Home service pros in O'Fallon, IL
9 companies based in O'Fallon and 24 more whose own websites say they serve it.
Housing. O'Fallon is in St. Clair County. U.S. Census Bureau estimates (American Community Survey, 2019–2023) put the median year built for its 13,152 housing units at 1995; about 27% were built before 1980 and 40% in 2000 or later (Census table B25034).
- A large share of homes went up after 2000, so many owners are now meeting their first round of furnace, AC, water heater and roof replacements. Check your subdivision's covenants or HOA rules before exterior work.
- Metro East summers are hot and humid and winters bring freeze-thaw cycles, so furnace and AC tune-ups, gutter cleaning and roof checks before each season pay off.
Permits. Inside city limits, permits are handled by the City of O'Fallon Building & Inspections Division (618-624-4500 ext. 4). The city lists the 2021 International Building Code as in effect from January 1, 2026, and requires an occupancy permit when a home changes owners or tenants and no current permit is on file. Rules change, so confirm with the office before work starts.
