What is an Express Permit and how is it different from a regular building permit?

Express permits are building permits with a streamlined application process. They are to be used for a specific list of maintenance-related work on residential structures only: Roofing, Siding, Deck Re-surfacing (no framing), Window or Door Replacement (same sizes only – no framing changes) and insulation. The fee is fixed at $50. per category per structure (e.g. $50 for siding replacement, $50 for roof replacement, etc.) Homeowners and Contractors may both apply for Express Permits.
