Siding Estimating Softwarefor San Diego Contractors
If you're bidding siding in San Diego, the gap between a job that nets margin and one that doesn't usually comes down to missing gable ends in calculations — and how you handle wildfire risk in wui zones. Drop a plan set in, walk away for 10 minutes, come back to a priced bid you can defend.
What San Diego does to a siding bid
Mild year-round, dry summers, wet winters, fire and earthquake risk. Temperatures swing 45°F - 85°F, rainfall runs 15-25 inches, and inspectors here are working off CRC + Title 24 Part 6. None of that shows up on a plan symbol legend — but it changes your fastener schedule, your waste factor, and whether the building department signs off on the rough.

Stuff San Diego siding 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 siding 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 measuring wall areas minus openings?
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 residential work in San Diego, 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 siding job around here?
Plan on $400–$12,000 in San Diego, with review running 6–14 weeks. Build that into general conditions so a slow plan-check doesn't eat your overhead. Insurance and bond are separate carrying costs.
