About Building Codes

Texas statutes, administrative rules, and local ordinances sometimes adopt a specific version of a building or technical code.

This page lists some Texas laws that adopt commonly used building codes like the International Residential Code or the International Building Code. 

Where can I read the codes?

Usually on the publisher's website. These codes are published by independent organizations like the International Code Council and the National Fire Protection Association.

Your local government's website might also have a copy of the version used in their area.

Even though they are incorporated as law, building codes are not reprinted within the law itself. Instead, they are "adopted by reference."

This means that the law will name the code and its publisher, but you must access the code itself elsewhere.

How do I find the code I need for my project?

Requirements in your city or county may be different than the version adopted by state law.

In many cases, state law allows local officials to adopt a more recent edition of a statewide building code.

Ask your local building or code enforcement department for help determining which codes are relevant to your specific project.
