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.
