Allentown's Chapter 556 is silent on fencing, so pool barriers are set by the Pennsylvania Uniform Construction Code, which adopts the International Swimming Pool and Spa Code (34 Pa. Code Sec. 403.26(a)): the barrier must be at least 48 inches high, leave no more than 2 inches of ground clearance, block a 4-inch sphere, and pedestrian gates must be self-closing and self-latching.
Allentown does not have a city-specific pool-fence ordinance; residential pool barriers are governed by the Pennsylvania Uniform Construction Code (UCC). Under 34 Pa. Code Sec. 403.26(a), 'A swimming pool, hot tub and spa, which is an accessory to a one-family or two-family dwelling, must comply with the International Swimming Pool and Spa Code of 2021.' The City applies these standards through its Bureau of Building Standards and Safety during plan review under Code Chapter 556 and Chapter 225 (Construction Codes, Uniform). The adopted ISPSC barrier provisions (Section 305.2) require that outdoor pools and spas be surrounded by a barrier where the top is not less than 48 inches above grade, the vertical clearance between grade and the bottom of the barrier does not exceed 2 inches, and openings in the barrier do not allow passage of a 4-inch-diameter sphere. Under Section 305.3, pedestrian access gates must open outward away from the pool, be self-closing, and have a self-latching device; where the latch release is less than 54 inches above grade it must be on the pool side of the gate not less than 3 inches below the top (Section 305.3.3), and utility or service gates not intended for pedestrian use must remain locked when not in use (Section 305.3.1). Above-ground pool walls may serve as the barrier where they meet these dimensions. The Bureau of Building Standards and Safety verifies the barrier through plan review and a required field inspection before a pool is approved for use, which makes the fencing standard strict.
The Bureau of Building Standards and Safety will not pass the required pool inspection or finalize the permit until the barrier height, gate self-latching hardware, and openings are verified. Operating a pool without a compliant barrier is a UCC violation subject to stop-work orders and code enforcement; the city imposes a fine of up to $100 for each type of work done without the required permit.
