Texas, Dallam County HVAC Permit Regulations and County Ordinances for Unincorporated Areas
HVAC Permit Requirements in Dallam County, Texas
Dallam County does not operate a countywide building department or a general building permit program for residential or commercial construction. Consequently, there is no county-level mechanical or HVAC permit requirement for properties located in unincorporated areas of the county.
While the county does not issue general building permits, property owners and contractors must still comply with state-level regulations. In Texas, HVAC work is governed by the Texas Department of Licensing and Regulation (TDLR). Contractors performing HVAC work must hold a valid Air Conditioning and Refrigeration Contractor (ACRC) license issued by the state. Additionally, all HVAC installations and replacements must adhere to the state-adopted mechanical and energy codes, regardless of whether a local permit is required.
If your property is located within the city limits or the extraterritorial jurisdiction (ETJ) of a municipality like Dalhart or Texline, you must contact that city's building or development services department, as they may have their own specific permit requirements and inspection processes.
Even in the absence of a county permit, it is recommended that property owners ensure all HVAC work is performed by a licensed professional to maintain safety, protect manufacturer warranties, and ensure compliance with state energy efficiency standards.

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.
