Can a PA landlord ban their tenants guests from visiting them?

[Brittney Cain]

Do any of you know the law on whether or not landlord can ban guests from visiting their tenants apartment?

I recently visited my mother, who rents the apartment, and I got into an argument with another tenant. The tenant harassed me twice this year by cussing me out and telling me that I cannot park in a specific spot in a free for all 12 parking spot lot. There are not designated parking places so I feel as though I can park where I want. She told me to move my vehicle to a different spot and I said no. I was leaving in 20 mins anyways. She called the landlord. The landlord refused to hear my mother’s side and banned all of my mothers family from visiting now. The tenant who was arguing with me lived there 20 years whereas my mother has only been there for a few years.

Is this actually legal?
