Heat Pumps in Oakland: Rules, Permits and Rebates

Air District rules, permits and incentives.

Updated October 28, 2026

What the Air District rules say

Rules 9-4 and 9-6 are point-of-sale standards for newly installed furnaces and water heaters. Each date applies to appliances made on or after it:

• January 1, 2027: zero-NOx standard for water heaters under 75,000 Btu per hour, which covers most home tank units
• January 1, 2029: zero-NOx standard for residential and commercial furnaces
• January 1, 2031: zero-NOx standard for larger water heaters, from 75,000 Btu per hour up to 2 million

The Air District says a gas appliance that can show it meets the standard would be allowed. A heat pump burns no gas at the house, so it meets a zero-NOx standard by design.

Oakland and all-electric construction

In December 2020 the City Council adopted an ordinance requiring newly constructed buildings to be all-electric. The City now says it has been legally directed to suspend that requirement. The ordinance covered new construction, so it never set rules for what goes into an existing house.

Permits and inspections

The City of Oakland requires a building permit to add, change or fix mechanical and electrical systems, and some eligible projects can get a same-day digital permit. A heat pump swap may need electrical work too if the panel or circuit changes. Depending on the job, the state energy code may require HERS testing. The Energy Commission advises homeowners to request the finished HERS paperwork from whoever did the work.

Rebates and incentives

Incentive amounts change too often to print here. Start with these programs:

• TECH Clean California, a statewide program funded in part by the Greenhouse Gas Reduction Fund, whose heat pump incentives are paid out to enrolled contractors
• California Energy-Smart Homes, administered by PG&E, which offers rebates for electrifying space and water heating
• The Switch Is On incentive finder, which lists current programs for Oakland addresses, income-qualified offers included
• Alameda Municipal Power, for homes in Alameda, which has run its own heat pump rebates

Ask each contractor which programs they are enrolled in, since TECH Clean California incentives only come through participating contractors.

Questions about Heat pump rules and rebates in Oakland

Do I have to replace my gas furnace by 2029?

No. The 2029 date is a standard for new furnaces, tied to when they are made. It governs what gets sold and installed, not when a working furnace has to come out.

Will a heat pump keep an Oakland house warm?

With January lows averaging around 45 degrees, Oakland winters are easy work for a heat pump. Sizing and duct condition matter more than the weather here.

Can I keep my gas water heater?

Yes, until it needs replacing. Home water heaters under 75,000 Btu per hour made from January 1, 2027 on must meet the zero-NOx standard.
