Both property owners and contractors in California hold significant rights under state construction statutes.
Property owner rights
Owners are entitled to construction meeting building codes, the approved plans, and Civil Code § 896 standards. When the work fails on those standards, owners can pursue repair-cost recovery, diminished value, and other damages.
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 defective materials 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
Disputes typically run through pre-litigation notice and inspection, mediation, and only then litigation or arbitration. Both claim type and contract provisions shape the specific process.
What Documentation Matters
Among the key documents are the construction contract, change orders, payment records, inspection reports, correspondence, photographs of defective work, building permits, and expert reports.
