Your Rights Under California Law

Under California construction law, property owners and contractors have substantial rights.

Property owner rights

Owners have the right to construction work that meets building codes, the approved plans, and the standards in Civil Code § 896. Where the work fails to meet those standards, claims for repair cost, diminished value, and other damages are available.

Contractor rights

Timely payment is a contractor right, with SB 440 imposing 2% monthly interest on late payments and SB 61 capping retention at 5%. Licensed contractors additionally have mechanic’s liens, stop notices, and bond claims as remedies.

Key statute

Cal. Civ. Code §895 — The Right to Repair Act establishes construction performance standards and pre-litigation procedures for residential construction defect claims in California.

How California Law Applies

The legal standards for water intrusion & moisture defects 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

Documentation that matters typically includes the construction contract, change orders, payment records, inspection reports, correspondence, photos of defective work, building permits, and expert reports.
