Rock Hill, SC Swimming Pools & Spas: Pool Permits (2026)

Rock Hill layers two permit tracks for residential pools, plus a state-level permit for public / semi-public pools. (1) Zoning permit: Chapter 31 governs pool location - typical SC city pattern is that pools must be placed in the side or rear yard (not the front yard), setback at least some minimum distance from each lot line, and decks adjacent to the pool also setback. Confirm the exact setback for your zoning district with the Planning and Development Department. (2) Building permit (Residential Code): South Carolina building codes are adopted statewide by the SC Building Codes Council under S.C. Code Ann. § 6-9-50, requiring every municipality to enforce the latest adopted editions. The current adopted residential code is the 2021 South Carolina Residential Code (IRC 2021), effective January 1, 2023, and the ISPSC is also adopted. The IRC / ISPSC apply to any pool over 24 inches deep. The building permit covers structural design (dead-man anchors for aboveground walls, hydrostatic relief for in-ground vinyl liners), electrical (NEC Article 680 - equipotential bonding, GFCI protection, no overhead conductors within 22.5 feet of water), plumbing (anti-entrapment drain covers per the federal Virginia Graeme Baker Pool and Spa Safety Act, 15 U.S.C. § 8003), and the barrier and access controls (IRC Appendix G / Chapter 42 and ISPSC § 305). Required submittals typically include a site plan showing setbacks, manufacturer specifications or stamped engineering drawings for the pool shell, electrical-service plan, equipment locations, and a barrier plan. Hot tubs and spas under 24 inches deep are typically exempt from the pool-shell permit but still require electrical permits for the heater and pump. (3) Public / semi-public pools: S.C. Code Ann. § 44-55-2310 et seq. (the State Recreational Waters Act) and S.C. Reg. 61-51 (Public Swimming Pools) require an annual operating permit from SCDES (formerly DHEC) for any pool not confined to a single-family residence - apartment-complex pools, HOA pools, hotel pools, and gym pools all qualify. The state permit covers water-chemistry, lifeguard coverage (by pool type and patron count), and emergency-equipment standards.
