It probably varies by state. In California, we have to have at least one (per floor? or per living space) with fresh batteries in it when the tenant first moves in.
It might vary by city, even. I know, however, that we as landlords in Somerville are required to have smoke detectors for our 3rd floor tenants. I think we might need to get one for each floor, come to think of it. And in S'ville, we're required to have them hard-wired into a dedicated circuit of electricity that isn't on the tenant electric bill. Whee! :)
Ours can be battery powered, and though landlords have to make sure there's a fresh battery in it at renting, the tenants are responsible for changing the battery regularly enough.
