Welcome to the City of Houston’s Construction Code Modernization project page! We encourage all stakeholders to participate as we prepare for the adoption of the 2021 Building Codes.

Construction codes significantly mitigate the effects of hurricanes, storm surges, and extreme weather changes. By staying current with our building codes, we can help our residents protect their homes and businesses by providing safer, more resilient construction that will support greater economic security and public safety.

There are several ways to contribute to the Construction Code Modernization project. Sign up for the newsletter, join a committee, or submit a code amendment.

The Houston Public Works mandate for this code adoption is to adopt the 2021 Code Editions as a base code with local amendments that:

  • Help strengthen and ensure long-term sustainability and resiliency in Houston,
  • Do not reduce the fire- or life-safety provisions without providing an equivalency to what’s found in the base code, and
  • Comply with the intent of the code in quality, strength, effectiveness, fire resistance, durability, and safety for the purpose intended.
