AB 1903 California Assembly · 2025-2026 Regular Session

Construction defects.

Summary
Existing law specifies the rights and requirements of a claimant or homeowner to bring a civil action for construction defects of a dwelling, including applicable standards for home construction, detailed prelitigation procedures, statute of limitations, burden of proof, and the damages recoverable. Existing law specifies the rights and prohibitions for a builder to defend against a civil action for construction defects, including a prohibition against a builder obtaining a release or waiver in exchange for repair work mandated by law. This bill would modify specific rights, requirements, and prohibitions for the parties to a civil action for construction defects of a dwelling by revising, among other things, the requirements for a prelitigation notice from the claimant to the builder and the evidence a claimant is required to affirmatively demonstrate to make a claim. Among other changes, the bill would repeal the prohibition on, and, instead, authorize, a builder to obtain a release or waiver in exchange for certain repair work, as specified. Commencing July 1, 2027, the bill would prohibit an insurer from asserting repairs as a voluntary payment or as a payment made without the insurer's consent, or denying counting the costs associated with those repairs, against a deductible or self-insured retention. The bill would provide that its provisions apply to structures subject to the provisions governing the rights of a claimant or homeowner to bring a civil action for construction defects of a dwelling, except as provided. The bill would further provide that its provisions are severable.

MINOR
This diff reflects a change in document presentation format rather than substantive policy content. The bill text transitions from a traditional legislative document layout (with page numbers, line numbers, and printed formatting) to a web-based bill text display that includes website navigation elements such as search boxes, links, and menu items. The underlying statutory language of AB 1903 on construction defects remains substantively unchanged between the two versions.
TECHNICAL

Page numbers (e.g., '92', '--2--') and line numbers were removed from the document as it was reformatted for web display.

Website navigation and interface elements were added, including links for 'skip to content,' 'home,' 'accessibility,' 'FAQ,' 'feedback,' 'sitemap,' 'login,' a quick search box, bill information links, and version selection dropdowns.

The amendment history was reformatted from individual lines listing each amendment date to a consolidated list format with consistent spacing.
