International Code Council (ICC) Codes

The City of Boulder has adopted the 2012 International Code Council (ICC) codes, which went into effect on Jan. 31, 2014. Local amendents are in Title 10 of the Boulder Revised Code.

Local amendments to the ICC family of codes have been kept to a minimum and are defined according to the community vision of the Boulder Valley Comprehensive Plan. Other sections of the Boulder Revised Code may apply to your project and advance consultation with a Project Specialist is highly recommended.

On Oct. 1, 2013, City Council approved "Ordinance No. 7925" to adopt the 2012 International Codes by reference, with amendments. Select the "Changes to the International Building & Residential Codes" link for more information.

To view printed copies of the building codes, visit the Planning and Development Services (P&DS) Center at 1739 Broadway, third floor. P&DS also has order forms available for customers wishing to purchase the codes. The ICC codes can also be viewed free online here.
