Oklahoma Smoke & CO detectors

Does a landlord have to provide smoke and carbon monoxide detectors in Oklahoma?

Yes. Owners of apartment houses, rooming houses, hotels and motels and other listed buildings in Oklahoma must install smoke detectors that meet State Fire Marshal codes (74 O.S. § 324.11a(A)). A residential landlord must explain to the tenant how to test the smoke detector; checking that it works is then the tenant's job in one- and two-family dwellings and apartments (§ 324.11a(C)). No state statute requiring carbon monoxide alarms was found.
