LA County’s Unified House Numbering System

la county unified house numberingAfter 11 years in the County, and many years dealing with addresses, I just learned about our Unified House Numbering System guidelines, which points to all of the relevant source information that we use to assign house numbers in the Unincorporated portion of the county.  Many cities were incorporated after this was adopted in the 1920’s the history here is great!

Here is the document – great job DPW!!!:  House Numbering and Street Naming Material – 2013

I especially liked the definitions of the various street name prefixes and suffixes, and classifications by widths, where streets 100 feet wide and up are either Boulevards, Highways, and Parkways!
