The San Francisco Board of Supervisors on Tuesday approved an ordinance that requires commercial buildings over 50,000 square feet to begin relying on electricity generated from renewable sources.
The legislation, introduced by Mayor London Breed, was passed by unanimous vote and amends existing environment code for all non-residential buildings. The ordinance requires the city’s largest buildings, more than 500,000 square feet, to rely fully on renewable electricity by 2022. In 2024, buildings larger than 50,000 square feet will have to start converting to renewable electricity. The goal is to have all those buildings using renewable electricity by 2030.
The ordinance comes after Berkeley became the first city in the nation in July to ban the installation of natural gas lines in new homes. But San Francisco’s measure is different, focusing on existing and new commercial buildings and not banning gas. Breed’s office called it the first such ordinance of its kind in the country. If the mayor signs it, as expected, it will go into effect in 30 days.
