Summary
Madison's Building Code lets homeowners skip the 48-inch fence otherwise required around a private swimming pool when the pool is an aboveground portable unit. Sec. 29.27(2), MGO, allows the enclosure to be omitted for portable pools, but requires any pool ladder to be removable when the pool isn't in use.
(2)Portable Pools. The enclosure may be omitted where portable pools are installed aboveground. Where pool ladders are provided, they shall be a type that can be removed when pool is not in use.
Full Breakdown
Sec. 27, MGO, governs private swimming pools in two subsections. ' Subsection (2), 'Portable Pools,' carves out an exception for aboveground units: 'The enclosure may be omitted where portable pools are installed aboveground. ' In practice this means a homeowner who buys a standard aboveground/portable pool does not need to build the 48-inch perimeter fence an in-ground pool owner must build, but any ladder that lets someone climb in from outside must be removable, the code's substitute safety measure for the fence it waives. The section was repealed and recreated by ORD-21-00024 on March 26, 2021, and sits inside Chapter 29, the Building Code, so it is enforced by the Building Inspection Division of the Department of Planning and Community and Economic Development rather than by the Zoning Administrator. A portable pool sited near a rear or lakefront lot line is still subject to the separate zoning setback table at Sec. '
Violations & Fines
A portable pool installed without a removable ladder, or one whose owner leaves a fixed access ladder in place while the pool is unattended, violates Sec. 29.27(2) as part of Chapter 29's Building Code. Sec. 29.20(2), MGO, sets the penalty for any Chapter 29 violation at a forfeiture of $10 to $1,000, with each day of continued violation a separate offense.
