Deck Construction Permits in Overland Park

Local Rule

City of Overland Park Building Codes Division

The city's own Residential Decks document states the exemption with a distinctive measurement method: a detached deck stays exempt from a building permit only when it does not exceed 200 square feet and is not more than 30 inches above grade, measured 36 inches out from the perimeter of the deck at any point, rather than simply at the deck edge itself. The same document sets real setback exceptions specific to decks: a deck under 30 inches high may sit as close as 3 feet to the rear property line, and an open deck or porch may project 6 feet into the front or rear setback if the encroachment area does not exceed 60 square feet.
