Florence County HVAC Permit Requirements
Florence County requires permits for major changes to mechanical systems that involve extensions. Generally, any structural changes or significant alterations to mechanical systems necessitate a permit. Restoration or repair to a previous code-compliant condition is typically exempt. The county enforces the Wisconsin Uniform Dwelling Code (UDC) for one- and two-family dwellings and the Wisconsin Commercial Building Code for commercial construction. The Florence County Planning, Zoning & Solid Waste Department is responsible for enforcing these regulations. Permits can be applied for through the county's One Stop portal.
County Building & Safety Divisions and Jurisdiction
Florence County has a Building Inspector who administers and enforces building ordinances, and this inspector must be certified by the Wisconsin Department of Safety and Services. Assistant inspectors must also hold relevant certifications, including for HVAC. The county's enforcement is managed through the withholding of building permits, imposition of forfeitures, and injunctive actions. The county's building and safety jurisdiction extends to municipalities that have adopted a resolution requesting county enforcement and do not have their own UDC enforcement program. Florence County's Planning, Zoning & Solid Waste Department oversees these functions.
Rules for Properties in Unincorporated Areas
The search results indicate that Florence County's building ordinances, including those related to permits, apply within the county. While specific rules for unincorporated areas versus incorporated municipalities are not explicitly detailed, the county's building code adoption and enforcement framework suggests that county-level regulations would apply in areas without their own local enforcement programs. The Town of Florence, for example, directs residents to Florence County Zoning for building and zoning concerns, indicating a county-level jurisdiction for permitting in that town. Therefore, properties in unincorporated areas of Florence County would fall under the county's building permit requirements.

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.
