Owners of all houses and commercial buildings shall post the numbers of said house or a building in a manner which causes the numbers to be visible from the street fronting the house or building. The numbers shall be at least three inches (3") in height and shall contrast distinctly with the background which they are placed, so they are readily visible at night from the street to which the number relates. Reflective numbering may be used as an alternative. For nonresidential and mixed residential/nonresidential structures, numbers shall be at least four inches (4") high. In the event any structure is too far away from the road to provide a clear view of the number posted on the structure, the responsible person shall erect a special posting at the entrance of the property.
