Texas, De Witt County HVAC Permit Regulations and County Ordinances for Unincorporated Areas
De Witt County Building and Safety Jurisdiction
De Witt County, Texas, does not operate a general countywide building department or a city-style general building permit program for unincorporated areas. The county's regulatory oversight is limited to specific, narrow programs rather than comprehensive building code enforcement.
Rules for Properties in Unincorporated Areas
For properties located in the unincorporated areas of De Witt County, there is no verified requirement for a general HVAC permit. County-level permit controls are restricted to the following specific areas:
- On-site sewage facility (OSSF/septic) permits.
- Floodplain development permits.
- Driveway access permits.
- Oil and gas/right-of-way permits (including pipeline permits).
If your property is located within an incorporated city, you must contact that city's building department, as they maintain their own permitting authority and requirements for HVAC and other construction work.

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.
