were triable issues of fact as to
    whether the Landlords contributed to Anthony’s death by leasing
    6
    retail space to an illegal and inherently dangerous business and
    by failing to provide more effective security measures on the
    House of OG’s premises.
    In support of their oppositions, the Parents submitted,
    among other things, police reports and photographs from the
    investigation of the shooting at the House of OG, excerpts of
    transcripts from the criminal trial of the defendants suspected of
    shooting Anthony, and excerpts of the transcripts from Ng’s and
    George Younan’s depositions.5 In one of the police reports, the
    investigating officer observed that the lock on the unreinforced
    door separating the House of OG’s lobby from the product room
    had malfunctioned and the store’s interior and exterior security
    cameras weren’t recording any footage at the time of the
    shooting. And two of the employees who were working at the
    dispensary at the time of the shooting testified that the suspects
    were able to force open the door between the lobby and the
    product room before they shot Anthony.
    The Parents also submitted declarations from Rudy
    Petersen, a police officer and security specialist, addressing the
    industry standards for security measures at marijuana
    dispensaries. According to Petersen, it would have cost: (1) about
    $55 per hour to hire a second armed guard; (2) about $100 per
    month to operate working video surveillance equipment; (3) about
    $1,000 to install a bullet resistant steel security door with a
    commercial grade keypad lock; and (4) between $50 to $150 per
    square foot for a bullet proof window.6
    5   The Landlords didn’t object to any of this evidence.
    6 The court overruled objections to Peterson’s testimony regarding the
    industry standard for security of marijuana dispensaries and his
    7
    The court granted the Landlords’ summary judgment
    motions. The court found the Landlords didn’t owe Anthony a
    duty to protect him from third-party criminal conduct.
    Specifically, the court found the shooting in this case was not
    sufficiently foreseeable to require the Landlords to provide any of
    the Parents’ proposed security measures because there had been
    no similar incidents of violence involving a marijuana dispensary
    on the Plaza’s property in the past. The court also rejected the
    Parents’ claim that the Landlords’ conduct was negligent per se
    because they knowingly leased retail space to a marijuana
    dispensary in violation of local ordinances outlawing such
    businesses. As for causation, the court found the Parents failed to
    establish a triable issue of fact that the Landlords’ failure to
    provide additional security measures at the House of OG
    contributed to Anthony’s death.
    The court entered judgment in the Landlords’ favor. The
    Parents appeal, challenging both orders granting summary
    judgment.
    DISCUSSION
    1.    Principles of Summary Judgment and Standard of
    Review
    A court may grant summary judgment where no triable
    issues of material fact exist and the moving party is entitled to
    judgment as a matter of law. (Merrill v. Navegar, Inc. (2001) 26
    opinion that such measures were necessary to protect persons who
    were lawfully within the dispensaries. The court, however, sustained
    objections to Peterson’s testimony that the lack of an adequate interior
    security door and additional security guard contributed to Anthony’s
    death.
    
    8 Cal.4th 465
    , 476 (Merrill).) Defendants who move for summary
    judgment must show that one or more elements of the plaintiffs’
    claim cannot be established or that there exists a complete
    defense to the claim. (Code Civ. Proc., § 437c, subd. (p)(2).) If the
    defendants make a sufficient showing, the burden shifts to the
    plaintiffs to present evidence establishing a triable issue of
    material fact. (Ibid.) A triable issue of fact exists if the evidence
    would allow a reasonable trier of fact to find in favor of the party
    opposing summary judgment. (Aguilar v. Atlantic Richfield Co.
    (2001) 
    25 Cal.4th 826
    , 850 (Aguilar).)
    We independently review a trial court’s ruling on a motion
    for summary judgment. (Aguilar, 
    supra,
     25 Cal.4th at p. 860.) We
    liberally construe the evidence in favor of the opposing party and
    resolve all doubts about the evidence in that party’s favor.
    (Wiener v. Southcoast Childcare Centers, Inc. (2004) 
    32 Cal.4th 1138
    , 1142.) We consider all evidence the parties submit in
    connection with the motion, except that which the court properly
    excluded. (Merrill, supra, 26 Cal.4th at p. 476.)
