            (ii)    by character or use; or
            (iii)    in any other manner that the Department considers to be helpful or necessary.
        (2)    For the review under subsection (a) of this section, the Department shall perform a physical inspection if:

            (v)    The Department is notified by a county finance officer that a substantially completed improvement has been made that adds at least $1,000,000 in value to the property; or
            (vi)    the Department or the supervisor determines that a physical inspection is appropriate.
        (3)    The Department shall perform the physical inspection required under paragraph (2)(v) of this subsection within 30 days after receiving notice of the improvement.
    (c)    On request of the property tax assessment appeal board for the county in which the property is located, the Director shall order a review of any real property assessment.
