Which statute of limitations applies to a construction defect case?

More than one limitations period can potentially apply to the same case, which is exactly where people commonly go wrong in evaluating their own deadline. California's Right to Repair Act, codified at Civil Code sections 895 through 945.5, establishes tiered limitation periods that vary specifically by the type of defect involved: generally four years for most function or component failures, meaning systems or parts that simply don't work as they're supposed to, and up to ten years for what the statute calls latent defects, meaning problems that remain hidden and only cause actual, visible property damage later on.

Both of these timeframes are measured from the date of substantial completion of the construction or the close of escrow on the sale, not from whenever you personally first noticed a problem, which is a critical distinction. The statute is more granular than a simple two-tier system, though. Plumbing and sewer system failures specifically carry their own four-year window under Civil Code section 896(e), while most structural components, foundations, framing, load-bearing walls, default to the full ten-year period unless a shorter window is separately listed. A handful of items, including paint, carpet, and certain appliances, carry their own separate, often shorter limitation windows, sometimes as brief as one year, so identifying exactly which category your specific defect falls into is an essential first step in determining your actual deadline.

There's also a separate, harder outer limit layered on top of all of this: Code of Civil Procedure section 337.15 sets a ten-year statute of repose, an absolute cutoff, for any claim involving a latent deficiency in the design or construction of a structure, running from substantial completion regardless of when the defect was actually discovered. Unlike an ordinary statute of limitations, a statute of repose generally cannot be paused or extended by later discovery of the problem, which makes it a hard ceiling on your claim rather than a flexible deadline.
