Cranston's Department of Planning and Development maintains the official zoning map and ordinance text; the city's GIS mapping application is the authoritative source for a parcel's current district.

A published summary is never the authority. The adopted ordinance and the city's official zoning map govern, and both change — verify the district and every standard on your parcel before you rely on it.

How zoning works in Cranston

Rhode Island's statewide accessory-dwelling-unit law applies in Cranston as elsewhere in the state, requiring the city to allow ADUs by right on qualifying owner-occupied lots in most residential districts. We could not independently verify Cranston's current district code letters and numbers against a live source at the time of writing, so this page omits a specific district list rather than risk publishing inaccurate ones — confirm exact designations against the city's official zoning map.

Where a table is coming, it lands in the order the state layer does — and the Rhode Island waitlist below is the queue that decides that order.