    2.    Evidentiary Rulings
    As a preliminary matter, we address the Parents’
    challenges to some of the court’s evidentiary rulings. As we
    explain, none of these challenges are adequately developed in the
    Parents’ opening brief.7
    7 To the extent the Parents present additional arguments in their reply
    brief challenging the court’s evidentiary rulings, those arguments are
    not properly before us. (REO Broadcasting Consultants v.
    Martin (1999) 
    69 Cal.App.4th 489
    , 500 [appellate courts won’t consider
    issues raised for the first time in a reply brief because it deprives
    opposing counsel of the opportunity to respond].)
    9
    In a footnote in their opening brief, the Parents claim the
    court “erroneously denied” their request for judicial notice of a so-
    called “White Paper,” a document drafted by an association of the
    State’s police chiefs outlining the potential risks marijuana
    dispensaries pose to their surrounding communities and citing
    specific examples of violence targeting marijuana dispensaries
    and people who possess marijuana. The San Bernardino City
    Council relied on the “White Paper” when it enacted Chapter 5.05
    of the San Bernardino Municipal Code.
    The Parents don’t develop this point at all, making only a
    conclusory assertion that the court erred when it denied their
    request for judicial notice. It is well-settled that a ruling of the
    lower court is presumed correct, and it is incumbent on the party
    challenging that ruling to affirmatively demonstrate why it was
    erroneous through, among other things, reasoned legal analysis.
    Because the Parents offer no legal argument to support their
    claim that the court erred in excluding the “White Paper,” they
    have waived that claim on appeal. (Dix v. Live Nation
    Entertainment, Inc. (2020) 
    56 Cal.App.5th 590
    , 616 [“ ‘[i]f a
    party’s briefs do not provide legal argument and citation to
    authority on each point raised, “ ‘the court may treat it as waived,
    and pass it without consideration.’ ” ’ ”].)
    Likewise, the Parents have waived their challenges to the
    court’s rulings excluding portions of two of their experts’
    testimony. “It is [the] appellant’s ‘burden to affirmatively
    challenge the trial court’s evidentiary ruling[s], and demonstrate
    the court’s error.’ [Citation.]” (Salas v. Department of
    Transportation (2011) 
    198 Cal.App.4th 1058
    , 1074 (Salas).) If a
    party contends that an evidentiary objection was improperly
    sustained by the trial court, “the party must identify the specific
    10
    objection, provide legal argument explaining why the trial court’s
    ruling was in error, and support that argument with citation to
    pertinent legal authority.” (City of Crescent City v. Reddy (2017) 
    9 Cal.App.5th 458
    , 463.)
    Here, the Parents point to portions of their experts’
    testimony that they claim the court should have admitted. They
    do not, however, “specif[y] the [underlying] evidentiary
    objections” giving rise to the challenged rulings, identify any of
    the multiple grounds on which those objections were made, or
    attempt to explain why those grounds do not support excluding
    the experts’ testimony. “In arguing only generalities, plaintiffs’
    briefs do not contain ‘argument and citations to authority as to
    why the trial court’s evidentiary rulings were wrong.’ [Citation.]”
    (Salas, supra, 198 Cal.App.4th at p. 1074.) Plaintiffs have
    therefore forfeited their challenges to the court’s rulings
    excluding portions of the expert witnesses’ testimony. (Ibid.) In
    any event, any error in excluding portions of the experts’
    testimony was harmless for the reasons we discuss in the
    causation analysis below.
    3.    Legal Principles Concerning a Landlord’s Duty to
    Protect Against Third-Party Criminal Conduct
    When asserting claims for wrongful death, premises
    liability, and negligence arising out of the defendants’ alleged
    negligent maintenance of their property, the plaintiff must show
    the defendants owed the decedent a legal duty and that the
    defendants’ breach of that duty was a cause of the decedent’s
    death. (Ann M. v. Pacific Plaza Shopping Center (1993) 
    6 Cal.4th 666
    , 678 (Ann M.), disapproved on another ground in Reid v.
    Google, Inc. (2010) 
    50 Cal.4th 512
    , 527, fn. 5 (Reid); see also
    Williams v. Fremont Corners, Inc. (2019) 
    37 Cal.App.5th 654
    , 662
    11
    [same analysis applies to a claim for premises liability based on a
    theory of negligence]; Jacoves v. United Merchandising Corp.
