Los Angeles Condo Construction After AB 1903 Failed

Quick answer: Los Angeles condo construction will not get immediate relief from California’s construction-defect liability rules after AB 1903 failed to receive final Assembly concurrence before the 2026 legislative deadline. The bill would have changed parts of the Right to Repair Act by requiring more detailed prelitigation defect notices, requiring claimants to show a violation caused by original construction, allowing certain repair-related releases, and adding an insurer rule scheduled for July 1, 2027. For Los Angeles homeowners and developers, the practical result is that new for-sale multifamily projects remain harder to finance, insure and pencil than comparable rental projects.

AB 1903 was a 2026 California Assembly bill by Assemblymembers Buffy Wicks and Lori D. Wilson that proposed amendments to Civil Code construction-defect procedures affecting new residential ownership housing, including condominiums, townhomes and other dwellings subject to California’s Right to Repair Act.

Why does Los Angeles condo construction matter now?

Los Angeles condo construction matters because condominiums are one of the few urban housing types that can create ownership opportunities without requiring every buyer to purchase a detached single-family home. In a city where land costs, financing costs, parking rules, building-code complexity and entitlement risk already make development difficult, the decline of condo production narrows the ladder into homeownership.

The Los Angeles Times reported on September 11, 2026 that California condo production has fallen dramatically since the early 2000s and that advocates point to construction-defect litigation risk as a central reason. The article cited Terner Center research showing that from 2011 to 2021, only 3% of California’s new multifamily units were condos, compared with 38% in Canada.

That gap is important for Los Angeles because much of the region’s best infill housing land is not suited to low-density ownership models. If new multifamily construction is almost entirely rental, renters gain more choices, but households looking for entry-level ownership are pushed toward older condos, distant suburbs, smaller single-family homes, or continued renting.

What did AB 1903 try to change for Los Angeles condo construction?

AB 1903 tried to reduce litigation uncertainty around construction-defect claims while preserving a homeowner’s ability to seek repairs or pursue claims when statutory conditions are met. The final August 28, 2026 bill text proposed to amend Civil Code Sections 910 and 942, add Sections 942.2, 945.1 and 945.6, add a severability chapter beginning at Section 945.9, and repeal and add Civil Code Section 926.

Under the bill text, a claimant’s prelitigation notice would have needed to include the claimant’s contact information, a reasonably detailed description of the alleged violation and its location, and reasonably available evidence such as photos, estimates or reports. The bill also would have required a claimant to affirmatively demonstrate that an applicable standard was violated and that the violation was caused by the original construction.

Another major change was the proposed repair-release provision. AB 1903 would have allowed a builder, with the claimant’s agreement, to obtain a release or waiver in exchange for repair work, effective one year after the repair was completed. The bill also stated that, effective July 1, 2027, an insurer could not treat repairs as voluntary payments or deny that repair costs count toward a deductible or self-insured retention.

What is the Right to Repair Act and why is it central to Los Angeles condo construction?

The Right to Repair Act is the California construction-defect framework created by SB 800 in 2002 and codified primarily in Civil Code Sections 895 through 945.5. SB 800 was approved and filed with the Secretary of State on September 20, 2002, and applies to original residential construction intended to be sold as individual dwelling units, with condominium conversions treated separately under the statute.

The law was designed to define construction standards, give homeowners a process for raising claims, and give builders an opportunity to inspect and repair alleged defects before litigation. In practice, housing researchers and industry groups argue that the law’s long claim window, broad defect categories and HOA litigation dynamics have made new condo projects unusually risky compared with rental apartments.

The Terner Center’s 2024 policy brief states that California construction-defect liability can apply for ten years once construction is complete, compared with four years for rental housing, and that this liability environment particularly affects townhomes and condominiums. Its later 2025 analysis found that insurance-related costs for condo builders can be three to four times those for similar rental apartment projects, with Los Angeles condo insurance costs estimated at $8,000 to $18,000 more per unit than rental units.

What is the status of AB 1903 as of September 12, 2026?

As of September 12, 2026, AB 1903 had not become law. Official legislative records show that the bill passed the Assembly 70-0 on May 26, 2026, passed the Senate 40-0 on August 31, 2026, and was then in the Assembly “Held at Desk” on September 2, 2026.

The important procedural point is that the Senate amended the bill before passing it, so it needed final Assembly concurrence. According to the Los Angeles Times and CalMatters, that final vote did not happen before the legislative deadline, leaving the reform unfinished for the 2026 session.

