Section 214.216 of the Local Government Code adopts the International Code Council's International Building Code as it existed on May 1, 2012, as the municipal commercial building 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.