    (1992) 
    9 Cal.App.4th 88
    , 105 [a complaint asserting claim for
    wrongful death based on a theory of negligence must contain
    allegations as to all the elements of negligence].)
    The first issue we must decide is whether the Landlords
    owed Anthony a duty to protect him from the third-party criminal
    conduct that resulted in his death—i.e., the armed robbery at the
    House of OG.8 Whether a duty exists is a question of law to be
    decided by the court. (Brown v. USA Taekwondo (2021) 
    11 Cal.5th 204
    , 213 (Brown).)
    Landlords generally owe a duty to their tenants and
    invitees to maintain their property in a reasonably safe condition,
    including taking “reasonable measures to secure areas under the
    landlord[s’] control against foreseeable criminal acts of third
    parties.” (Castaneda v. Olsher (2007) 
    41 Cal.4th 1205
    , 1213
    (Castaneda); see also Civ. Code, § 1714, subd. (a) [“[e]veryone is
    responsible … for an injury occasioned to another by his or her
    want of ordinary care or skill in the management of his or her
    property … .”].) Landlords also owe a duty to “exercise reasonable
    care to discover that criminal acts are being or are likely to be
    committed on its land … .” (Ann M., 
    supra,
     6 Cal.4th at p. 679.)
    Unless created by statute, an exception to a duty requirement
    should only be applied if it is “ ‘ “clearly supported by public
    8 On appeal, Ng doesn’t dispute that the scope of any duty he may owe
    to the Plaza’s tenants and invitees would be the same as the duty owed
    by the Plaza’s owners. (See Frances T. v. Village Green Owners Assn.
    (1986) 
    42 Cal.3d 490
    , 499–503 [acknowledging that property managers
    owe a duty to protect tenants and invitees against foreseeable criminal
    acts].)
    12
    policy.” ’ [Citation.]” (Kesner v. Superior Court (2016) 
    1 Cal.5th 1132
    , 1143 (Kesner); see also Rowland v. Christian (1968) 
    69 Cal.2d 108
    , 112.)
    Whether a landlord should be excepted from the duty to
    protect their tenants and invitees from criminal conduct of others
    is typically analyzed under a four-step process. (Castaneda,
    
    supra,
     41 Cal.4th at p. 1214; see also Brown, supra, 11 Cal.5th at
    pp. 217–218 [Rowland factors determine whether to recognize an
    exception to the general duty of care, not whether to establish the
    existence of a duty in the first instance].) First, we must
    determine the specific measures the plaintiffs claim the
    defendants should have taken to prevent the underlying injury.
    (Castaneda, at p. 1214.) Second, we must evaluate how
    financially and socially burdensome it would be to impose the
    plaintiffs’ proposed measures. (Ibid.) Third, we must “ ‘identify
    the nature’ ” of the third-party criminal conduct that the
    plaintiffs claim could have been prevented had the defendants
    taken the proposed measures and assess how foreseeable it was
    that the criminal conduct would occur. (Ibid.) Fourth, we compare
    the burden of enacting the proposed security measures against
    the foreseeability of the third-party conduct. (Ibid.)
    Generally, the higher the burden to be imposed on a
    landlord, the higher the degree of foreseeability is required. (Tan
    v. Arnel Management Co. (2009) 
    170 Cal.App.4th 1087
    , 1096
    (Tan).) “ ‘ “ ‘On the other hand, in cases where there are strong
    policy reasons for preventing the harm, or the harm can be
    prevented by simple means, a lesser degree of foreseeability may
    be required.’ [Citation.]” ’ [Citation.]” (Castaneda, 
    supra,
     41
    Cal.4th at pp. 1213–1214.) For instance, our Supreme Court has
    held that a “high degree of foreseeability is required in order to
    13
    find that the scope of a landlord’s duty of care includes the hiring
    of security guards” because the “monetary costs of security
    guards is not insignificant” and “the obligation ... is not well
    defined.” (Ann M., supra, 6 Cal.4th at p. 679.) Likewise, a duty to
    refuse to rent to, or a duty to evict, a potentially dangerous
    tenant requires circumstances that would have made the
    plaintiff’s injury highly foreseeable. (Castaneda, at pp. 1219–
    1221.) But where the proposed security measures are minimally
    burdensome, such as requiring the one-time installation of
    unmanned security barriers, only “regular” foreseeability of the
    risk of harm is necessary. (Tan, at pp. 1100–1101 [installation of
    four security gates to protect apartment complex was minimally
    burdensome and required regular foreseeability of risk of harm];
    see also Delgado v. Trax Bar & Grill (2005) 
    36 Cal.4th 224
    , 243,
    fn. 24 (Delgado) [in cases where harm can be prevented by simple
    means or by imposing “merely minimal burdens,” only regular
    foreseeability is required].)
