What is the Residential Walk-Through/Fast Track Permit Process?

There are two types of Residential Fast Track Permits processes - Residential Walk-Through and Residential Intermediate Walk-Through processes.  The processes allow customers to obtain same day building permits for eligible projects.   If the application meets these guidelines and all applicable legislation, in most cases, a customer will be able to obtain the permit in a single visit. 

If the application cannot be completely processed, it will be returned to your team with partial approvals. If the application is for a complex design, structural modifications, or unusual design, it will require extensive reviews. Therefore, the application will be taken in for regular review process. Applications must be on the Residential Walk-Through Fast Track Queue before 2:30 PM - otherwise applications may not be reviewed by the building plan reviewers while you wait and applications would be taken in for regular review process.  

Other Permits

In many circumstances, electrical, mechanical,  fire alarm, sediment controlpublic right of way , well, septic and/or fire protection permits are required to complete the project.

How can I Accelerate my Review Process?
