The following guidelines shall apply to pre-existing, changed, and new addresses.
(A) Number assignment. Assignment of address numbers shall be based upon where the driveway intersects the main street, except where otherwise specified by this chapter.
(B) Conflicting numbers. The owner or occupant shall remove any pre-existing or different address numbers that might be mistaken for or confused with the proper number that has been assigned by the ETSB to the structure.
(C) Dimensions. Address numbers shall be a minimum of three inches in height, shall be affixed near or on the main entrance to the structure, and shall be visible from the street named in the address. All house numbers shall be in Arabic numerals (i.e., block print). Address numbers shall contrast with the surrounding surface so as to be readily identifiable and may be arranged horizontally or vertically.
(D) Restrictions on numbers. Numbers evenly divisible by 100 shall not be used in assigning house numbers. Fractions shall not be used in assigning house numbers. A new address shall be assigned by the ETSB to correct any pre-existing address that uses a fraction. There shall be no use of fractional addresses, alphanumeric address numbers, nor hyphenated address numbers (i.e., 134-1/2 Ash Street, 123A Main Street, or 41-656 Bell Street).
(E) Mailboxes. When the structure is more than 50 feet from the street named in an address, or when the entrance of the building is not visible from the street, the address number shall also be mounted on a post, sign, wall, fence, or mailbox that is on the same side of the street as the addressed structure, within ten feet of the driveway, and not more than 20 feet back from the street, and shall be readily visible from the street when approaching from either direction. (Mailboxes that are grouped, that are on the opposite side of the street from the structure, or that are located away from the driveway that serves the structure shall not be used for displaying house numbers as defined in these rules, because the mailboxes may not allow house numbers to be viewed from either direction and/or may not provide adequate identification of the location of the addressed structure. The mailboxes should be labeled according to United States Postal Service guidelines for proper mail delivery.)
(F) Multiple-use situations. Any site which includes multiple apartments, suites, spaces, or other units must include the appropriate unit designator and number in the address following the street name. Appropriate designators shall be APT/Apartment, BLDG/Building, CBN/Cabin, DEPT/Department, STE/Suite, SP/Space, FL/Floor, TRLR/Trailer, HNGR/Hanger, UNIT/Unit, LOT/Lot. Basement unit numbers shall be three-digit numbers beginning with “0” (APT 005), first-floor unit numbers shall begin with “1” (UNIT 108), second floor unit numbers shall begin with “2” (STE 210), and the like.
(1) Apartment houses. A building under one ownership in which rooms are arranged and rented as apartments. The apartment house shall be given one street number and each individual apartment shall be given an apartment number. Example: “250 W. Elwin Road APT 103”.
(2) Residential condominium complex. A building or buildings with individual, separately owned units in a multi-unit structure. The private street serving the building(s) may be given a name. Each condominium unit structure shall be given its own street number. Units in the same structure shall have a unit number.
(3) Commercial complex. A building or buildings under one ownership, used for commerce or industrial use. If each unit within a building has its entrance off a common interior hallway, then each building shall be given its own street number and each unit within the building shall be given its own unit or suite number. The building number shall be displayed on or near the main building entrance and each unit or suite number shall be displayed at each unit’s entrance. If each unit within a building has its own street entrance, not off a common interior hallway, then each unit shall be given its own street number. Each unit street number shall be displayed on or near that unit’s main entrance.
(4) Commercial complex with apartment complex. A building or buildings used for commercial use in which there are also apartments. Each building shall be given its own street number, each commercial unit shall be given a respective unit or suite number, and each apartment shall be given a respective apartment number. At no time shall there be unit or apartment numbers within a complex that are the same.
(5) Duplex; a two-family residential structure. Each family unit shall be given its own street number. If multiple duplex buildings are served by a private street, that street may be given a name and the duplex units addressed off that street.
(6) Multiple-address locations. For plazas or other commercial occupancies with multiple addresses, the posting of the range of addresses on the main plaza or occupancy sign, readily viewed from the street, is encouraged.
(G) Pre-addressed recorded subdivision plats. As a general rule, subdivision plats of record may be pre-addressed by the ETSB in accordance with these rules. Addresses identified on recorded surveys which are not approved by the ETSB and recorded in the addressing database are not valid and shall not be used for physical addressing purposes.
(H) Corner lots. When assigning a number to a principal structure that does not prominently front on a street and is located on a corner lot, a number from the street with which the main driveway intersects shall be assigned. Any principal structure on a corner lot that prominently fronts on a street may be assigned a number upon that street regardless of the driveway location. Dual addresses shall be avoided.
(I) House numbers along diagonal, meandering, or curvilinear streets. Where the street does not run directly north-south or east-west, the general course of the street is to be used in determining the house numbering direction.
(J) Suffix letters and numerals. Planned suffix letters and/or numbers for multiple-occupancy dwellings, mobile home park spaces, office suites, and other buildings or developments that are divided into address units shall be submitted to the ETSB for approval prior to being adopted by the property owner(s).
(K) Unincorporated area. A municipality’s house numbering system may be used by the ETSB to number properties in the unincorporated area of the county along the streets and streets that border that municipality or that are likely to be annexed by that municipality in the relatively near future.
