Colorado, Fremont County HVAC Permit Regulations and County Ordinances for Unincorporated Areas
Fremont County Building & Safety Division and Unincorporated Areas
The Fremont County Building Department is responsible for establishing and enforcing minimum building requirements to ensure safety in the construction of structures within the unincorporated areas of Fremont County. If your property is located within the incorporated limits of cities such as Cañon City, Florence, Williamsburg, Rockvale, Coal Creek, or Brookside, you will need to contact the building department of the respective city.
Fremont County has adopted the 2018 Editions of the International Building Code, the International Residential Code, and the International Energy Conservation Code, as amended by Resolution No. 60, Series of 2020.
The county is transitioning to an online permitting system called Cloudpermit, which will streamline the application and permit process.
For properties in unincorporated areas, permits are generally required for various construction aspects. Structures exceeding 400 square feet necessitate a building permit, as does a septic permit. It is advisable to consult the building department for specific requirements regarding smaller structures like tiny homes or sheds, as these may also have permit needs, especially if they include plumbing or electrical work.
The Building Department is located at 615 Macon Ave., Room 212, Cañon City, CO 81212, and their office hours are Monday through Thursday, 7:00 a.m. to 5:00 p.m.

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.
