An outdoor swimming pool associated with an outdoor amusement or recreation facility must be completely enclosed within a 6-foot barrier under Ada County's zoning code, stricter than the county's general residential pool barrier standard. Ada County's Building Division has issued permits under adopted building codes since 1975 and serves unincorporated areas only, since Boise, Meridian, Eagle, Kuna, Star, and Garden City each administer their own building department. Building permits in Ada County are handled under the Ada County Development Services, Building Division (unincorp building code (IRC Ada County Building ). Local zoning, property-line setbacks, and any electrical or plumbing work can still require separate approval, so confirm the details with Ada County Development Services.
