Wayne County, MI Swimming Pools & Spas: Safety Rules (2026)

Michigan adopts the IRC residential pool barrier provisions through the Michigan Residential Code, administered by LARA's Bureau of Construction Codes under Public Act 230 of 1972. The barrier requirements (commonly cited from Appendix G/AG105) apply to any private swimming pool, spa, or hot tub capable of containing water more than 24 inches deep. The barrier must be at least 48 inches above grade measured on the outside of the barrier, the gap between the bottom of the barrier and grade must not exceed 2 inches on the side away from the pool, and openings in the barrier must not allow passage of a 4-inch sphere. Vertical members must be spaced not more than 1.75 inches apart. All pedestrian gates must be self-closing and self-latching, must open outward away from the pool, and the latch must be at least 54 inches above grade or, if lower, located on the pool side of the gate at least 3 inches below the top with no openings larger than 0.5 inch within 18 inches of the release. Where a wall of the dwelling forms part of the barrier, doors leading to the pool area must be equipped with an audible alarm or the pool must have an ASTM F1346 safety cover. Wayne County's role is limited to unincorporated parcels and to soil erosion permits where the pool excavation disturbs more than one acre; the building permit, plan review, and final barrier inspection come from the host municipality's building department. Confirm fence height, gate hardware, and inspection requirements with your city or township and with Wayne County Building & Safety at 734-595-6504 if you are in an unincorporated area.
