Permit issuance periods vary. Some projects, such as re-roofs, water heaters, window replacements, etc., can be fully permitted over-the-counter, meaning a return trip will not be needed. Other projects, however, require the plans be left for additional review. Most single-family dwellings, additions, and garages will be commented on within 7 – 10 days. Commercial projects require a longer time period for Building and Fire Plan Review.
