Building  Electrification

In 2019, 36% of Half Moon Bay’s Greenhouse Gas Emissions were generated from natural gas and propane-powered energy use in buildings. To help curb these emissions, work toward a cleaner environment, and assist the State in reaching SB32 goals, the City adopted a Building Electrification Ordinance on February 15, 2022 that:

  • Requires all new building construction to be electric-only – no gas or propane in new construction
  • Restricts any existing all-electric residential building from adding gas or propane
  • Requires Fuel Gas lines are capped/decommissioned in existing buildings by 2045
