Portable sheds that are no larger than 200 square feet, no taller than 10 feet, and not permanently affixed to the ground may be placed anywhere on a property and do not require a building permit. Other types of accessory buildings that are taller than 10 feet, larger than 200 square feet, permanently affixed to the ground, and/or connected to utilities, require a building permit. Building permits are issued by the Planning and Risk Reduction Divisions. Visit with Planning or Risk Reduction staff for questions about permitting requirements.
