A. SUMMARY This dataset delineates parcels with “Taxable Commercial Space” - meaning parcels where one or more property owner(s) and/or commercial tenant(s) are required to file or pay the Commercial Vacancy Tax. The dataset includes the Block, Lot, Parcel Number and Parcel Situs Address for each commercial parcel within the named Districts. Information about each filing received for the parcel is included, such as Filer Type (Owner / Tenant), Filer Name, Parcel Situs Address from the Filing, and Tax Year filed. The dataset also includes whether a parcel is vacant, and if so, the tax rate applied. A single parcel may have multiple addresses and/or filings depending on the number of units and access points. Parcels marked as vacant either reported as vacant in the tax filing or were determined to be vacant by the Tax Collector. All information displayed is subject to audit by the Tax Collector.
