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

Every city handles swimming pools & spas a little differently. In Philadelphia, Pennsylvania, there are 4 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Pool Permits

A Philadelphia building permit is required to install most in-ground and above-ground pools and spas; small prefabricated pools under 24 inches deep and under 5,000 gallons are exempt, and accessory one-family pools can use a no-plans EZ permit if they meet the L&I conditions.

Key details: Issuing agency: Philadelphia Department of Licenses & Inspections (L&I). Permit exempt: Prefab pools/spas under 24 in. deep AND under 5,000 gallons. Above-ground permit fee: $57 (per L&I safety bulletin). Setback: Not within 2 ft of any property line or structure; rear yard only. Separate permits: Electrical and plumbing permits required separately.

Installing a pool or spa that requires a permit without one violates the Philadelphia Building Construction and Occupancy Code. L&I can issue a stop-work order and violation notice, charge investigation/double permit fees, and require the work to be exposed for inspection. The permit cannot be closed out until required inspections, including barrier verification, pass.

Fencing Requirements

Every Philadelphia pool, spa, or hot tub must be restricted by one of three approved barrier options, the standard being a 48-inch-high enclosure with a self-closing, self-latching gate that swings away from the pool.

Key details: Barrier options: 1 of 3 L&I-approved options required for every pool/spa/hot tub. Barrier height: 48 inches. Gate: Self-closing, self-latching, swings away from the pool. Platform guardrail: At least 36 inches high, max 4-inch opening. State authority: PA Swimming Pool and Spa Code 2018 (ISPSC) Section 305.

L&I will not pass the pool's final inspection or close the permit until the required barrier, gate, and (where the house forms part of the barrier) door alarms are verified on site. A pool left unenclosed or with a non-self-latching gate is a code violation subject to L&I notice, fines, and abatement, and an unsecured pool can be cited as a public nuisance.

This is not one of those rules that cities tend to ignore. Philadelphia actively enforces its fencing requirements requirements.

Above-Ground Pools

Above-ground pools in Philadelphia are subject to the same barrier and safety requirements as in-ground pools under §PM-303. Pools with water deeper than 24 inches require a 48-inch barrier. The zoning code does not permit pools in front or side yards, and pools must be at least 2 feet from any property line.

Key details: Barrier: 48 inches if water >24 inches deep. Location: Rear yard only; 2 ft from property line. Code: §PM-303 and Residential Code Appendix G. Permit: Building permit from L&I required. Gate: Self-closing and self-latching.

Unpermitted pools: removal or retroactive permit with double fees. Safety violations: immediate correction required. Fines $100 to $500.

Hot Tub Rules

Hot tubs and spas in Philadelphia must comply with §PM-303 safety requirements. Units with water deeper than 24 inches need a 48-inch barrier with self-closing, self-latching gates. Hot tubs with an ASTM F 1346 compliant safety cover are exempt from the barrier requirement. Electrical work requires an L&I permit.

Key details: Barrier: 48 inches if water >24 inches deep. Exemption: ASTM F 1346 safety cover. Code: §PM-303. Electrical: L&I permit required for wiring. Location: Rear yard per zoning standards.

Unpermitted electrical work: fines and required correction. Drainage violations: remediation required. Safety cover violations: immediate correction.

The Bottom Line

Philadelphia'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 Philadelphia is broadly strict or permissive.
