Summary
A private backyard pool needs no county pool license. Public and semi-public pools (apartment, HOA, hotel, club) must be licensed annually by the Butler County General Health District under Ohio Revised Code Chapter 3749 and OAC 3701-31.
No person shall operate or maintain a public swimming pool, public spa, or special use pool without a license issued by the licensor having jurisdiction.
Full Breakdown
Ohio state law, not a county ordinance, controls pool licensing. ORC 3749.04 makes it unlawful to operate any public swimming pool, public spa, or special use pool without a license from the local licensor. In unincorporated Butler County and most municipalities the licensor is the Butler County General Health District, which reviews plans (per ODH), inspects, and issues the annual license effective through May 31. Individual private residential pools serving one household are not "public" pools and need no county license, though a city or township building permit may still apply.
Violations & Fines
Operating a public pool without a license violates ORC 3749; the licensor may refuse, suspend, or revoke the license and order closure. Health District enforces via Chapter 119 hearings.
