The claim, plainly

In 2019, Berkeley, California became the first U.S. city to pass a municipal ban on natural gas in new buildings.

a quote alone can be ambiguous, so this restates it with the references and context of the conversation around it resolved. AI-written; the tape below the player is the source.

Assessment

In July 2019, the Berkeley City Council formally enacted Ordinance No. 7,672-N.S. ('Prohibition of Natural Gas Infrastructure in New Buildings'), which prohibited fuel gas piping in newly constructed buildings. Contemporary reporting and policy analyses confirmed that Berkeley was the first municipality in the United States to pass such a ban. Although the ordinance was subsequently ruled preempted under federal law by the Ninth Circuit in 2023 and repealed in 2024, the historical statement that Berkeley became the first U.S. city to pass the ban in 2019 is entirely accurate.

On July 23, 2019, the Berkeley City Council enacted Ordinance No. 7,672-N.S., prohibiting natural gas infrastructure in new buildings effective January 1, 2020.
Contemporaneous reporting in July 2019 (by outlets including The Guardian, KQED, and Berkeleyside) and environmental organizations (including NRDC and UCS) verified Berkeley as the first U.S. city to adopt a municipal natural gas prohibition.
