Building Code, Policies, and Guides

The building code for the City and County of Denver is based on the 2014 National Electrical Code, NFPA code 72 (National Fire Protection Association) and the 2009 Series of I-Codes. 

Building code policies provide detailed descriptions of how to handle certain situations that are not clearly addressed within the Denver amendments or within the current codes.

The current Denver Building Code (PDF) (Revised September 2012) contains all amendments to the adopted building codes and fire codes.   The codes are amended to address the specific needs within the City and County of Denver.   

You may purchase a copy of the codes developed by the International Code Council (ICC).  For more information please visit the ICC site. Please note that this site is not a part of
