Vacate orders 0 active of 1

Orders to leave a building, in whole or in part, from DOB complaint dispositions and from HPD. Per city records, an order is active when the latest vacate served (full or partial, including a MARCH code that issues a vacate) has no later full rescind. A partial rescind is noted and does not clear the order. DOB complaint data can lag the DOB BIS property profile; confirm a DOB order there.
