"There are many grounds to evict a tenant. First and foremost has to be the non-payment of rent. You must pay your rent every month or you can be evicted. Also, you can be evicted if your lease has expired. Obviously, the landlord must give the tenant ample notice. You may be evicted if you have no lease and your tenancy is month to month. The landlord must give the tenant, normally, a 30
. day notice, and then may proceed to evict. You can also be evicted if you violate the terms of the lease. For example, you can be evicted if you have a pet in violation of your agreement, or if you keep your apartment/home in extreme disrepair.http://www.tenant.net/Other_Areas/Penn/harris/pa-toc.html"
