County Building & Safety Divisions and Jurisdiction
The Montgomery County Building Inspections Department is responsible for issuing permits and inspecting work related to building trades, including HVAC systems. They enforce the North Carolina State Building Code and the North Carolina Fire Prevention Code.
This department serves both the unincorporated areas of Montgomery County and the municipalities within the county, including Star, Biscoe, Candor, Troy, and Mt. Gilead.

Additionally, zoning permits are required prior to the construction of any structure or the commencement of any use of an existing building or land in the unincorporated areas of Montgomery County. The Montgomery County Planning Department enforces its zoning ordinance specifically in these unincorporated areas.
Specific Requirements for HVAC Permits
- Site Plan: For residential properties, a properly marked site plan is required if outdoor heating/cooling equipment and tanks are being installed or relocated, in accordance with Montgomery County Zoning Ordinance setback requirements.
- ACCA Manual J Calculations: For residential properties, ACCA Manual J Calculations (Eighth edition) are mandatory if ductwork is being installed or added to an existing or new system.

Applications will not be processed without the submission of the required Manual J calculation.

North Carolina HVAC Building Codes and Legislation
In North Carolina, HVAC systems are regulated under the North Carolina State Building Code. Rather than adopting the International Codes (I-Codes) in their entirety, the state adopts specific volumes of the I-Codes and modifies them with North Carolina-specific amendments to suit local needs, climate, and construction practices. As of early 2026, the 2018 North Carolina State Building Code remains in effect, with the 2024 edition scheduled to become effective on July 1, 2025.
The primary volumes governing HVAC installations include:
- North Carolina Mechanical Code: Governs the design, installation, and maintenance of mechanical systems, including heating, cooling, and ventilation.
- North Carolina Residential Code: Contains specific provisions for HVAC systems in one- and two-family dwellings.
- North Carolina Energy Conservation Code: Sets mandatory energy efficiency standards for HVAC equipment, ductwork, and insulation.
- North Carolina Fuel Gas Code: Regulates the installation of fuel gas piping and appliances often associated with HVAC systems.
Primary State Agencies and Boards
The administration and development of these codes are managed by the following entities:
- North Carolina Building Code Council (BCC): This body is responsible for the adoption, amendment, and maintenance of the North Carolina State Building Code. It conducts public hearings and follows a formal rulemaking process to update code requirements.
- North Carolina Office of State Fire Marshal (OSFM): Operating under the Department of Insurance, the OSFM provides administrative support to the Building Code Council. Its Engineering and Building Codes Division is responsible for the interpretation and enforcement oversight of the state building codes.
- Local Inspections Departments: While the state sets the standards, the actual enforcement of these codes—including plan review and field inspections for HVAC installations—is carried out by local government inspections departments as required by North Carolina General Statutes.