    3.1. The Landlords owed a duty to ensure the
    premises were equipped with a reinforced
    interior security door and commercial grade
    lock.
    We first address whether the court properly found the
    Landlords owed Anthony no duty to enact specific security
    measures on the premises that they leased to the House of OG.
    The Parents claim the Landlords should have provided the
    following security measures to protect Anthony: (1) a second
    armed security guard stationed near the entrance of the
    dispensary; (2) a working video surveillance system that covered
    the exterior and interior of the dispensary’s unit; (3) a steel
    security door with a commercial grade deadbolt lock to separate
    14
    the dispensary’s product room from the lobby; and (4) a
    bulletproof glass receptionist’s window between the dispensary’s
    lobby and the product room. As we explain, the court erred in
    finding the Landlords didn’t owe a duty to Anthony to install a
    reinforced interior security door with a commercial grade lock on
    the premises that they leased to the House of OG.9
    When evaluating the burden of implementing a plaintiff’s
    proposed security measures, courts may look to “various case-
    specific factors,” including the characteristics of the property in
    question. (Vasquez v. Residential Investments, Inc. (2004) 
    118 Cal.App.4th 269
    , 285 (Vasquez), citing Pamela W. v. Millsom
    (1994) 
    25 Cal.App.4th 950
    , 958 [what may be a large burden for
    the owner of small residential or commercial property may be a
    minimal burden for the owner of a large apartment building or a
    shopping center].) Here, the financial and social cost of installing
    a reinforced interior security door with a functioning commercial
    grade lock to separate the dispensary’s customer lobby from the
    product room would have been minimal.
    Rudy Petersen, the Parents’ expert on security standards
    for marijuana dispensaries, testified that it would have cost the
    Landlords about $1,000 to install a reinforced steel security door
    with a commercial grade lock inside the unit they leased to
    Atanacio to operate the House of OG. That would have been a
    one-time expenditure that didn’t necessitate the hiring of
    additional personnel to monitor or otherwise guard the premises.
    9 We don’t address whether the Landlords owed a duty to provide the
    other proposed security measures because, as we explain below, the
    court properly found the Parents could not prove such conduct or
    omissions on the Landlords’ part contributed to Anthony’s death.
    15
    (See Tan, supra, 170 Cal.App.4th at p. 1096 [requirement that
    landlord and manager of apartment complex install four security
    gates with a one-time cost of about $26,000 and no need to hire
    additional security personnel to secure the property against
    third-party crime was minimally burdensome].)
    And, in light of the amount of rent the Landlords charged
    Atanacio to lease the House of OG’s premises, the cost of
    installing the security door and lock would have been negligible.
    As we explained above, the Landlords charged Atanacio between
    $4,000 and $5,000 per month to rent the 1,200 square-foot unit
    where the House of OG operated. That amount of rent on a
    square-foot basis was much higher than the amount of rent the
    Landlords charged the Plaza’s other tenants at the time. Indeed,
    even after accounting for a one-time $1,000 payment, the
    Landlords still would have made more per month on a square-
    foot basis from the dispensary’s rent than they made from any of
    the other units on the Plaza’s premises. This factor clearly weighs
    in favor of finding the Landlords owed a duty to install a
    reinforced security door and lock inside the House of OG’s
    premises.
    Next, we must evaluate the foreseeability of the robbery
    and shooting at the House of OG and balance that foreseeability
    against the burden of installing a reinforced interior security door
    with a commercial grade lock. (See Castaneda, 
    supra,
     41 Cal.4th
    at p. 1214.) In its summary judgment ruling, the court applied a
    heightened foreseeability standard to evaluate whether the
    Landlords could have anticipated the robbery and shooting inside
    the House of OG for purposes of enacting any of the Parents’
    proposed security measures. For example, the court found the
    Parents’ evidence of the July 2014 shooting in the Plaza’s parking
    16
    lot and the other robberies and assaults on the Plaza’s premises
    in the three years before the Landlords leased a unit to the
    dispensary was not sufficiently similar to put the Landlords on
    notice of the type of crime that caused Anthony’s death.
