Verify smoke and CO alarms in all units. Connecticut fire and building codes require working smoke alarms in every rental unit and carbon monoxide alarms where the codes call for them, typically in units with fuel-burning appliances, a fireplace, or an attached garage, so an annual documented check that replaces weak batteries and any alarm past its replacement date keeps units safe and compliant.
