In Pennsylvania, residential and commercial lease agreements are governed not only by the terms of the lease itself, but also by the Landlord and Tenant Act of 1951, 68 P.S. §§ 250.101, et. seq.
When a lease term ends, the landlord is required to provide a tenant with a list of damages caused to the premises within thirty days of the termination of the lease or repossession of the property.
In addition, the landlord must return any escrow monies held under the lease within that time period. If the landlord deducts any funds to pay for alleged damages to the premises, then the landlord must return the difference in the balance of the escrow funds to the tenant.
