The Trump administration filed lawsuits Monday against the California cities of Morgan Hill and Petaluma, seeking to block local ordinances that limit natural gas infrastructure in new buildings.
The lawsuits, brought by the U.S. Department of Justice in federal court in Northern California, argue that the cities’ natural gas restrictions violate a 1975 federal law prohibiting state and local regulations on the energy use of products governed by federal standards.
“The natural gas bans not only impose crushing costs on California residents but are also unlawful,” the complaint stated.
Morgan Hill and Petaluma, both located in the San Francisco Bay Area, enacted ordinances starting in 2019 to limit natural gas in new construction as part of broader climate initiatives. Since 2019, dozens of U.S. cities have adopted similar restrictions.
In 2023, a federal appeals court ruled that the city of Berkeley could not enforce its 2019 ban on natural gas infrastructure, saying the measure conflicted with federal law.
Petaluma City Manager Peggy Flynn said the city had no immediate comment. Morgan Hill officials did not respond to a request for comment. California Gov. Gavin Newsom and Attorney General Rob Bonta have not publicly addressed the lawsuit.
In July, Petaluma and Santa Clara County, where Morgan Hill is located, joined separate lawsuits challenging Trump administration funding restrictions related to diversity, equity, and inclusion policies and sanctuary city policies.
