address zone
A section of a structure distinguished by its own house number within the local street-address system.
An address zone is a section of a structure defined by a distinct house number on the local street grid.
The distinct house number defines the section. A different tenant or use does not by itself establish a separate address zone.
Several address zones can belong to one structure. The address division describes their relation to the street grid rather than requiring separate freestanding buildings.
