HVAC Permit Requirements in the City and County of Broomfield
The City and County of Broomfield operates as a consolidated city and county government. Because of this unique structure, there is no separate "county-level" jurisdiction for building permits; all building and safety regulations are managed directly by the City and County of Broomfield's Building Division. This division is responsible for issuing permits, conducting plan reviews, and performing inspections for all construction projects within its boundaries to ensure compliance with adopted building and mechanical codes.
Permit Requirements for HVAC Work
In Broomfield, most HVAC work requires a building permit. This includes the installation or replacement of furnaces, air conditioning units, and other mechanical systems. Permits are necessary to ensure that installations meet current safety, energy, and building code standards. Even for straightforward replacements (such as a one-for-one swap of an A/C unit or furnace), a permit is generally required. Homeowners or contractors must submit a permit application to the Building Division, and the work must pass required inspections upon completion.
Rules for Properties in Unincorporated Areas
There are no "unincorporated areas" within the City and County of Broomfield in the traditional sense of being governed by a separate county entity. Because Broomfield is a consolidated city and county, the entire jurisdiction is governed by the same municipal ordinances and building codes. Any property located within the boundaries of the City and County of Broomfield is subject to the permitting requirements and regulations enforced by the Broomfield Building Division.

Building Code Adoption in Colorado
Colorado is a "home rule" state, meaning there is no single, mandatory statewide building code for private residential or commercial construction. Instead, the authority to adopt and enforce building codes, including those governing HVAC systems, is decentralized and rests with individual municipalities and counties. Local jurisdictions adopt specific editions of model codes—such as the International Building Code (IBC), International Residential Code (IRC), and International Mechanical Code (IMC)—and often layer their own local amendments on top of these standards.
State-Level Oversight and Exceptions
While local governments hold primary authority, certain state agencies establish minimum standards for specific types of construction:
- State Buildings Program (SBP): Part of the Office of the State Architect, the SBP is responsible for establishing minimum building codes for all construction by state agencies on state-owned or state lease-purchased properties.
- Division of Housing (DOH): Within the Department of Local Affairs (DOLA), the DOH adopts and enforces statewide building codes for factory-built housing (manufactured and modular homes) and tiny homes.
- Division of Fire Prevention and Control (DFPC): Part of the Colorado Department of Public Safety, this division adopts building codes for the construction of public K-12 schools and health facilities.
- Energy Code Requirements: State law requires local jurisdictions that update any building code to adopt minimum energy efficiency standards, specifically the 2021 International Energy Conservation Code (IECC) and the Colorado Model Electric Ready and Solar Ready Code (for updates between July 1, 2023, and June 30, 2026). Beginning July 1, 2026, jurisdictions must adopt the state's Model Low Energy and Carbon Code.