    Specifically, the court focused on the fact George Younan and Ng
    each testified they had no actual knowledge of those prior
    incidents and that none of the incidents occurred inside the
    House of OG’s premises or involved another marijuana
    dispensary at the Plaza.
    The court’s heightened foreseeability analysis was flawed
    as it applied to the proposed security measures of installing a
    reinforced interior security door and commercial grade keypad
    lock. As we explained above, where the plaintiffs’ proposed
    security measures are minimally burdensome, a “lesser degree of
    foreseeability”—i.e., only “regular” foreseeability—of third-party
    criminal conduct is required. (Delgado, supra, 36 Cal.4th at p.
    243, fn. 24.) Applying that standard here, the armed robbery of
    the House of OG was sufficiently foreseeable to trigger the
    Landlords’ duty to install the security door and lock inside the
    dispensary’s premises.
    The Parents presented evidence that there had been at
    least several reported robberies or assaultive crimes and one fatal
    shooting on the Plaza’s premises before the Landlords leased
    retail space to the House of OG. These crimes, while not involving
    a marijuana dispensary or the same unit where the House of OG
    later operated, were similar to the type of crime that caused
    Anthony’s death—i.e., a robbery and fatal shooting. (See Tan,
    supra, 170 Cal.App.4th at p. 1100 [under a lowered standard of
    foreseeability, existence of prior assaultive crimes on defendant’s
    property, even though they weren’t committed in a similar
    17
    manner, were sufficiently similar to make the assault on the
    plaintiff foreseeable].)
    That George Younan and Ng each testified they were
    unaware of the prior incidents of violence that occurred on the
    Plaza’s premises is not dispositive. Actual knowledge of incidents
    involving the same type of conduct as the underlying crime that
    caused the plaintiff’s injury is not required to meet the lower
    standard of foreseeability applicable to the implementation of
    minimally burdensome security measures. (See Vasquez, supra,
    118 Cal.App.4th at p. 286.) That is, it may be sufficient that the
    owners had reason to know that their lack of adequate security
    measures created a risk of third-party criminal conduct. (Ibid.;
    see also Musgrove v. Ambrose Properties (1978) 
    87 Cal.App.3d 44
    ,
    52 [for purposes of foreseeability, a landowner may have reason
    to know of risk of third party crime based on location or character
    of business].)
    As we noted above, landlords owe a duty to exercise
    reasonable care to discover whether criminal acts are being, or
    are likely to be, committed on their land. (Ann M., supra, 6
    Cal.4th at p. 679.) In light of this duty, the Landlords certainly
    had reason to know of the relatively extensive history of violent
    crimes that occurred at the Plaza in the three years before they
    leased retail space to the House of OG. Indeed, a reasonable
    inference can be drawn that, at the very least, Ng was aware of
    the prior fatal shooting on the Plaza’s premises based on the fact
    that he hired a private security company to patrol the Plaza at
    night only a few months after that shooting occurred and shortly
    before leasing space to the House of OG.
    In addition, based on other evidence, it was reasonable to
    infer the Landlords knew of, and were compensated for, the risk
    18
    of leasing retail space to an unlicensed marijuana dispensary.
    The Landlords received above-market rent that was paid in cash,
    and they received a non-refundable security deposit. They also
    failed to verify the identity of the House of OG’s operators or to
    determine whether they had a business license. (Donchin v.
    Guerrero (1995) 
    34 Cal.App.4th 1832
    , 1839 [landlord’s actual
    knowledge can be inferred from circumstantial evidence].)
    Viewing the evidence in a light most favorable to the
    Parents, as we must when reviewing an order granting summary
    judgment, the prior fatal shooting and numerous robberies and
    other assaultive crimes on the Plaza’s premises rendered an
    armed robbery inside one of the businesses at the Plaza
    sufficiently foreseeable to trigger the Landlords’ duty to enact
    minimally burdensome security measures. (See Tan, supra, 170
    Cal.App.4th at p. 1101.)
