Sources and Authority

Right to Repair Act Affirmative Defense of Homeowner’s Failure to Mitigate. Civil Code section 945.5(b).

“Although the Act establishes various maximum time periods in which the builder may respond, inspect, offer to repair, and commence repairs, the builder avails itself of the full time allowed by the Act at its peril. The builder is liable for the damages its construction defects cause, and even when a homeowner has acted unreasonably in failing to limit losses, the builder remains liable for ‘damages due to the untimely or inadequate response of a builder to the homeowner’s claim.’ (§ 945.5, subd. (b).) What constitutes a timely response will vary according to the circumstances, and the maximum response periods set forth by the Act do not necessarily insulate a builder from damages when the builder has failed to take remedial action as promptly as is reasonable under the circumstances. The Act’s liability provisions thus supply builders and homeowners clear incentives to move quickly to minimize damages when alerted to emergencies.” (McMillin Albany LLC v. Superior Court (2018) 4 Cal.5th 241, 257–258 [227 Cal.Rptr.3d 191, 408 P.3d 797].)
