On the House
Numbers may be placed on the house, but only if they are readily visible from the road (usually within 50 feet). The number should be posted so that it is visible from both directions of travel. Trees, bushes, or other debris should not block visibility from the road. Numbers should be placed near the front door within a radio of the porch light and above eye level. Avoid placing numbers away from the front door such as above garage doors.
Mailbox
Do not use your mailbox as the only means of identification for your home. If your mailbox is not in front of your house or near your driveway, emergency responders cannot locate you if you do not have your house number on your house or on a post or sign in your yard. Remember to mark your mailbox on both sides. Numbers on the mailbox door may be great for your mail carrier but are extremely difficult to see by drivers.
Address Signs
Numbers may be placed on a sign or post at the entrance to the right-of-way or shared driveway. One post, 39 inches to 40 inches high, shall be erected for a right-of-way or shared driveway serving more than one but less than three addresses and shall have if affixed to it address numbers to each house or unit served by that right-of-way or shared driveway. If the house or unit is not visible from the point at which the individual driveway breaks from the right-of-way or shared driveway, the address number must also be posted on the house or on an additional post must be erected at that point with the address number of that dwelling or unit. The address number should not be facing the road. The sign should be placed perpendicular to the road, so the number can be seen when traveling from either direction.
