Do I Need a Permit to Install a Swimming Pool in Wisconsin?

Swimming pool permits are required in most Wisconsin municipalities for both in-ground and above-ground pools that hold more than 24 inches of water or exceed 5,000 gallons in capacity. The permit process covers the pool structure, required barrier fencing, electrical connections for pumps and filters, and in some cities, stormwater drainage from the pool area. All residential swimming pools in Wisconsin must have a barrier fence at least 48 inches tall with a self-closing, self-latching gate. The gate must open outward (away from the pool). Fence openings cannot allow passage of a 4-inch sphere. For above-ground pools, the pool wall may serve as part of the barrier if it meets the height requirement, but the access point (ladder or steps) must be removable or lockable. These safety requirements apply regardless of whether the municipality requires a separate fence permit. Pool permits typically cost $100 to $750 depending on the municipality. You will also need an electrical permit ($50–$200) for the pump, filter, heater, and lighting connections — all pool electrical equipment must be bonded and grounded per NEC requirements. Setback requirements for pools vary by city but typically require 5 to 10 feet from property lines and must be within the buildable area of the lot. Some municipalities restrict pool equipment placement due to noise concerns.
