Frequently asked questions — Rhode Island permits

The Coastal Resources Management Council regulates development within 200 feet of Rhode Island's tidal waters and coastal wetlands. A CRMC assent is required before permits can be issued for affected properties.
Rhode Island's RIGL 45-24-31 allows accessory dwelling units by right on any single-family lot statewide. Municipalities cannot require owner-occupancy, additional parking, or design standards stricter than the primary home.
Rhode Island's frost depth is 48 inches — one of the deeper requirements in New England. All exterior footings must be below this depth.
Any work near tidal water or coastal features requires both a local building permit and CRMC approval. Start the CRMC process early — it can add months to a coastal project timeline.
