California construction statutes confer substantial rights on property owners and contractors.
Property owner rights
An owner’s right is to construction that satisfies building codes, the approved plans, and Civil Code § 896. When work falls short, owners can pursue claims for repair costs, diminished value, and consequential damages.
Contractor rights
Contractors have the right to timely payment, including the protections in SB 440 (2% monthly interest on late payments) and SB 61 (5% retention cap). Licensed contractors also have access to mechanic’s liens, stop notices, and bond claims.
Key statute
How California Law Applies
The legal standards for substandard workmanship claims 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 usually proceed in stages: pre-litigation notice and inspection, mediation, and if those fail, litigation or arbitration. Claim type and contract provisions drive which procedural elements apply.
What Documentation Matters
Critical evidence typically includes the contract itself, change orders, payment records, inspection reports, project correspondence, photographs of defective work, building permits, and expert reports.
