Repeat Home Builder Code Change Notice

Effective April 1, 2022, the City of Houston will begin to review residential projects under the 2015 International Residential Code. For Residential Model / Repeat applicants, this will impact all models previously approved under the 2012 International Residential Code.

Per Code Word 2015-B01, there will be some allowances for grandfathering in new site-specific submittals.

Site-specific repeats that fall under the following categories will be permitted to reference 2012 models and are grandfathered under a 2012 site plan review :

  • The site-specific repeat was submitted prior to April 1, 2022.
  • The site is in a location that can provide supporting information to show the intention to develop dated prior to April 1st. This can be submitted under a plat for developments, a wastewater letter, or other verifiable means. This means for developments that have begun the permitting process or have submitted wastewater letters or supplied other means of development information, 2012 models may be used for repeat submittals. However, this is only effective 5 years following the date shown on the submitted verification information.

Please note: You will need to have an updated profile to submit your 2015 model plans under. For example, 2012 MODEL BUILDER ➡️ 2015 MODEL BUILDER”.

To set up the 2015 profile, contact Natoya Perry at [email protected].

In order to best assist and review model submittals in a timely manner, you are encouraged to submit your models for the 2015 IRC review now for any upcoming and new developments. Submitting them prior to the April 1st code change will help your plans move through the system more quickly and efficiently. Your model submittals will be reviewed and approved under the 2015 IRC and ready to use on April 1st. You may not submit for site-specific repeats using the approved 2015 models prior to April 1st.
