Illinois Home Cost Factors
Modeled state planning factors for U.S. homeowners. These pages use national cost bands multiplied by the state rate-book factor, then add state-specific climate, permit, and housing-stock context. They are not observed contractor invoices.

State-specific planning factors
- Chicago-area trade rates sit above the national typical for electrical and HVAC
- Freeze-thaw cycles drive driveway, stoop, and masonry maintenance
- Older Midwest housing often needs panel upgrades before EV or generator installs
- Basement living commonality increases waterproofing and egress window project demand
- Lake-effect snow belts raise ice-dam and gutter-heating considerations
Pilot state cost pages
Q1 money pages are the first state-level batch. Each link keeps the modeled disclosure visible and uses the same quality gate as future scale batches.

Methodology note
State pages use the national cost record and calculator rate-book multiplier for planning. City pages remain gated until unique local observations or approved modeled disclosures pass review.
