Franklin County HVAC Permit Requirements
In Maine, HVAC installations generally require a permit, reviewed by the local code enforcement officer (CEO) under the Maine Uniform Building and Energy Code (MUBEC). While Franklin County itself issues building permits for properties in its unincorporated areas, incorporated towns within the county will have their own permitting processes.
Unincorporated Areas in Franklin County
For properties in unincorporated areas of Franklin County, the Land Use Planning Commission (LUPC) oversees planning, zoning, and permitting, as there are no local governments. While accessory structures typically do not require permits in these areas, new rules require property owners to notify the state and ensure compliance with standards. Structures exceeding 750 square feet generally require a permit, and specific setback requirements apply, such as 100 feet from lakes or rivers and 15 feet from property lines. Converting an accessory structure into living space also necessitates a permit.
It's important to note that HVAC work in Maine requires licensed professionals. The state has specific licensing requirements through the Maine Fuel Board for various aspects of HVAC work, including oil burner, propane, and natural gas technicians.

Maine HVAC Building Codes and Legislation
The State of Maine regulates building construction, including HVAC systems, through the Maine Uniform Building and Energy Code (MUBEC). As of April 7, 2025, Maine has adopted the 2021 editions of the International Code Council (ICC) model codes. These standards apply to all buildings constructed or renovated in the state, regardless of municipal population, though enforcement requirements vary based on local population size.
The primary codes and standards adopted under MUBEC that govern HVAC design and installation include:
- 2021 International Mechanical Code (IMC)
- 2021 International Energy Conservation Code (IECC)
- 2021 International Residential Code (IRC)
- 2021 International Building Code (IBC)
- 2021 International Existing Building Code (IEBC)
- 2019 ASHRAE 62.1 (Ventilation for Acceptable Indoor Air Quality)
- 2019 ASHRAE 62.2 (Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings) or the CSA-F326-M91 standard
- 2019 ASHRAE 90.1 (Energy Standard for Buildings except Low-Rise Residential Buildings)
Regulatory Agencies and Oversight
The Technical Building Codes and Standards Board is responsible for the creation and maintenance of the MUBEC. Administrative and technical support for the board is provided by the Division of Building Codes and Standards, which is housed within the Maine Office of Community Affairs. While the state sets these standards, enforcement is mandatory in municipalities with a population of 4,000 or more; municipalities with smaller populations may choose whether or not to enforce the code locally, though design compliance with MUBEC standards is generally required statewide.
