The addressing of properties and buildings is one of the most critical components of effective emergency response. LFRA, along with its partner municipalities, ensures that approved street names and building address numerals are consistent with standards and easy to recognize and use.

Proposed street names and numerals typically are reviewed and approved during the Planning process. In addition to LFRA and the municipality, addresses are reviewed by the Larimer Emergency Telephone Authority, which is the governing authority for 9-1-1 in Larimer County. LETA provides oversight to 9-1-1, and the equipment and the programs funded by LETA. Larimer County has five 9-1-1 call centers, 25 government entities, one State University and one National Park.


Address Size, Color and Location

New and existing buildings shall have approved address numbers, building numbers or approved building identification placed in a position that is plainly legible and visible from the street or road fronting the property.

The color of the numerals must contrast with their background. Address numbers shall be Arabic numerals.

Where the address is difficult to see due to building setback from the street or natural or manmade obstructions, additional numbers shall be displayed at the property entrance.

Address numbers may be required to be displayed on more than one side of the building, and the street name may need to be used, in addition to the numerals.

  • One- and two-family homes shall have minimum 4-inch high address numbers, with a minimum stroke width of I/2 inch. Individual suite or unit addresses in multi-family or commercial buildings shall be displayed with minimum 4-inch high numbers, with a minimum stroke width of I/2 inch.
