Why are house numbers so important?
House numbers are the means by which emergency responders identify your house in the event of an emergency and are required by law. In the event of a fire we might see the smoke or fire, but if you need police or emergency medical assistance it will take much longer to identify your house if there are no house numbers present. Also, we have to be able to identify your house in the day-time, night-time and in all different weather situations. House numbers should be a minimum of three inches in height, posted on the house and a contrasting color to the house. If you cannot easily see the numbers on the house from the street, another set of numbers needs to be posted at the street, usually on a mailbox or a post.
