    A-4 STREET ADDRESS ASSIGNMENT

  • A.
    RESIDENTIAL
    1. 1.
      Single-Family Detached and Townhouse Dwellings: Each unit of property will be assigned a primary address.

An example would be "1621-101 Smith Street" with "1621" being the primary address and "101" being the secondary address. The secondary address for a multi-story structure on the first floor would include the primary followed by a dash and a unit number beginning with 101. An example would be "1621-101". The first unit on the second floor would include the primary followed by a dash and a unit number beginning with 201. An example would be "1621- 201"; etc. Internal drives may be required to be named and recorded by plat map in the public registry. Addresses may be assigned from internal drives depending on the size of the complex and after considering comments from the Technical Review Committee (TRC).
    3. 3.
      Mobile Home Parks: Each mobile home within Mobile Home Parks shall be assigned a primary address. Internal drives may be required to be named and recorded by plat map in the public registry. Addresses may be assigned from internal drives depending on the size of the complex and after considering comments from the Technical Review Committee (TRC).
  • B.
    COMMERCIAL AND INDUSTRIAL

    Office, commercial and industrial buildings are assigned a primary address for each building and a secondary for each tenant space. The secondary address for a single-story structure will include the primary followed by a dash and a unit number beginning with 101. An example would be "1621-101 Smith Street" with "1621" being the primary address and "101" being the secondary address. The secondary address for a multi-story structure on the first floor would include the primary followed by a dash and a unit number beginning with 101. An example would be "1621-101". The first unit on the second floor would include the primary followed by a dash and a unit number beginning with 201. An example would be "1621-201"; etc. Internal drives may be required to be named and recorded by plat map in the public registry. Addresses may be assigned from internal drives depending on the size of the complex and after considering comments from the Technical Review Committee (TRC).

  • C.
    PUBLIC AND INSTITUTIONAL.
    1. 1.
      Schools
      1. a.
        Elementary and Secondary schools generally are assigned one primary address.
      2. b.
        College and Universities generally are assigned a primary address for each building. Internal drives may be required to be named and recorded by plat map in the public registry. Addresses may be assigned from internal drives depending on the size of the complex and after considering comments from the Technical Review Committee (TRC).

Addresses may be assigned from internal drives depending on the size of the complex and after considering comments from the Technical Review Committee (TRC).
  • D.
    CORNER LOT

    Corner lots are assigned one (1) number to avoid any confusion created by the use in different systems of either of the two (2) addresses assigned to a corner lot, as it was the custom in the past. At the time of permit application, if necessary, the address administrator shall adjust the street address to make it coincide with the primary access to the property. In cases where such assignment is confusing, or misleading based on structure location and orientation or property size and configuration, the administrator can assign an address that accommodates the front entrance of the structure.

  • E.
    LOTS WITH MULTIPLE FRONTAGES

    The Address Administrator shall assign an address for lots with multiple frontages after considering access location(s), primary structure location, lot size, and lot configuration.

  • F.
    VACANT PROPERTIES

    Because there is no way of determining how many structures will eventually be built on vacant land within a block, any system which attempts to number structures consecutively does not provide the flexibility to accommodate change. A street number generally is reserved for each one hundred (100) feet of lot frontage. Address assignment shall occur concurrent with issuance of a development permit.

  • G.
    POSTING

    Posting of addresses by the property owner shall be as per NC State Building Codes.
