Summary. Premises liability looks simple and is not. Whether an owner owes a duty depends on how the visitor is classified in that state, whether the hazard was open and obvious, and whether the injury was caused by the property or by another person. Whether the owner breached usually turns on a narrow evidentiary question — did it know or should it have known, and how long had the condition existed — decided by inspection records and video that either exist or do not. This article covers the classification systems and the trend away from them, how notice is proved and defeated, the mode of operation rule, negligent security claims and the competing foreseeability tests, allocation among landlords, tenants, and contractors, and the evidence practices that decide these cases before suit is filed.

A customer slips on a clear liquid in a grocery aisle and fractures her hip. The store's defense is that it had no notice of the spill.

Whether that defense works depends entirely on facts that were fixed within minutes of the fall and that nobody was thinking about at the time.

If the store's camera covered the aisle and the video shows the spill occurring four minutes before the fall, the store almost certainly wins on notice — four minutes is not enough time for a reasonable inspection to have found it.

If the video shows the spill occurring forty minutes before the fall, and shows two employees walking past it, the store loses.

If the store overwrote the video after thirty days because nobody preserved it, the store may face a spoliation instruction telling the jury it may infer the video was unfavorable — which is worse than either of the first two outcomes, because it converts a factual dispute into a credibility problem.

And if the store's sweep logs show inspections every 30 minutes, signed and timed, the store has an affirmative case rather than a denial.

Premises cases are won and lost in the first hour after the incident and in the ordinary operating records that either exist or do not. The doctrine matters, but it decides fewer cases than the evidence practices do.

Who is on the property

The traditional common law divided entrants into three categories, with different duties owed to each.

Invitees — persons on the property for a purpose connected to the owner's business (business invitees) or on land held open to the public (public invitees). The duty is the highest: to exercise reasonable care, which includes a duty to inspect for hazards, to discover dangerous conditions the owner should know of, and to remedy or warn. Customers, tenants in common areas, delivery drivers, and contractors' employees are ordinarily invitees.

Licensees — persons on the property with permission but not for the owner's benefit. Social guests are the classic case, and their classification surprises people. The duty is to warn of known dangers not obvious to the licensee, but generally no duty to inspect.

Trespassers — persons without permission. The duty is only to refrain from willful or wanton injury, with two significant exceptions: known or frequent trespassers, to whom a duty to warn of known artificial hazards may be owed, and child trespassers under the attractive nuisance doctrine, Restatement (Second) of Torts § 339, which imposes liability where the owner knows or has reason to know children are likely to trespass, knows of an artificial condition involving unreasonable risk, the children because of their youth do not discover or realize the risk, the utility of maintaining the condition and the burden of eliminating it are slight compared to the risk, and the owner fails to exercise reasonable care.

The modern trend. A substantial number of states have abolished or partially merged the categories. Rowland v. Christian, 69 Cal. 2d 108 (1968), replaced them with a general duty of reasonable care under the circumstances, with the entrant's status as one factor in the foreseeability analysis. The Restatement (Third) of Torts adopts a unitary duty of reasonable care to all entrants except flagrant trespassers. Other states have merged invitees and licensees while retaining a distinct rule for trespassers, and several have enacted statutes restoring or codifying the traditional categories after judicial abolition.

Practical significance. In a category state, classification is a threshold question worth litigating, and it changes whether an inspection duty exists at all. In a unitary duty state, classification is folded into reasonableness and rarely disposes of a case. Know which system the forum uses before evaluating the claim, because it changes both the discovery plan and the settlement value.

The condition of the property

The core theory: the owner is liable for injury caused by a dangerous condition on the premises if it knew or should have known of the condition and failed to remedy or warn.

Notice is the battleground.

Actual notice — the owner knew. Proved by prior complaints, prior incidents at the same location, work orders, employee testimony, and internal emails. Prior incident evidence is powerful and is why incident reports are discoverable and why their contents matter enormously.

Constructive notice — the condition existed long enough that a reasonable inspection would have discovered it. Proved by the nature of the condition (dried, tracked-through, dirty, or footprint-marked substances suggest duration), by inspection intervals and their adequacy, by video, and by the absence of any inspection system at all.

Created by the owner. Where the owner or its employee created the condition, no notice is required — the owner is charged with knowledge of what it did. This is why the question "who put it there" precedes the question "how long was it there."

