Pennsylvania state laws do not provide detailed instructions for subleasing, which means tenants must often refer to their lease agreements. A sublease agreement is considered a written document that offers the lessee a chance to pass on the responsibility and rights of tenancy to another person.A Pennsylvania sublease agreement formalizes a rental arrangement between a current tenant (sublessor) and a new tenant (sublessee). Tenant shall not lease or sublease without written consent of the Landlord (but consent shall not be withheld unreasonably). A sublease agreement is a legal contract signed between a tenant and a third party allowing the latter to rent out the entire property or any part of it. In Pennsylvania, a sublease agreement is a type of lease agreement between two tenants, instead of between a tenant and the landlord. It depends on the terms of the original lease with the landlord; namely, whether it allows subleases. A landlord may ask you to fill out a rental application. The sublease agreement is tied to and incorporates the original (master) lease. In Pennsylvania, the language in the original lease controls the process.
