County-Level Jurisdiction and Unincorporated Areas
Winnebago County's Planning & Zoning Department handles planning, zoning, and subdivision services for properties in the unincorporated areas of the county. This includes monitoring and regulating public health, land use, private sewage systems, construction, and erosion control. For properties within village or municipal limits, the respective local government provides these services.
For unincorporated areas, a zoning permit is required before commencing activities such as establishing a new use of property, excavating, building, or altering any structure. The County Zoning Department issues permits for zoning, sanitary, stormwater, erosion control, and temporary uses. It's important to note that the County Zoning Department issues zoning permits, not building permits.
If your property is located in a shoreland area, additional zoning permits may be required for fill, patios, or sidewalks/driveways within 75 feet of the Ordinary High Water Mark.
Specific HVAC Permit Information
While the search results do not detail specific HVAC permit requirements for Winnebago County, it is noted that HVAC installations require mechanical and electrical permits. In Wisconsin, an HVAC permit may not be issued until an electrical permit is obtained from a master electrician, with exceptions for distribution-only permits. Homeowners may not perform their own installation of air conditioning units.
For commercial properties, if HVAC work requires state-level plan review, the HVAC permit and approved plans must be submitted. The State of Wisconsin adheres to the Wisconsin Uniform Building Code for all HVAC work.
It is advisable to check with the County Zoning Office and the Town Building Inspector regarding permit requirements, as any external additions or alterations to a structure typically require a zoning permit.

- Commercial and Multi-Family Buildings: These are governed by the Wisconsin Commercial Building Code, found in Chapters SPS 361–366 of the Wisconsin Administrative Code. Chapter SPS 364 specifically addresses heating, ventilating, and air conditioning (HVAC) systems by adopting the International Mechanical Code (IMC) with Wisconsin-specific modifications.
- One- and Two-Family Dwellings: These are regulated under the Wisconsin Uniform Dwelling Code (UDC), found in Chapters SPS 320–325. HVAC requirements for these dwellings are specifically detailed in Chapter SPS 323.
Primary State Agencies
The primary agency responsible for the development, adoption, and oversight of building, fire safety, and energy efficiency codes in Wisconsin is the Department of Safety and Professional Services (DSPS). Within the DSPS, the Division of Industry Services (DIS) manages the programs for commercial buildings and one- and two-family dwellings, coordinating with local certified municipalities that handle plan reviews and inspections.
