How Sioux Falls Handles Swimming Pools & Spas: A Practical Guide

Sioux Falls maintains 189 local ordinances across all categories, and 5 of those deal specifically with swimming pools & spas. Here is a breakdown of what the city actually requires, what is prohibited, and where Sioux Falls falls on the strict-to-permissive spectrum compared to other cities.

Hot Tub Rules

Hot tubs and non-swim spas in Sioux Falls fall under the 2021 ISPSC but benefit from a meaningful exception: under ISPSC § 305.6, a hot tub or spa equipped with a lockable safety cover that complies with ASTM F1346 is exempt from the perimeter barrier requirement that would otherwise apply to swimming pools. A building permit is still required for installation if the unit is hard-plumbed or hard-wired (most are), an electrical permit and inspection are required for the 240-volt circuit, and NEC Article 680 bonding still applies. A swim spa or active spa designed to allow swimming is NOT eligible for this exception and is regulated as a full swimming pool.

Key details: Perimeter fence required: No — if lockable ASTM F1346 cover is installed. Cover standard: ASTM F1346 (safety cover for spas and hot tubs). Electrical permit: Required for hardwired 240V install; GFCI mandatory. Bonding: NEC 680 Part IV — equipotential bonding required. Disconnect distance: ≥ 5 feet from spa (line-of-sight rule).

Leaving the cover unlocked or absent when the spa is unattended, especially in a home with children, can be cited as a public-safety violation if a complaint is filed. Hardwiring a spa without an electrical permit and inspection is a code violation. Reclassifying a swim spa as a hot tub to avoid barrier requirements is a misrepresentation that voids the permit and subjects the homeowner to permit-after-the-fact fees and required barrier installation.

If you are coming from a city with tighter rules, you will find Sioux Falls gives residents more flexibility on hot tub rules.

Pool Permits

Sioux Falls requires a building permit issued by Planning & Development Services before constructing, installing, or substantially altering any residential swimming pool, spa, or swim spa capable of holding water more than 24 inches deep. The city has formally adopted the 2021 International Swimming Pool and Spa Code (ISPSC), effective January 1, 2022, which governs design, construction, alteration, repair, and maintenance city-wide. A separate electrical permit is required for pool bonding/grounding work, and a fence permit (typically $20) is required for the perimeter barrier. Permit applications must include a site plan showing setbacks, the barrier location, and proximity to overhead power lines.

Key details: Adopted code: 2021 International Swimming Pool and Spa Code (ISPSC), effective Jan 1, 2022. Permit required: Yes — building permit + separate electrical permit + fence permit. Fence permit fee: Approximately $20 (per city Planning & Development Services). Issuing office: Sioux Falls Planning & Development Services, 231 N Dakota Ave. State law on private pools: No statewide barrier statute — SDCL 34-18A covers public bathing places only.

Installing a pool or swim spa without a building permit, beginning excavation before plan review, or activating pool electrical equipment without inspection can result in stop-work orders, mandatory permit-after-the-fact fees, and corrective-construction orders from Building Services. Continuing work after a stop-work order is a municipal misdemeanor under the city's general penalty provisions for code violations.

Safety Rules

Beyond the perimeter barrier, the 2021 ISPSC as adopted by Sioux Falls imposes life-safety requirements that include NEC-compliant electrical bonding and grounding (Article 680), Virginia Graeme Baker Pool and Spa Safety Act anti-entrapment drain covers, suction-outlet protection on single-drain pools, and either door alarms or an ASTM F1346 powered safety cover when the house wall serves as part of the barrier. A separate electrical permit is required for all pool wiring, and a final electrical inspection must be passed before the pool may be filled and energized. South Dakota has no separate state pool-safety statute for private residences — SDCL 34-18A applies only to public bathing places.

Key details: Electrical code: NEC Article 680 (bonding, GFCI, equipotential grid). Drain covers: Must comply with VGB Act / ANSI/APSP-16. Single-drain pools: Require SVRS or other secondary anti-entrapment device. Door alarm spec: UL 2017 audible, 7-second activation, 15-second deactivation. Powered cover spec: ASTM F1346 compliant.

Failing inspection, missing GFCI protection, non-listed drain covers, or absent door alarms result in failed inspections, denial of the certificate of occupancy / pool operation, and required correction at the homeowner's expense. Energizing pool equipment without final electrical inspection is a code violation subject to municipal abatement and fines.

Fencing Requirements

Every residential pool, spa, or swim spa in Sioux Falls capable of holding water 24 inches or deeper must be enclosed by a barrier at least 48 inches tall measured from the exterior grade. Openings in the barrier must not allow passage of a 4-inch sphere, the barrier must withstand a 220-pound horizontal load, and any pedestrian gate must be self-closing and self-latching with the release mechanism at least 54 inches above the ground (or on the pool side of the gate). These requirements come from Section 305 of the 2021 ISPSC, which Sioux Falls has adopted by reference. There is no state-level alternative — SDCL 34-18A governs public pools only.

Key details: Minimum barrier height: 48 inches (measured from exterior grade). Maximum opening size: Cannot pass a 4-inch sphere. Load resistance: Withstand 220 lb horizontal force. Gate hardware: Self-closing + self-latching, opens away from pool. Latch release height: ≥ 54 inches above grade (or interior-side mounted).

Operating a pool without a code-compliant barrier is treated as a continuing building-code violation. Building Services may issue a notice of violation, require draining the pool until the barrier is corrected, and assess civil penalties under the general penalty section of the Sioux Falls Revised Ordinances. Repeat or willful non-compliance after notice can be referred for misdemeanor prosecution under the city's code-enforcement provisions.

Above-Ground Pools

Above-ground residential pools in Sioux Falls follow the same 2021 ISPSC requirements as in-ground pools, but with one important practical advantage: under ISPSC § 305.2.10, where an above-ground pool wall is at least 48 inches high, the wall itself may serve as the required barrier. Any ladder or steps providing access must be either removable when the pool is unattended (and stored to prevent re-installation by a child), or surrounded by a secondary barrier meeting all the standard 48-inch / 4-inch / self-closing / self-latching rules. A building permit is still required, the pool must be set back from property lines per zoning, and electrical bonding of the pool shell, ladder, and pump motor must comply with NEC Article 680.

Key details: Wall-as-barrier height: ≥ 48 inches qualifies (ISPSC § 305.2.10). Ladder rule: Removable + stowed OR surrounded by barrier. Permit required: Yes — building + electrical. Deck guardrail trigger: Decks > 30 inches above grade. Setbacks: Per Title 153 zoning district (typically rear-yard accessory rules).

Leaving a ladder in place when the pool is unattended, or attaching a deck without permits or barrier compliance, are continuing code violations. Inspectors may require the pool be drained until ladder and barrier compliance is achieved. Failure to obtain the original building permit results in permit-after-the-fact fees and possible removal orders if the pool is in a setback area.

The Bottom Line

Sioux Falls's swimming pools & spas rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Sioux Falls is broadly strict or permissive.

Keep in mind that Sioux Falls can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
