Do I need a permit for swimming pool or spa in Unincorporated Cook County?
Yes. In Illinois, swimming pool or spa generally requires a permit, and Unincorporated Cook County is no exception.
In-ground and permanent above-ground pools require a permit in most Illinois jurisdictions. The often-quoted exemption for prefabricated pools less than 24 inches deep comes from the model residential code, not from Illinois law, so confirm the depth and pool type your jurisdiction actually exempts. Most local codes mandate a compliant safety barrier and electrical bonding before the pool can be used. In Cook County, permits outside the cities are handled by the Cook County Department of Building and Zoning, reachable on 312-603-0500 at https://www.cookcountyil.gov/agency/building-and-zoning. Its online permit portal is https://bzpermits.cookcountyil.gov/permit-status/. This office permits the unincorporated parts of Cook County. If your address sits inside a municipality, that municipality issues the permit instead. A pool involves a building permit, a separate electrical permit for bonding, and a barrier inspection before final sign-off.
