Legal Question in Landlord & Tenant Law in Pennsylvania

Why would the landlord be responsible? Did you notify the landlord, in writing, of a mouse infestation? You might want to do so. If the landlord refuses, call the county health department and have them inspect. If they agree that the house is infested and unhabitable, you can use this in order to get out of your lease. Your landlord will not be alloweed to charge any rent to yuo until he solves the problem.
