Under Salt Lake County Ordinance 1849 § 11, 03-19-2019:
It shall be the duty of the addressing agency to establish an addressing standards and definitions policy for the county, to provide requested addressing guidance from the incorporated cities, to approve alphabetic street names and maintain and create address point data countywide by fostering a collaborative relationship with the incorporated cities of Salt Lake County. The addressing agency will maintain address points through documented data and/or validated data provided by the municipalities addressing authority.
Using the correct address allows emergency service responders to locate the caller in optimum time, USPS to deliver the mail appropriately, and the public to easily find a location in the Salt Lake Valley. Some of the Addressing Office’s responsibilities include street name approval, reviewing and implementing recorded documentation, maintaining property locations, and coordinating addressing standards with the municipalities in Salt Lake County.
