What changes the price in Illinois
Illinois's climate: cold, windy winters with deep frost and hot, humid summers. These local factors matter most for drywall projects:
- Basements need moisture-resistant board and a small gap above the concrete floor so the drywall doesn't wick water.
- Older homes often have plaster walls. Patching plaster and lath costs more per square foot than drywall, and full replacement adds demolition and disposal.
Labor, sales tax and permits in Illinois
- Labor and prices: Illinois's construction cost index is 1.10 — 10% above the US average, the 9th highest of the 50 states and DC. Prices in big metros (Chicago, Aurora, Naperville) usually run above the state average, and rural areas below it.
- Sales tax: 6.25% state rate plus local taxes (10.25% in Chicago). The estimates on this page don't include it.
- Building rules: Illinois follows local codes — most cities and villages adopt the IRC, while Chicago enforces its own Chicago Building Code. Permits and inspections are handled by your city or county, so confirm requirements with your local building department before you start.
