Every Chicagoland renovation involves at least one permitting authority — and most involve two or three (municipal, HOA, and potentially historic-district review). This region-by-region guide walks through real 2026 fees, timelines, inspection sequence, common mistakes, and exactly what we handle on your behalf. Based on 500+ permitted Chicagoland projects across three distinct jurisdictions.
