Since January 1, 2026, permits are reviewed under California's 2025 Building Energy Efficiency Standards. The Energy Commission says these standards apply to additions and alterations as well as new buildings, but not to repairs, and that this cycle leans toward heat pumps for space and water heating.
- Replacing HVAC is its own question. Ask the Building Division which energy documents and field checks apply to the new equipment. This page does not require a named rater.
- Ask about energy paperwork. Confirm with the Building Division whether a Title 24 report is required for the interior work. This page does not name a form number.
- Ask about appliance rules. Confirm with the City whether a rule for new buildings or substantial rebuilds applies to the appliances in your scope. This page does not apply a percentage test.
