Northwest Suburbs Remodel Permits: Arlington Heights, Schaumburg, Palatine
Northwest Suburbs permitting is the most efficient of any Chicagoland region — most municipalities maintain online application systems, plan review averages 3-7 business days for standard remodels, and inspector availability is generally good. The complications here are usually HOA overlays (most subdivisions built after 1985 have HOAs that require approval on top of municipal permits) and stormwater detention requirements for larger decks and patios. This guide is based on our 180+ NW Suburbs permitted projects.
Cities covered: Arlington Heights, Palatine, Schaumburg, Hoffman Estates, Rolling Meadows, Mount Prospect, Des Plaines, Wheeling, Buffalo Grove, Barrington, Park Ridge, Glenview, Skokie

- Working without contractor license on file with municipality
- Closing walls before inspection passes — must reopen at homeowner expense
- Wrong egress window dimension for basement bedroom
- Missing AFCI on bedroom circuits — fails electrical rough
- Wrong tempered-glass spec near tubs/showers — fails final
- Not posting permit card visibly on home exterior — inspectors will leave without inspecting
