The following permits are typically required to install a swimming pool in Wisconsin. Actual requirements vary by municipality.
Swimming Pool Permit
Required for installing in-ground and above-ground swimming pools, hot tubs, and spas in Wisconsin. Wisconsin regulates residential pools under SPS 390 and requires barrier fencing, proper drainage, and electrical safety measures. Public and semi-public pools fall under SPS 390 with additional requirements for filtration, sanitation, and lifeguard provisions.

Fence Permit
Required in most Wisconsin municipalities for installing new fences above a certain height. Requirements vary — some cities require permits for all fences, others only for fences above 6 feet. Setback requirements, material restrictions, and height limits differ by zoning district and municipality.
Electrical Permit

All electrical work on residential dwellings must be performed by a licensed master or journeyman electrician, or by a homeowner on their own single-family residence.

Frequently Asked Questions
Do I need a permit for an above-ground pool in Wisconsin?
In most Wisconsin municipalities, yes — both above-ground and in-ground pools require a permit if the pool holds more than 24 inches of water or has a capacity exceeding 5,000 gallons. Even smaller above-ground pools may trigger fence/barrier requirements. Check your local ordinance for specific thresholds, as they vary by city.
What are the fence requirements for a pool in Wisconsin?
Wisconsin municipalities generally require a barrier fence around all residential swimming pools. The fence must be at least 48 inches tall with a self-closing, self-latching gate. Openings in the fence cannot allow a 4-inch sphere to pass through. For above-ground pools, the pool wall may count as part of the barrier if it meets the height requirement and the ladder is removable or lockable.
How far from the property line does a pool need to be in Wisconsin?
Pool setback requirements vary by municipality but typically range from 5 to 10 feet from side and rear property lines. Some cities require pools to be within the buildable area of the lot (behind the front setback line). Equipment such as pumps and filters may have additional setback requirements due to noise. Check your local zoning code for exact requirements.
