A: Signs/numbers should be at least two inches high, mounted at the end of the driveway (on a tree or pole), between 36 and 48 inches from the ground (above most snow depths) and be reflective (to be seen with a flashlight at night). Residents in homes that still display the old four digit fire numbers (not the address) should remove those since that numbering system is no longer used. The fire department only uses street addresses. It's important to remember that many houses in the community have access issues, are poorly lit at night and can be hard to find. A highly visible sign will assist in a more rapid response.