Because AB 1903 did not pass both houses in final form and was not signed by the governor, it has no operative effective date. The only precise future date in the final bill text was July 1, 2027, when the proposed insurer rule would have begun if the bill had become law.

How does this affect Los Angeles homeowners, HOAs and developers?

For Los Angeles homeowners and HOAs, the existing Right to Repair Act framework remains in place. Owners of newer condos and townhomes should continue documenting suspected construction defects, following statutory notice procedures, reviewing governing documents and warranties, and consulting qualified legal counsel when claims may involve deadlines or association authority.

For Los Angeles developers, the bigger issue is project feasibility. A small-lot subdivision, townhome project or mid-rise condo building must be underwritten not only for construction cost, interest carry, sales absorption and city approvals, but also for construction-defect insurance, quality-control costs, subcontractor availability and post-completion risk.

For architects and design-build teams, the lesson is not to avoid ownership housing altogether. It is to treat constructability, waterproofing, field coordination, detailing, peer review, inspection sequencing and record documentation as core feasibility issues from day one, not as late-stage construction administration tasks.

Key Takeaways

• AB 1903 was a 2026 construction-defect reform bill focused on California residential ownership housing, including condos and townhomes.
• The bill passed the Assembly 70-0 and the Senate 40-0, but did not receive the final Assembly concurrence needed after Senate amendments.
• The final bill text would have changed Civil Code Sections 910 and 942, replaced Section 926, and added Sections 942.2, 945.1, 945.6 and 945.9.
• The Right to Repair Act created by SB 800 remains the governing framework for covered new residential construction-defect claims.
• For Los Angeles condo construction, the failed bill means insurance, litigation-risk and quality-control issues remain central to project feasibility.

What should Los Angeles property owners consider before planning for-sale housing?

Los Angeles property owners should evaluate whether a for-sale project is feasible under today’s legal, insurance and permitting conditions before assuming condo sales will outperform rental housing. Zoning capacity is only one part of the equation; the ownership structure, construction-risk profile and exit strategy can change the entire pro forma.

On some sites, a new rental apartment building may remain the most financeable product. On others, a small-lot subdivision, townhome-style condominium, duplex strategy, SB 9 project or ADU/JADU program may provide a better balance between risk and value creation.

Owners should also understand that “condo” is a legal ownership form, not just a building shape. A stacked-flat building, attached townhome, mixed-use project or small-lot infill development can each trigger different design, mapping, HOA, insurance and disclosure considerations.

How can 121 Design Build help with Los Angeles condo construction decisions?

121 Design Build helps Los Angeles owners and developers test the architectural, permitting and construction realities behind ownership-housing ideas before major capital is committed. That includes site analysis, unit planning, code review, entitlement strategy, construction coordination and permit-ready design packages.

For ground-up projects, our New Construction team can evaluate density, unit mix, circulation, parking, building-code constraints and constructability. For smaller ownership or family-compound strategies, our SB9 and ADU & JADU services can help owners compare lower-risk ways to add for-sale or rentable housing value. For older properties where repositioning may be more practical than ground-up development, our Addition & Remodel service can assess what can be preserved, expanded or converted.

The best next step is a feasibility conversation that looks at the parcel, zoning, target buyer or renter, construction budget, permitting path and risk profile together. To discuss a Los Angeles site, contact 121 Design Build at our contact page or call (424) 600-2100.

Frequently Asked Questions

Did AB 1903 become law in California?

No. AB 1903 passed the Assembly and Senate unanimously in recorded floor votes, but after Senate amendments it did not receive final Assembly concurrence before the 2026 legislative deadline.

Does the failed bill change current condo defect rules?

No. Because AB 1903 did not become law, California’s existing Right to Repair Act procedures remain in place for covered new residential construction, including many new condos and townhomes.

Why are fewer condos being built in Los Angeles and California?

Researchers point to several factors, including construction costs, financing conditions, entitlement complexity and construction-defect liability risk. The Terner Center has specifically identified insurance and litigation risk as a major barrier to new condo and townhome production.

Would AB 1903 have eliminated homeowner defect rights?

No. The final bill text did not eliminate homeowners’ ability to bring defect claims. It would have required more specific prelitigation documentation, required proof that the violation was tied to original construction, and allowed certain repair-related releases by agreement.

Should Los Angeles developers still consider condo projects?

Yes, but only after careful feasibility review. Condo projects may still work on certain sites and price points, but ownership housing requires early attention to insurance, construction detailing, quality assurance, documentation and legal structure.
