Flood Recovery Information

The Flood Rebuilding & Permit Information Center is a resource for those facing rebuilding following the 2013 Flood, and is staffed by functional experts in onsite wastewater (septic) systems, floodplain regulations, transportation (driveways, roads & bridges), planning and building codes. Review Rebuilding for information on minor flood restoration and repair to residential structures.

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.

Please contact the Building Safety & Inspection Services via the Ask a Building Official or call 303-441-3926 if you have questions or need additional information about this change.

Building Permit Submittal Requirements

In an effort to reduce the amount of time required for building permit approval, the Boulder County Land Use Department has revised the items we require for a building permit application. Any building permit application now requires two paper copies of construction plans and one digital version of the files.

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.