The mode of operation rule, adopted in a number of states, dispenses with notice where the owner's chosen method of doing business makes hazardous conditions reasonably foreseeable and recurrent — self-service produce displays, self-serve beverage stations, open bulk bins, and grocery floors near misting units. Where the rule applies, the plaintiff need not show how long the substance was present, only that the mode of operation created a foreseeable risk and the owner failed to take reasonable measures. States vary widely on whether they recognize it and how broadly.

The open and obvious doctrine relieves the owner of a duty to warn of conditions that a reasonable person would perceive and appreciate — a large puddle, an obvious step down, a clearly marked construction area. Its status differs sharply by state:

  • In some, it negates duty entirely and is dispositive.
  • In others, it goes to comparative fault and is a jury question.
  • In many, it does not apply where the owner should anticipate the harm despite obviousness — because the entrant is distracted (a store's own displays), because the condition is unavoidable if the entrant is to reach the destination, or because the advantage of encountering it outweighs the risk. Restatement (Second) § 343A.

Natural accumulations of snow and ice are treated specially. Several states follow a natural accumulation rule relieving owners of liability for injuries from natural accumulations, unless the owner's actions created an unnatural accumulation or the owner voluntarily undertook removal and did it negligently. Others impose an ordinary reasonableness standard, sometimes with a storm in progress rule permitting the owner to wait a reasonable time after a storm ends. In leases and service contracts, the allocation of snow removal responsibility becomes the operative document.

Building codes and standards. Violation of an applicable code may be negligence per se in some states and evidence of negligence in others. Industry standards — ASTM slip resistance standards, ANSI stair and handrail dimensions, illumination standards — are the substance of expert testimony in these cases even where they are not independently binding, and the recurring findings involve stair riser height variation, missing or non-compliant handrails, transitions between flooring materials, inadequate lighting, and ramp slope.

Common condition claims worth cataloguing: liquid and debris on floors; floor mats that are curled, missing, or improperly placed; uneven pavement and sidewalk defects, frequently subject to state or municipal height differential rules that treat trivial defects as non-actionable; potholes; parking lot striping and wheel stops; inadequate lighting; defective stairs and handrails; door closures and automatic doors; falling merchandise from overhead storage; escalators and elevators; and swimming pools, subject to statutory fencing and safety requirements in most states.

Negligent security

The second major category of premises claim arises when a third party commits a crime on the property and the victim sues the owner for failing to prevent it.

The general rule is that there is no duty to protect against the criminal acts of third parties. The exception, which swallows a good deal of the rule, arises where the criminal act was foreseeable and the owner had a special relationship with the plaintiff — business to customer, landlord to tenant, hotel to guest, common carrier to passenger, school to student.

Foreseeability is the whole case, and the states use four tests:

The specific harm test — a duty arises only if the owner knew or should have known that the specific harm was about to occur. The narrowest, and now a minority position.

The prior similar incidents test — foreseeability requires evidence of prior similar crimes on or near the premises, with courts weighing their number, proximity in time and location, and similarity. Discovery in these cases is therefore organized around police call histories for the address and surrounding blocks, internal incident reports, and security logs.

The totality of the circumstances test — courts consider prior incidents but also the nature and location of the business, the condition of the property, the surrounding neighborhood's crime rate, and any other relevant facts. Broader, and it permits a claim without prior identical crimes.

The balancing test — weighs the foreseeability and gravity of the harm against the burden of imposing a duty to protect. Posecai v. Wal-Mart Stores, Inc., 752 So. 2d 762 (La. 1999), is the leading articulation: the greater the foreseeability and gravity, the greater the duty, with the existence and frequency of prior crimes the most important factor.

If a duty exists, breach is measured against what reasonable security would have been: lighting, cameras (and whether they were monitored or merely recording), access control, fencing, guards and their training and posts, alarm systems, landscaping and sightlines, and — importantly — whether the owner followed its own security policies, which is the most common breach theory because the policies are discoverable and the deviations are documented.

Causation is heavily litigated and is the most common ground for defense verdicts. The plaintiff must show that reasonable security would have prevented the crime, which requires more than speculation and frequently requires expert testimony about deterrence.

Damages in these cases are typically large — they involve serious violent injury — and the intervening criminal act does not break the causal chain where the crime was the very risk that made the owner's conduct negligent.

A note on undertakings. An owner that provides security assumes a duty to do it non-negligently, even where no duty existed initially. That principle creates a genuine tension: providing a guard, a camera system, or a courtesy escort program can create liability that not providing it would not have. The right response is not to withhold security but to document the scope of what is provided, not overstate it in marketing, and perform it consistently — because the claims that succeed generally involve a security program that existed on paper and failed in operation.

