California Premises Liability
Demand letters for stairs, leaks, and lighting in rental properties

California landlord liability for common area hazards: When you're injured in a California apartment, condo, or rental property due to defective stairs, water leaks, or poor lighting, California law provides strong protections. California landlords have both common-law duties under Civil Code § 1714 and statutory habitability obligations under Civil Code §§ 1941-1942.

This guide covers how California law addresses the most common residential premises hazards: stairway defects, water intrusion and leaks, and inadequate lighting. California cases recognize landlord liability for foreseeable injuries in common areas and, in some contexts, for criminal acts enabled by poor security lighting.

I handle California residential premises liability demand letters personally. This page focuses on California-specific law, building codes, habitability statutes, and how these claims intersect with tenant rights and landlord-tenant dynamics in California.

California landlord duty framework for residential premises

California landlords owe both common-law duties (Civil Code § 1714) and statutory habitability duties (Civil Code §§ 1941-1942) to tenants and their guests. These duties apply to common areas the landlord controls and, in many cases, to the interior of rental units once the landlord has notice of unsafe conditions.

Civil Code § 1714: General duty of reasonable care

Like all California property owners, landlords are subject to Civil Code § 1714's general duty of reasonable care. Under Rowland v. Christian, California does not distinguish between invitees, licensees, and trespassers—all lawful visitors are owed a duty of reasonable care.

  • Foreseeability: Was injury from this hazard reasonably foreseeable to landlord?
  • Landlord control: Does landlord have exclusive control of the area (common areas) or concurrent control after notice (inside units)?
  • Burden vs benefit: Is the burden of inspection and repair reasonable given the nature of the property and rental business?
California advantage: Tenants and guests do not need to prove they were "invitees" or that the property was "open to the public." California law imposes a general duty of reasonable care on all landlords toward all lawful occupants and visitors.
Civil Code §§ 1941-1942: Habitability and repair obligations

California's statutory warranty of habitability requires landlords to maintain rental properties in safe, sanitary, and habitable condition. Landlords must provide:

  • Effective waterproofing and weather protection: No leaks, functioning roof and walls
  • Functional plumbing and gas facilities: Hot and cold water, working toilets, no leaks
  • Heating facilities: Adequate heat to maintain habitable temperature
  • Electrical lighting and wiring: Safe, code-compliant electrical systems and lighting in common areas
  • Clean and sanitary buildings: No mold, pests, or hazardous conditions
  • Safe floors, stairways, and railings: Code-compliant stairs, handrails, and walkways
Habitability vs injury claims: Habitability violations (mold, broken stairs, poor lighting) can support both rent withholding/repair-and-deduct remedies AND personal injury claims. Your demand letter can reference habitability violations as evidence of landlord's breach of duty.
Common areas vs interior units
Area Type Landlord Duty in California
Common areas (stairs, hallways, parking) Landlord has duty to inspect regularly and maintain in safe condition. Liable for hazards landlord knew or should have known about through reasonable inspections.
Interior of rental unit (after notice) Once tenant reports unsafe condition (leak, broken floor, faulty wiring), landlord must repair within reasonable time or warn. Failure to repair after notice = liability.
Pre-existing hazards in unit If landlord knew of hazard before tenant moved in and failed to disclose or repair, landlord may be liable even without tenant's prior complaint.
Landlord duty for criminal acts and inadequate security

California courts recognize that landlords may be liable for injuries from third-party criminal acts if crime was foreseeable and landlord failed to take reasonable security measures. This often arises in lighting and security cases.

Key California cases:

  • Ann M. v. Pacific Plaza Shopping Center (1993): Property owner liable for rape in parking structure with poor lighting and no security where prior crimes made assault foreseeable.
  • Delgado v. Trax Bar & Grill (2005): Bar owner liable for assault in poorly lit alley where prior incidents made violence foreseeable.
Foreseeability standard: Landlord is liable for criminal acts only if prior similar crimes on the property made the assault or theft foreseeable. If no prior crime history, liability for criminal acts is unlikely even with poor lighting or security.
California stairway and handrail liability

Stairway defects are the leading cause of serious injuries in California rental properties. California building codes impose specific requirements for stairs, handrails, and railings, and violations can support negligence per se claims.

