Barrier Requirements Electrical Code Raleigh Water
For information on submitting a pool application, visit the Installing a Pool or Spa webpage.
Outdoor swimming pools including in-ground, above-ground, or on-ground pools, hot tubs, and spas, must have a barrier that complies with the following:
- The top of the barrier must be at least 48 inches (1219 mm) above grade, measured on the side of the barrier that faces away from the swimming pool. The maximum vertical clearance between the grade and the bottom of the barrier must be two inches (51 mm), measured on the side of the barrier that faces away from the swimming pool. Where the top of the pool structure is above grade, such as an above-ground pool, the barrier may be at ground level, such as the pool structure, or mounted on top of the pool structure. Where the barrier is mounted on top of the pool structure, the maximum vertical clearance between the top of the pool structure and the bottom of the barrier must be four inches (102 mm).
- Openings in the barrier must not allow passage of a four-inch diameter (102 mm) sphere.
- Solid barriers that do not have openings, such as masonry or stone walls, must not contain indentations or protrusions except for normal construction tolerances and tooled masonry joints.
- Where the barrier is composed of horizontal and vertical members and the distance between the tops of the horizontal members is less than 45 inches (1143 mm), the horizontal members must be located on the swimming pool side of the fence. Spacing between vertical members must not exceed 1.75 inches (44 mm) in width. Where there are decorative cutouts within vertical members, spacing within the cutouts must not exceed 1.75 inches (44 mm) in width.
- Where the barrier is composed of horizontal and vertical members and the distance between the tops of the horizontal members is 45 inches (1143 mm) or more, the spacing between vertical members must not exceed 4 inches (102 mm). Where there are decorative cutouts within vertical members, spacing within the cutouts must not exceed 1.75 inches (44 mm) in width.
- The maximum mesh size for chain link fences must be a 2.25-inch (57 mm) square unless the fence is provided with slats fastened at the top or the bottom that reduce the openings to not more than 1.75 inches (44 mm).
- Where the barrier is composed of diagonal members, such as a lattice fence, the maximum opening formed by the diagonal members must not be more than 1.75 inches (44 mm).
- Access gates must be equipped to accommodate a locking device. Pedestrian access gates must open outward away from the pool and be self-closing and have a self-latching device.
- Gates other than pedestrian access gates must have a self-latching device. Where the release mechanism of the self-latching device is located less than 54 inches (1372 mm) from the bottom of the gate, the release mechanism and openings must comply with the following:
- The release mechanism must be located on the poolside of the gate at least three inches (76 mm) below the top of the gate.
- The gate and barrier must have no opening greater than 0.5 inches (12.7 mm) within 18 inches (457 mm) of the release mechanism.
- Where a wall of a dwelling serves as part of the barrier, one of the following conditions shall be met:
- The pool must be equipped with a powered safety cover in compliance with ASTM F1346; or
- All doors with direct access to the pool through that wall must be equipped with an alarm that produces an audible warning when the door or its screen is opened. The alarm must be listed in accordance with UL 2017. The audible alarm must activate within 7 seconds and sound continuously for a minimum of 30 seconds after the door or its screen is opened and be capable of being heard throughout the house during normal household activities. The alarm must automatically reset under all conditions. The alarm system must be equipped with a manual means, such as a touchpad or switch, to temporarily deactivate the alarm for a single opening. Such deactivation must last for not more than 15 seconds. The deactivation switch must be located at least 54 inches (1372 mm) above the threshold of the door; or
- Other means of protection, such as self-closing doors with self-latching devices, approved by the City of Raleigh are acceptable; providing the above conditions are met.
- Where an above-ground pool structure is used as a barrier or where the barrier is mounted on top of the pool structure and the means of access is a ladder or steps, then:
- The ladder or steps must be surrounded by a barrier that meets the requirements of NCRC Appendix G, Section AG105.2, items 1 through 9. When the ladder or steps are secured, locked, or removed, any opening created shall not allow the passage of a four-inch-diameter (102 mm) sphere.
- Barriers must be located so as to prohibit permanent structures, equipment, or similar objects from being used to climb the barriers.
Barrier exception: Spas or hot tubs with a safety cover that complies with ASTM F 1346 are exempt from barriers.
The following is a quick reference guide for electrical work and does not constitute an all-inclusive list of requirements for swimming pools, spas, and hot tubs. An electrical permit is issued to ensure that all metal parts within five feet of the pool are properly grounded and safe.
