Do I need a permit for deck construction or replacement in Unincorporated Morrow County?
It depends. Whether deck construction or replacement needs a permit in Unincorporated Morrow County comes down to the details of your project.
The ORSC exempts porches and decks whose walking surface is not more than 30 inches above adjacent grade at any point within 3 feet horizontally of the walking surface (R105.2 item 10); the exemption has no square-footage limit. A deck more than 30 inches above grade, and a stairway to the primary door or to a porch or deck more than 30 inches above grade, needs a building permit. BCD publishes permit-ready deck plans that meet the ORSC; a cover over the deck is a separate item that is exempt only up to 200 square feet and at least 3 feet from lot lines.
