Looking for Philadelphia landlords

[Eric Armstrong]

I have a couple questions about the landlord laws in Philadelphia. My mother in law rents there and I trying to figure out who would be responsible for certain costs. 1. Her neighbor noticed there is a small crack in a window pane. Prop management company has asked her to try to identify who did it and to send them a letter to repair it. 2. Can a landlord charge a tenant for trash removal services? Weekly trash service, not random large bulk items. Shouldn't it be a part of the monthly rent and not a separate change? 3. What is the law for maximum fee for late rent? Thanks Eric