California Building Code stairway requirements

California incorporates the International Building Code (IBC) and International Residential Code (IRC) with California-specific amendments. Key stairway requirements:

  • Maximum riser height: 7.75 inches (residential); 7 inches (commercial)
  • Minimum tread depth: 10 inches (residential); 11 inches (commercial)
  • Riser height variation: Maximum 3/8 inch variation between risers in a single flight
  • Handrails required: Stairs with 4+ risers must have handrails on at least one side
  • Handrail height: 34-38 inches above stair nosing
  • Handrail graspability: Must be graspable (circular cross-section 1.25-2 inches diameter, or equivalent)
  • Stair width: Minimum 36 inches clear width
  • Lighting: Stairs must be adequately lit, with switches at top and bottom of each stair flight
Negligence per se: In California, violation of a building code safety provision constitutes negligence per se if the code was designed to protect the class of person injured (residential tenants/guests) from the type of harm that occurred (fall injuries).
Common California stairway defects
📏
Inconsistent riser heights
Risers of varying heights (exceeding 3/8 inch variation) cause missteps. Measure and photograph all risers; cite CBC violation in demand letter.
🔨
Broken or missing handrails
Loose, detached, or absent handrails. Photograph mounting points, document prior complaints, cite CBC handrail requirements.
🪜
Loose or cracked treads
Stairs that shift or break underfoot. Photograph damage, document how long defect existed (rust, weathering, prior patch jobs).
💡
Inadequate stairway lighting
Burned-out bulbs, no lights, insufficient illumination. Photograph dark stairs at night, cite CBC lighting requirements.
🧊
Slippery exterior stairs
Polished concrete, no traction strips, algae/moss, wet or icy without mats/salt. Photograph surface, note lack of slip-resistance.
🏗️
Code violations
Prior city or county building department citations for stairway defects. Obtain inspection reports, cite in demand as proof of notice.
How to use building code violations in your demand

When drafting your California demand letter for stairway injuries, explicitly cite California Building Code violations:

Example code violation argument: "The stairway where I fell violates California Building Code Section R311.7.5.1, which requires maximum riser height variation of 3/8 inch. Measurements show riser heights ranging from 7 inches to 8.5 inches (1.5 inch variation), creating a dangerous and illegal condition. Under California negligence per se doctrine, this code violation establishes landlord's breach of duty."

Attach supporting evidence:

  • Photos of stairs with measurements (use tape measure in photo)
  • Building code citations (quote specific CBC sections)
  • Prior tenant complaints about the same stairs
  • City or county building department inspection reports or citations
  • Work orders showing landlord's prior repair attempts (proves notice)
California leak and water intrusion liability

Water leaks in California rental properties create both immediate slip hazards and long-term health risks (mold, respiratory issues). California habitability statutes and health codes impose affirmative duties on landlords to maintain waterproofing and prevent mold.

California habitability requirements for water intrusion

California Civil Code § 1941.1 requires landlords to provide "effective waterproofing and weather protection of roof and exterior walls, including unbroken windows and doors." This duty includes:

  • Roof leaks: Landlord must repair leaking roofs, flashings, and gutters
  • Plumbing leaks: Landlord must maintain functional plumbing with no leaks in pipes, fixtures, or drains
  • Flooding and drainage: Landlord must ensure adequate drainage to prevent water intrusion
  • Mold prevention: Landlord must address moisture problems that lead to mold growth
California mold disclosure and remediation requirements

California Health and Safety Code § 26147 requires landlords to provide tenants with information about mold and its health effects. Once landlord has notice of mold, they must:

  • Investigate the source of moisture causing mold
  • Repair leaks and eliminate moisture sources
  • Remediate mold according to industry standards (remove, not just paint over)
  • Provide temporary housing if mold makes unit uninhabitable
Toxic mold exposure: If you suffered respiratory injuries, allergic reactions, or worsened asthma from mold exposure, you may have claims for both premises liability (slip/fall from wet floors) AND toxic mold exposure (respiratory/health injuries). These are separate claims with different damages.
Common leak and water damage scenarios
🏚️
Roof leaks causing falls
Water pooling in hallways, stairwells, or entryways from leaking roof. Photograph water, damaged ceiling, prior staining showing chronic leak.
🚰
Plumbing leaks and slippery floors
Leaking pipes in units or common areas creating slippery floors or warped surfaces. Document how long leak existed (rust, water damage, prior complaints).
🧼
Laundry room flooding
Overflowing washing machines, broken drains, or defective appliances causing flooding. Photograph standing water, document lack of drainage or maintenance.
🦠
Mold from chronic leaks
Visible mold growth, musty odors, respiratory symptoms. Photograph mold, obtain mold testing reports, document prior complaints about leaks or mold.
🪟
Window and door leaks
Broken windows, gaps around doors, or failed seals allowing rain intrusion. Photograph damage, document prior requests for weatherstripping or caulking.
🌊
Sewer backups and flooding
Sewer line failures causing flooding and health hazards. Document sewage exposure, obtain plumber reports, cite habitability violations.
Proving notice in California leak cases

California landlords are liable for leak-related injuries if they had notice of the leak and failed to repair. Best evidence of notice:

