Statutes of Limitation & Repose

California draws a sharp line between patent defects (apparent by reasonable inspection) and latent defects (not apparent by reasonable inspection) and applies a different outer time limit to each:

• Patent defects: a four-year outer limit under Code of Civil Procedure section 337.1, running from substantial completion.
• Latent defects: a ten-year outer limit under Code of Civil Procedure section 337.15, a true statute of repose running from substantial completion (as defined by the earliest of final inspection, recorded notice of completion, occupancy, or one year after work ceases).
• Right to Repair Act claims: generally subject to the same ten-year outer boundary under Civil Code section 941, layered on top of the pre-litigation process described below.

The California Supreme Court's decision in Lantzy v. Centex Homes (2003) held that ordinary equitable tolling does not extend the ten-year period under section 337.15, reinforcing that this deadline functions as a hard outer boundary, not a flexible one. That makes early forensic investigation a genuine strategic factor, not just a formality: evidence and access to a site both degrade with time and a claim that's forensically strong today can become materially harder to support as records, witnesses and physical conditions change.

Confirming which limitations period applies and how close a matter is to its outer boundary is one of the first things worth establishing on any California construction matter. If you're evaluating a potential claim, earlier forensic involvement generally preserves more evidentiary options than later involvement.

The Right to Repair Act (SB 800)

For new residential units first sold after January 1, 2003, the Right to Repair Act (Civil Code section 895 et seq.) is the controlling framework for construction defect claims and the California Supreme Court confirmed in McMillin Albany LLC v. Superior Court (2018) that it provides the exclusive remedy for claims within its scope. The Act breaks down into four parts:

• Construction standards (§§896–897): function-by-function performance standards covering water intrusion, structural integrity, mechanical systems and exterior elements, among others.
• Builder obligations & warranties (§§900–907): what a builder is responsible for and for how long.
• Pre-litigation process (§§910–938): a mandatory, non-adversarial notice-and-opportunity-to-repair procedure a homeowner must follow before filing suit, including written notice of the alleged violation, builder inspection rights and a repair offer window.
• Lawsuit procedure (§§941–945.5): the rules that govern an actual filed claim once the pre-litigation process has run its course.

For attorneys and insurers, the practical effect is that a forensic evaluation on a post-2003 residential matter usually needs to speak directly to the section 896 standards (not just to whether something looks wrong, but to which specific enumerated standard it violates) because that's the vocabulary the pre-litigation process and any resulting claim will be argued in.

PCC's forensic reports on Right to Repair matters are built to map directly onto the section 896 standards, so findings translate cleanly into the pre-litigation notice and, if needed, into deposition.

Contractor Licensing & Compliance

California regulates contractors statewide through the Contractors State License Board (CSLB). Licensing status is frequently more than a formality in a California construction dispute:

• Business & Professions Code §7031(a): bars an unlicensed contractor from suing to collect compensation for work requiring a license, regardless of the merits of the underlying work.
• Business & Professions Code §7031(b): separately allows the party who paid an unlicensed contractor to sue to recover all compensation paid, even where the work performed was otherwise adequate.
• License status verification: a certified CSLB licensure history is generally the standard form of admissible proof of a contractor's licensed status during the relevant period.

Because licensure findings can materially change a damages picture (independent of whether the underlying construction work itself was defective), confirming licensing status against CSLB records is a standard early step in PCC's forensic intake on California matters.

Site Safety & Premises Liability

Cal/OSHA (the regulations found in Title 8 of the California Code of Regulations, enforced by California's Division of Occupational Safety and Health) governs workplace safety on active construction sites and frequently intersects with premises liability and site-condition claims. A forensic investigation touching an active or recently active job site typically needs to account for applicable Cal/OSHA requirements alongside local building codes and the standard of care in effect at the time of construction.
