Permit Requirements for Carrizo Springs, Texas
For HVAC projects in Carrizo Springs, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Dimmit County.
Authority Having Jurisdiction (AHJ)
Most jurisdictions require permits for HVAC work to ensure safety and code compliance. The governing body responsible for issuing these permits varies by specific location:
General HVAC Guidelines
Permits are usually required for new installations, structural modifications, or major repairs. While minor maintenance or cosmetic updates may be exempt, landowners should always verify local codes before work begins.

Because Carrizo Springs is located within Dimmit County, the following broader county regulations may also apply to your project:

Dimmit County Building & Safety Jurisdiction
Dimmit County does not operate a centralized, county-wide building and safety department that issues general mechanical or HVAC permits for all construction projects. Unlike many incorporated cities in Texas, the county's regulatory oversight is limited to specific areas, such as floodplain management, on-site sewage facility (OSSF/septic) permitting, and burn-ban restrictions. Because there is no county-level mechanical inspection program, there is no standard county permit process for HVAC installations or replacements in unincorporated areas.
Rules for Properties in Unincorporated Areas
For properties located in the unincorporated areas of Dimmit County (outside the city limits of Asherton, Big Wells, and Carrizo Springs), the following considerations apply regarding HVAC work:
- Lack of Local Enforcement: Because the county does not have a general building permit program, there is typically no local authority to issue an HVAC permit or perform mechanical inspections for standard residential or commercial HVAC work.
- State-Level Licensing: While a local permit may not be required by the county, all HVAC work in Texas must be performed by a contractor holding a valid Air Conditioning and Refrigeration Contractor (ACRC) license issued by the Texas Department of Licensing and Regulation (TDLR).
- Due Diligence: Property owners should verify if their specific project requires any other county-level approvals, such as floodplain development permits if the property is in a mapped floodplain, or OSSF permits if the HVAC work involves changes to the property's utility infrastructure.
- Incorporated Areas: If your property is located within the city limits of Asherton, Big Wells, or Carrizo Springs, you must contact those specific municipal offices, as they may have their own adopted building codes and permit requirements for mechanical 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.
