What are the setback requirements for decks?

Decks that are less than 50 square feet, have no exterior access and are cantilevered or supported from the main structure may extend three feet into the required front, rear or street side-yard. Such a deck must maintain a setback at least 3 feet from any property line and cannot project more than 6 feet from the supporting wall to its furthest outward extension.
