Texas, Comanche County HVAC Permit Regulations and County Ordinances for Unincorporated Areas

Comanche County Building & Safety Jurisdiction

Comanche County does not maintain a centralized, countywide building department that issues general building or mechanical (HVAC) permits for all types of construction. The county's regulatory authority is primarily focused on specific areas, such as subdivision platting and On-Site Sewage Facilities (OSSF/septic systems). If your property is located within the limits of an incorporated city (such as the City of Comanche, De Leon, or Gustine), you must contact that city's building department, as they hold jurisdiction over permits and inspections within their municipal boundaries.

Rules for Properties in Unincorporated Areas

For properties located in the unincorporated areas of Comanche County, there is no documented countywide general building permit requirement for standard residential or commercial HVAC installations. However, property owners should be aware of the following:

Verify Jurisdiction: Always confirm that your property is truly outside of any city limits or Extraterritorial Jurisdiction (ETJ), as cities may enforce their own building codes within these areas.
Specific County Requirements: While a general HVAC permit may not be required by the county, you must still comply with any applicable state laws and regulations. If your project involves new construction or significant modifications that include an On-Site Sewage Facility (OSSF), you are required to file an OSSF application with the county and obtain authorization before beginning work.
State-Level Considerations: Even in the absence of a county permit, all HVAC work in Texas must be performed by a state-licensed HVAC contractor. Additionally, for certain residential projects, you may need to consider state-law overlays, such as private-inspection rules (e.g., Texas HB 2833), which may be required by lenders, insurers, or for future property sales.
Consult Local Officials: Because regulations can change and specific projects may have unique requirements, it is recommended to contact the Comanche County Courthouse directly to verify if any new orders or specific requirements apply to your project.

Texas Hvac Legislation, Codes, and Guidelines

State-Level Building Codes and HVAC Legislation in Texas

Texas does not have a single, mandatory, statewide residential building code that applies to all jurisdictions. Instead, the state grants local municipalities and counties the authority to adopt and enforce their own building codes. While the state legislature has enacted statutes that establish baseline standards for cities that choose to adopt building codes, the specific editions and enforcement levels can vary significantly between different cities and counties.

For HVAC-related work, the primary regulatory framework is established through the Texas Occupations Code, Chapter 1302, which mandates that HVAC contractors and technicians be licensed by the state. While local jurisdictions often adopt the International Mechanical Code (IMC), International Residential Code (IRC), and International Fuel Gas Code (IFGC) as the basis for their local ordinances, these are enforced at the local level rather than by a single state-wide building department.

Primary State Agencies and Boards

Texas Department of Licensing and Regulation (TDLR): This agency is the primary regulatory body for HVAC professionals in Texas. It administers the licensing program for air conditioning and refrigeration contractors, technicians, and apprentices under the authority of the Texas Occupations Code, Chapter 1302. TDLR also oversees the administrative rules found in the Texas Administrative Code, Title 16, Chapter 75, which govern the practice of HVAC work.
State Energy Conservation Office (SECO): SECO is responsible for adopting and maintaining energy efficiency standards for state-funded buildings and provides guidance on energy codes, such as the International Energy Conservation Code (IECC), which impacts HVAC system efficiency requirements.
