[HISTORY: Adopted by the Annual Town Meeting of the Town of Southampton 6-7-2022 by Art. 6 (Art. XXIII of the General Bylaws). Amendments noted where applicable.]
In the interest of public safety and to facilitate emergency responses, the Town needs a comprehensive system to number buildings on or near the line of public or private ways. Every building under construction, renovation, or transfer of ownership, including, but not limited to, single- and multiple-family dwellings, apartment buildings, condominiums, municipal buildings, and all types of business establishments, shall have affixed thereto a number representing the address of such building prior to the date of occupancy. Buildings must display address numbers that are at least four inches in height.
Numbers shall be numeric and must meet the minimum size as designated in § 127-1. The numbers shall contrast with the background to which they are affixed to ensure readability without sight aids from the public or private way on which such building is located.
If the building is located more than 80 feet from a public or private roadway, such building number shall also be:
A. 
Affixed to a sign (less than one square foot) at the intersection(s) of the public or private way(s) on which such building is located;
B. 
Displayed on signs that meet the same size and contrast requirements as numbers affixed to the building; or
C. 
Attached to both sides of a roadside mailbox, with four-inch-high, contrasting numbers as an acceptable alternative to a sign, when said mailbox is located on the same side of the public or private way as the building. For homes without mailboxes or when the mailbox is located on the opposite side of the public or private way on which the house/building is located, the following shall apply:
(1) 
Signs must be visibly located at the driveway or lot entrance;
(2) 
Address numbers must be four inches in height; and
(3) 
Numbers must be attached to both sides of a sign.
The address requirements for estate or subdivision lots are as follows:
A. 
A clearly designated house number sign, not exceeding four feet in height and six feet in width, depicting house numbers and locations within the estate or subdivision must be displayed.
B. 
Mailboxes shall not suffice as home/building identification for estate/subdivision lots.
C. 
Address sign permits for estates/subdivisions shall be issued by the Building Department. Failure to obtain a sign permit after 30 days of notification from the Building Department shall result in a continuous fine for every day of violation as specified by Chapter 203, Noncriminal Disposition, of the Southampton General Bylaws. No permits in relation to the site can be finalized until compliant with this section.
Houses under construction shall install a permanent or temporary house number (spray paint on plywood is an acceptable temporary sign) for the purpose of delivering emergency response aid to personnel engaged in lot development or home construction.
The Building Commissioner/Inspector shall be the designated enforcement authority and shall apply these requirements to all new construction and/or renovations that require building permits.
