Wausau, WI Building Safety: Building Permits (2026)

Before any footing or foundation excavation, or before construction, alteration, remodeling, or moving of a building or structure, Wausau Municipal Code Section 15.20.010 requires a building permit signed by the City's Building Inspector. The permit can be secured by the property owner, the contractor, or the party actually performing the work, and the code allows prosecution of any of them for proceeding without one. Permit fees are billed at the rate the Common Council sets in Section 3.40.010(a) and are payable to the City Treasurer.

Section 15.20.020 adds that no building permit issues for a new building or structure until the Building Inspector approves plans and specifications, including a plot plan showing the building's location relative to property lines and enough detail to show the exact construction to be performed. For commercial work, Section 15.20.025 has Wausau operating as a Delegated Agent Municipality under Wisconsin Administrative Code SPS 361.60 and SPS 382, so the City's own certified commercial building inspectors handle plan examination and inspection for new commercial buildings, additions, and alterations to fire alarm, sprinkler, plumbing, or HVAC systems, rather than routing those plans to the state.

Section 15.20.040 places further conditions on permits (though not on a private garage or accessory building): the abutting street grade must already be approved by the Common Council, or be at a grade the City Engineering Department finds acceptable, and water and sewer mains must already reach the abutting street or be programmed for installation the following year. Even after those conditions are met, the City withholds the occupancy permit until the building is actually connected to the sewer and water main and the City has inspected and approved those connections.
