Do I need a permit for swimming pool or spa in Unincorporated DuPage County?
Yes. In Illinois, swimming pool or spa generally requires a permit, and Unincorporated DuPage 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 DuPage County, permits outside the cities are handled by the DuPage County Building and Zoning Department, reachable on 630-407-6700 at https://www.dupagecounty.gov/government/departments/building_and_zoning/building_and_permits/. This office permits the unincorporated parts of DuPage 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.
