Illinois home permit planning notes
City and village rules dominate many projects. Electrical licensing, frost depth, and zoning placement are common friction points.
What to verify locally
- Whether your property is inside city limits or unincorporated county territory
- Which office handles zoning approval versus building permits
- Whether trade permits must be pulled by licensed contractors
- Whether HOA, historic, coastal, floodplain, wildfire, or utility approval applies
