Summary
A backyard pool at a single-family home needs only a municipal building permit under the PA Uniform Construction Code. A public or semi-public pool (HOA, club, apartment, motel) additionally needs a state Public Bathing Place Permit and a Certificate of Registration from the Chester County Health Department.
A person may not operate a public bathing place without a Certificate of Registration issued by the Department. The Certificate of Registration covers all pools, including wading, diving, racing, water slides, hot tubs, etc. that are operated at a particular site.
Full Breakdown
Chester County is one of only about ten Pennsylvania counties with its own health department, so it directly regulates public pools. Under Chester County Health Department Rules §602.2, a public bathing place needs three things: a construction permit from the local municipality (PA Uniform Construction Code), a Commonwealth Public Bathing Place Permit, and a county Certificate of Registration covering all pools, wading pools, water slides, and hot tubs at the site. Private single-family residential pools used only by the owner are excluded. Registrations expire April 30 and renew annually.
Violations & Fines
Operating a public bathing place without a valid Certificate of Registration is prohibited; the Health Department may suspend or revoke registration and order the pool closed.
