Texas, Castro County HVAC Permit Regulations and County Ordinances for Unincorporated Areas
Castro County Building and Safety Divisions
Castro County does not operate a centralized county-level building or mechanical inspection department. There is no general county-wide building permit program for HVAC installations in unincorporated areas. Regulatory oversight in the county is primarily limited to specific state-mandated areas, such as floodplain management and on-site sewage facility (septic) permitting.
Rules for Properties in Unincorporated Areas
In unincorporated areas of Castro County, there are no standard county-level mechanical or HVAC permits required for residential or commercial HVAC work. However, property owners and contractors must still adhere to state-level requirements:
- State Licensing: All individuals performing HVAC installation, repair, or maintenance must be licensed by the Texas Department of Licensing and Regulation (TDLR).
- State Codes: While the county may not enforce local permits, all HVAC work in Texas is subject to state-adopted mechanical and energy codes.
- Other Regulations: If an HVAC project involves other regulated activities—such as new construction that impacts floodplain zones or electrical upgrades that may require utility-level inspections—those specific requirements must be met. Always contact the Castro County Judge’s Office to confirm if your specific project requires any local authorization before beginning 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.
