Fast Track is a streamlined review and permitting process for qualifying applications. Applicants should be aware that eligible projects go through a more limited review, and the responsibility for code compliance rests on the applicant. Changes may be required to the project upon inspection.  

To find out if your project qualifies for Fast Track, please refer to the Fast Track Eligible Projects sheet. If a project doesn’t qualify it is because additional time for review is necessary to ensure public safety requirements are met. 

After verifying that your project is eligible, fill out Schedule (A, B or C) that corresponds with the type of project and submit when you apply through CSS, along with the applicable permit checklist, required plans and supporting documents. Definitions, setbacks, and other helpful information can be found in the Fast Track Table.

Fast Track reviews typically take an average of 10 business days from the date the permit has been determined to be complete. However, review times may vary depending on the type and complexity of the project and the quality of the submission. Submitting complete and clear application materials will facilitate the review process.

If you have any questions about project eligibility or submission requirements, please contact the Permitting and Inspections Department at or (207) 874-8703.
