Rhode Island General Laws Title 23. Health and Safety § 23-27.3-120.4. Changes in use and occupancy

After a change of use has been made in a building or structure, the reestablishment of a prior use that would not have been legal in a new building of the same type of construction is prohibited unless the building complies with all applicable provisions of this code or the rehabilitation building and fire code for existing buildings and structures as applicable and the Fire Safety Code (chapters 28.1 --28.39 of this title). A change from one prohibited use, for which a permit has been granted, to another prohibited use shall be deemed a violation of this code.
