In Pennsylvania, a tenant must obtain the landlord's written consent before subleasing their rental unit. In general, Pennsylvania does allow subletting unless it is explicitly prohibited in your agreement.After you find the right subtenant, have them sign a contract. The Guide explains what you should know when applying to rent, living in a rented property, and dealing with the end of a lease. Subletting is when thirdparty rents or "subleases" the property from the original tenant. Some leases in Philly allow subletting, meaning another person can live in the apartment and pay rent while you travel or work elsewhere. Subletting allows tenants to lease out their rental to a new occupant. Subletting is the same as subleasing; the two words are interchangeable. As long as your landlord, or state law, approves, anyone can sublet. This agreement allows the sublessor to rent the property to the sublessee for some or all of the original lease term.
