California’s AB 1903 died at the Aug. 31 legislative deadline despite receiving no opposing floor votes, leaving proposed changes to the state’s construction-defect procedures unfinished. The Senate passed the measure 40-0 that night after the Assembly had approved it 70-0 in May, but lawmakers never completed the required Assembly concurrence vote on the Senate amendments before the session ended, according to reporting on the bill’s last-minute collapse.
Existing construction-defect rules remain in place in California, while the debate over whether liability reform could encourage more condominium and townhome construction is likely to continue. The issue reaches beyond California: high-cost markets across the country face a similar challenge when new multifamily construction adds rental housing without expanding lower-cost ownership options.
What happened to AB 1903
AB 1903, authored by Assemblymembers Buffy Wicks and Lori Wilson, addressed California’s procedures for resolving residential construction-defect claims. The official legislative record shows that the amended measure returned to the Assembly after its Aug. 31 Senate vote and was listed as “Held at Desk” on Sept. 2.
Supporters argued that litigation exposure and insurance costs discourage developers from building for-sale multifamily housing. Consumer attorneys and homeowners associations raised concerns that broader versions of the legislation could weaken homeowners’ ability to pursue legitimate defect claims.
By the final days of the session, lawmakers had stripped out several of the proposal’s broader provisions and focused more narrowly on prelitigation procedures and repairs.
Why California condo construction has lagged
Construction-defect liability is one factor developers and housing researchers have identified in California’s limited condo pipeline. Research commissioned by UC Berkeley’s Terner Center found that developers often pay three to four times as much for liability insurance on condominium projects as for comparable rental apartments.
Economic & Planning Systems estimated that construction-defect-liability-related expenses add about 1.9% to 4.4% to hard costs for a typical Los Angeles condo project. That amounts to roughly $8,100 to $18,300 per unit in 2024 dollars.
The study relied heavily on interviews with developers, insurers, architects, attorneys, and other industry professionals, while comprehensive statewide litigation data remain limited. Liability is better viewed as one potential barrier to condo development rather than the sole explanation for California’s shortage.
What the final bill would have changed
The final Aug. 28 bill text would have required claimants to provide builders with more detailed descriptions and available evidence of alleged defects before litigation. Builders and claimants also could have agreed to a release or waiver in exchange for repair work, with the release taking effect one year after repairs were completed.
Beginning July 1, 2027, insurers would have been barred from refusing to count certain repair costs toward a deductible or self-insured retention. Broader changes proposed earlier in the legislative process were removed before the final Senate vote.
None of those provisions will take effect after the bill failed to clear its final procedural step.
What AB 1903’s failure means for buyers
The bill’s collapse does not immediately change condo prices, inventory, buyer protections, or projects already under development. Condos can provide a lower-cost ownership option than detached homes in expensive markets, but changing liability rules alone would not guarantee additional construction or lower prices.
Buyers are also contending with rising HOA costs and special assessments, which can reduce the affordability advantage of a lower purchase price. Agents should review association finances, insurance expenses, assessments, and current condo reserve requirements alongside local resale inventory and confirmed new-construction pipelines.
Any successor legislation would reopen the same debate over development costs, defect claims, and homeowner protections — and whether easing barriers to condo construction can meaningfully expand the supply of homes buyers can own rather than rent.
