California Contractors Get a Much-Needed Break: SB 342 Softens the Harsh Consequences of Contractor License Lapses

October 20, 2026 — Heather Frisch - The Construction Seyt
Imagine completing a multimillion-dollar project, performing quality work, paying your subcontractors, and satisfying the owner, only to discover that a temporary contractor license lapse could prevent you from recovering payment for that work or pursuing claims for extra work. For decades, that was the reality under California Business and Professions Code section 7031. A contractor that allowed its license to lapse, even briefly, could face catastrophic consequences completely disconnected from the quality of its work. In some cases, a contractor that performed otherwise flawless work could be barred from recovering payment and even be ordered to disgorge compensation already received – even if the owner knew the contractor had a lapse in its licensing and allowed it to continue construction. That reality is about to change. 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.

The Goal Is the Repair, Not the Lawsuit: What Colorado HOA Boards Should Consider Before Suing a Builder

September 08, 2026 — Gail Gudder - Colorado Construction Litigation Blog
Fourteen years ago, we cautioned Colorado homeowners associations against a “ready, fire, aim” approach to construction-defect litigation. In The Hidden Dangers of Construction Defect Litigation, we suggested a fairly simple proposition: when legitimate construction defects exist, the goal should be to get them repaired. Litigation should be a last resort, not an end in itself. Much has changed in Colorado construction-defect law since then. But a recent Douglas County case, and significant amendments to the Colorado Common Interest Ownership Act (“CCIOA”) enacted in 2025, provide good reasons for HOA board members and owners to revisit that basic premise.

Construction Robotics Works Where Variation Ends

August 11, 2026 — Aarni Heiskanen - AEC Business
BuiltWorlds published its 2026 Robotics Top 50 this summer, and the list is genuinely wide. Fifty solutions across nine categories, from 3D printing and prefabricated component manufacturing to earthmoving, demolition, material transport, layout, installation, inspection, and drilling. The honorees come from sixteen countries. It looks like robotics has finally spread across the whole project lifecycle. However, having vendors in nine categories does not mean that contractors are robotizing their work en masse. Zacua Ventures, in its 2026 construction robotics report, estimates that on-site robotics accounted for less than 0.03% of global construction spending in 2025. Zacua says: “That is not a failed market. It is a market at the beginning of an adoption S-curve”, while warning that its estimates rest on private vendor data and may be high if vendors overstate how widely their machines are deployed.

From Dark Data to Building Intelligence

July 13, 2026 — Aarni Heiskanen - AEC Business
In this episode, I talk with Mark Sorsa-Leslie, founder and CEO of Auttaa AI, whose team just won first place in Luotea’s inaugural hackathon in Helsinki for turning property maintenance from reactive firefighting into proactive forecasting with AI. Mark is a chartered surveyor with 30 years of real estate data experience, previously the founder of the UK sensor company Beringar. We discuss why so much building data stays dark and siloed, from outdated networking technology to the shortage of people who understand both engineering and property. Mark explains how Auttaa bridges real-time building data with large language models, using what he calls an “influence graph” to surface correlations and causation across previously disconnected systems, such as linking occupancy patterns to CO2 readings to diagnose ventilation problems in minutes rather than days.

Building in Arizona’s Data Center Boom: How Federal Executive Orders, State Regulation, and National-Security Policy Are Reshaping the Rules for Developers

June 02, 2026 — Ryan J. Regula - Snell & Wilmer
Developers and practitioners evaluating data center projects in Arizona face a regulatory environment shifting on three fronts simultaneously. Federal executive orders are opening new land, streamlining permitting, and channeling financial incentives toward qualifying projects — but they are not preempting the state and local rules that most directly affect project economics. A carve-out in the December 2025 Artificial Intelligence (AI) Framework Executive Order preserves Arizona’s authority over data center infrastructure, meaning the Arizona Corporation Commission’s (ACC) rate-classification docket, municipal zoning restrictions, water-use ordinances, and pending grid cost-allocation legislation remain the binding constraints on project feasibility. Understanding where federal tailwinds end and state and local headwinds begin is essential for any developer sizing risk or selecting sites in the state. The Federal Landscape: An Interlocking Framework of Executive Orders Five interlocking executive orders are accelerating data center development nationally, but none overrides Arizona’s authority over siting energy, or infrastructure.

Bona Fide Dispute Defeats Violation of Prompt Payment Act

June 15, 2026 — David Adelstein - Florida Construction Legal Updates
Most, if not all, jurisdictions, including the federal government, have what is known as a “Prompt Payment Act.” The objective is to ensure prompt payment. If prompt payment is not made, the Prompt Payment Act provides for interest penalties, as well as potentially other costs such as attorney’s fees. But the thing is, it’s not as simple as untimely payment to support the recourse and interest penalties the applicable Prompt Payment Act affords. And the teeth associated with the applicable Prompt Payment Act are not as sharp as perhaps the party claiming untimely payment prefers. Read the full story...

Nevada’s Mandatory Nonbinding Arbitration Law for Civil Cases is Going Through Changes

May 14, 2026 — Brandon Wright & Manuel Gurule - Lewis Brisbois
Nevada currently operates an expedited litigation program designed to resolve civil disputes with a value up to $50,000 without incurring the “usual” expense of litigating these disputes. Over time, however, the number of civil cases that have been “exempted” from this program based on the claimed damages exceeding $50,000 has grown dramatically. In response, the Nevada Legislature recently enacted a number of rule changes designed to streamline Nevada’s arbitration process and include more cases. Among these changes are increasing the arbitration “cap” from $50,000 to $100,000. By way of background, the Nevada’s Court Annexed Arbitration program is a mandatory, non-binding program for civil cases in judicial districts that have county populations of 100,000 or more [1]. Nevada’s Court Annexed Arbitration was born out of NRS 38.250, which was enacted in 1991 and went into effect in the summer of 1992. The newly enacted NRS 38.250 was regarded as a way to address the problem of increased court caseloads while promoting judicial economy and efficiency in civil cases having a probable jury award of less than $25,000 [2]. Initially, cases that were automatically exempt from the program included class actions, medical malpractice disputes, divorce proceedings, and other domestic relations matters [3].
