House numbers should be clear enough so that police, the fire department, paramedics, etc., can quickly locate properties in an emergency. Numbers are often the only way that first-responders can identify their intended destinations. Your city might even have laws requiring your house number to be of a certain size or color. Also, think of the poor pizza delivery guy who runs late because he can’t find your house, or frustrated party guests who have to knock on neighbors’ doors before they find yours.
Consider the following recommendations:
- The numbers should be large, within reason. Try to make them at least 5 or 6 inches tall. Smaller numbers may not be visible from the street if you have a large front yard. Replacement house numbers can be purchased from hardware stores and online.
- The numbers should be of a color that contrasts with their background. Reflective numbers are great because they are easier to see at night. Brown on black or white on yellow may look swanky but are bad choices for the purpose.
- Try not to put house numbers behind any trees, shrubs, or anything else that may obscure their view from the street.
- Make sure that the number faces the street that is listed in the house’s address. It does emergency workers no good if the house number faces a different street than the one the workers are traveling on.
- Is your house not visible from the road? Then the number should be placed at the driveway's entrance.
- The next time you hire an InterNACHI inspector, ask him whether your numbers are adequate. Inspectors should know the laws in your area and be able to offer you a professional opinion.
Even if your house number is currently adequate, InterNACHI believes that it might need adjustment in the future. The following are common reasons why you may need to adjust your number in the future:
- The addresses assigned to houses by the city occasionally change, and you must adjust your numbers accordingly.
- The trees or shrubs in front of your house have grown so much that the number is no longer visible.
- House numbers installed in the winter may be visible during that season, but become blocked by budding vegetation by spring or summer.
- Keep your numbers clean. They may not be reflective or contrasting if they are covered in mud.
- Trim back vegetation as needed.
- Don’t let piles of snow obscure the numbers. If this happens, raise the number so this situation does not happen again.
In summary, house numbers serve a critical function for emergency personnel and should be clearly displayed.
