State Laws and Rights
Oklahoma mold law snapshot
Oklahoma does not have a mold-specific statute, but habitability rules still apply.
Under Oklahoma Statutes Section 41-118, landlords must at all times during the tenancy: (1) keep all common areas in a clean, safe, and sanitary condition (except for single-family residences); (2) make all repairs and do whatever is necessary to put and keep the tenant's dwelling unit and premises in a fit and habitable condition; (3) maintain in good and safe working order all electrical, plumbing, sanitary, heating, ventilating, air-conditioning, and other facilities and appliances supplied by the landlord; and (4) provide appropriate receptacles for waste removal. This implied warranty of habitability applies whether or not the lease explicitly states it and even if the lease attempts to waive the obligation.
