California Statewide Reference

California Construction Law

California has one of the most detailed construction-law frameworks in the United States. The substantive rules are statewide: Business and Professions Code §§7000–7999 governs contractor licensing through the Contractors State License Board; Civil Code §§8000–8848 governs mechanic's liens, stop payment notices, and payment bonds; SB 800 (Civil Code §895 et seq.) governs residential construction defects; and the prompt payment statutes in BPC §7108.5 and elsewhere set retention and pay-app deadlines.

Procedure changes from city to city — which courthouse hears the case, which county recorder takes the lien recording, which CSLB intake office investigates the complaint. This page is the statewide reference. City-specific procedure for the twenty most-asked-about California construction-law jurisdictions is linked below.

Practice-Area Guides

Eight core topic guides cover the substantive law that applies the same way in every California city.

Mechanic's Lien Law

The 20-day preliminary notice, the 90-day recording window under Civ. Code §8412, and how to record a lien that actually attaches under §8416.

Contractor Licensing — BPC §7031

The disgorgement statute that lets an owner recover everything paid to an unlicensed contractor — and the narrow substantial-compliance defense.

Contractor Payment Law

Prompt payment under BPC §7108.5, retention caps after SB 61, and stop payment notices under Civ. Code §8500 et seq.

Construction Defect Law — SB 800

The Right to Repair Act framework: pre-litigation notice under Civ. Code §910, builder response obligations, and the §896 standards.

Contractor Bond & Surety Law

The $25,000 CSLB license bond, public-works payment bonds under Civ. Code §9550, and how surety claims actually play out.

Homeowner Rights

Cancellation rights, deposit limits under BPC §7159, and remedies after a contractor walk-off or defective work.

Contractor Disputes

Demand letters, mediation, CSLB complaints, small claims, and when a dispute escalates to a civil suit.

Construction Litigation Process

From demand through trial: how a California construction case actually moves in practice.

Procedure by California City

Each city page below covers the same four procedural questions: which superior court hears the case, which county recorder takes the lien recording under Civ. Code §8416, which CSLB office routes complaint intake (Norwalk for Imperial/LA/Orange/Riverside/San Bernardino/San Diego/Ventura; Sacramento for everywhere else), and which city department issues the underlying building permit.

Key California Construction Statutes

Every guide and city page on Contractor Law cites these primary sources. Read the statute before relying on a deadline.

BPC §§7000–7999 — Contractors State License Law. Licensing, classifications, the home improvement contract rules (§7159), and disgorgement against unlicensed contractors (§7031).
Civil Code §§8000–8848 — Mechanic's Liens, Stop Notices & Payment Bonds. The full private-works payment-protection regime, including the 20-day preliminary notice (§8200), the 90-day lien deadline (§8412), and the foreclosure window (§8460).
Civil Code §§9000–9566 — Public Works Payment Bonds. The parallel public-works framework: stop payment notices under §9350 and payment bond claims under §9550.
Civil Code §895 et seq. — Right to Repair Act (SB 800). Pre-litigation defect notice (§910), the builder's right to inspect and repair (§916), and the building standards (§896).
BPC §7108.5 — Prompt Payment. Down-stream prompt-payment obligations from contractors to subcontractors and the penalties for noncompliance.
Code of Civil Procedure §337.15 — Latent Defect Statute of Repose. The 10-year outer limit on latent construction defect claims.

What Changed in 2026

Two recent statutes meaningfully reshape the California payment-protection landscape:

  • SB 440 (effective Jan. 1, 2026) — codified change-order claims process. Owners and contractors on private works now have a defined notice and response protocol when a change order is in dispute, reducing the risk that work performed under a contested change order goes uncompensated.
  • SB 61 (effective Jan. 1, 2026) — caps construction retention at 5% on most private works, down from the prior unlimited contractual retention. Owners and contractors can still negotiate lower retention; what they can no longer do is retain a higher percentage by contract.
