Codes are primarily adopted and enforced locally.
Some jurisdictions have adopted the 2012 IECC.
Code adoptions are based on the local jurisdiction code change process.
There is no state building code other than a minimum code adopted by the Arizona Department of Health Services for licensed health care facilities. Major jurisdictions in and around Phoenix have adopted the 2018 Editions of the codes. (https://www.phoenix.gov/pdd/devcode/buildingcode) Phoenix adopted the 2018 editions.
Since codes are adopted by jurisdiction and they are still on the 2012, 2015, or 2018 I-Codes, adoption of IRC Section R302.13 is unknown. Phoenix did not include this provision in the update of their 2012 I-Code adoption.
