Building Code Adoption and Amendments

Boulder County has updated and amended the Boulder County Building Code adoptions to the 2021 editions of the International Codes. The current Boulder County Building Code Amendments, which went into effect on March 31, 2025, apply to construction on properties located in the unincorporated portions of Boulder County (outside of the cities and towns), although plan reviews and inspections are currently performed in the Town of Jamestown.

Building Permit Submittal Requirements

Building Permit applications must be submitted using the online applications website.

Please submit one digital file per requested building permit. For example, a new house with a detached garage would be submitted on two separate files, with each permit application (one new house, one detached garage) containing its own set of plans in a PDF file. Separate PDF files are requested for the construction plans, HERS rating, soils report, and water and sewer documentation.

If you cannot find an answer to a specific question, submit your question through the Ask a Building Official webpage form. A Building Official will then research your question and answer within the business day.
