Why Illinois pricing looks the way it does
Illinois pricing varies hugely between Chicago metro and the rest of the state.
- Chicago union labor. Cook County and the collar counties have strong union presence with trade rates of $40–$58/hr. Downstate (Peoria, Springfield, Champaign) drops to $24–$36/hr.
- Chicago permit complexity. City of Chicago permits average $400–$1,000 with a 4–8 week plan review. Suburban municipalities are simpler ($200–$500) and faster (1–3 weeks).
- Pre-1940 housing in Chicago neighborhoods. Lincoln Park, Logan Square, Hyde Park, and similar pre-war neighborhoods regularly trigger galvanized supply line replacement, knob-and-tube remediation, and lead-paint protocols.
