Sun Prairie deck permit
Sun Prairie asks for a building permit application, a drawing that follows one of three accepted construction methods, and a site plan. Decks up to 3 feet high may come within 8 feet of the rear property line; taller decks must stay 24 feet back. A roof over the deck means larger setbacks, and a pergola needs a permit only if it is attached to a building.
