Coryell County Building and Safety Jurisdiction

Coryell County does not operate a general building department that issues permits for ordinary residential or commercial building construction, including HVAC installations, in unincorporated areas.

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.
