While the state provides baseline codes and oversight, local municipalities and counties are typically responsible for issuing building permits and enforcing state codes. For HVAC work, this often involves obtaining permits from the relevant local authority, which could be the county or a specific municipality within the county.

A building permit is generally required for new construction, additions, remodels, and modifications to systems like HVAC. For unincorporated areas, the Oneida County Planning and Zoning Department is the primary point of contact for permits related to land use and development.

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.

- 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.
