Compliance in Los Angeles
Los Angeles projects span coastal Climate Zone 6 and inland Zone 9 within a single city boundary, and the zone assigned to your address changes the compliance margin materially. LADBS also has its own submittal expectations on top of the state requirements.
What we pay particular attention to on Los Angeles projects:
- Zone 6 vs Zone 9 assignment changes envelope and HVAC trade-offs
- LADBS submittal formatting and registration expectations
- Heavy ADU and garage-conversion volume under city ordinances
- Extensive alteration and tenant-improvement work in older stock
Climate zone is confirmed by ZIP, not by city name. Los Angeles projects usually fall in Zone 6 and 9, but Los Angeles County is not uniformly one zone and we verify the assignment from your project address before quoting.

Los Angeles questions
What climate zone is Los Angeles in?
Los Angeles projects typically fall in Climate Zone 6 and 9. Zones are assigned by ZIP code rather than by city, and Los Angeles 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 Los Angeles?
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 Los Angeles project?
Same-day reports are available from complete plans — tell us the deadline when you send them. Documentation is produced remotely, so Los Angeles projects run on exactly the same schedule as everywhere else in California. ECC field verification does require a site visit, which we schedule regionally.
