Bathroom Remodeling Estimating Softwarefor Los Angeles Contractors
If you're bidding bathroom remodeling in Los Angeles, the gap between a job that nets margin and one that doesn't usually comes down to underestimating tile waste for patterns — and how you handle wildfire risk in wui zones. Drop a plan set in, walk away for 12 minutes, come back to a priced bid you can defend.
What Los Angeles does to a bathroom remodeling 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.

Pulling permits in California: the license you actually need

Subbing under a licensed GC is one workaround, but on direct-to-owner jobs the homeowner can void the contract if you don't hold the card.

Stuff Los Angeles bathroom remodelers 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). The takeoff doesn't pull a permit for you — that's still on whoever holds the B General Building Contractor License (or applicable C-class) — but the assemblies match what CA inspectors look for.
How do you handle tile calculations for walls and floors?
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 Los Angeles, 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.
Anything else specific to California?
Any bathroom remodel over $500 (labor + materials) requires a licensed contractor in California. Water efficiency compliance per California Plumbing Code is mandatory.
How much does a permit add to a bathroom remodeling job around here?
Plan on $600–$18,000 in Los Angeles, with review running 8–20 weeks. Build that into general conditions so a slow plan-check doesn't eat your overhead. Insurance and bond are separate carrying costs — California also requires a $25,000 contractor's bond.