  • Your written complaints: Emails, texts, or maintenance requests reporting the leak
  • Prior repair attempts: Work orders, invoices, or receipts showing landlord attempted (but failed) to fix leak
  • Visible water damage: Photos showing long-standing staining, warping, mold, or rust indicating chronic leak
  • Other tenants' complaints: Testimony from neighbors reporting the same leak or water damage
  • Code violations: City or county health department citations for water intrusion or mold
Habitability rent withholding: If you're a current tenant and the leak also constitutes a habitability violation (making unit unfit for occupation), you may have separate remedies (rent withholding, repair-and-deduct, rent abatement) in addition to injury damages. Consult a California tenant rights attorney for both claims.
California lighting and security liability

Inadequate lighting in California rental properties creates both trip hazards and increased risk of criminal assaults. California landlords have a duty to maintain adequate lighting in common areas and, in some contexts, to take reasonable security measures when crime is foreseeable.

California Building Code lighting requirements

California Building Code and Electrical Code require adequate lighting in common areas:

  • Stairways: Must have illumination with minimum 1 footcandle at stair treads. Switches required at top and bottom.
  • Hallways and corridors: Minimum lighting to allow safe passage. Burned-out bulbs must be replaced promptly.
  • Parking areas: Adequate lighting to allow safe vehicle and pedestrian movement (varies by local code).
  • Entrances and exits: Must be illuminated for safe ingress and egress.
Code violation = negligence per se: If landlord violates California lighting codes and you're injured in a fall, the code violation establishes breach of duty. Attach photos of dark areas at night and cite specific CBC sections in your demand.
Landlord liability for criminal acts in poorly lit areas

California courts recognize that property owners (including landlords) may be liable for injuries from third-party criminal acts if:

  • Crime was foreseeable: Prior similar crimes on the property or in the immediate area made the assault, robbery, or theft foreseeable.
  • Landlord failed to take reasonable security measures: Inadequate lighting, broken locks, lack of security cameras, or failure to repair security equipment.
  • Causal connection: The inadequate security (e.g., poor lighting) directly contributed to the crime (e.g., made it easier for assailant to hide or ambush victim).
Key California security liability cases
⚖️
Ann M. v. Pacific Plaza
Shopping center liable for rape in poorly lit, unsecured parking structure where prior crimes made assault foreseeable. Poor lighting and lack of security patrols = breach of duty.
⚖️
Delgado v. Trax Bar
Bar owner liable for assault in poorly lit alley where prior violent incidents made injury foreseeable. Failure to improve lighting or provide security = breach.
⚖️
Wiener v. Southcoast Childcare
Property owner not liable for criminal act where no prior similar crimes on property. Foreseeability is key—general crime in city is not enough.
How to prove foreseeability in California security cases

To establish landlord liability for criminal acts, you must show prior similar crimes made your injury foreseeable:

  • Police reports: Obtain police crime reports for the property address or immediate surrounding area (100-200 yard radius) showing prior assaults, robberies, burglaries, or thefts.
  • Tenant complaints: Prior complaints to landlord about suspicious activity, break-ins, assaults, or thefts in common areas.
  • News reports: Media coverage of prior crimes on the property.
  • Security incident logs: If property has security, request incident logs showing prior crimes or safety issues.
High bar for foreseeability: California courts require prior similar crimes on the property or in the immediate vicinity. General crime statistics for the city or neighborhood are insufficient. If no prior incidents, liability for criminal acts is unlikely even with poor lighting.
Lighting-related trip and fall claims

Even without criminal act involvement, poor lighting can support trip-and-fall liability if:

  • You tripped on a hazard (uneven concrete, debris, step) that was not visible due to inadequate lighting
  • Landlord violated California Building Code lighting requirements
  • Landlord had notice of burned-out bulbs or broken lighting fixtures
Example lighting demand argument: "The exterior stairway where I fell is governed by California Building Code Section R303.6, requiring adequate illumination of stairways. All three overhead lights were burned out, leaving the stairway in complete darkness at 9 PM when I fell. Multiple tenants (including me) complained to management about the burned-out lights for three weeks before my fall. Landlord's failure to replace bulbs violated the CBC and constitutes negligence per se."

9
Deadline and next steps
Give 30-day deadline. Note that if no settlement, you will file suit in California Superior Court and may report code violations to local building/health department.
California statute of limitations: Personal injury claims in California must be filed within 2 years of the injury date (Code Civ. Proc. § 335.1). If you're also pursuing habitability remedies (rent withholding, repair-and-deduct), different timelines and procedures apply—consult a California tenant rights attorney.
Retaliation protections: California Civil Code § 1942.5 prohibits landlord retaliation (eviction, rent increase, harassment) against tenants who assert legal rights. If landlord retaliates after your demand, you may have additional claims for retaliation, wrongful eviction, and emotional distress.

