Landlord obligation under "will not disturb the peace and quite"

[Usman T.]

I have 4 tenants that are roommates, that are sharing an apartment together in Philadelphia, PA.  One roommate is complaining that the others are:

1. Threating her
2. Moving her stuff
3. Not allowing her at all enter or exit the apt. or to do so in a safe manner.

Am I under any legal obligation to assist?Is this a violation of tenant “will not disturb the peace and quite of other tenants”?

Personal conflicts between roommates is not your problem. Stay out of it.  Tell them to resolve their problems and if one or more decides to leave you do nothing. Keep them all on the lease till it ends. If they choose to bring in a new room mate you must screen and approve.
