Bay Area board delays water-heater standard to January 2028

The Bay Area Air District board amended its residential water-heater rule on November 4, moving a zero-nitrogen-oxides compliance date from January 2027 to January 2028, the district said.

The district says the standard applies when an existing water heater is replaced; it does not require removal of a working appliance.

Exemption categories include low-income property owners and properties where space or electrical limitations make a switch difficult, the district said. Its summary sets a later January 1, 2033 compliance date for heaters in multifamily properties and deed-restricted affordable housing.

Canary Media’s Alison F. Takemura reported on November 12 that 15 of the 17 board members present supported the amended rule and one abstained. She reported that motions to delay further action and hold a repeal vote had failed before the amendment vote.

At the meeting, a Pacifica property owner raised concerns about paying for upgrades while keeping rents low, Canary reported. The outlet also described opposition from some industry and property-owner groups.
