Swimming Pools & Spas in Madison, WI

Madison maintains 144 local ordinances across all categories, and 2 of those deal specifically with swimming pools & spas. Here is a breakdown of what the city actually requires, what is prohibited, and where Madison falls on the strict-to-permissive spectrum compared to other cities.

Fencing & Safety Requirements

Madison requires every public swimming pool to hold a Public Swimming Pool license before opening, issued jointly by Public Health Madison and Dane County under Sec. 7.44, MGO. The section adopts Wis. Admin. Code chs. SPS 390 and ATCP 76 by reference as the minimum safety and sanitation standards a licensed pool must meet.

Key details: License required: Public Swimming Pool license. Issuing authority: Public Health Madison and Dane County. Application deadline: 7 days before opening. License year: July 1 - June 30. Late renewal fee: 25% of license fee.

Operating a public pool without a license, or in violation of Sec. 7.44 or the adopted SPS 390/ATCP 76 standards, draws a forfeiture of $10 to $100 per offense under Sec. 7.44(9)(a), with each day a separate offense, plus a fee for operating unlicensed and possible suspension or revocation of the license by Public Health Madison and Dane County.

Pool Permits

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.

Key details: Enclosure requirement: Waived for aboveground portable pools. Ladder rule: Must be removable when not in use. In-ground comparison: 48-in. fence required, Sec. 29.27(1). Enforcing agency: Building Inspection Division. Penalty: $10-$1,000 forfeiture per day.

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.

Madison is more permissive than most cities when it comes to pool permits. That said, there are still limits.

The Bottom Line

Madison's swimming pools & spas rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Madison is broadly strict or permissive.