Frequently asked questions about California residential premises liability

Yes. In California, violation of a building code safety provision constitutes negligence per se if:

  • The code was designed to protect the class of person you belong to (residential tenants/guests)
  • The code was intended to prevent the type of harm that occurred (fall injuries from defective stairs, poor lighting, etc.)
  • The violation was a proximate cause of your injury

How to use negligence per se in your demand:

  • Identify specific California Building Code sections violated (e.g., CBC Section R311.7.5.1 for stair riser heights)
  • Document the violation with photos and measurements
  • Argue the code violation establishes breach of duty as a matter of law
  • Cite prior California cases applying negligence per se to similar code violations

Negligence per se is powerful because it shifts the burden: landlord must prove the violation was excusable or did not cause your injury.

No. California Civil Code § 1942.5 prohibits retaliatory eviction. If your landlord evicts you, refuses to renew your lease, raises rent, or harasses you within 180 days after you send a demand letter or file a lawsuit, California law presumes this is illegal retaliation.

Protected actions include:

  • Complaining to landlord about habitability violations or unsafe conditions
  • Sending demand letters for injuries caused by landlord's negligence
  • Filing lawsuits for premises liability or habitability violations
  • Reporting code violations to city or county building/health departments

Tenant remedies for retaliation:

  • Damages for emotional distress, moving costs, rent differential
  • Attorney fees and costs
  • Injunction against eviction or lease non-renewal
  • Punitive damages if landlord's conduct was malicious

Document all interactions with landlord after sending your demand. If landlord takes adverse action, contact a California tenant rights attorney immediately.

Possibly. If the leak also constitutes a habitability violation (e.g., chronic leak causing mold, warped floors, or rendering unit unfit for occupation), you may have separate habitability remedies in addition to your premises liability injury claim:

California habitability remedies:

  • Repair and deduct (Civil Code § 1942): Pay for repairs yourself and deduct cost from rent (up to one month's rent)
  • Rent withholding: Deposit rent into escrow until landlord makes repairs
  • Rent abatement: Reduce rent proportionally to reflect diminished value of unit
  • Move out: Terminate lease and move out if unit is uninhabitable

Important: Habitability remedies have strict procedural requirements (written notice to landlord, waiting periods, rent escrow accounts). Improper withholding can result in eviction for nonpayment. Consult a California tenant rights attorney before withholding rent.

Your premises liability claim (injury damages) is separate from habitability remedies (rent abatement). You can pursue both simultaneously.

Possibly, but California requires proof that the assault was foreseeable based on prior similar crimes on the property or in the immediate area. Poor lighting alone is not enough—you must show:

  • Prior similar crimes: Police reports showing prior assaults, robberies, or muggings on the property or within 100-200 yards
  • Landlord's knowledge: Landlord knew or should have known about prior crimes (tenant complaints, police notices, news reports)
  • Inadequate security: Landlord failed to take reasonable measures (improve lighting, install cameras, hire security, repair broken locks)
  • Causal connection: Inadequate security directly contributed to the assault (e.g., assailant hid in dark area due to burned-out lights)

Key California cases: Ann M. v. Pacific Plaza (property owner liable for rape in poorly lit parking structure where prior crimes made assault foreseeable). Wiener v. Southcoast Childcare (no liability where no prior similar crimes on property).

Evidence to gather:

  • Police crime reports for property address showing prior incidents
  • Tenant complaints to landlord about suspicious activity or prior crimes
  • Photos of dark, unsecured areas
  • Landlord's failure to repair lights or security equipment despite complaints

You have the same premises liability rights as tenants. California Civil Code § 1714 imposes a general duty of reasonable care on landlords toward all lawful visitors, not just tenants.

Advantages of guest claims:

  • No landlord-tenant relationship = no lease termination or retaliation concerns
  • You may not have been aware of the hazard (unlike tenants who see it daily), strengthening your "open and obvious" defense
  • Fresh perspective on how dangerous and unexpected the hazard was

Challenges: You may have less access to complaint history and maintenance records. Work with the tenant (your host) to obtain:

  • Copies of prior complaints or maintenance requests about the hazard
  • Work orders or repair invoices showing landlord's notice
  • Lease provisions allocating maintenance duties to landlord
  • Contact information for other tenants who complained

Generally, no—California follows the "American rule" that each party pays their own attorney fees unless a statute or contract provides otherwise.

Exceptions:

  • Retaliation claims: If landlord retaliates against you for asserting your rights, California Civil Code § 1942.5 allows recovery of attorney fees
  • Habitability actions: Some California habitability statutes allow fee-shifting (but this is separate from your injury claim)
  • Code of Civil Procedure § 998 offers: If defendant rejects reasonable settlement offer and you win more at trial, you may recover post-offer costs (but not attorney fees)

Most California premises liability cases are handled on contingency: attorney receives a percentage of recovery (typically 33%-40%), and you pay nothing unless you win.
