Scope of Products Requiring Proposition 65 Warnings in California Poised to Grow

February 23, 2026 — Brian M. Ledger & Chassen B. Palmer - Gordon Rees Scully Mansukhani
The scope of products to be drawn into the warning requirements under California’s Proposition 65 law may soon be growing. California’s Office of Environmental Health Hazard Assessment (OEHHA) requested information from the public on the reproductive toxicity of p,p’-bisphenol chemicals. OEHHA is the lead agency for the implementation of Proposition 65, formerly known as the Safe Drinking Water and Toxicity Enforcement Act of 1986. OEHHA’s request for information is a step toward regulators classifying all p,p’-bisphenol chemicals as reproductive toxicants under Proposition 65. California’s Proposition 65 Under Proposition 65, businesses are required to post clear and reasonable warnings before individuals are exposed to chemicals listed by the state of California as carcinogens or reproductive toxicants. To date, California has listed approximately 900 chemicals that fall under Proposition 65 regulation. Businesses may be held liable for up to $2,500 per violation per day. Proposition 65 can be enforced by public prosecutors (e.g., the California attorney general or district attorneys) or by private enforcers (known as “bounty hunters”). Reprinted courtesy of Brian M.

Sausage-Making Often Relies on the Good Sense of the Chef Rather than the Recipe

June 23, 2026 — Garret D. Murai - California Construction Law Blog
Even for lawyers, the rules governing litigation can get complex and convoluted. Does something need to be filed? What needs to be filed? When is the deadline for filing? Simple questions with not always with straightforward answers. This was the case in R & J Sheet Metal, Inc. v. W.E. O’Neil Construction Co. of California, 111 Cal.App.5th 878 (2025), which involved sheet metal panels lost when they fell into the Port of Long Beach harbor. Read the full story...

Data Center Construction and the AEC Partner of the Future

April 14, 2026 — Aarni Heiskanen - AEC Business
During my involvement in designing mobile phone production facilities, the speed of design and construction was critical. Any delay could directly translate into lost revenue. That same logic now applies to data centers, though the stakes are much higher. Instead of optimizing physical production lines, we are constructing infrastructure for digital production. The global data center capacity is expected to nearly double by 2030, and with this level of demand, the traditional project-by-project delivery model begins to show its limitations. Data centers are no longer isolated projects in the traditional sense. They are evolving into repeatable, scalable production systems, making them ideal environments for AEC process and business model innovation. Read the full story...

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.
