Building Permit Review Process

The City of Boulder uses a phased review process. The review is divided into two phases. The first phase includes reviewing zoning and engineering issues. The second phase includes reviewing building and utilities issues. This process allows for a coordinated review from several staff members to process your application more efficiently.

Review times vary according to the scope of the project and the clarity and completeness of submitted materials. Check the status of a permit online using the "Permit Status Report" in the related links section.

How long does it take to get a permit?

When you submit your completed application, the project specialist will give you an approximate date when you can expect to hear from the city. The actual time it takes to receive approval is determined by the clarity and completeness of your application materials, as well as the number of other applications awaiting review. If your submitted documents are complete, accurate and meet all the code requirements, the possibility of your application requiring resubmittal is reduced.

Over-the-counter permits

For some smaller projects such as fences, roofs, single family electrical systems, and single family heating and air-conditioning systems, a permit may be issued over the counter. A project specialist in the Planning & Development Services Center will determine if your permit may be issued at the time of application or if it will need to follow the review process. The specialist will be able to give you an estimate on how long the process will take if it has to go through review.
