Wake County, NC Swimming Pools & Spas: Pool Permits (2026)

North Carolina splits public-pool regulation between the State (which writes the rules at 15A NCAC 18A .2500 under authority of G.S. Chapter 130A, Article 8) and local health departments (which administer permitting, plan review, inspections, and enforcement). Wake County exercises that delegated authority through the Wake County Department of Environmental Services pursuant to the Wake County Regulations Governing Swimming Pools, adopted by the Wake County Board of Human Services on July 23, 2020. The local regulations explicitly state at Section 1 that they "supplement the North Carolina Rules Governing Public Swimming Pools, 15A NCAC 18A .2500, and shall apply to all swimming pools within Wake County."

Public pool track. Under 15A NCAC 18A .2508, a "public swimming pool" is defined by reference to G.S. 130A-280 — broadly, any pool not built in connection with a single-family residence or duplex and whose use is not confined to the family and their private guests. The State rule classifies pools into five types: (1) swimming pools used primarily for swimming, (2) spas designed for recreational and therapeutic use and not drained between users, (3) wading pools designed for children, (4) water recreation attractions (slides, wave pools, lazy rivers, plunge pools), and (5) special purpose and therapy pools. All five types are subject to the public-pool permitting requirements.

The Wake County Regulations Governing Swimming Pools layer additional, more detailed requirements on top of the State rule. Section 3 requires written plan approval from the Director of the Wake County Department of Environmental Services BEFORE any person constructs, installs, extends, or modifies a swimming pool. Plans must include (1) site plan, (2) plan and sectional view dimensions of the pool and the barrier-fenced area, (3) bathhouse, equipment room, and chemical storage room layouts, (4) manufacturer specifications for all treatment equipment, (5) a piping schematic showing pipes, inlets, main drains, skimmers, gutters, vacuum fittings, and all appurtenances, (6) water supply and wastewater disposal specifications including well location, sewer location, and backwash water disposal, (7) a fencing detail, and (8) a lighting schedule if the pool is open for night swimming. The Director approves plans only when they comply with both the Wake County regulations and 15A NCAC 18A .2500.

Section 5 requires a Wake County Swimming Pool Operations Permit for every public pool. The permit is issued only after a Director-conducted inspection finds the facility in compliance with both the Wake County regulations and 15A NCAC 18A .2500. The permit is valid for not more than 12 months. The annual fee, set by County Environmental Services policy and stated on the Public Swimming Pools FAQ, is $300 per pool, wading pool, spa, or sprayground. Seasonal pools (pool ID numbers beginning with 50, 51, 52, or 56) are invoiced in March; year-round pools (heated or indoor, ID numbers 53, 54, 55, or 57) are invoiced in December. Permit inspections are requested beginning April 1 and are scheduled first-come, first-served; seasonal pools must be permitted by the Memorial Day deadline (May 11) with current VGB documentation and a contacted inspector. Re-inspection following a failed initial permit inspection costs $75.

Section 7 imposes operator requirements. The Owner must ensure that the pool has a properly trained Operator capable of running the pool in compliance with the regulations. Operators must hold a current Certified Pool Operator (CPO) certificate from the Pool & Hot Tub Alliance (PHTA) or an equivalent course approved by the Director. In addition, Wake County maintains its own certification — Operators must pass a test administered by the Department, with the County certificate valid for five years. The Operator must perform and record daily disinfectant residual and pH readings at least twice each day of operation, at least six hours apart; record all chemical additions and hyperchlorination events; record daily temperatures of heated pools and spas; and complete the County-provided CPO maintenance checklist daily.

Section 9 sets water quality standards. The pool must be maintained in an alkaline condition with pH between 7.2 and 7.8 at all times. Free chlorine residual must be 1.0-10.0 ppm in swimming pools and 2.0-10.0 ppm in wading pools and spas; combined chlorine must not exceed 0.5 ppm in pools or 0.2 ppm in wading pools and spas; bromine residual, when used, must be 2.0-20.0 ppm. Failure to maintain disinfectant residual is grounds for immediate suspension of the Operations Permit. Presence of algae, no measurable disinfectant, or fecal contamination requires immediate closure and superchlorination per PHTA guidelines (with fecal contamination handled per 15A NCAC 18A .2535(13)).

Section 15 covers safety. Drain covers must be VGB-compliant under ASME/ANSI A112.19.8-2007, with compliance certified in writing by a NC-registered professional engineer or architect. A working pole at least 12 feet long with a body hook, plus a throwing rope with a Coast Guard-approved ring buoy, must be on hand at all times. Pools over 3,000 square feet require two units of lifesaving equipment. Pools without a lifeguard must post "WARNING NO LIFEGUARD ON DUTY" in 4-inch letters. Spas with hydrotherapy jets must have a 15-minute timer switch. Heaters must have thermostatic controls capping pool water at 90°F and spa water at 104°F. Permanent pool-deck emergency telephones are required, with direct dial and physical-address signage.

Residential pool track. Wake County Pool Regs. Sec. 2(e) defines a "Residential Swimming Pool" as "any swimming pool located on private property, the use of which is limited to swimming or bathing by members of his/her family or invited guests," and expressly excludes facilities inside a residence, storable seasonal pools that are taken down at season's end, and covered spas. Section 1 then exempts residential pools from all requirements EXCEPT Section 10 (Pool Fencing). Practically, residential pool builders deal with Wake County Planning, Development and Inspections — not Environmental Services. Wake County's "Install a Swimming Pool or Hot Tub" guidance requires (1) application through the Wake County Permit Portal, (2) a building permit and electrical permit (and gas permit if a gas heater is used) for any pool, hot tub, or spa holding more than 24 inches of water, (3) a site plan, (4) a Residential Swimming Pool Installation and Inspection Affidavit, (5) workers' compensation insurance certificate or exemption form, and (6) a notarized owner-contractor affidavit for projects over $40,000. All residential pools, hot tubs, and spas must be enclosed by a barrier meeting Appendix V of the NC Residential Code. Onsite Water Protection rules require setbacks from septic systems and on-site wells (Wastewater/Septic: 919-856-7434, wastewater@wake.gov; Groundwater/Wells: 919-856-7482, wellwater@wake.gov). Deck-supported hot tubs require engineer-stamped deck plans. Projects in flood hazard areas or exceeding impervious-area limits require an additional watershed review and a $50 fee.

Note on legacy Section 10 fencing rules: Wake County Pool Regs. Sec. 10 applies on its face to all residential pools constructed before July 1, 2008 (4-foot minimum fence height, gate self-closing and self-latching with latch release at least 54 inches above ground, opening under fence not exceeding 4 inches, horizontal/vertical spacing limits, temporary fencing required during construction). For residential pools constructed on or after July 1, 2008, Sec. 10(d) defers to the NC Residential Code (Appendix V) for fencing — which Wake County PDI enforces through the residential building permit and inspection process.
