Section 270.450 Alterations
No alterations shall be made on
the premises without the express prior written approval of the Department. In
the event that prior written permission is granted by the Department, all costs
and expenses incurred in connection with said alteration shall be at lessee's
sole expense. The Department will grant approval of minor, non-structural
changes to the premises where said changes do not materially alter the usage of
the leased area for lessee and subsequent lessees, but no approval will be
given where structural changes are contemplated.