    The fact that the Landlords didn’t possess or control the
    dispensary’s premises at the time of the shooting doesn’t relieve
    them of a duty of care. The Parents presented evidence that,
    when the Landlords decided to lease the premises to Atanacio,
    they were aware that he intended to operate a medical marijuana
    dispensary. Indeed, the lease agreement states that the unit the
    Landlords leased to Atanacio shall only be used for such
    purposes. Thus, there is evidence that the Landlords were aware
    of the nature of the business Atanacio intended to operate on the
    Plaza’s premises when they still had possession and control of the
    premises where the shooting occurred. The Landlords, therefore,
    had the opportunity to enter the premises that they decided to
    lease to the House of OG and install adequate security measures
    before transferring control and possession of the property to
    19
    Atanacio.10 (See Salinas v. Martin (2008) 
    166 Cal.App.4th 404
    ,
    414 [landlord will not be excepted from duty of care when he was
    able to implement safety measures to prevent the plaintiff’s
    injury before relinquishing possession and control of the property
    to a tenant].)
    In short, the court erred in finding the Landlords owed
    Anthony no duty of care to ensure the dispensary’s premises were
    equipped with a reinforced interior security door and a
    commercial grade lock.
    3.2. The Landlords did not owe a duty to refuse to
    lease to, or a duty to evict, the dispensary.
    The Parents also contend the Landlords owed a duty to
    refuse to rent to the House of OG because it was illegal to operate
    a marijuana dispensary in San Bernardino at the time of the
    armed robbery and such businesses are inherently dangerous. In
    contrast to a duty to impose minimally burdensome security
    measures, the duty not to rent property to a specific tenant or to
    later evict a potentially dangerous tenant requires a high degree
    of foreseeability. (See Castaneda, 
    supra,
     41 Cal.4th at pp. 1219–
    1220.) Generally, that requires the plaintiff to present evidence
    that the landlords were aware that crimes similar to the one that
    10 Although the court didn’t address the issue of breach, there is a
    triable issue of fact as to whether the Landlords breached their duty to
    Anthony to install a reinforced interior security door with a
    commercial grade lock for a similar reason—i.e., despite having
    knowledge of the type of business Atanacio intended to operate on
    their property when they still had possession and control of it, they
    failed to take reasonable steps to prevent a foreseeable type of harm.
    (Kesner, supra, 1 Cal.5th at p. 1144 [unlike duty, breach is a question
    of fact for the jury to decide].)
    20
    caused the plaintiff’s injury had targeted the business at issue to
    render the plaintiff’s attack foreseeable. (See Sharon P. v.
    Arman, Ltd. (1999) 
    21 Cal.4th 1181
    , 1195 (Sharon P.) [seven
    armed robberies targeting bank that served parking garage
    where plaintiff was later sexually assaulted did not render the
    sexual assault sufficiently foreseeable to impose heightened
    security measures].) That level of foreseeability was not present
    here.
    While the Parents submitted evidence of other violent
    crimes occurring on the Plaza’s premises before the armed
    robbery that led to Anthony’s death, it is undisputed that none of
    those prior incidents involved the House of OG or any of the other
    marijuana dispensaries that the Landlords had leased property
    to in the past. Thus, the prior acts of violence on the Plaza’s
    premises were not sufficiently similar to the armed robbery in
    this case to trigger a duty to refuse to rent to, or to evict, the
    House of OG.
    Nor did the Parents establish that a medical marijuana
    dispensary is such an “inherently dangerous” enterprise that the
    presence of such a business always makes it foreseeable that
    armed robberies are likely to occur. The designation of an
    “ ‘inherently dangerous property’ ” is rare and “reserved for
    properties that ‘regardless of their individual physical
    characteristics and locations’ are by their nature, prone to
    violence.” (Lopez v. Baca (2002) 
    98 Cal.App.4th 1008
    , 1017
    (Lopez).) Although the Parents presented evidence that local
    municipalities, including the City of San Bernardino, had banned
    medical marijuana dispensaries because other municipalities had
    experienced an increase in violent crime that may be attributable
    to the operation of such businesses, the Parents presented no
    21
    evidence that all marijuana dispensaries are dangerous
    enterprises and prone to violent criminal attacks.11 (Ibid.
    [plaintiff failed to present evidence that all bars or nightclubs,
    even those operating in violation of the law, are “by their nature
    prone to violent criminal attacks and are thus inherently
    dangerous”].)
