Johnson County administers the Code of Resolutions for Buildings & Construction (2018 Edition) for unincorporated areas. A swimming pool, hot tub, or spa capable of containing more than 24 inches of water requires a building permit from Johnson County Building Codes (913-715-2233). Barriers must include a fence at least 48 inches high with self-closing, self-latching gates that open outward away from the pool. Pools may not be filled with water until a Certificate of Occupancy is issued.
