The state of Texas has adopted the 2024 International Mechanical Code (IMC), 2024 International Fuel Gas Code (IFGC) and the 2024 International Residential Code (IRC) following a rigorous review process by the Texas Department of Licensing and Regulation (TDLR). This decision reflects the state's dedication to maintaining the highest standards of building construction.
“TDLR’s adoption of these 2024 International Codes (I-Codes) is a significant step forward in strengthening public safety, supporting economic growth and ensuring a more resilient and affordable built environment across the state,” said Matt Sigler, PMG executive director, ICC. “By embracing modern, consensus-based codes, Texas is helping communities improve building safety and support the continued growth of industries and infrastructure that drive the state’s success.”
Building codes establish the minimum requirements to ensure safe and resilient structures, and benefits of adoption include cost savings and casualty prevention. The IMC establishes minimum regulations for mechanical systems using prescriptive and performance-related provisions. The IFGC establishes minimum regulations for the installation of fuel gas piping systems and equipment, along with gaseous hydrogen systems. The IRC comprises all building, plumbing, mechanical, fuel gas, energy conservation and electrical requirements for one- and two-family dwellings and townhouses up to three stories. By embracing the 2024 IMC, IFGC and IRC, Texas sets a precedent for other states to evaluate current codes and practices and to adopt updated codes that promote safety, resilience and sustainability in the built environment.
“The State of Texas is currently working under the 2021 IMC adoption," said William Weatherly, chief inspector of air conditioning and refrigeration, TDLR. "Our historical pattern for adoption has been to lag one code cycle behind to allow the Texas HVAC industry to prepare for any significant changes. However, considering the swiftness of the current federal refrigerant mandates now requiring A2L type refrigerants and their new installation and service protocols, that the 2021 mechanical codes do not address; Texas will be adopting the 2024 mechanical codes, including the 2024 IMC."
Building codes serve as a critical foundation for safe, durable and resilient communities. When regularly updated and locally adopted, they protect families, reduce long-term housing costs and improve home performance for decades to come. These standards not only enhance safety but also support affordability by helping homeowners avoid costly repairs and inefficiencies over the life of their homes.
Adoption of the 2024 IMC, IFGC and IRC will go into effect in Texas on Sept. 1, 2026. Read more about the adoption here.
