If you fell down stairs in California, the property owner may be liable if the stairway was unsafe and the owner knew or should have known about it. Common failures include a missing or wrong-height handrail, uneven risers, poor lighting, and worn treads. You generally have two years to file, and only six months if a government entity owns the property.
B&D Injury Law Group handles premises liability claims across California. This article explains what makes a stairway legally defective, the building code numbers that these cases turn on, the different rules for landlords and public property, and what to do in the days after a fall.
The Legal Duty Behind a Stairway Claim
California premises liability is a species of ordinary negligence rather than a separate tort. Civil Code section 1714(a) states that everyone 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.
Before 1968, the outcome often turned on whether the injured person was an invitee, a licensee or a trespasser. Rowland v. Christian (1968) 69 Cal.2d 108 replaced those categories with a single reasonable-care standard, holding that the proper test is whether the possessor of land acted as a reasonable person in view of the probability of injury to others.
It is worth being accurate about what Rowland did. It held that a visitor’s status is “not determinative” and may still “have some bearing” on liability. Status was demoted, not erased, and it still informs what harm was foreseeable. The court set out seven factors that continue to shape duty analysis: the foreseeability of harm, the degree of certainty of injury, the closeness of the connection between conduct and injury, the moral blame attached to the conduct, the policy of preventing future harm, the burden on the defendant and consequences to the community, and the availability and cost of insurance.
The Building Code Numbers These Cases Turn On
Most stairway cases are won or lost on measurements. The current standards come from the 2025 California Building Standards Code, Title 24, which took effect January 1, 2026. Commercial buildings and most multifamily properties fall under Part 2, the California Building Code. Detached one- and two-family homes and townhouses fall under Part 2.5, the California Residential Code.
| Requirement | Commercial (CBC) | Homes (CRC) |
|---|---|---|
| Riser height | 4 in. minimum, 7 in. maximum (§ 1011.5.2) | 7¾ in. maximum (R311.7.5.1) |
| Tread depth | 11 in. minimum (§ 1011.5.2) | 10 in. minimum (R311.7.5.2) |
| Variation within one flight | Greatest may not exceed smallest by more than 3/8 in. (§ 1011.5.4) | Same 3/8 in. tolerance (R311.7.5.1, R311.7.5.2) |
| Handrail height | 34 to 38 in., uniform (§ 1014.2) | 34 to 38 in. (R311.7.8) |
| Handrails required | Both sides of a flight (§ 1011.11), with limited exceptions | At least one side, flights of 4 or more risers (R311.7.8) |
The 3/8 inch uniformity tolerance deserves emphasis because it explains a category of fall that people blame on themselves. Walking a staircase is largely automatic, and the body calibrates to the first few steps. A single riser materially taller or shorter than its neighbors defeats that calibration, which is precisely why the code is written as a tolerance across the flight rather than a simple maximum.
In public accommodations, Chapter 11B adds accessibility requirements, including handrails on both sides continuous for the full length of a flight, a graspable cross-section, and extensions past the top and bottom nosings.
If the fall happened at work, a different standard applies. Cal/OSHA’s regulation at title 8, section 3231 requires risers between 4 and 7½ inches and a run of at least 10 inches, with the same 3/8 inch uniformity tolerance across a flight.
Two Cautions About Code Violations
A code violation is powerful evidence, but two qualifications keep it from being the whole case.
First, a violation creates a rebuttable presumption of negligence under Evidence Code section 669, not automatic liability. The presumption can be rebutted, and the injured person still must prove causation and damages.
Second, the applicable code edition is generally the one in force when the stairway was built or permitted, not the current one. A 1962 staircase is not defective merely because it fails a 2025 standard. What often matters more is whether the stairway was altered without a permit, whether it was maintained in the condition the original code required, and whether a later hazard such as worn nosings or a loosened rail developed and went unaddressed.
If You Fell at a Rental Property
Landlord cases run on their own track. Civil Code section 1941 requires a lessor of a building intended for human occupation to put it in a condition fit for occupation and repair subsequent dilapidations. Section 1941.1 lists the characteristics of a tenantable dwelling, and subdivision (a)(8) names floors, stairways, and railings maintained in good repair.
