Permit Requirements for Westcliffe, Colorado
For HVAC projects in Westcliffe, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Custer 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.

Custer County Building and Safety Jurisdiction
Custer County does not have a traditional county-wide building department that enforces a comprehensive building code for all construction. Instead, the county operates primarily through its Planning and Zoning Office, which focuses on land use, zoning compliance, and specific permit requirements for structures. Because the county has not adopted a general building code, it does not issue standard HVAC permits for mechanical work.
Rules for Properties in Unincorporated Areas
For properties in unincorporated Custer County, the following rules apply regarding HVAC-related work:
- State-Level Requirements: While the county does not issue HVAC permits, construction involving electrical or plumbing components—which are often integral to HVAC systems—is governed by the State of Colorado. You must obtain the necessary electrical and plumbing permits directly from the State of Colorado.
- Zoning Permits: A zoning permit is required for most structures before excavation or construction begins. This process ensures compliance with zoning resolutions, such as setbacks and height requirements, rather than mechanical or building code standards.
- Compliance Inspections: Upon completion of a project, a compliance inspection may be required to verify that the structure, including any installed plumbing or electrical systems, meets the county's zoning commitments and that state-required inspections for those trades have been completed.
- Consultation Recommended: Because regulations and permit requirements can change, and because HVAC work often involves safety-critical systems (gas, electrical, and refrigerant), it is essential to contact the Custer County Planning and Zoning Office directly before starting any project to confirm the current requirements for your specific situation.

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.
