a. As used in the charter and in the code, the term "tax maps" shall mean and include the block map of taxes and assessments to the extent that the territory within the city of New York is or shall be embraced in such map, such ward or land maps as embrace the remainder of such city, and also such maps as may be prepared under and pursuant to subdivision d of this section.
b. Each separately assessed parcel shall be indicated on the tax maps by a parcel number or by an identification number. A separate identification number shall be entered upon the tax maps in such manner as clearly to indicate each separately assessed parcel of real property not indicated by parcel numbering. Real property indicated by a single identification number shall be deemed to be a separately assessed parcel. In the case of a newly created parcel with any building thereon, no tax lot number or identification number shall be assigned to such parcel unless the commissioner of the department of buildings has certified that the newly created parcel complies with all applicable zoning laws.
c. Parcel numbers shall designate each parcel by the use of three or more numbers, of which one shall be a section or ward number, another a block, district or plat number, and another a lot number. The department of finance may from time to time change the form of the section and blocks, and also the numbers thereof, on the tax maps filed in its office whenever such change of form has been caused pursuant to section one hundred ninety-nine of the charter, and there shall thereafter be delineated and entered upon such maps such new additional sections and blocks and their numbers as necessity may require. Such administration may from time to time change the form of the lots or parcels comprised within any block, and also the numbers thereof, and cause to be shown on such maps the separate lots or parcels of land contained in any new block added thereto and also the lots numbers thereof, according to the general plan employed in the making of such maps.
d. Each separately assessed parcel indicated by an identification number shall be shown by a description, or by inscription of such number on the block map of taxes and assessments, or by other map and description. Such numbers may be altered in the same manner as provided in the preceding subdivision for the alteration of parcel numbers.
e. New tax maps shall be certified by the department of finance and filed in its main office, and substituted for use in its offices and in those of the department of environmental protection with respect to maps affecting the boroughs of Manhattan, Bronx, Brooklyn and Queens, instead of the maps theretofore in use therein. All changes and alterations made in the tax maps shall be transmitted within thirty days after such change or alteration to such offices.
f. On or before July first, nineteen hundred sixty-four, the department of finance:
(i) Shall certify and file a map showing the boundaries of each and every tax block and its tax block number in the boroughs of Manhattan, Bronx, Brooklyn and Queens, with the city register, and with the clerks of the counties of New York, Bronx, Kings and Queens,
(ii) Shall certify and file a copy of the tax maps for the year nineteen hundred sixty-four-nineteen hundred sixty-five for the boroughs of Manhattan, Bronx, Brooklyn and Queens with the city register, and

All changes and alterations made in the block boundary maps and in the tax maps shall be transmitted within thirty days after such change or alteration to such county clerks and city register.
