Arizona Smoke & CO detectors

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

Arizona requires an approved smoke detector in every new residential housing unit, and in an existing unit when a sleeping area is remodeled under a local permit. The tenant must keep the detector working unless the tenant tells the landlord in writing that it is malfunctioning, in which case the landlord must repair it. The landlord must give the tenant written notice of these tenant responsibilities. Statute text: "A smoke detector installed in a new residential housing unit or in a remodeled area pursuant to this section shall be maintained and kept operable by the tenant unless the tenant gives written notification to the landlord of its malfunction." (A.R.S. § 36-1637).