    In short, the Parents didn’t establish that the Landlords
    also owed a duty to refuse to rent to, or a duty to evict, the House
    of OG.12
    11Even if we were to assume that the court should have granted the
    Parents’ request for judicial notice of the “White Paper,” that document
    could only establish that marijuana dispensaries are sometimes
    dangerous. It does not establish as a matter of law that all marijuana
    dispensaries are inherently dangerous.
    12 In their oppositions to the motions for summary judgment and on
    appeal, the Parents contend the court should have presumed the
    Landlords’ duty and breach under a theory of negligence per se
    because the Landlords leased property to a type of business that was
    prohibited from operating in San Bernardino. This argument lacks
    merit. A plaintiff must assert a claim for negligence per se based on a
    violation of a statute or ordinance in the operative complaint or he or
    she must later move to amend the operative complaint to assert such a
    claim. (Lopez, supra, 98 Cal.App.4th at p. 1019.) If the plaintiff fails to
    do so, he or she “is precluded from relying on that theory as a basis for
    seeking denial of summary judgment.” (Ibid.) Here, the Parents never
    asserted a claim for negligence per se in their operative first amended
    complaint, nor did they seek leave to amend that complaint to assert
    such a claim. They therefore cannot claim the court erred in granting
    summary judgment because the elements of duty and breach were
    established under this theory.
    22
    4.    There is a triable issue of fact as to whether the
    Landlords’ conduct contributed to Anthony’s death.
    The Parents also contend the court erred in finding, as a
    matter of law, that the Landlords’ failure to provide more
    effective security measures at the House of OG was not a cause
    Anthony’s death. As we explain, there is a triable issue as to
    whether the lack of a reinforced security door with a functioning
    lock separating the dispensary’s lobby from the product room
    contributed to Anthony’s death. As for the other security
    measures proposed by the Parents, the court properly found there
    was no triable issue as to whether the lack of such measures was
    a contributing factor in Anthony’s death.
    After establishing a defendant breached a legal duty, the
    plaintiff must prove that breach was a cause of the plaintiff’s
    injury. (Saelzer v. Advanced Group 400 (2001) 
    25 Cal.4th 763
    ,
    772 (Saelzer).) To do so, the plaintiff needs to establish that the
    defendant’s negligence was a “substantial factor” in causing the
    injury. (Ibid.; see also Sandoval v. Bank of America (2002) 
    94 Cal.App.4th 1378
    , 1385.) To be a “substantial factor,” the
    defendant’s negligence need only have “contributed in some way
    to the plaintiff’s injury.” (Sandoval, at p. 1384.) In other words,
    the element of causation is satisfied if “ ‘but for’ the defendant’s
    negligence the injury would not have been sustained.” (Ibid.)
    As the California Supreme Court has explained, a plaintiff
    must present “nonspeculative evidence” of a causal link between
    the third-party conduct that injured the plaintiff and the
    landlord’s “failure to provide adequate security measures.”
    (Saelzer, supra, 25 Cal.4th at p. 774.) That means the plaintiff
    must be able “to prove it was ‘more probable than not’ that
    additional security precautions would have prevented the
    23
    attack.” (Id. at p. 776.) Generally, it is not enough to defeat
    summary judgment by “simply criticiz[ing], through the
    speculative testimony of supposed security ‘experts,’ the extent
    and worth of the defendant’s security measures … .” (Id. at p.
    774.) Instead, the plaintiff “must show the injury was actually
    caused by the failure to provide greater security measures.”
    (Ibid.)
    As a preliminary matter, the Landlords met their initial
    burden on summary judgment to negate the element of causation
    by “point[ing] to the absence of evidence to support” the Parents’
    claim that their omissions were a cause of Anthony’s death.
    (Saelzer, supra, 25 Cal.4th at pp. 780–781.) The burden,
    therefore, shifted to the Parents to produce evidence that would
    establish a triable issue as to causation.
    Here, the Parents presented evidence that would support a
    finding that the Landlords’ failure to install an adequate security
    door with a functioning lock between the dispensary’s lobby and
    its product room was a substantial factor in causing Anthony’s
    death. As we discussed above, the Parents submitted a police
    report from the investigation of the shooting at the dispensary.
