California Construction Defect Statute of Limitations — How Long Do You Have?

The Two Most Important California Construction Statutes of Limitations

CCP §337.15 — The 10-Year Latent Defect Statute

California Code of Civil Procedure §337.15 provides that no action may be brought to recover damages from any person who develops real property, performs or furnishes the design, specifications, surveying, planning, supervision, or observation of construction, or construction of an improvement to real property more than 10 years after the substantial completion of the development or improvement.

This is the primary statute for latent (hidden) construction defects. "Substantial completion" is the key date — generally the date the work was functionally complete enough for its intended use, even if minor items remained to be finished. This is a statute of repose, not a statute of limitations: the 10-year period runs from substantial completion regardless of when you discovered the defect.

CCP §338 — The 3-Year Discovery Rule for Patent Defects

California Code of Civil Procedure §338 provides a 3-year limitation period for claims based on fraud, mistake, or patent (visible) defects. Unlike the 10-year period, this statute uses a discovery rule — the clock starts when you discovered or reasonably should have discovered the defect, not when it was created.

Latent vs. Patent Defects — Why the Distinction Is Critical

The difference between a latent and patent defect determines which statute of limitations applies — and can mean the difference between 3 years and 10 years to file your claim.

Patent defects are visible and discoverable through a reasonable inspection. A roof that is visibly sagging, tile work that is obviously uneven, paint that is peeling from bare wood — these are patent defects. If you did a reasonable inspection at completion and could have found the defect, it is patent.

Latent defects are concealed — you cannot find them without opening walls, testing systems, or waiting for failure to manifest. Improperly installed waterproofing that leaks years later, undersized structural members inside walls, improper pipe connections concealed in the ceiling — these are latent defects. The fact that a defect is inside a wall or ceiling is not automatically sufficient to make it latent; courts ask whether a reasonable inspection would have revealed it.

Many defects fall in a gray area. Whether a defect is latent or patent is a factual question that may need to be resolved by a court, which is why getting an independent expert's assessment early is so important.

Specific Deadlines by Claim Type

• Latent construction defects (CCP §337.15): 10 years from substantial completion — absolute bar regardless of discovery
• Breach of written contract (CCP §337): 4 years from the date of breach
• Breach of oral contract (CCP §339): 2 years from the date of breach
• Fraud and fraudulent concealment (CCP §338): 3 years from discovery of the fraud
• Negligence / patent defects (CCP §338): 3 years from discovery
• Home improvement fraud — BPC §7160: 3 years from the fraudulent act or discovery
• Unlicensed contractor disgorgement — BPC §7031: 2 years from discovery of unlicensed status
• Bond claims: Governed by the bond terms — typically 1 to 4 years; check the specific bond

How the Discovery Rule Works

For statutes of limitations that use the discovery rule (as opposed to the §337.15 repose period), the clock starts when you discovered — or in the exercise of reasonable diligence should have discovered — the facts giving rise to the claim. California courts apply an objective test: what would a reasonably diligent homeowner have done, and would that diligence have revealed the defect?

You cannot delay the clock by simply refusing to investigate. If a reasonable person would have had the work inspected, and that inspection would have revealed the defect, the clock starts at the point you should have had the inspection — not when you actually had it.

Conversely, a contractor who actively concealed a defect — for example, covering improper work with drywall or paint — may face a longer limitations period under the fraudulent concealment doctrine. California courts toll (pause) the statute of limitations for the period of concealment.

Tolling — When the Clock Pauses

California law recognizes several circumstances that pause (toll) the statute of limitations:

• Fraudulent concealment — when the contractor actively hid the defect
• Minority — if the homeowner was a minor at the time the claim arose
• Mental incapacity — if the homeowner was legally incapacitated
• Agreed tolling — if the contractor and homeowner signed a written tolling agreement (common during settlement negotiations)
• CSLB arbitration — the statute may be tolled during the CSLB arbitration process
