With an assembly that incorporates a sensor control component and an alarm notification that detects elevations in propane, natural gas or any liquefied petroleum gas;



B.
That sounds a warning alarm; and



C.
That is approved or listed for the purpose specified in paragraph B by a nationally recognized independent testing laboratory.


A fuel gas detector may be battery-operated, plugged into an electrical outlet or hardwired.

Each unit in any building of multifamily occupancy;

3.
Residential rental units.
In a residential rental unit occupied under the terms of a rental agreement or under a month-to-month tenancy:



A.
At the time of each occupancy, the landlord shall provide fuel gas detectors in accordance with subsection 2 if fuel gas detectors are not already present. Each fuel gas detector must be in working condition. After notification, in writing, by the tenant of any deficiencies in a fuel gas detector, the landlord shall repair or replace the fuel gas detector. If the landlord did not know and had not been notified of the need to repair or replace a fuel gas detector, the landlord's failure to repair or replace the fuel gas detector may not be considered evidence of negligence in a subsequent civil action arising from death, property loss or personal injury; and



B.
The tenant shall keep the fuel gas detectors in working condition by keeping the fuel gas detectors connected to the electrical service in the building or keeping charged batteries in battery operated fuel gas detectors, by testing the fuel gas detectors periodically and by refraining from disabling the fuel gas detectors.






4.
Transfer of building.
A person who, after January 1, 2022, acquires by sale or exchange a building listed in subsection 2, paragraph A shall install fuel gas detectors in accordance with subsection 2 in the acquired building within 30 days of acquisition or occupancy of the building, whichever is later, if fuel gas detectors in accordance with subsection 2 are not already present, and shall certify at the closing of the transaction that fuel gas detectors will be installed. This certification must be signed and dated by the person acquiring the building. A fuel gas detector must be installed in accordance with the manufacturer's requirements at the time of installation in each area containing an appliance fueled by propane, natural gas or liquefied petroleum gas. A person may not have a claim for relief against a property owner, a property purchaser, an authorized agent of a property owner or purchaser, a person in possession of real property, a closing agent or a lender for any damages resulting from the operation, maintenance or effectiveness of a fuel gas detector. Violation of this subsection does not create a defect in title.






5.
Penalties.
A person who violates this section commits a civil violation for which a fine of not more than $500 for each violation may be adjudged. The court may waive any penalty or cost against a violator upon satisfactory proof that the violation was corrected within 10 days of the issuance of a complaint.






6.
Liability.
Nothing in this section gives rise to any action against an owner required to comply with subsection 2 or 3 if the owner has conducted an inspection of the required fuel gas detectors immediately after installation and has reinspected the fuel gas detectors prior to occupancy by each new tenant, unless the owner has been given at least 24 hours' actual notice of a defect or failure of the fuel gas detector to operate properly and has failed to take action to correct the defect or failure.






7.
Noninterference.
A person may not knowingly interfere with or make inoperative any fuel gas detector required by this section, except that the owner or the agent of an owner of a building may temporarily disconnect a fuel gas detector in a dwelling unit or common area only for construction or rehabilitation activities when such activities are likely to activate the fuel gas detector or make it inactive. The fuel gas detector must be immediately reconnected at the cessation of construction or rehabilitation activities each day, regardless of the intent to return to construction or rehabilitation activities on succeeding days.
