Permit Requirements for Burlington, Vermont
For HVAC projects in Burlington, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Chittenden County.
Authority Having Jurisdiction (AHJ)
Most jurisdictions require permits for HVAC work to ensure safety and code compliance. The governing body responsible for issuing these permits varies by specific location:
General HVAC Guidelines
Permits are usually required for new installations, structural modifications, or major repairs. While minor maintenance or cosmetic updates may be exempt, landowners should always verify local codes before work begins.

Chittenden County Building & Safety Jurisdiction
There is no county-level building or safety department in Chittenden County, Vermont. In Vermont, county governments do not have authority over building codes, zoning, or permitting. These responsibilities are handled either by individual municipalities (cities, towns, and villages) or, in areas without local enforcement, by the Vermont Department of Public Safety, Division of Fire Safety.
Rules for Properties in Unincorporated Areas
Vermont does not have "unincorporated areas" in the same sense as many other states; all land in Vermont falls within the jurisdiction of a town, city, or village. However, some municipalities may not have their own local building departments or active enforcement programs. In jurisdictions that do not operate an approved local building enforcement program, the Vermont Division of Fire Safety holds direct jurisdiction. For HVAC work in these areas, you must coordinate directly with the Division of Fire Safety to determine permit requirements, as they are responsible for enforcing state building and mechanical codes where local programs are absent.

Vermont State Building and HVAC Codes
Vermont adopts nationally recognized safety standards, which are amended to address state-specific conditions. As of the 2025 Vermont Fire & Building Safety Code, the state utilizes the 2021 edition of the International Building Code (IBC) as a foundation for commercial and public building safety. HVAC-related requirements are integrated into these broader building and fire safety codes, as well as specific energy standards.
For HVAC systems, compliance is governed by a combination of the Vermont Fire & Building Safety Code and the state's energy standards. This includes adherence to standards such as NFPA 90A (Standard for the Installation of Air-Conditioning and Ventilating Systems) and various mechanical requirements found within the adopted building codes. Additionally, HVAC design and installation must comply with the Vermont Residential Building Energy Standards (RBES) for residential projects and the Vermont Commercial Building Energy Standards (CBES) for commercial and high-rise residential projects, which incorporate efficiency requirements for heating, ventilation, and cooling systems.
Primary State Agencies
The administration and enforcement of these standards are divided between two primary state entities:
- Vermont Department of Public Safety, Division of Fire Safety: This division is responsible for the adoption and enforcement of the Vermont Fire & Building Safety Code, which covers general building construction, fire safety, and mechanical system safety standards.
- Vermont Department of Public Service: This department is responsible for administering and maintaining the Vermont Residential Building Energy Standards (RBES) and the Vermont Commercial Building Energy Standards (CBES), which dictate the energy efficiency requirements for HVAC systems.
