California, Tehama County HVAC Permit Regulations and County Ordinances for Unincorporated Areas
Tehama County HVAC Permit Requirements
In Tehama County, California, installing or replacing an HVAC system generally requires mechanical and electrical permits to ensure compliance with current energy and safety codes. The permitting process is considered relatively streamlined.
County Jurisdiction and Unincorporated Areas
The Tehama County Department of Building & Safety is responsible for issuing permits and conducting inspections for construction projects, including those in unincorporated areas. While the City of Tehama contracts with the county for these services, the county retains responsibility for permitting and inspections for construction-related permits.
Permit Application Process
To obtain a permit, you will typically need to submit an application along with a plot plan approved by relevant agencies (Planning, Building, Environmental Health, County Fire, and Public Works). Depending on the project, additional documents may be required, such as:
- Complete sets of building plans
- Energy calculations
- Truss calculations
- Modified soils test (for Single Family Residences)
- Structural calculations (if applicable)
- Solar plans and Manual J Report
- Flood Elevation Certificate (if applicable)
- Written evidence that lien holders have released interest in a manufactured home (if applicable)
After plan check completion, you may need to pay fees to the Air Pollution Control District. Permit fees are then paid before receiving approved plans.
Specific Requirements for Mobile Homes
Mobile homes manufactured after January 21, 2009, must meet Chapter 7A of the CBC for Wildland Urban Interface and State Response Area requirements. If this applies, a permit from HCD (Housing and Community Development) is necessary, and a copy of the final approval must be provided to the Building Department.

California HVAC Building Codes and Legislation
California does not adopt the International Residential Code (IRC) or International Building Code (IBC) in their entirety as the primary basis for its HVAC regulations. Instead, the state maintains its own comprehensive set of standards known as the California Building Standards Code, which is found in Title 24 of the California Code of Regulations. HVAC systems in California are primarily governed by the following components of Title 24:
- Part 6: The California Energy Code (Building Energy Efficiency Standards): This is the most critical section for HVAC systems. It sets mandatory requirements for equipment efficiency, duct sealing and insulation, system sizing (often requiring adherence to ACCA Manual J and Manual D), and thermostat controls. These standards are updated on a three-year cycle to increase energy efficiency and promote the transition to technologies like electric heat pumps.
- Part 4: The California Mechanical Code (CMC): This code provides the technical requirements for the design, installation, and maintenance of mechanical systems, including heating, ventilation, and air conditioning, to ensure safety and proper operation.
- Part 11: The California Green Building Standards Code (CALGreen): This code includes provisions for indoor air quality, ventilation, and sustainable building practices that complement the energy efficiency requirements.
Primary State Agencies
The regulation and development of these standards are managed by key state entities:
- California Energy Commission (CEC): The CEC is responsible for developing and updating the Building Energy Efficiency Standards (Title 24, Part 6). They focus on reducing energy consumption and setting efficiency benchmarks for HVAC equipment and installation practices.
- California Building Standards Commission (CBSC): The CBSC is the agency responsible for the overall administration, publication, and adoption of the California Building Standards Code (Title 24) as a whole.
