Building Safety & Inspection Services Information

The Boulder County Community Planning & Permitting Department issues building permits for unincorporated areas of Boulder County. If you have a question regarding building, code enforcement, planning or zoning within a town or city in Boulder County, please contact the municipality directly. View Municipality Contacts Within Boulder County.

The Boulder County Building Safety & Inspection Services Team provides information regarding the Boulder County Building Code Amendments, and administers and enforces building codes in unincorporated Boulder County.

Building Permit Submittal Requirements

Building Permit applications must be submitted online.

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 webform. A Building Official will then research your question and answer within the business day.

Building Code Adoption & Amendments

Boulder County has updated and amended the building code adoptions to the latest 2015 editions of the International Codes. Boulder County Building Code Amendments, which went into effect on January 1, 2016, 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.
