Permits from the Planning and Building Divisions are required for all decks over 2.5 feet above the ground or decks that are covered by a roof or canopy for an area of 200 square feet or greater. The permit ensures the structure is safe, complies with setbacks, and not harmful to utility lines, the environment, etc. If a residential deck is less than 2.5 feet above the ground and either uncovered or covered for less than 200 square feet, a building permit is not needed and the setback requirements below do not apply.
