Bathroom Remodeling Estimating Softwarefor Chicago Contractors
If you're bidding bathroom remodeling in Chicago, 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 tornado and severe thunderstorm risk. Drop a plan set in, walk away for 12 minutes, come back to a priced bid you can defend.
What Chicago does to a bathroom remodeling bid
Extreme temperature swings, cold winters, hot summers, tornado risk. Temperatures swing 0°F - 95°F, rainfall runs 30-40 inches, and inspectors here are working off IRC R301.2 / IECC Zone 5. 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 Chicago bathroom remodelers ask before they sign up
Does this respect IL code, or do I have to re-cut every quantity?
Counts assume IRC R301.2 / IECC Zone 5 (frost depth 42 in., Class 4 impact-resistant shingles on most insurers, R-49 attic). IL doesn't license bathroom remodeling 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 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 commercial work in Chicago, the typical correction is one or two assemblies — not redoing the whole thing.
What about tornado and severe thunderstorm risk?
Impact-resistant shingles recommended for hail. Class 4 rated materials reduce insurance costs. Hip roofs better in high winds than gables.
Anything else specific to Illinois?
