[HISTORY: Derived from Ch. 5, Art. III, of the 1971 Code. Amendments noted where applicable.]
The base line running substantially east and west through the Township shall be as follows: Beginning at a point in the Great Road at the Princeton Township line on the eastern border of such Township, and extending down the middle of Great Road westerly to Harney's Corner; thence continuing in a substantially westerly direction, through the middle of Princeton Avenue westerly to the line of the City of Trenton; which base line shall be the line of division of streets northerly and southerly in the Township; and the base line for streets running in a substantially easterly and westerly direction shall be the line separating such Township from the City of Trenton and the Township of Ewing on the westerly side or boundary of the Township of Lawrence.
In every case in which any street does or shall intersect either of the base lines, the parts of the street situate on opposite sides of the base line so intersected, shall be designated by the terms "North," "South," "East" or "West" as the case may be.
The buildings situated or fronting on any street which does or shall intersect either of the base lines shall be numbered in each direction from the base line as a starting point, the first building on either side of the line being numbered one or two as the case may be; and the buildings situated or fronting on any street, which does or shall terminate at either of the base lines, shall be numbered from the last named base line as a starting point in the manner above stated.
In case of any street which does not or shall not intersect or terminate at either of the base lines, if its direction is more nearly eastward and westward than northward and southward, the buildings thereon shall be numbered from its eastward terminus if the terminus is west of the north and south base line, and from its westward terminus if the last-named terminus is east of the north and south base line; if the direction of the street is more nearly northward and southward than eastward and westward, then the buildings thereon shall be numbered from its northward terminus if the terminus is south of the east and west base line, and from its southward terminus if the last-named terminus is north of the east and west base line.
In all cases in which streets do or shall form an immediate junction which each other, so that the one is but a continuation of the other under a different name, the buildings thereon shall be numbered continuously from the proper base lines as hereinbefore provided.
When any street does or shall run in a direction more nearly eastward and westward than northward and southward, the buildings on the north side thereof shall be numbered with the even numbers and those on the south side thereof, with the odd numbers and when any street does or shall run in a direction more nearly northward and southward than eastward and westward, the buildings on the east side thereof shall be numbered with the even numbers, and those on the west side thereof with the odd numbers.
In all cases where vacant lots do or shall intervene between buildings one number shall be allowed for every 12.5 feet or fraction thereof, being 10 feet or more.
It shall be the duty of the Township Engineer whenever he shall discover that any building in the Township is not numbered according to the plan hereinbefore set forth, to serve upon the owner thereof a written or printed notice of the proper number of such building, which notice may be delivered personally, or left at the building with any person there residing or employed, over the age of 14 years; and the owner of such building, within one month from the date of such service, shall cause the number contained in the notice so served to be affixed to or upon such building in a durable manner, in some conspicuous place, and in default thereof, shall forfeit and pay a fine of $5; provided, that no number upon any building shall be required to be changed merely to give effect to the next preceding section, until, by the erection of a building or buildings upon any vacant lots, a change shall be necessary to prevent the duplication of numbers.
A. 
Where any building is or shall be so constructed that different apartments on the ground floor thereof shall front on any street and be so arranged as to show an intention that the same shall be occupied by different families, or used in carrying on of different trades, each apartment shall be considered as a building, which shall be designated by a separate number.
B. 
The term "street" as used in this section relating to the numbering of buildings, shall be understood to include all private streets and all private and public alleys.
In the case of all streets and highways of the Township which are substantially continuations of streets in the City of Trenton or of the Township of Ewing, the system of numbering in the City of Trenton or in the Township of Ewing shall be continued from the same base line as used in the municipalities and beginning with the next series of numbers, but avoiding any duplications thereof.
The Township Engineer shall not assign any numbers to any street or section thereof without authority by resolution of the Township Council, which shall designate the street or portion thereof for which numbers shall be assigned. In case of any difficulty in assigning the base line or beginning point for numbers, the Township Council shall interpret this section and fix the base line to be used by the Township Engineer in case of uncertainty thereof.
