The building codes are listed in Texas state statute; however, building code adoption in Texas takes place at the local level. To obtain more detailed information on local building code adoption and amendments, please contact local jurisdictions directly.
Texas is a home rule state. Building code adoption takes place at the local level. However, Texas’ municipal building, residential, fire, plumbing, mechanical, fuel gas and swimming pool and spa codes are promulgated through legislation and found in state statute.
A Listing of these codes is referenced at Texas State Law Library at https://www.sll.texas.gov/law-legislation/texas/building-codes/. Municipalities can make local amendments to these respective codes as well as adopt later editions of them at will. To obtain more detailed information on local building code adoption and amendments, contact local municipalities in Texas directly.
Section 214.212 of the Local Government Code adopts the International Code Council’s International Residential Code as it existed on May 1, 2012, as the municipal residential code for the state.
This law also allows a municipality to adopt local amendments to the code and to review and adopt any amendments made after May 1, 2012, by the International Code Council.
For the correct version of the code for your municipality, please contact your local government officials.
In larger cities, you can usually find this information on the city website. Otherwise you may need to contact your municipality in person or by phone. Each municipality is different so this could be a planning department, a code enforcement department, or some other permitting office.
Section 214.211 “Residential” means having the character of a detached one-family or two-family dwelling or a multiple single-family dwelling that is not more than three stories high with separate means of egress, including the accessory structures of the dwelling, and that does not have the character of a facility used for the accommodation of transient guests or a structure in which medical, rehabilitative, or assisted living services are provided in connection with the occupancy of the structure.
The energy conservation code is promulgated through the Texas State Energy Conservation Office (SECO) by administrative rule. A municipality or county may establish procedures to adopt local amendments to Texas’ commercial and residential energy codes. However, such amendments may not result in less stringent energy efficiency requirements in non-attainment and affected counties. To obtain more detailed information on commercial and residential energy codes adopted in Texas, contact SECO. See https://comptroller.texas.gov/programs/seco/code/adoption.php.
