Summary
County code requires any residential pool barrier to stand at least 48 inches tall and its gates to close and latch themselves automatically, keeping young children from wandering in unsupervised.
The top of the barrier shall be at least 48 inches (1219 mm) above grade measured on the side of the barrier which faces away from the swimming pool... Access gates shall comply with the requirements of Items 1 through 7, and shall be equipped to accommodate a locking device. Pedestrian access gates shall open outward away from the pool, and shall be self-closing and have a self-latching device.
Full Breakdown
Chapter 17.46.020 sets the physical fence standard for pools, spas and hot tubs in unincorporated Sangamon County: the barrier's top must be at least 48 inches above grade, with no more than a 2-inch gap at the bottom on the side facing away from the pool. Any access gate must meet those same barrier standards, take a locking device, and -- for pedestrian gates -- open away from the pool with a self-closing, self-latching mechanism. Mesh, picket spacing and diagonal-lattice openings are separately capped to keep a 4-inch sphere from passing through. The rule sits in the zoning code, so it governs only outside Springfield, Chatham and the county's other incorporated towns.
Violations & Fines
A pool fence under 48 inches, a gate that doesn't self-close and self-latch, or openings wider than the code allows violates § 17.46.020 and can draw a zoning enforcement order.
