I live in Maine and have a multi-unit home with two units — a first-floor unit and second-floor unit — that I rent out. The two units share the same foyer, and the tenants do not know each other well.
The tenant on the first floor recently acquired an adult male pit bull, which I have so far permitted under the lease agreement. The dog is not under the owner's vocal command, so by Maine law the owner must keep the dog on a leash when not on property. However, he often has the dog off of a leash when he is outside of his apartment — for example in the foyer, on the porch, and around the yard — and the other tenant has expressed concerns about safety, for instance when she is exiting her second-floor apartment through the foyer.
Does Maine state law or court precedent require that the dog be leashed on the rental property? This information would be helpful for determining how I should approach the situation.
