Frequently Asked Questions

How long do I have to sue a contractor in California? +

For a written contract, generally 4 years from the date of breach or substantial completion (CCP §337). For an oral contract, generally 2 years (CCP §339). For latent construction defects not visible at completion, the discovery rule may extend the period from when you discovered the problem — but not beyond 10 years from substantial completion (CCP §337.15).

Does the discovery rule apply to contractor lawsuits in California? +

Yes. For latent defects — problems not reasonably discoverable at completion — the statute of limitations may start when you discovered the problem rather than when work ended. However, the 10-year statute of repose under CCP §337.15 sets an outer limit. Consult an attorney to determine whether the discovery rule applies to your specific facts.

What is the deadline if my contractor is unlicensed? +

For a BPC §7031 recovery claim against an unlicensed contractor, the standard limitations periods apply (4 years for written, 2 years for oral). However, courts have interpreted the accrual date differently in some cases. An attorney should review BPC §7031 claims, especially where significant time has passed.

Is there a separate deadline for a CSLB complaint? +

CSLB complaints are not subject to the civil statute of limitations — however, the CSLB has its own investigation standards and may give less weight to old complaints. Filing promptly is always advisable. A CSLB complaint and a civil lawsuit are separate processes and can proceed simultaneously.

Can I still sue if the statute of limitations has expired? +

Generally, no — an expired limitations period is a complete defense. However, exceptions exist: fraudulent concealment by the contractor, absence from the state, mental incapacity, and other equitable tolling doctrines may extend the period. If you believe the contractor actively concealed the problem, consult an attorney immediately — do not assume your claim is time-barred without a professional review.
