I would let her know you are willing to come by to see if there is a malfunction(assuming they are interconnected). 

I think it is an interconnected game.

Also something else to consider is that the fire code requirements are more involved for a 3-family (interconnected) than a 2, so if it's not already compliant with the 3 family requirements you'd be expected to bring it up to compliance if trying to turn it into a legal 3 family.The phone # for the building department (technically "Department of Inspections and Standards") is 680-5201 and their website is providenceri.com/DIS - as with most city services, I find that I can usually get some help over the phone (sometimes with some waiting on hold), but they are most helpful in person, if that's something you're able to do.On the specifics of that particular property, one option that often comes up with weird utility setups like you describe, is to just have the owner pay utilities.

It looks like Cincinnati you MUST have photo, they RECOMMEND both photo and ion, they RECOMMEND interconnect only the carbon monoxide alarms (does this make sense), you CANNOT install in a  kitchen or within 10 feet of heat, you MUST have smoke in the bedrooms, you MUST have Carbon Monoxide outside the bedrooms. 

For better or worse, the markets are now completely interconnected.
