15.5 Land Possessor Liability & Premises Duties

Key Takeaways

  • At traditional common law, the duty owed by a land possessor depends strictly on the entrant's legal classification: undiscovered trespasser, anticipated trespasser, trespassing child, licensee, or invitee.
  • Possessors owe undiscovered trespassers zero duty except to refrain from intentional, willful, or wanton injury; lethal mechanical traps and spring guns (Katko v. Briney) are barred as deadly force is never privileged to protect unoccupied property.
  • Under the Attractive Nuisance doctrine (Restatement § 339), possessors owe trespassing children a duty of reasonable care regarding dangerous artificial conditions where child trespass is foreseeable, the condition poses an unreasonable risk of death/SBI, youth prevents realization of risk, and the burden of eliminating the hazard is slight.
  • Possessors owe licensees (social guests) only a duty to warn of known, concealed dangerous conditions with no duty to inspect; possessors owe invitees (business patrons and public visitors) an affirmative duty of reasonable care including a mandatory duty to inspect and make safe.
  • In California, Rowland v. Christian abolished the tripartite entrant categories in favor of a single unitary duty of reasonable care under all circumstances (Cal. Civ. Code § 1714), although traditional common law remains the primary focus of multistate examination questions.

Land Possessor Liability & Premises Duties

Exam Snapshot: Premises liability—the law governing the duties owed by possessors of real property to entrants who suffer injury on the land—is among the most predictable and heavily tested topics on the California FYLSE. Under traditional common law, the possessor's duty is strictly determined by the entrant's legal status: undiscovered trespasser, anticipated trespasser, child trespasser (attractive nuisance), licensee, or invitee. Examinees must be able to classify any visitor instantaneously, state the exact standard of care owed to that class, recognize when an invitee is demoted for exceeding the scope of invitation, and contrast the common-law framework with California's landmark unitary standard under Rowland v. Christian.


1. Landowner Liability: The Traditional Tripartite Classifications

At traditional common law (heavily tested on the FYLSE and MBE), the duty owed by a possessor of land to an entrant depends strictly upon the legal status of the entrant at the time of injury.

Entrant Classifications & Landowner Duties
├── Undiscovered Trespasser ──▶ ZERO DUTY (No willful/wanton harm; no lethal spring guns)
├── Anticipated / Known Trespasser ──▶ Duty to warn of KNOWN, CONCEALED, HIGHLY DANGEROUS ARTIFICIAL conditions
├── Child Trespasser (Attractive Nuisance) ──▶ Duty of reasonable care regarding foreseeable artificial hazards
├── Licensee (Social Guest, Volunteer) ──▶ Duty to warn of KNOWN, CONCEALED dangerous conditions (NO duty to inspect)
└── Invitee (Business Patron, Public) ──▶ AFFIRMATIVE DUTY TO INSPECT, discover, and make safe all dangerous conditions

Category 1: The Undiscovered Trespasser

An undiscovered trespasser enters real property without permission, privilege, or legal authority, and the possessor has no knowledge or reason to know of their presence.

  • Duty Owed: Zero duty of care. The landowner owes no duty to inspect, warn, or maintain the premises safely.
  • Limitation on Willful and Wanton Conduct: The landowner cannot intentionally, willfully, or wantonly injure the trespasser. A landowner cannot employ mechanical traps, hidden pitfall snares, or lethal spring guns to protect uninhabited property against trespassers (Katko v. Briney, Iowa 1971; deadly force is privileged only to defend human life, never mere unoccupied real property).

Category 2: The Anticipated, Discovered, or Constant Trespasser

An entrant who enters without permission, but the possessor either has actual physical knowledge of their presence or has reason to know that trespassers frequently intrude upon a limited area (e.g., a visible, worn footpath cutting across railroad tracks or private acreage).

  • Duty Owed: The possessor owes a duty to warn of or make safe dangerous conditions that satisfy four cumulative criteria:
    1. Artificial Condition (human-made structures, ditches, wires; no duty for natural ponds or cliffs);
    2. Highly Dangerous (involves risk of death or serious bodily injury);
    3. Concealed / Hidden from the entrant; and
    4. Known to the possessor.
  • Mnemonic Check: Known, Concealed, Highly Dangerous Artificial Hazards (no duty to inspect).

Category 3: The Child Trespasser & The Attractive Nuisance Doctrine

Under the Attractive Nuisance Doctrine (Restatement (Second) of Torts § 339), a possessor of land owes a duty of reasonable care to eliminate danger or protect trespassing children from foreseeable hazards.

