Sheds and Accessory Structures

A building permit is required to build, demolish or alter any carport, garage or shed that is greater than 200 square feet in area (measured from the interior side of the exterior walls) or exceeds a height of 15 feet, measured from grade plane to the average height of the highest roof surface.  Depending on the scope of work, your project may also require electrical, plumbing or mechanical permits.

A building permit is not required to construct a non-habitable accessory structure that is 200 square feet or less in area if it does not exceed a height of 15 feet, measured from grade plane to the average height of the hightest roof structure.
