The DC Office of Zoning uses this query layer, which is a spatial join between theZR16 zoning polygonsand theCommon Ownership Lots, to show zoning information at the lot level. This layer aids theonline zoning mapto show zoning information by address. The PREMISEADD field is the address that is identified as the lot's primary address for tax purposes. Note that this field also contains the city/state/zip code; and the addresses in the query layer will not make up a comprehensive list because of the many-to-one relationship. There can be multiple addresses on single lot.