Who is responsible: owners, landlords, tenants, and contractors

Landlord and tenant. The traditional rule is that a landlord who surrenders possession is not liable for conditions on the leased premises, with exceptions:

  • Common areas retained under the landlord's control — hallways, stairwells, lobbies, parking areas, and grounds. This is the largest category of landlord liability.
  • Latent defects known to the landlord and not disclosed.
  • Negligent repairs undertaken by the landlord.
  • Premises leased for public admission, where the landlord knows of a dangerous condition existing at the time of the lease.
  • Statutory duties, including habitability obligations and building code requirements, which many states apply regardless of the lease's allocation.
  • Contractual undertakings in the lease itself — a landlord that agrees to maintain, repair, or provide security is liable for doing it negligently.

The lease is the first document to read in any landlord-tenant premises case. Maintenance obligations, repair rights, inspection rights, indemnity, insurance and additional insured requirements, and the allocation of snow removal and security decide who bears the loss between the parties even where both are liable to the plaintiff.

Independent contractors. The general rule is that a property owner is not vicariously liable for the negligence of an independent contractor. The significant exceptions:

  • Retained control — where the owner retains control over the manner of the work, it may be directly liable for negligent exercise of that control.
  • Non-delegable duties — imposed by statute, by contract, or by the nature of the activity, including in many states the duty to maintain premises in a reasonably safe condition for invitees.
  • Inherently dangerous activities.
  • Negligent selection of an incompetent contractor.

Contractors' employees injured on the premises present a distinct and important pattern. The employee's exclusive remedy against their own employer is workers' compensation, so the claim runs against the property owner as a third party. Owners defend on the ground that they delegated safety to the contractor and retained no control; plaintiffs point to the owner's safety requirements, site rules, inspections, and stop-work authority as evidence of retained control. How an owner's contract and site practices are structured therefore determines its exposure, and the drafting question — how much safety oversight to require without acquiring control — has no clean answer.

Statutory and municipal duties overlay all of this: sidewalk maintenance ordinances that shift responsibility to abutting owners; snow removal ordinances; and, for public entities, the immunity framework and notice requirements described in the companion article on sovereign immunity.

Recreational use statutes exist in every state and immunize landowners who permit the public to use their land for recreation without charge from liability for ordinary negligence, typically with exceptions for willful or malicious failure to warn of known dangerous conditions and for consideration paid. They are broad and frequently dispositive in outdoor injury cases.

Dram shop and social host liability for injuries caused by an intoxicated patron, and liability for dog bites under strict liability or one-bite rules, are adjacent regimes with their own statutes.

Defenses

No duty, based on classification, open and obvious condition, natural accumulation, recreational use immunity, or the absence of foreseeability in a negligent security case. This is the strongest defense because it is decided by the court.

No notice — no actual knowledge, and insufficient time for constructive notice. This defense lives or dies on inspection records and video.

Comparative fault, which is now the majority approach and reduces recovery in proportion to the plaintiff's fault, with modified systems barring recovery above 50 or 51 percent. A handful of states retain contributory negligence as a complete bar.

Assumption of risk, primary (no duty as to inherent risks of an activity) and secondary (folded into comparative fault in most states). Releases and waivers are enforceable in many states for recreational activities, subject to public policy limits, clarity requirements, and — in most states — an inability to release gross negligence or willful misconduct.

Causation — that the condition did not cause the fall, which is frequently established by the plaintiff's own testimony that they do not know what caused it.

The plaintiff's own conduct — distraction, footwear, intoxication, disregard of warnings, use of a phone.

Statute of limitations, and for public entities, the notice of claim requirements that dispose of many claims before any of this is reached.

What owners should actually do

Inspection systems. A written inspection program with defined intervals, assigned responsibility, and contemporaneous documentation is the single most valuable defensive asset in this field. Sweep logs signed and timed. Parking lot and exterior walks on a schedule. Stairwell and lighting checks. Record that inspections occurred even when nothing was found, because the value of the log is proving the interval, not proving the finding.

Hazard response. Immediate cordoning, warning cones, and a defined escalation path. Train employees that the first person to see a hazard owns it until it is remedied or handed off.

