District of Columbia, DC Fence Regulations: Pool Barriers (2026)

DC adopts IRC Appendix G (Swimming Pools, Spas, and Hot Tubs) with District amendments under DCMR 12-A to regulate barriers around private swimming pools, spas, and hot tubs. Any pool capable of holding water more than 24 inches deep must have a barrier at least 48 inches high measured from the finished ground on the exterior side. Vertical openings may not exceed 4 inches; horizontal openings in solid barriers (like stucco walls) are unrestricted, but for picket fences the spacing of horizontal members must not create a climbable condition. Gates serving the pool area must open outward away from the pool, be self-closing and self-latching, with the latch handle located 54 inches or higher above the ground. Where a house wall serves as part of the barrier, doors leading to the pool must have alarms sounding within 7 seconds of opening, or a power-operated safety cover. All permits are issued by the Department of Buildings, and final inspection includes the barrier. Above-ground pools with walls 48 inches or higher may serve as their own barrier if ladders are removable or lockable. DC Public pools additionally fall under DC Health regulations.
