R1/R2 ASSOCIATED FIRE CODES LAFC 2014 ACCESS and EGRESS 505.1 Address identification. 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. These numbers shall contrast with their background. Where required by the fire code official, address numbers shall be provided in additional approved locations to facilitate emergency response. Address numbers shall be Arabic numbers or alphabetical letters. Numbers shall be a minimum of 4 inches (101.6 mm) high with a minimum stroke width of 0.5 inch (12.7 mm). Where access is by means of a private road and the building cannot be viewed from the public way, a monument, pole or other sign or means shall be used to identify the structure. Address numbers shall be maintained. 505.1.1 Size. Additional requirements of address size shall be as follows: 1. The height in inches of any number or letter therein shall be the sum of one-tenth (1/10) of the distance in feet of the number from the boundary of the property (upon which the building, structure, or parking lot is situated) butting the street, plus two (2), providing that every number shall not be less than 4 inches (100 mm) in height. 2. The overall width of any figure in or comprising the number or letter shall be one-half (1/2) of its height. The width of any portion of a figure in or comprising the number or letter shall be one-tenth (1/10) of its height. 505.1.2 Location. Design (including shape and style) as well as location of the street address numbers shall be such that they are legible and easily readable. Irrespective of whether the street address number was established before or after June 1, 1973, the Chief shall have the authority to prescribe a street address number larger in size than the dimensions stated in Section 505.1.1 when it is determined that due to lighting conditions, building location, shadows, background, or other reasons, street address numbers of minimum dimensions will not be easily readable from the street or approach to the entrance. A street address number of unusual design or placement may not be employed without prior written approval of the Chief. 506.1 Where required.
