In California, a contractor can be held liable for their work for anywhere from two to ten years after the job, depending on what went wrong and what kind of claim you bring. A written contract carries a four-year deadline. An oral one, two. Hidden construction defects are capped at ten years from substantial completion, no matter when you find them. Personal injury from bad work has to be filed within two years. Knowing which clock applies to your situation is often the single most important question in a construction dispute, because missing the right deadline ends an otherwise valid claim on the spot.
The Ten-Year Ceiling for Hidden Defects
The longest a California contractor can generally be held liable is ten years. Code of Civil Procedure 337.15 imposes an absolute statute of repose for latent construction defects, measured from the project’s substantial completion.1California Legislative Information. California Code of Civil Procedure 337.15 Latent defects are the ones that aren’t visible on reasonable inspection: foundation problems, water intrusion behind walls, concealed structural or plumbing failures. No matter how late you discover the problem, you cannot sue after ten years.
Substantial completion is fixed by whichever of the following happens first: final inspection by a public agency, recording of a notice of completion, occupancy of the improvement, or one year after work stopped.1California Legislative Information. California Code of Civil Procedure 337.15 Whichever date comes first starts the ten-year clock ticking.
Inside that ten-year window a shorter clock also runs. Once you discover a latent defect, or reasonably should have discovered it, Code of Civil Procedure 338 gives you three years to file suit.2Judicial Branch of California. Deadlines to Sue Someone The “should have discovered” language matters. If ceiling stains appeared two years ago and you ignored them, a court may start your clock from when the stains first showed up, not from when you finally called an inspector. So the practical rule is this: you have three years from discovery, but you can never sue more than ten years after substantial completion, whichever comes first.
Visible Defects: Four Years From Completion
A patent defect is a problem visible through reasonable inspection: a poorly finished floor, misaligned cabinetry, an obviously uneven roofline. Under Code of Civil Procedure 337.1, patent defect claims must be filed within four years of the project’s substantial completion.3Justia. CACI No. 4550 – Affirmative Defense – Statute of Limitations – Patent Construction Defect This is a firm date tied to completion, not to when you noticed. The reasoning is straightforward: if a defect was visible from the start, the law expects you to act on it within a reasonable period.
Breach of Contract: Four Years Written, Two Years Oral
Most construction disputes end up as contract claims. If your agreement was written, Code of Civil Procedure 337 gives you four years from the date of the breach to sue.4California Legislative Information. California Code of Civil Procedure CCP 337 The clock starts when the breach happens, not when the project wraps up. If a contractor agreed to use a specific grade of material and substituted something cheaper, the four years begin on the day of the substitution, even if you didn’t discover it until later.
Oral contracts get half the time. Code of Civil Procedure 339 allows only two years from the date of breach.2Judicial Branch of California. Deadlines to Sue Someone Most construction projects involve at least some paperwork, but verbal side deals about extras or change orders can fall into this category. A handshake promise has a much shorter enforcement window than a signed one.
The same defect can support both a contract claim and a defect claim, and the two deadlines can expire on different dates. It’s worth checking both before assuming you’re out of time.
Injury and Property Damage From Negligence
A contractor can also be liable in negligence, separate from anything the contract says. California Civil Code 1714 establishes a general duty of care.5California Legislative Information. California Civil Code 1714 The deadline depends on what was harmed:
- Property damage: three years from the damage, under Code of Civil Procedure 338.2Judicial Branch of California. Deadlines to Sue Someone
- Personal injury: two years from the injury, under Code of Civil Procedure 335.1.6California Legislative Information. California Code of Civil Procedure 335.1
This distinction trips people up. If a badly installed balcony collapses and hurts someone, the property damage claim has three years and the injury claim has two. Miss the shorter one and the injury claim is gone, even if the property damage claim survives.
One limit on negligence claims worth knowing: California’s economic loss rule blocks recovery of purely financial losses in negligence when no physical property damage or bodily injury occurred. In Aas v. Superior Court (2000), the California Supreme Court held that construction defects must cause actual property damage before they become actionable in negligence. If a defect only reduces your home’s value but hasn’t yet caused physical harm, your remedy lies in contract or warranty law.
Implied Warranties When the Contract Is Silent
Even when a contract says nothing about quality, California recognizes implied warranties that the work will be performed in a reasonably workmanlike manner and that the finished product will be fit for its intended use. The California Supreme Court anchored the workmanship principle in Pollard v. Saxe & Yolles Dev. Co. (1974), holding that builders of new construction impliedly represent that the structure was designed and built with reasonable skill.7Justia. Pollard v Saxe and Yolles Dev Co For residential work, the implied warranty of habitability guarantees the home is fit for human habitation and free from substantial defects, and a contractor cannot simply disclaim it.
Implied warranty claims run on the same defect timelines: three years from discovery and the ten-year outer limit under Code of Civil Procedure 337.15.1California Legislative Information. California Code of Civil Procedure 337.15 Express written warranties are enforced by their own terms and follow the four-year written-contract deadline.
When the Ten-Year Cap Doesn’t Protect the Contractor
Two exceptions can extend liability beyond ten years. The statute of repose does not shield a contractor who engaged in willful misconduct or fraudulent concealment. If a contractor deliberately hid shoddy work, the ten-year protection falls away entirely. The statute also does not apply to a person who owns or controls the improvement at the time the defect causes harm. These carve-outs are narrow, but when they apply, a claim can stay alive well past the decade mark.
CSLB Complaints and Bond Claims Have Their Own Windows
Beyond the courthouse, two administrative routes carry separate deadlines.
The Contractors State License Board investigates violations of contractor license law, whether the contractor is licensed or not, for up to four years from the date of the act or omission.8CSLB. Filing a Construction Complaint CSLB can suspend or revoke a license and impose discipline, but its focus is public protection rather than getting your money back. A finding against the contractor can still strengthen a private lawsuit.
Every licensed California contractor must carry a $25,000 license bond, which exists to compensate parties harmed by the contractor’s work.9CSLB. Bond Requirements Bond claims cover things like willful departure from accepted trade standards, deliberate code violations, and fraud. The deadline is two years after the expiration of the license period during which the violation occurred. The surety has 40 days to investigate a written demand before accepting or denying it. The $25,000 is shared across all claimants for a given license period, so it may not cover everyone if multiple owners file.
The Right to Repair Notice Requirement
For newer residential construction, you can’t just file suit when the deadline is approaching. The Right to Repair Act (Civil Code 895–945.5) requires the homeowner to send written notice of the alleged defect to the builder by certified mail, overnight delivery, or personal delivery before litigation.10California Legislative Information. SB 800 Senate Bill – CHAPTERED The builder then has a right to inspect and offer repairs. Only if the builder fails to respond, or the homeowner reasonably rejects the offer, can the case move forward.
Boundary worth knowing: the Right to Repair Act applies only to new residential units where the purchase agreement was signed on or after January 1, 2003.11CSLB. Construction Defect Notice to Owners of New Residential Single-Family Dwellings Older homes, homes purchased before that date, and remodeling or renovation work on existing homes fall outside the statute. Those disputes proceed under the general common law framework.
Don’t Let Negotiation Run Out the Clock
The most common mistake in construction disputes is assuming you have time while you try to work it out. You often don’t. Mediation, arbitration preparation, and CSLB complaints do not pause the statute of limitations unless the parties sign a written tolling agreement. If your deadline is approaching, file first and negotiate after. A filed lawsuit can be paused, dismissed, or settled. A missed deadline cannot be undone.
