Full Breakdown
180(A) of the Building Code states that a swimming pool in the ground, on the ground, or in a building shall not be constructed or installed without issuance of a building permit from the city building inspector, and the only carved-out exemption covers storable swimming or wading pools with a maximum wall height of 30 inches that are built to be readily disassembled for storage and reassembled for use, such as a soft-sided kiddie pool. 010, Group IV(f), sets a flat fee of $150 for each permit for a private in-the-ground or above-ground permanent swimming pool, separate from any electrical or plumbing permit fees the installation may also require.
180(C) requires the applicant to show the proposed pool will meet the outdoor pool enclosure standard: a 48-inch barrier with a self-closing, self-latching gate (or the above-ground deck/fence alternative), a 10-foot clearance from electrical wiring, plumbing that complies with the plumbing code, and a footprint no larger than 30% of the rear yard while still meeting accessory-use setbacks. Public swimming pools and private indoor pools instead fall under Wisconsin Administrative Code HSS 171, the state's Public Swimming Places rules, rather than this local permit. 020.
Violations & Fines
Building or installing a pool without the required permit is enforced the same way as any unpermitted construction under the Building Code: it is subject to the general penalty in Section 1.24.010, a forfeiture of $5 to $500 for a first offense and up to $1,000 for repeat violations, with each day of noncompliance a separate offense, and the building inspector can order the work stopped or the pool removed.
