California’s Commercial Tenant Protection Act (SB-1103) took effect on January 1, 2025. Conceived as a transparency and displacement prevention measure for small businesses, the new law creates tenant protections for small enterprises and nonprofits leasing commercial property that resemble those more typically found in residential leases. A tenant who self-attests that it is a “Qualified Commercial Tenant” (“QCT”) within the meaning of SB-1103 may receive longer notice periods for rent increases and lease terminations, as well as new rights and remedies with respect to passthroughs of operational costs. Under certain circumstances, the law also requires landlords to provide translations for

On Monday, June 30, 2025, Governor Gavin Newsom signed into law two bills, AB 130 and SB 131, which provide new exemptions from, and streamlines the process, under the California Environmental Quality Act (CEQA). AB 130 creates a statutory exemption for qualifying infill housing projects, streamlines the CEQA review process for residential projects in the coastal zone, and provides procedural changes to the administrative review process to prevent unnecessary delays for new development projects. SB 131 focuses on accelerating public interest projects, such as clean water infrastructure, park and trail projects, and community support facility projects, by creating new exemption

On June 16, 2025, the San Diego City Council voted 5-4 to cap the number of Accessory Dwelling Units (ADUs) that can be built on single-family lots. The decision reverses the City’s 2020 implementation of a program allowing developers to build a nearly unlimited number of ADUs—a robust incentive previously heralded as a solution to the City’s burgeoning housing affordability crisis. This program rollback reflects local jurisdictions struggles in addressing the lack of affordable housing supply and meeting Housing Element requirements while facing stark community opposition to high-density development.

A Federal District Court in California has ruled that Proposition 65 warning requirements for dietary acrylamide are unconstitutional. The California Chamber of Commerce (“CalChamber”) sued five years ago challenging the statewide requirement under Proposition 65 for warning labels on foods containing acrylamide. (California Chamber of Commerce v. Bonta, No. 2:19-cv-02019-DJC-JDP.) This ruling is a major victory for CalChamber and the latest chapter in its long battle with the California Attorney General and private enforcer Council for Education and Research on Toxics (“CERT”) over whether a warning can be required by the State in light of the disputed science around acrylamide.

The U.S. Environmental Protection Agency (EPA) announced a comprehensive set of actions to address per- and polyfluoroalkyl substances (PFAS) contamination on April 28, 2025, with a focus on preventing PFAS from entering drinking water systems, holding polluters accountable, and protecting passive receivers. According to EPA Administrator Lee Zeldin, this announcement represents the initial phase of a strategy aimed at tackling PFAS contamination throughout the Trump Administration. Despite the announcement’s emphasis on enforcement, significant questions remain regarding the EPA’s commitment to existing core PFAS regulation.

Until this year, food companies—often the target of Proposition 65 enforcement actions—have been limited to specific “full-length” language for Prop 65 warnings, without explicit guidance regarding whether short-form warnings could be used as a safe harbor warning for food products and non-alcoholic beverages. Prior to the implementation of amended regulations this year, Prop 65 regulations required the following full-length warnings for food products containing a listed carcinogen or reproductive toxicant:

The United States Fish and Wildlife Service and the National Marine Fisheries Service (collectively, Services) proposed last week to rescind the regulatory definition of “harm” under the federal Endangered Species Act (ESA), sparking intense criticism from environmental advocacy groups. If finalized, the rescission would remove a longstanding protection for the habitat of wildlife species listed as threatened or endangered under the ESA, making regulatory compliance easier for many types of projects across the country. But it would also set up a potential collision between the current president’s deregulation efforts and one of several bills that California’s Legislature is considering as
