Compliance in San Francisco
San Francisco's Climate Zone 3 is heating-dominated and cooling-light, which shapes every trade-off in the model. DBI review is exacting, and the city's own green building and electrification ordinances add requirements on top of Part 6.
What we pay particular attention to on San Francisco projects:
- Heating-dominated Zone 3 modelling
- SF green building ordinance and electrification requirements
- Historic-fabric constraints on envelope upgrades
- Dense multifamily and adaptive-reuse projects
Climate zone is confirmed by ZIP, not by city name. San Francisco projects usually fall in Zone 3, but San Francisco County is not uniformly one zone and we verify the assignment from your project address before quoting.

San Francisco questions
What climate zone is San Francisco in?
San Francisco projects typically fall in Climate Zone 3. Zones are assigned by ZIP code rather than by city, and San Francisco County is not uniformly one zone, so we confirm the exact assignment from your project address at intake before quoting. It matters: the zone drives every prescriptive requirement and every performance trade-off in the model.
How much does a Title 24 report cost in San Francisco?
The same as anywhere in California — we do not price by location. ADUs start at $175, single family up to 2,500 square feet at $225, larger custom homes at $325, and additions or alterations at $195. Multifamily and nonresidential are quoted from the drawings. Every price is fixed in writing before we start.
How fast can you deliver a report for a San Francisco project?
Same-day reports are available from complete plans — tell us the deadline when you send them. Documentation is produced remotely, so San Francisco projects run on exactly the same schedule as everywhere else in California. ECC field verification does require a site visit, which we schedule regionally.
