Outagamie County HVAC Permit Requirements
Outagamie County, Wisconsin, has specific requirements for HVAC permits, particularly concerning properties in unincorporated areas. The county's Building & Safety Division, or its equivalent, is responsible for issuing these permits. If your property is located within an incorporated city, that city's building department will handle permit applications, not the county.
For properties in unincorporated areas of Outagamie County, the permit authority typically falls under the Outagamie County Development and Land Services, Zoning Administration. It's crucial to verify the specific jurisdiction for your property, as permit requirements can vary.
General HVAC permit requirements in Wisconsin, and thus applicable to Outagamie County, often include:
- Permit Application: A completed application form is necessary. Many counties now utilize online portals for submission.
- Energy Code Compliance: Adherence to the current energy code, such as the 2021 International Energy Conservation Code (IECC), is required. Outagamie County is in Climate Zone 6A, which influences these requirements.
- Required Documentation: This may include, but is not limited to:
- Manual J Load Calculation (recommended for optimal system sizing).
- REScheck Compliance documentation.

- Electrical Permit: In many Wisconsin municipalities, an HVAC permit will not be issued until an electrical permit for the installation has been obtained from a master electrician licensed in the state.

It is important to note that failure to obtain a required permit before starting work can result in penalties, often double the permit fee.

The following statewide building codes and regulations apply universally to all jurisdictions within Wisconsin:
Wisconsin Hvac Legislation, Codes, and Guidelines
State Statutes and Codes Adopted
Wisconsin utilizes a hybrid approach to building codes, maintaining its own administrative code chapters that incorporate and amend national model codes. As of October 1, 2025, Wisconsin transitioned to the 2021 editions of the International Code Council (ICC) suite for commercial and multi-family residential buildings, with specific state-level amendments known as "Wisconsinisms."
- 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.
