Compliance in Irvine
Master-planned development at scale in Climate Zone 8, with sophisticated design teams and correspondingly high documentation standards from the city.
What we pay particular attention to on Irvine projects:
- Zone 8 modelling for master-planned communities
- High-rise and mid-rise multifamily compliance
- Extensive commercial and R&D tenant improvements
- Acceptance testing coordination on large projects
Climate zone is confirmed by ZIP, not by city name. Irvine projects usually fall in Zone 8, but Orange County is not uniformly one zone and we verify the assignment from your project address before quoting.

Irvine questions
What climate zone is Irvine in?
Irvine projects typically fall in Climate Zone 8. Zones are assigned by ZIP code rather than by city, and Orange 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 Irvine?
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 Irvine project?
Same-day reports are available from complete plans — tell us the deadline when you send them. Documentation is produced remotely, so Irvine projects run on exactly the same schedule as everywhere else in California. ECC field verification does require a site visit, which we schedule regionally.
