The amendment packages above do not contain the unamended portions in the model code. The model codes can be purchased through the respective publishers at, or

The proposed amendments were developed by Building Code Enforcement staff with the goal of minimizing the number of amendments to maintain the code as close as possible to the nationally promulgated codes ensuring the City of Houston stays current with the codes adopted throughout the country. Each amendment was justified as to its impact and necessity. Historical amendments that were not necessary were removed, such as pointers, clarifications or reworded code language with the same intent.

Interested persons are invited to submit proposals for code change amendments in writing. The code change proposal form is available by clicking on the respective Code Change Proposal Form above. Proposed amendments need to be justified with an explanation indicating whether it increases safety, maintains a reasonable level of safety in a cost effective manner, or addresses unique local conditions. The Plumbing Code, Mechanical Code and Electrical Code Change Proposal comment period is closed.  The Building Code Change Proposal form must be submitted by January 14, 2015 and the Residential Code Change Proposal form must be submitted by February 1, 2015 in order to be reviewed for inclusion in the updated code amendments.