    The officer who drafted the report noted that the lock on the
    security door between the lobby and the product room wasn’t
    working at the time of the shooting. Specifically, the officer noted
    that even though the doorknob appeared to be in a locked
    position, a person in the lobby could still push the door open to
    access the product room where Anthony was working when he
    was shot. In addition, two of the employees who were working at
    the House of OG at the time of the shooting testified that
    although customers weren’t supposed to be able to access the
    product room from the lobby without being “buzzed in” through a
    24
    remote locking mechanism, the intruders were able to force the
    door open and enter the product room immediately before
    shooting Anthony. This evidence supports an inference that but
    for the Landlords’ failure to install a reinforced security door with
    a commercial grade lock, the intruders wouldn’t have been able to
    access the product room where they shot Anthony.
    Indeed, this case presents a similar situation to the
    hypothetical our Supreme Court posed in Saelzer to illustrate
    when a causal link between a landlord’s failure to take adequate
    steps to secure premises against foreseeable third-party crime
    and a plaintiff’s injuries can be established with sufficient
    certainty to support a claim for negligence. There, the court
    explained that a plaintiff could establish the necessary causal
    link by showing “the assailant took advantage of the defendant’s
    lapse (such as a failure to keep a security gate in repair) in the
    course of committing his attack, and that the omission was a
    substantial factor in causing injury.” (Saelzer, supra, 25 Cal.4th
    at p. 779; see also ibid. [“ ‘When an injury can be prevented by a
    lock or a fence or a chain across a driveway or some other
    physical device, a landowner’s failure to erect an appropriate
    barrier can be the legal cause of an injury inflicted by the
    negligent or criminal act of a third person.’ ”].) The Parents’
    evidence supports a finding that such a scenario existed in this
    case—i.e., that the Landlords’ failure to provide an adequate
    barrier securing the area of the dispensary where Anthony was
    working from the public’s entrance to the store contributed to
    Anthony’s death.
    The Parents failed, however, to create a triable issue as to
    whether the Landlords’ failure to provide the other proposed
    security measures—i.e., an additional security guard, working
    25
    interior and exterior security cameras, and a bulletproof
    receptionist’s window between the dispensary’s lobby and product
    room—were a substantial factor in causing Anthony’s death.
    That is, the Parents didn’t present any “nonspeculative evidence”
    that could establish a causal link between the absence of such
    security measures and the fatal shooting in this case. (See
    Saelzer, supra, 25 Cal.4th at p. 776.)
    Even if we were to assume the court should have admitted
    Petersen’s testimony addressing the issue of causation, that
    testimony was nothing more than speculation as it related to the
    other proposed security measures. That is, while Petersen
    explained how the lack of a reinforced interior security door
    contributed to Anthony’s death,13 he claimed only that the other
    measures were “necessary.” Petersen didn’t point to any evidence
    to support that conclusion, nor did he attempt to explain in any
    detail how those other measures could have prevented Anthony’s
    death. (Saelzer, supra, 25 Cal.4th at pp. 775–776 [“ ‘A mere
    possibility of … causation is not enough; and when the matter
    remains one of pure speculation or conjecture, or the probabilities
    are at best evenly balanced, it becomes the duty of the court to
    direct a verdict for the defendant.’ ”]; see also Sharon P., supra, 21
    Cal.4th at pp. 1195–1196 [it is difficult to predict how an
    increased presence of security guards, the installation of working
    security cameras, or improved lighting would deter a specific
    assault], disapproved on another ground in Reid, 
    supra,
     50
    13The court excluded this testimony as speculative and lacking a
    proper foundation. We need not decide whether that ruling was correct
    because other evidence, which we discussed above, independently
    created a triable issue of fact as to the issue of causation concerning
    the lack of an adequate interior security door and lock.
    26
    Cal.4th at p. 527, fn. 5.) Because the Parents offered no evidence
    independent of Petersen’s testimony that would support a finding
    of a causal link between the shooting that caused Anthony’s
    death and the Landlords’ failure to provide an additional security
    guard, a bulletproof receptionist’s window, or working interior
    and exterior security cameras, the court properly found there was
    no triable issue on causation as to those measures.
    DISPOSITION
    The judgment is reversed and the matter is remanded for
    further proceedings consistent with the views expressed in this
    opinion. The Parents shall recover their costs on appeal.