The practical rule comes from the standard jury instruction on a landlord’s duty, CACI 1006, and it splits along control. For areas under the landlord’s control, such as exterior stairs, shared stairwells and walkways, the landlord must take reasonable precautions against unsafe conditions it knows about or reasonably should have known about. For areas under the tenant’s control, such as an interior staircase inside a unit, the landlord is responsible only where it has actual knowledge of the condition and the right and ability to correct it.
That distinction usually decides the case, which is why written complaints matter enormously. A maintenance request describing a loose railing converts an argument about what the landlord should have known into a record of what it actually knew.
Control rather than title is what triggers the duty. Alcaraz v. Vece (1997) 14 Cal.4th 1149 held that duties connected with the condition of land are owed by the person in possession, not invariably by the titleholder. A property manager or a commercial tenant maintaining a stairway can be a proper defendant.
If You Fell on Public Property
Falls on stairs at a courthouse, transit station, school, library or public garage are governed by the Government Claims Act, and the deadlines are short enough to end otherwise strong cases.
Government Code section 835 makes a public entity liable for injury caused by a dangerous condition of its property if the plaintiff establishes that the property was in a dangerous condition at the time of injury, that the injury was proximately caused by that condition, and that the condition created a reasonably foreseeable risk of the kind of injury incurred. In addition, the plaintiff must show either that an employee’s negligent act created the condition, or that the entity had actual or constructive notice long enough beforehand to have protected against it.
Two deadlines apply, and missing either is usually fatal. Under section 911.2, a claim for personal injury must be presented to the entity within six months of accrual. Then, under section 945.6, once the entity rejects the claim, suit must be filed within six months of the rejection notice. The ordinary two-year statute does not rescue someone who filed a timely claim and then waited.
Deadlines and Shared Fault
For private property, Code of Civil Procedure section 335.1 gives two years from the date of injury for a personal injury claim.
Expect an argument that you were not watching where you were going. California applies pure comparative negligence under Li v. Yellow Cab Co. (1975) 13 Cal.3d 804, so a share of fault reduces recovery proportionally rather than barring it. Under Civil Code section 1431.2, economic damages remain jointly and severally recoverable while non-economic damages are allocated among defendants by percentage of fault.
What To Do After a Stairway Fall
Photograph the stairway the day it happens, before anything is repaired. Capture the full flight, then individual steps with a tape measure or a common object for scale, the handrail and its height, the lighting, and the surface of the treads. Repairs made after a fall are common, and the evidence of the original condition often exists only in the photographs taken that day.
Report the fall in writing and ask for a copy of the incident report. Get names of anyone who saw it. Keep the shoes you were wearing, unwashed, because footwear becomes an issue in nearly every one of these cases. Seek medical attention the same day, both for your health and because a gap in treatment is the first thing an adjuster will point to.
Can I sue if I fell down stairs in a store or apartment building?
Possibly. You would need to show the stairway was in an unsafe condition and that the owner or the party in control knew or reasonably should have known about it and failed to fix it. Code violations such as uneven risers or a missing handrail are strong evidence, though they create a rebuttable presumption rather than automatic liability.
What makes a staircase legally defective in California?
Common grounds include risers or treads outside code dimensions, variation of more than 3/8 inch between risers in the same flight, a missing handrail or one outside the 34 to 38 inch range, inadequate lighting, worn or slippery nosings, and accumulated debris or water. The applicable code is generally the edition in force when the stairway was built or permitted.
How long do I have to file?
Two years from the date of the fall for private property, under Code of Civil Procedure section 335.1. If a government entity owns the property, you must present a claim within six months under Government Code section 911.2, and then file suit within six months of the rejection under section 945.6.
What if my landlord knew the stairs were dangerous?
That strengthens the claim considerably. For common areas the landlord is responsible for conditions it knew about or should have discovered through reasonable inspection. For areas inside your unit, actual knowledge is generally required, which is why a written repair request is valuable evidence.
Does it hurt my case if I was carrying something or distracted?
It may reduce recovery but does not end the claim. California uses pure comparative negligence, so if you are assigned a share of fault your damages are reduced by that percentage rather than eliminated.
