Have you ever seen a clause in a commercial lease that read something like this?
Tenant shall return the Leased Premises at the end of the Term in the same condition they were in at the commencement, subject to reasonable wear and tear, and damage by fire and the elements.
At some point, almost all commercial tenants will decide to move into a new space. And for a variety of reasons – expansion, contraction, new lease pricing, etc. However, many times in the fine print of an existing lease, it becomes incumbent on that tenant to return that space to a paint-ready, broom clean condition.
