Codes and Regulations
Development in the City of Boulder requires conformance with all adopted building codes, all land use regulations, and the city’s design and construction standards. These codes, rules and regulations comprise the minimum standards required for development in the City of Boulder.
Adopted building codes consist of the International Code Council's (ICC's) 2012 family of codes, with local amendments 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.
The city updates its codes on a regular basis to ensure that the regulations keep pace with changes in the construction industry.
