Compliance in San Jose
Santa Clara County projects sit in Climate Zone 4 with some of the state's most aggressive local reach codes. All-electric requirements in several South Bay jurisdictions go beyond what Part 6 alone demands.
What we pay particular attention to on San Jose projects:
- Local all-electric reach codes above state minimum
- Zone 4 heating and cooling balance
- High volume of Eichler-era alteration work
- Dense multifamily and mixed-use development
Climate zone is confirmed by ZIP, not by city name. San Jose projects usually fall in Zone 4, but Santa Clara County is not uniformly one zone and we verify the assignment from your project address before quoting.

San Jose questions
What climate zone is San Jose in?
San Jose projects typically fall in Climate Zone 4. Zones are assigned by ZIP code rather than by city, and Santa Clara 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 Jose?
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 Jose project?
Same-day reports are available from complete plans — tell us the deadline when you send them. Documentation is produced remotely, so San Jose projects run on exactly the same schedule as everywhere else in California. ECC field verification does require a site visit, which we schedule regionally.
