A permit is not required for a one-story detached accessory structure of 200 square feet or less used as a tool shed, storage shed, playhouse, or similar use; additions to a house require a permit regardless of size. Window replacement is exempt when headers are not moved/altered/replaced, subject to emergency-escape-opening requirements. A detached deck may be exempt when it is no more than 200 square feet, no more than 30 inches above grade, unattached to a dwelling, and does not serve the main exit door.
