Title 24 Requirement Checker

A CF1R is the Certificate of Compliance for Title 24 Part 6, the California Energy Code. It documents that your design meets the energy code, and it is submitted with your permit application. You need one whenever the work adds conditioned floor area or alters an energy system, including windows and skylights, heating and cooling equipment, ductwork, water heating, roof insulation, and permanent lighting.

Usually yes. Window and skylight replacement alters the building envelope, so most Bay Area jurisdictions require a CF1R-ALT even for a small count. The report is short and the prescriptive path normally applies, so the fee sits at the low end of the range. Like-for-like repairs and cosmetic work do not trigger it, but your building department makes the final call.

Standard turnaround is 3 to 5 business days, with 1 to 2 business day rush available. To start we need your floor plans and elevations, a window and door schedule or rough sizes, the planned heating, cooling and water heating equipment, insulation values, and the project address. If equipment is not selected yet, we model a compliant assumption and revise the report once you pick the actual units.