The Five Essential Elements of Attractive Nuisance

  1. Likelihood of Trespass: The possessor knows or has reason to know that children are likely to trespass upon the location (e.g., near schools, residential playgrounds, unfenced lots);
  2. Unreasonable Risk: The possessor knows or should know that the condition involves an unreasonable risk of death or serious bodily injury to children;
  3. Youth Precludes Realization: The children, because of their youth and immaturity, do not discover the condition or fail to realize the risk involved in intermeddling with it;
  4. Slight Utility and Burden: The utility to the possessor of maintaining the condition and the expense or burden of eliminating the danger are slight when compared to the foreseeable risk to children; and
  5. Failure of Reasonable Care: The possessor fails to exercise reasonable care to eliminate the danger (e.g., failing to lock a gate, cap an abandoned well, or remove a ladder).

The Modern Rule on "Attraction": Under early common law, the child had to be lured onto the land by the specific dangerous object itself. Under the modern Restatement rule, the child need NOT be attracted by the dangerous condition. If a child wanders onto private land to chase a butterfly or retrieve a soccer ball, and while on the land falls into an unguarded, unfenced excavation pit, the attractive nuisance doctrine applies if the five elements are met.

Category 4: The Licensee (Social Guests & Solicitors)

A licensee enters land with the possessor's express or implied permission for their own personal purpose, benefit, or social amusement:

  • Typical Licensees: Social guests (dinner party guests), door-to-door salespersons, traveling canvassers, and off-duty employees returning to retrieve personal items.
  • Duty Owed: The possessor owes a duty to warn of or make safe known, concealed dangerous conditions (both artificial and natural) that create an unreasonable risk of harm.
  • The Golden Rule for Licensees: The possessor has ABSOLUTELY NO DUTY TO INSPECT the premises for unknown defects. The possessor is liable only for conditions of which the possessor has actual subjective knowledge.

Category 5: The Invitee (Business Patrons & Public Invitees)

An invitee enters land in response to an express or implied invitation for a purpose connected with the possessor's commercial business, or enters land held open to the general public:

  • Two Types of Invitees:
    1. Business Invitee: Customers entering a retail shop, grocery store, restaurant, gas station, hotel, or paying amusement venue; independent repair contractors servicing premises.
    2. Public Invitee: Members of the public entering land held open generally to the community (public parks, community libraries, museum exhibits, church congregations).
  • Duty Owed: The possessor owes the highest duty of care: an affirmative duty to exercise reasonable care to keep the premises safe. This duty encompasses a mandatory affirmative duty to inspect the premises to discover concealed dangerous conditions, followed by taking reasonable steps to repair, make safe, or provide prominent warnings.
  • Demotion of Status (Exceeding the Scope of Invitation): An invitee remains an invitee only so long as the entrant remains within the physical spatial, temporal, and functional scope of the invitation. If a customer at a restaurant leaves the dining room and wanders through an unmarked door into a private kitchen or dark employee basement, the customer exceeds the scope of the invitation and is instantly demoted to a licensee or trespasser.

2. California's Modern Unitary Rule: Rowland v. Christian (1968)

In California, the rigid common-law tripartite classifications (trespasser, licensee, invitee) were dramatically discarded by the California Supreme Court in the landmark case of Rowland v. Christian (Cal. 1968):

  • The Unitary Standard: Possessors of land owe a single duty of reasonable care under all circumstances to all entrants entering the land (codified under California Civil Code § 1714).
  • Role of Entrant Status: The entrant's status (trespasser vs. invitee) is no longer dispositive. Instead, status is merely one factor among several—including the foreseeability of harm, the closeness of connection between conduct and injury, moral blame, and the availability of insurance—that the jury evaluates in determining whether the possessor acted reasonably.
  • Exam Approach: On the FYLSE, analyze the prompt under the traditional common-law categories first (which MBE questions strictly test), and note California's unitary standard where California distinctions are requested.

3. Lessors and Tenants: Landlord Liability at Common Law

Under historical common law, a lease of real property was treated as a temporary conveyance of the estate. The overarching principle was caveat lessee ("let the tenant beware"): the landlord surrendered possession and control to the tenant and owed no duty to maintain or repair the premises.

