Do you need a permit for Deck Construction in Washington County?
In Rhode Island, a Deck Construction requires a building permit.
The only exception is a small freestanding platform 200 sq ft or smaller and no more than 30 inches above grade that is not attached to the house (IRC R105.2); any attached or elevated deck needs a permit. Plans are reviewed under the Statewide code (IRC 2021); apply through State of Rhode Island Building Code Commission before work begins.
