Eau Claire County HVAC Permit Requirements
In Eau Claire County, Wisconsin, HVAC permit requirements are primarily handled at the municipal level. However, for properties located in unincorporated areas, Eau Claire County's Land Use Division oversees building permits, which would include HVAC work. It is crucial to first determine which jurisdiction your property falls under, as cities and villages within the county have their own permitting processes. You can use the county's Permitting Authority Lookup Tool to identify the correct authority for your address. If your property is in an unincorporated area and requires a permit, you will need to apply through the county's InspectWIZ system, submitting a Property Address Application, site plan, and potentially a Land Use Permit, along with building plans. Sanitary permits may also be required from the Health Department.
Generally, permits are required for the installation, replacement, or significant modification of HVAC systems, including furnaces, boilers, air conditioners, heat pumps, and ductwork. Routine maintenance, such as filter changes or cleaning, does not require a permit. For new HVAC system installations or modifications to existing ductwork, a mechanical permit is necessary. Replacing an HVAC unit with a like-for-like system also typically requires a mechanical permit.
Wisconsin adheres to the Uniform Dwelling Code (UDC) for residential buildings and commercial codes for other structures. The City of Eau Claire, for instance, utilizes an online permitting system (Evolve Public portal) and requires permits for installing or replacing furnaces, wood-burning stoves, fireplaces, central air conditioning units, or making alterations to the distribution or fuel supply system.
For properties in unincorporated areas, the Eau Claire County Land Use Division is responsible for building permits. This includes HVAC work. The process involves verifying your property's jurisdiction, applying online through InspectWIZ, submitting necessary documents like site plans and building plans, and obtaining any required sanitary permits. For properties within a city or village, you must contact that specific municipality for their HVAC 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.
