Texas follows a local adoption model, meaning that building code adoption and enforcement occur at the municipal level. While certain codes are listed in Texas state statute, individual cities, counties, and municipalities may adopt their own building codes and amendments.

However, effective July 1, 2024, all industrialized housing and buildings, modules, and modular components must comply with the state-mandated codes, as amended in 70.101 of the IHB Rules. For more detailed information regarding local code adoption and amendments, it is necessary to consult with local jurisdictions directly.
