The Halifax Regional Municipality By-law C-300, Respecting Civic Addressing, requires property owners to post their property assigned civic number on all structures or facilities. How to post your civic number: Post your house number so it is highly visible from the street day or night, 12 months a year. Post at the beginning of your driveway if your house is more than 100 ft. (30 m) from the road or hidden from view. The sign should be at least 48 inches (1.2m) from the ground to meet regulations. The minimum height of numerals on residential properties shall not be less than 4 inches. On non-residential properties, the minimum height of numerals shall not be less than 8 inches. The colour of the numerals shall clearly contrast with the background upon which the numbers are displayed.
