The Tenant will be responsible for these matters, with the extent, and nature of these liabilities, expressly stated in the commercial lease. If the lease is for part only of the building, the landlord will likely covenant to repair the structure and common parts of the building or property and recover such costs from the Tenants through the service charge. If the lease is of a whole property, the Tenant will be required to put and keep the property in a good state of repair and condition (but this could be limited to the state of repair and condition at the commencement of the lease, usually evidenced by a photographic schedule of condition).
