Basement Finishing Estimating Softwarefor Irvine Contractors
If you're bidding basement finishing in Irvine, the gap between a job that nets margin and one that doesn't usually comes down to forgetting moisture barrier materials — and how you handle wildfire risk in wui zones.

Stuff Irvine basement contractors ask before they sign up
Does this respect CA code, or do I have to re-cut every quantity?
Counts assume CRC + Title 24 Part 6 (Class A roof in WUI, solar PV mandate on new construction, R-15 wall continuous insulation). CA doesn't license basement finishing at the state level, so the variability comes from local amendments. Quantities are correct; you adjust crew rates and local permit assumptions in the bid summary.
How do you handle working around existing utilities and columns?
The model reads the plan once, counts symbols against your assembly library, and surfaces the count for review. You override anything that looks off before it hits the quote. For tech work in Irvine, the typical correction is one or two assemblies — not redoing the whole thing.
What about wildfire risk in wui zones?
Class A fire rating required in many areas. Tile and metal popular for fire resistance. Cool roofs required in many climate zones. Solar panels now mandated on new construction.
How much does a permit add to a basement finishing job around here?
Plan on $350–$9,000 in Irvine, with review running 5–12 weeks. Build that into general conditions so a slow plan-check doesn't eat your overhead. Insurance and bond are separate carrying costs.
