IN THIS BULLETIN:

This Information Bulletin describes the estimated due dates for building permit applications submitted to the Development Services Department (DSD). These are estimates and are not guaranteed, as DSD cannot limit the number of submitted projects, so the workload is variable.  

For example, DSD often receives more Building Permit applications in the month before a new building code is adopted. Still, DSD works to meet the estimated due dates as much as possible. View the average review times for a variety of review disciplines. 

Projects that qualify for Rapid Review are not included in the tables below; projects in Rapid Review receive due dates of 6 business days for the first review and 2 business days for rechecks. 

 I. Building Permit Applications 

When a building permit application is submitted, the size of the project is determined based on the tables listed below. If the project includes multiple buildings, the next category will be used. If more than 50% of the existing building square footage is removed and reconstructed, the building will be considered a new building for the purposes of due dates.