Incident response — the protocol that decides the case:

  1. Render aid and call for medical assistance.
  2. Preserve the scene and photograph it before cleanup, including the condition, the surrounding area, the lighting, and the plaintiff's footwear if visible.
  3. Preserve the video immediately — a wide time window before and after, and more cameras rather than fewer. This is the step most often missed, and its consequences are the most severe.
  4. Identify witnesses and obtain contact information.
  5. Complete an incident report that records facts, not conclusions. Reports containing speculation about fault, or admissions, are discoverable and are read aloud at trial.
  6. Do not clean up before documenting, and do not repair the condition before photographing it.
  7. Notify the insurer promptly and route the investigation through counsel where the injury is serious.

Litigation holds. Once an incident occurs and litigation is reasonably anticipated, the duty to preserve attaches. Video systems that overwrite on a 14-, 30-, or 60-day cycle destroy the most important evidence in the case automatically, and courts have been unsympathetic to defendants who allowed it. Spoliation sanctions range from an adverse inference instruction to, in serious cases, default. Under Federal Rule of Civil Procedure 37(e), the harshest sanctions for lost electronically stored information require a finding of intent to deprive, but state courts apply their own standards and several are considerably less demanding.

Contracts. Every lease, service contract, and construction contract should address maintenance responsibility, inspection rights, indemnity, insurance with additional insured status and primary and non-contributory language, and — for security services — the scope of what is provided.

Insurance. Confirm general liability limits appropriate to the exposure, an umbrella or excess layer, and — for businesses serving alcohol — liquor liability, which the general liability policy excludes.

Accessibility. ADA Title III obligations for public accommodations are a separate legal regime, but they overlap operationally: the same ramps, handrails, thresholds, and parking spaces appear in both an accessibility audit and a premises hazard survey. Conduct them together.

Conclusion

Three points determine outcomes more than doctrine does.

Notice is proved with records that must exist before the incident. An inspection program with contemporaneous logs converts a defense from a denial into an affirmative showing, and it is the cheapest insurance available to any business with a floor.

Video is the case, and it disappears on a timer. The single highest-value action after any incident is preserving a generous window of footage from every relevant camera. The single most damaging failure is letting it overwrite.

Security creates duty. An owner that undertakes security, or that operates in a location where crime is foreseeable, is measured against reasonable security and — more often — against its own written policies. The claims that succeed are usually the ones where the program existed and was not followed.

Damages and valuation

Understanding what these cases are worth shapes every decision about investigation, reserves, and settlement timing.

Economic damages — past and future medical expenses, past and future lost earnings and lost earning capacity, household services, and life care costs in catastrophic cases. Future medicals and life care plans are proved through expert testimony and are frequently the largest component in a serious injury.

The medical billing problem. What the plaintiff was billed and what was actually paid diverge enormously, and states differ on which number is admissible. Some admit only amounts paid, some admit billed amounts with the collateral source rule barring evidence of insurance payments, and some admit both. This single evidentiary rule can change a case's value by a factor of three, and it should be identified at intake rather than at trial.

Non-economic damages — pain and suffering, disfigurement, loss of enjoyment of life, and, for a spouse, loss of consortium. A minority of states cap non-economic damages in ordinary negligence cases, and the caps that exist most often apply to medical malpractice rather than premises claims.

Punitive damages are unusual in ordinary slip-and-fall cases and are genuinely available in premises cases involving a known, repeated, uncorrected hazard or a security failure the owner had been warned about repeatedly. The evidence that supports them is almost always the defendant's own documents.

Case value drivers in approximate order of impact: the severity and permanence of the injury; whether liability is clear or contested on notice; the plaintiff's comparative fault percentage; the venue; the existence of prior similar incidents; whether the defendant's records help or hurt; and whether video exists.

The asymmetry worth naming. A defendant with strong inspection records and preserved video can resolve a marginal claim early and cheaply. A defendant with neither will pay materially more for the same underlying facts, because the uncertainty is priced into every evaluation. That difference in outcome is created by operational decisions made months before the incident and by preservation decisions made in the hours after it.

A worked example

A tenant in a mid-rise apartment building is assaulted in the parking garage at 11 p.m. She sues the owner and the property manager for negligent security.

Duty. The state applies a totality of the circumstances test. Discovery produces the police call history for the address over three years — showing two prior assaults, eleven vehicle break-ins, and repeated trespass calls — and the building's own incident log, showing tenant complaints about broken garage door mechanisms and burned-out lighting. Foreseeability is established.

Breach. The building's written security policy required that the garage door be maintained in operating condition, that lighting be inspected monthly, and that a courtesy patrol pass through the garage twice nightly. The maintenance work orders show the door mechanism had been reported broken eleven times in fourteen months and repaired each time as a temporary fix. The lighting inspection log has no entries for five months. The patrol service was cancelled for budget reasons nine months earlier, and no tenant was notified.

