The US Postal Service is a landlord as well as a tenant. As a landlord, the USPS leases space in USPS owned facilities, and subleases space in USPS leased facilities. Leasing provides extra income for the Postal Service enabling it to keep owned properties, and remain in leased properties.
USPS leases have long allowed the USPS to sublease the premises under the General Conditions of the lease. From the October 2006 lease form: “The Postal Service may sublet all or any part of the premises or assign this lease but shall not be relieved from any obligation under the lease by reason of any subletting or assignment.” The New 2018 Lease Form adds that subletting or assignment can be done “only with the prior written consent of Landlord, such consent not to be unreasonably withheld, conditioned, or delayed . . .” and that “If Landlord fails to respond in writing to a written request to sublease or assign from the Postal Service within 10 business days after receipt by Landlord of the Postal Service’s written request, Landlord shall be deemed to have consented to such sublease or assignment, as applicable.”
