State Laws and Rights
Rhode Island mold law snapshot
Rhode Island does not have a mold-specific statute, but habitability rules still apply.
Under Rhode Island General Laws Section 34-18-22, landlords have a statutory duty to maintain rental premises in a fit and habitable condition. This includes complying with all applicable building and housing codes affecting health and safety, making all necessary repairs, keeping common areas clean and safe, and maintaining all electrical, plumbing, sanitary, heating, ventilating, and air conditioning systems in good working order. Landlords must also supply running water, reasonable hot water at all times, and reasonable heat between October 1 and May 1. Rhode Island also has a statewide Housing Maintenance and Occupancy Code (R.I. Gen. Laws Chapter 45-24.3) that establishes minimum housing standards enforced by local municipalities.
