Hendersonville's Swimming Pools & Spas: The Rules That Matter

If you live in Hendersonville or are thinking about moving there, swimming pools & spas are one of those things you probably won't think about until they affect you directly. Hendersonville has 4 specific rules on the books covering different aspects of swimming pools & spas, and some of them might surprise you.

Pool Permits

All swimming pools, spas, and hot tubs in Hendersonville require a building permit from the Building & Codes Department (101 Maple Drive North, 615-822-3802, codes@hvilletn.org). The City has adopted the 2021 International Swimming Pool and Spa Code (effective July 1, 2025), the 2021 IRC, 2021 IBC, and 2020 NEC with amendments. The applicant must submit a complete Swimming Pool Plan Submittal package including a scaled site plan, pool depths, property dimensions, easements, mechanical/plumbing/gas details, electric service location, fencing design, drainage, and engineered design for gunite pools and retaining walls.

Key details: Permitting Authority: Hendersonville Building & Codes - 615-822-3802. Permit Required For: All swimming pools, spas, hot tubs (in-ground, above-ground, on-ground). Governing Code: 2021 ISPSC + 2021 IRC/IBC + 2020 NEC (effective 7/1/2025). Prior Code: 2018 ISPSC (through 6/30/2025). Submittal Email: codes@hvilletn.org.

Installing a pool without a permit, submitting an incomplete plan set ('INCOMPLETE SUBMITTALS WILL NOT BE ACCEPTED'), failing to show easements/setbacks, omitting the pool fencing design or gate-swing direction, building a gunite pool without engineered design, or skipping the electrical/plumbing/gas inspections violates Hendersonville's adopted codes. Building & Codes can issue stop-work orders, require demolition of unpermitted work, and assess civil penalties. Lakefront pools that encroach on TVA shoreline easements or undeclared Public Utility Easements may have to be removed at the owner's expense.

This is not one of those rules that cities tend to ignore. Hendersonville actively enforces its pool permits requirements.

Safety Rules

Hendersonville's pool safety rules come from the City-adopted 2021 ISPSC (effective July 1, 2025) plus the 2020 NEC (Article 680) and the City's Swimming Pool Plan Submittal Checklist. Required safety measures include a 48-inch ISPSC Section 305 barrier with self-closing/self-latching gates opening outward, anti-entrapment compliance with the Virginia Graeme Baker Pool and Spa Safety Act, door alarms or powered safety covers where a dwelling wall is part of the barrier, engineered design for gunite pools and any surcharge-bearing retaining walls, and full NEC bonding/grounding (Article 680) inspected separately.

Key details: Governing Codes: 2021 ISPSC + 2020 NEC Article 680 (effective 7/1/2025). Barrier: 48 inches minimum, 4-inch max opening (ISPSC 305). Gates: Self-closing, self-latching, open outward from pool. Anti-Entrapment: VGBA-compliant covers (ANSI/APSP-16) + secondary protection on single-drain pools. Door Alarms: UL 2017 required where dwelling wall is part of barrier.

Failing to maintain an ISPSC-compliant 48-inch barrier with self-closing/self-latching gate is the most-cited violation. Missing VGBA-compliant main-drain covers, single-drain pools without secondary entrapment protection, doors with direct pool access lacking alarms or self-closing devices, GFCI receptacles missing within 20 feet of the pool, missing equipotential bonding, gunite pools built without engineered design, and pool retaining walls without engineering all trigger Building & Codes enforcement. The City may require the pool to be drained or covered until safety violations are corrected.

This is one of the stricter rules in Hendersonville's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Hot Tub Rules

Hot tubs and spas in Hendersonville require a permit from Building & Codes (615-822-3802) under the City-adopted 2021 ISPSC and 2020 NEC. ISPSC barrier requirements (Section 305) apply, but Section 305.5 provides an important exception: a spa or hot tub equipped with a safety cover that complies with ASTM F 1346 is exempt from the 48-inch barrier provisions. Hot tubs also require dedicated 240V GFCI-protected electrical service per NEC Article 680.42, with shut-off disconnects within sight and at least 5 feet from the tub.

Key details: Permit Required: Yes - Building & Codes (615-822-3802), 2021 ISPSC. Barrier Exception: ISPSC 305.5 - ASTM F 1346 safety cover exempts spa/hot tub from Section 305 barrier. GFCI Protection: Required on hot tub branch circuit (NEC 680.43(A)). Disconnect Location: Within sight of spa but at least 5 ft from inside walls (NEC 680.13/680.42(C)). Equipotential Bonding: All metal surfaces within 3 ft must be bonded (NEC 680.26).

Installing a hot tub without a permit violates the City-adopted 2021 ISPSC and may result in a stop-use order from Building & Codes. Missing or non-compliant ASTM F 1346 cover (when used to satisfy the barrier exception), no GFCI on the spa circuit, disconnect not within sight or too close to the spa, missing equipotential bonding, or accessory-use setback violations in SR-1/SR-2 are all enforceable. Hot tubs that drain into the City sanitary or storm system without authorization can additionally violate Title 18 (Water and Sewer).

This is one of the stricter rules in Hendersonville's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Fencing Requirements

Hendersonville pool barriers are governed by Section 305 of the 2021 International Swimming Pool and Spa Code as adopted by the City effective July 1, 2025. Barriers must be at least 48 inches above grade on the side facing away from the pool, openings may not allow a 4-inch sphere to pass, gates must be self-closing, self-latching, and open outward away from the pool, and the latch must be at least 54 inches above the bottom of the gate. The City's Swimming Pool Plan Submittal Checklist independently requires applicants to show 'Pool fencing design and location to show enclosure around pool area' and 'All gates to indicate swing away from pool.'

Key details: Governing Code: 2021 ISPSC Section 305 (City of Hendersonville, effective 7/1/2025). Minimum Barrier Height: 48 inches above grade (305.2.1). Max Ground Clearance: 2 inches on side facing away from pool. Max Opening: 4-inch-diameter sphere may not pass (305.2.2). Vertical Spacing (low horizontal): Max 1-3/4 inches.

Failure to maintain a compliant barrier is the most common pool-code violation. Self-closing gates that have failed, latches below 54 inches not on the pool side, openings over 4 inches, barriers under 48 inches, gates that swing toward the pool, and climbable objects (chairs, ladders, AC units, planters) within reach of the barrier all trigger code-enforcement action. Building & Codes may require the pool to be drained or covered until violations are corrected.

Compared to other cities, Hendersonville takes a harder line on fencing requirements. The enforcement and penalty structure reflects that.
