What is the name of your state (only U.S. law)? Massachusetts
I have a first floor tenant in a 3 family who i've been getting complaints about. They are a young couple with great references. They came in and painted the whole place. The people upstairs had been complaining about children running around and making lots of noise. The tenant said that her friend and kids moved in because she lost her apartment. I told her that you can not move people in that are not on the lease and that the apartment is not deleaded so children should not be living there. (the city offers grants for deleading so I would have had it deleaded had I known and it would cost me no money).
My good tenants upstairs who have never complained in two years are still complaining. The first floor tenant says her friend moved out but still comes to visit a lot. However, the other tenants say that the woman with the children is still there and that her car is parked out front all the time. Each time I drive by-- 3 or 4 times in middle of the day, 1AM, etc-- I see the car.
The first floor pays on time and seems good otherwise. I'm not sure if her boyfriend moved out and she needed another person to help pay or what. The noise is not my biggest concern but children living there while not deleaded is an issue.
I have taked to the first floor a couple times about the noise and she said she didn't think the noise was excessive and that her friend is not living there. I have not approached her since realizing the friends car is there all the time. She could just say the car broke down and she left it there.
What should I do?
