Federal law says all apartments have to be “habitable under minimum conditions” meaning they need to have working appliances, the lights and HVAC need to function properly, and in general, a person needs to be comfortable. In other words, when I pay rent, it gives me, by law, “the right to quiet enjoyment.”
The places need to be painted, and no smoking is allowed. Cupboards need to be sturdy, all inner doors must be functioning properly, and windows need to have screens. If the area has high crime, there needs to be a security door at the entrances and if necessary, bars on the windows.
The rest depends on whether it’s for families or seniors. At this point, I just want to move!
