- Installing a new HVAC system requires a mechanical permit. Estimated fees range from $200 to $750, with a typical timeline of about two weeks.
- Modifying or installing new ductwork also requires a mechanical permit. Estimated fees range from $100 to $400, with a typical timeline of about two weeks.
- Work done without the required permits may result in double permit fees.
Jurisdiction and Unincorporated Areas
While the City of Racine has its own Building Inspection Department, Racine County's Public Works and Development Services department handles zoning and land use matters, including for unincorporated areas. For properties in unincorporated areas of Racine County, the Development Services office, located at the Ives Grove Office Complex, is the point of contact for zoning and land use inquiries. They can be reached at (262) 886-8440 or [email protected]. If you suspect a zoning violation in an unincorporated area or the Village of Yorkville, you should contact Racine County Development Services.
It's important to note that specific requirements can vary, and it is always recommended to contact the relevant building department or the Racine County Development Services office directly to confirm the exact permit needs for your project.

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.
