California Poised for the Most Significant Residential Construction Defect Reforms in Decades

September 01, 2026 — Thomas D. Fama & Andrew J. Mallon - Wood Smith Henning Berman
The California Legislature is considering legislation that would dramatically alter the landscape of residential construction defect litigation. Assembly Bill 1903, currently pending before the Senate Judiciary Committee, proposes extensive amendments to California's Right to Repair Act (Civil Code sections 895-945.5) that would substantially strengthen procedural protections for builders while narrowing the scope of recoverable construction defect claims. If enacted, the legislation would affect virtually every stage of a construction defect dispute- from the initial notice of claim through litigation and settlement- and would introduce an entirely new certification process for newly constructed condominium projects. This article details some of the most significant proposed changes. Higher Burden for Construction Defect Plaintiffs Perhaps the most consequential change is the bill's modification of the proof required to establish liability. current law generally requires a claimant to demonstrate the residence fails to satisfy one of the statutory performance standards established under the Right to Repair Act. AB1903 would instead require claimants to establish three separate elements:

• A violation of an applicable statutory performance standard;
• The violation caused appreciable, present, non-speculative physical damage to another building component; and
• The violation resulted from the original construction.

Defend Now, Allocate Later? An Unresolved Tension in Colorado Construction Law

August 16, 2026 — David McLain - Colorado Construction Litigation Blog
For decades, Colorado law has recognized an important distinction between the duty to defend and the duty to indemnify. The former ordinarily arises at the beginning of litigation; the latter generally cannot be determined until the underlying liability is known. That distinction makes intuitive sense. A defense that becomes due only after litigation concludes is not much of a defense. But Colorado’s construction anti-indemnity statute, C.R.S. § 13-21-111.5(6), raises an interesting question about how that familiar rule operates in construction disputes. The statute expressly regulates contractual obligations not only to indemnify, but also to insure and defend, and it reflects a legislative policy that construction businesses should bear financial responsibility for their own negligence. Those principles have developed along separate tracks. At some point, a Colorado appellate court may have to decide precisely how they fit together. Read the full story...

From CERCLA to Drinking Water: D.C. Circuit’s PFAS Ruling Enters a Second Regulatory Fight

October 06, 2026 — Ashleigh K. Myers, Amanda G. Halter & Jillian Marullo - Gravel2Gavel Construction & Real Estate Law Blog
On August 18, 2026, a unanimous panel of the U.S. Court of Appeals for the D.C. Circuit upheld EPA’s designation of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund). In Chamber of Commerce of the United States v. EPA, the court rejected challenges to EPA’s interpretation of CERCLA Section 102(a), the adequacy of its notice and comment process, its analysis of costs and benefits, and its decision to proceed despite uncertainty about future response actions and costs. This decision is already being invoked in a separate D.C. Circuit challenge to EPA’s 2024 PFAS drinking water rule promulgated under the Safe Drinking Water Act (SDWA). Six days after the CERCLA decision, respondent intervenors cited it as supplemental authority in American Water Works Association v. EPA, No. 24-1188, ahead of oral argument scheduled for September 18, 2026. The Chamber of Commerce decision may assist the respondent intervenors on certain notice and comment and economic analysis arguments, but its significance should not be overstated. The principal challenges to the standards for the four PFAS subject to EPA’s Hazard Index-based maximum contaminant level (MCL) turn on requirements specific to the SDWA, and EPA itself now agrees that those provisions were promulgated through an unlawful process.

Louisiana Enacts Important Tort Reform Legislation

May 12, 2026 — Lee M. Peacocke & Benjamin Perkins - Lewis Brisbois
The Louisiana legislature enacted tort reform legislation in 2025 to address the increasing cost of insurance in Louisiana and to provide some predictability to the Louisiana legal system. While our colleagues, Jenny Michel and Jennifer Kretschmann, have provided an excellent and comprehensive analysis of the legislation in their article entitled “Louisiana State Legislature 2025 Regular Session: Tort Reform - Acts & Vetoed Insurance Bill,” which can be found here, this article examines the anticipated impact of the tort reform legislation on personal injury trials in federal and state courts in Louisiana. The most significant reform involves the institution of a modified defense of contributory negligence, which went into effect on January 1, 2026. Since 1996, Louisiana had operated as a pure comparative fault state; the liability of each party whose fault caused damages was to be allocated among the respective parties based upon their appropriate percentage of fault, regardless of the legal theory of liability asserted against each party. Thus, a plaintiff 55 percent at fault could recover 45 percent of their damages from the liable defendants. The 2025 Tort Reform Amendments now prohibit a plaintiff in a personal injury action from recovering any damages if they are found to be 51 percent or more at fault for their damages. The 55 percent at-fault party in the example above is now prohibited from recovering any damages from any party. Importantly, this new legislation now requires the trial court to instruct the jury that if they find a plaintiff to be more than 50 percent at fault, then the plaintiff will not recover any damages.

At the Frontier of Change: How—or Where—to Rebuild as Alaska's Permafrost Disappears

September 28, 2026 — Pam McFarland - Engineering News-Record
In some areas of the tiny subsistence coastal village of Kwigillingok along the Bering Sea in western Alaska, pockets of ground feel squishy, almost gelatinous, rather than solid. It’s an odd sensation, as if there is only a thin layer of muddy soil preventing people from falling into the water beneath their feet. Read the full story...

Potential Gap in Workers Compensation Immunity Statutory Framework

June 02, 2026 — David Adelstein - Florida Construction Legal Updates
Workers compensation insurance is important. As an owner, you want to ensure the contractors you hire have workers compensation insurance. Assuming you hire a contractor that is statutorily exempt from workers compensation, you want to make sure, no exception, that any subcontractor that is hired has workers compensation insurance. (Regardless, you always want subcontractors to have workers compensation insurance.). In construction, the prime contractor serves as the “statutory employer” for purposes of workers compensation insurance. With workers compensation comes workers compensation immunity.