The Six Recognized Exceptions to Landlord Immunity

Over time, common-law courts carved out six specific exceptions where a landlord owes a duty of reasonable care to tenants and their guests:

  1. Common Areas: Areas retained within the landlord's possession and control (such as shared hallways, stairwells, lobbies, elevators, parking lots, and exterior walkways). The landlord owes an affirmative duty of reasonable care to inspect, repair, and keep common areas safe.
  2. Latent Defects Known to Landlord: Dangerous concealed conditions that exist at the commencement of the lease, which are known (or should be known) to the landlord, and which the tenant is unlikely to discover upon reasonable inspection. The landlord owes a duty to warn the tenant of such hidden hazards.
  3. Premises Leased for Public Admission: Where property is leased for an activity involving admission of the general public (e.g., an auditorium, sports stadium, exhibition hall, or bowling alley), and the landlord knows or should know that the public will enter before the tenant repairs existing dangerous conditions, the landlord remains liable to public visitors.
  4. Contractual Covenant to Repair: If the landlord expressly agrees in the lease agreement to maintain or repair the premises, the landlord is liable in tort for physical harm caused by unreasonable failure to perform the repair covenant after receiving notice of the defect.
  5. Negligent Repairs Undertaken Voluntarily: Even if under no legal duty to repair, once a landlord voluntarily undertakes repairs, the landlord must perform them with reasonable care. Creating a false sense of security or leaving the defect in a more dangerous condition creates tort liability.
  6. Modern Implied Warranty of Habitability: Modern residential tenancies imply a non-waivable warranty that the dwelling is fit for basic human habitation, establishing affirmative duties to maintain plumbing, heating, waterproofing, and structural safety.

5. Practical Exam Hypotheticals & FYLSE Traps

Trap Scenario 4: The Social Guest and the Loose Handrail

Hypothetical: Brenda invites her close friend Sarah over to her residential home for an informal weekend dinner party. Brenda has lived in the home for ten years and has never noticed that the decorative wooden balustrade lining the interior staircase is subtly rotting at its base; the wood appears entirely solid upon casual visual inspection. As Sarah ascends the stairs to use the restroom, she rests her weight against the balustrade. The post snaps, and Sarah falls four feet, breaking her wrist. Sarah sues Brenda for negligence.

Analysis: Sarah is a social guest, which places her squarely in the common-law category of a licensee. A homeowner owes a licensee only a duty to warn of or make safe dangerous conditions of which the homeowner has actual knowledge and which are concealed from the guest. The homeowner owes a licensee no duty to inspect the premises to discover unknown defects. Because Brenda had no actual knowledge of the rotting sub-surface wood, Brenda breached no duty of care to Sarah under common-law principles.

Trap Scenario 5: The Demoted Invitee in the Backroom

Hypothetical: Charles visits a high-end electronics store to browse laptop computers. While browsing, Charles sees a closed door with a sign that reads: 'Employees Only — Authorized Personnel Only.' Intrigued by what inventory might be inside, Charles turns the handle, enters the unlit storage room, and trips over an open freight elevator shaft, suffering severe injuries. Charles sues the electronics store in negligence.

Analysis: Charles entered the store as a business invitee. However, Charles exceeded the physical and functional scope of the invitation by entering an unauthorized employee storeroom marked 'Employees Only.' Upon entering the unauthorized area, Charles was instantly demoted to a trespasser. The store owner owed Charles no duty to inspect or maintain the storage room safely for his protection, and Charles cannot recover.

A homeowner hosts a social backyard barbecue for several neighborhood friends and coworkers. Before the guests arrive, the homeowner thoroughly inspects the backyard deck and firmly tightens all bolts, leaving the deck in pristine condition. During the party, one of the social guests asks to use the homeowner's bathroom. The homeowner directs the guest down the hallway to the first door on the right. Intrigued by an antique carved wooden door marked 'Private' at the far end of the hallway, the guest ignores the homeowner's instructions, walks past the bathroom, and opens the private door into an unlit basement storage room. Stepping forward into the pitch-black darkness, the guest falls down an open flight of steep basement stairs, suffering serious injuries. In an action for negligence by the guest against the homeowner, what legal duty did the homeowner owe to the guest regarding the unlit basement stairs?

A commercial property owner purchases an abandoned industrial parcel located across the street from a public elementary school. On the parcel sits an obsolete, open-pit gravel sorter with towering iron climbing ladders, completely visible from the schoolyard. The property owner erects no fence around the parcel and places no locks or barricades on the ladders. During recess, an eight-year-old child climbs through the open boundary, scrambles forty feet up the iron ladder, slips on rusted rungs, and falls, sustaining severe brain injuries. In an action by the child's guardian against the property owner, which of the following statements correctly evaluates the applicability of the Attractive Nuisance doctrine?