The breach case is not built on expert opinion about what security should have been. It is built on the owner's own standards and the owner's own records showing they were not met — which is the pattern in nearly every successful negligent security case.

Causation. The plaintiff's expert testifies that a functioning garage door and adequate lighting would have deterred the assault; the defense expert testifies that a determined assailant would not have been deterred and that the assailant may have been a resident with access. Causation is genuinely contested, and it is where the defense has its best argument.

Comparative fault. The defense argues the plaintiff parked in a distant space and was on her phone. In a modified comparative fault state, this is worth something at the margin and is unlikely to bar recovery.

Allocation. The lease and management agreement allocate security responsibility between the owner and the manager, and the manager's insurance names the owner as an additional insured. That contract, drafted years earlier and never revisited, determines which insurer funds the defense and the settlement.

Outcome. The case resolves before trial, at a figure driven mostly by the injury and by the maintenance records. Had the owner either maintained the security program it wrote down or formally revised the policy when it cancelled the patrol, the breach case would have been substantially weaker. Writing a standard and then failing to meet it is worse than never writing it — a fact that argues for realistic policies rigorously followed, not for having no policies.

Frequently asked questions

Does a "wet floor" sign end the case? No, though it helps considerably. It supports the argument that the condition was open and obvious and that the owner warned, and it is evidence of reasonable care. It does not eliminate a duty to remedy, and it does not help if the sign was placed after the fall — which the video will show.

Are incident reports privileged? Usually not. Reports prepared in the ordinary course of business are discoverable. Reports prepared at the direction of counsel in anticipation of litigation may be work product, but the label is not controlling and courts look at why the document was actually created. The practical rule: assume every incident report will be read to the jury, and write it accordingly — facts, not conclusions about fault.

How long do I have to keep video? As a business matter, whatever the system's retention permits. As a legal matter, once an incident occurs that could reasonably lead to litigation, the duty to preserve attaches immediately, and the retention cycle is not a defense.

Is a signed waiver enforceable? Often, for recreational activities, if it is clear, conspicuous, and specific. Most states will not enforce a release of gross negligence or willful misconduct, several restrict releases signed on behalf of minors, and a few refuse to enforce them at all in certain settings.

Am I liable for a customer injured by another customer? Only if the assault was foreseeable and you failed to take reasonable measures. That is the negligent security analysis, and it turns on prior incidents and on whether you followed your own security procedures.

My tenant caused the hazard — am I still liable? Possibly, if the hazard is in a common area under your control, if you retained repair obligations, or if a statute imposes a non-delegable duty. Your recourse against the tenant is the lease's indemnity and insurance provisions, which is why those clauses deserve attention at signing rather than at claim time.

Investigating the plaintiff's side

Counsel evaluating a claim for an injured person should run a parallel checklist, because the same evidentiary facts control and they degrade just as quickly.

Within days. Send a preservation letter to the property owner, the manager, and any security contractor, identifying by name the categories to be preserved: surveillance video for a stated window from all cameras, inspection and sweep logs, maintenance work orders, incident reports, prior incident reports for the same location, security policies and post orders, employee schedules, and any photographs taken. A specific letter is far more effective than a generic one, and it establishes the spoliation predicate if the material disappears.

Photograph the scene before it changes. Conditions get repaired, mats get replaced, and lighting gets fixed — often promptly, and often for good reasons. Subsequent remedial measures are generally inadmissible to prove negligence, but the condition as it existed is the case, and it is documented only if someone documents it.

Identify the correct defendants. The record owner, the property manager, the tenant in possession, the maintenance contractor, the security contractor, and — for exterior conditions — possibly the municipality, which brings the notice-of-claim deadlines into play immediately.

Request public records. Police call histories for the address, code enforcement records, building permits and inspection records, and prior complaints. In a negligent security case, the call history is the case.

Interview witnesses early. Employees change jobs, and the employee who saw the spill twenty minutes earlier will not remember it in eighteen months.

Establish the mechanism of injury precisely. The most common reason a legitimate claim fails is the plaintiff's own deposition testimony that they do not know what caused the fall. Work through the mechanism carefully with the client while memory is fresh, and be candid about what the evidence supports.

A closing note on venue and timing. These cases resolve at very different values in different counties within the same state, and both sides know it. That reality argues for early, honest evaluation rather than reflexive denial, and for investing in the operational records described above — because a defendant whose logs and video establish what happened is not at the mercy of a venue's general disposition, while a defendant with neither is.
