Property owners and contractors operating in California have substantial rights under the state’s construction law.
Property owner rights
Owners are entitled to work that complies with building codes, approved plans, and the standards in Civil Code § 896. When standards aren’t met, claims for repair cost, diminished value, and additional damages are available.
Contractor rights
Among contractor rights is timely payment, supported by SB 440 (2% monthly interest on late payments) and SB 61 (5% retention cap). Mechanic’s liens, stop notices, and bond claims are available enforcement mechanisms for licensed contractors.
Key statute
How California Law Applies
The legal standards for preliminary 20-day notice are established by California statute, building codes, and case law. Key statutes include Civil Code §895 et seq. (Right to Repair), Civil Code §8400 et seq. (mechanic's liens), BPC §7031 (contractor licensing), and the new SB 440 and SB 61 provisions effective 2026.
The Legal Process
California construction disputes generally move through pre-litigation notice and inspection, then mediation, and — if needed — litigation or arbitration. The specific procedural path turns on claim type and the contract’s dispute-resolution provisions.
What Documentation Matters
Important documents include the construction contract, change orders, payment records, inspection reports, correspondence, photos of defective work, building permits, and expert reports.
