What smoke and carbon monoxide detector duties does a Missouri landlord have?

Check local smoke and CO alarm rules and test the alarms in every unit. Missouri has no statewide smoke or carbon monoxide alarm law for rentals, so the rules come from your city or county code (Springfield, for example, requires owners to install smoke alarms and hand over working alarms at the start of each lease), and a yearly check that confirms your local requirements and tests every smoke and carbon monoxide alarm keeps occupants safe and leaves a dated record.
