Responsible when construction creates a dangerous property

Who is Responsible When Construction Creates a Dangerous Property Condition?

October 3, 2026

A building can contain a dangerous construction problem even after the work is finished and the property is open. When someone gets hurt, a premises liability lawyer may need to determine whether the problem came from the property owner, a contractor, a subcontractor, or the original design.

California law looks at who controlled the property, who created the dangerous condition, and who knew or should have known about it. An investigation may also examine who had the ability to fix the problem before someone was injured.

How California Premises Liability Law Works

California Civil Code section 1714 establishes the state’s general duty to use reasonable care. In a premises liability case, an injured person generally must show that the defendant owned, leased, occupied, or controlled the property and was negligent in using or maintaining it.

When an unsafe condition causes an injury, California’s civil jury instructions also look at whether the condition created an unreasonable risk of harm. Another question is whether the defendant knew, or reasonably should have known, about the danger and failed to repair it, protect people from it, or provide a warning.

Construction can complicate this analysis because the company that created the hazard may no longer control the property when the injury occurs.

How Construction Can Create a Premises Liability Claim

Consider a shopping center that replaces an outdoor staircase. An architect prepares the design, while a general contractor oversees construction and a subcontractor pours the concrete.

Months later, rainwater begins collecting on one of the landings and someone falls.

The problem could have started with the design. The contractor may have failed to follow the plans, or the subcontractor may have built the landing at the wrong slope.

Responsibility may also extend to the owner or property manager. If they knew that water collected on the stairs and failed to address it, their conduct can become part of the case.

The Property Owner and Property Manager

Property owners often have the power to inspect dangerous areas and arrange repairs. California law does not require them to prevent every injury, but they must use reasonable care under the circumstances.

An owner can sometimes be liable when a dangerous condition existed long enough that a reasonable inspection should have found it. Repeated complaints, repair requests, or earlier incidents can also show that the owner had notice of the problem.

A property management company may face similar questions when it controls the area or handles maintenance.

The management agreement can help show who was responsible for inspections, repairs, and complaints. If a manager repeatedly receives reports about a loose railing but does nothing before it fails, that history can become important evidence.

The General Contractor and Subcontractors

A contractor can sometimes be responsible when poor construction creates a hazard that later injures someone.

California does not automatically protect a contractor simply because the project has been completed. However, the state’s completed-and-accepted doctrine can limit some claims involving defects that were visible and could have been found through a reasonable inspection before the owner accepted the work.

Hidden defects can be treated differently.

For example, bolts inside a railing may have been installed incorrectly but remain impossible to see during a normal inspection. If the railing later gives way, investigators may need to determine whether the problem could reasonably have been discovered earlier.

Subcontractors can also face responsibility for the part of the project they performed. A railing failure could lead investigators to the railing installer, while a dangerous walking surface could require examining the concrete or flooring work.

Construction plans, contracts, photographs, and inspection records can help show what each company was supposed to do and what was actually built.

Architects and Design Professionals

Some hazards begin with the design rather than the construction.

An architect or engineer may prepare plans that create poor drainage, an unsafe stair layout, or another condition that exposes people to injury.

California courts have recognized that design professionals can sometimes owe duties to people who were not parties to the original design contract.

Determining whether the problem came from design or construction often requires comparing the plans with the finished building. If the contractor ignored safe plans, the construction work may be the focus. If the contractor followed the plans and the dangerous feature was built as designed, the design itself may require closer review.

Building Code Violations

California building codes and local ordinances can provide important evidence in a construction-related injury case.

Improper stair dimensions, unsafe guardrails, badly installed handrails, and dangerous walking surfaces can all raise code questions.

Under California Evidence Code section 669, violating a statute or regulation can create a presumption of negligence when certain requirements are met. The violation must have caused the type of injury the rule was intended to prevent, and the injured person must be within the group the rule was designed to protect.

Passing an inspection does not automatically establish that a property was safe. Premises liability still depends on whether reasonable care was used under the circumstances.

Visible and Hidden Defects Can Affect Filing Deadlines

California law distinguishes between patent and latent construction defects.

A patent defect is one that should be discovered during a reasonable inspection. Code of Civil Procedure section 337.1 generally creates a four-year outside limit for certain claims involving patent defects, including personal injury and wrongful death claims.

A latent defect is hidden and would not normally be discovered through a reasonable inspection.

Code of Civil Procedure section 337.15 creates a 10-year limit for certain latent construction-defect claims. However, the California Supreme Court has held that this 10-year rule does not bar direct personal injury or wrongful death claims caused by latent defects.

Other filing deadlines can still apply. California’s general statute of limitations for negligence-based personal injury claims is usually two years.

Because these rules can overlap, the age of a building by itself does not determine whether a claim is still available.

Different Rules Apply to Some Construction Workers

California uses a different framework when the injured person works for an independent contractor on the property.

Under the Privette doctrine, the person or company that hires an independent contractor generally delegates responsibility for the contractor’s worker safety to that contractor.

There are exceptions. Under Hooker v. Department of Transportation, a hirer may face liability when it keeps control over part of the work and actually uses that control in a way that contributes to the injury.

Under Kinsman v. Unocal Corp., a landowner can also face liability for a concealed, preexisting hazard when the owner knew or should have known about it and the contractor could not reasonably discover it.

These rules can make a worker’s case different from one involving a customer, tenant, hotel guest, or other visitor.

More Than One Party Can Be Responsible

A construction-related premises liability case can involve several parties.

An architect may have designed an unsafe feature. A contractor may have built it incorrectly. The owner may have accepted the work, while the property manager later ignored complaints.

California’s comparative fault system can divide responsibility among multiple parties based on their contribution to an injury.

For that reason, investigating a construction-related injury often requires looking beyond the property owner. Plans, permits, contracts, inspection reports, repair records, and photographs can help show who created the condition and who had the opportunity to correct it before someone was hurt.
