Pool Construction Permits in Rockford
Local Rule
City of Rockford Community & Economic Development
The city's own page states the threshold directly: any structure over 24 inches deep needs a permit, with a real distinctive tiered structure based on the number of dwelling units served. A private pool serving up to 4 dwelling units needs only a City of Rockford permit, while a pool serving other facilities or more than 4 dwelling units is classified as a public pool and needs BOTH a City permit AND a permit from the Illinois Department of Public Health, with a copy of the state application required before the city will issue its own permit. Required barrier: 48 inches high, with no more than a 2 inch gap at the bottom and 4 inch openings elsewhere.

How This Compares to Winnebago County
Rockford's own rule is shown above (Permit required). Here is the separate rule that applies at the county level, for context:
Winnebago County Regional Planning and Economic Development
The county's own adopted appendix governs the design and construction of any swimming pool, spa, or hot tub on a one or two family lot in unincorporated Winnebago County, defining a barrier broadly as a fence, wall, building wall, or any combination that completely surrounds the pool and obstructs access to it. The City of Rockford, the county seat, applies the same practical threshold within its own limits: any pool over 24 inches deep, whether in ground, above ground, on ground, a hot tub, spa, or fixed wading pool, requires a permit and a barrier at least 48 inches high, with gaps no greater than 2 inches at the bottom and no greater than 4 inches elsewhere in the barrier, and private pools serving up to four dwelling units still need a city-issued permit.
