The 2012 Phoenix Building Construction Code became effective July 1, 2013.

Building codes are published to meet the needs of local jurisdictions charged with enforcement of building standards for construction and use, and are updated to reflect the latest standards of life-safety and construction technology. The amendments to the 2012 building codes were adopted by City Council on May 15, 2013, following an open discussion with the community.

The following lists the adopted city of Phoenix base codes and amendment packages. Remember, a complete code package includes both the adopted base code and the Phoenix amendment package. For code adoption effective dates, refer to:

Per Section 16 of Ordinance G5809 adopting the 2012 building codes, any person who has completed more than 50% of the design work on any project may apply to complete the design using the 2006 building codes. Application may be informal and completed by letter or email to the project's Team Leader. If approved, the designer will have until December 30, 2013 to submit the plans for review using the repealed codes.

The city of Phoenix has adopted a few select amendments to include in our 2012 Phoenix Building Construction Code.  These amendments were effective on November 1, 2016.  We don't anticipate adopting the 2015 I-Codes but will begin reviewing the 2018 I-Codes in mid to late 2017 in anticipation of adopting new codes within the first six months of 2018.
