Building Code Information

The City and County of Broomfield has adopted the 2015 International Code series, effective . This means that all permits issued as of April 1st, 2017 will need to have plans designed, reviewed, and approved by the Building Division to meet the 2015 Codes. This will include the architectural plans, structural framing plans, structural foundation plans, soils reports, roof truss plans, and energy code documents. Below is a short summary of significant changes from the 2012 to the 2015 codes.

Building codes are updated every three years through an open consensus process to adapt to changing technology, current methods of construction and in reaction to situations where codes may have failed to protect the public in the past. Building inspection and plan review staff must constantly update their code knowledge and assist builders in meeting the most recent edition of these national codes, as adopted by the City and County of Broomfield.
