The owners of all buildings or property within the Township to which street numbers have been assigned in accordance with the Allegheny County 911 system shall have the street number prominently displayed at all times in accordance with the following standards. For the purpose of this chapter, a "street number" is an address number established in accordance with the countywide 911 system with reference to the adjacent road or street assigned and given to a particular building or property:
A.
Each building to which a street number has been assigned shall have a street number displayed upon the mailbox and/or the building (if applicable) except for buildings which are located a distance greater than 50 feet from the nearest public or properly marked private roadway or upon which signage cannot be attached or would not be readable from the nearest public or properly marked private roadway by reason of natural or man-made obstructions, the owner of said property shall be required to provide posted signage within 20 feet of the public roadway, which post shall have affixed thereon the street number which has been assigned to the building.
(1)
The signage on the house shall be within the proximity of the front door.
(2)
Numbers of signage within 20 feet of the roadway shall be placed on a post in a vertical position four to five feet in height.
(3)
Numbers are to be legible and distinguishable of not less than two inches in height for the mailbox and not less than four inches in height for the building.
B.
If, for any reason, the street number of a particular building is not readily identifiable by posted signage along the public or properly marked private roadway whether due to the proximity of multiple buildings with different street numbers or some other reason, then the street number should be affixed to the building as well as posted by the road. Similarly, if a single building has multiple street numbers or apartment numbers, such as a professional building or apartment, a building directory should be posted at the main entrance of the building.
