Kane County, IL Swimming Pools & Spas: Pool Permits (2026)

Kane County Code section 6-9 adopts, for one- and two-family residences in the unincorporated county, 'Chapter 42 Swimming Pool and Spa Code, 2021 International Residential Code Section 305 - Barrier Requirements as published by the International Code Council,' meaning any residential pool, spa, or hot tub must meet the ICC's barrier standard, primarily the enclosure and gate rules in Section 305, before it can be legally built or filled. A permit application goes through the same process as any other Kane County building permit, administered by the Building & Community Services Division of the county's Development Department.

5, Expiration, specifically lists swimming pools among the project types whose permits expire 180 days after the date of issuance, rather than the standard two-year window for general construction; if the pool is not complete within that window, the owner must obtain an extension or a new permit before continuing work. The county's fee schedule at section 6-12(H) sets a flat permit fee of $300 for an above-ground pool and $600 for an in-ground pool, in addition to any required plan examination fee under section 6-12(G).

8's conformance clause, the site must conform to the county zoning ordinance's own dimensional and setback rules before the pool permit can be issued, and if construction starts before a permit is obtained, section 6-12(P) doubles the applicable fee. Kane County's adoption of the 2021 pool and spa barrier code is separate from any state health-department rules that govern public or semipublic pools; the county's own building code, not a state sanitary code, fixes the private residential permit requirement.
