I live in a rental house in Phoenix that didn't come equipped with smoke alarms or carbon monoxide detectors. I've looked everywhere online and I can't find any State of Arizona or City of Phoenix Housing Codes regarding this matter. The Tenant-Landlord Act also doesn't cover this issue. Is it my responcibility to buy, install and maintain things like this? Every rental property that I've ever lived in in Arizona has had smoke alarms installed, so it was never an issue before.
