Agreed Use refers to the purpose for which the tenant intends to use the space. In this section of the lease, the landlord is not justifying that the agree use is legal, but rather that they are okay with that specific purpose. A potential tenant has the responsibility of determining whether or not its intended use is legal.
The descriptions for intended use may be generic or specific. This is important because it will affect the tenant’s ability to sublet the space in the future. If the description is very specific, the landlord can make the argument that only a subtenant with the exact same use will be approved for a sublease. Typically, tenants will be as generic as possible and landlords will be as specific as possible. A small point that can have a big impact!
