Unincorporated Los Angeles County


Los Angeles County covers 4,000 square miles and is home to a population of 9.5 million individuals; this population is anticipated to grow to 11.5 million by 2020. The unincorporated areas include more than 2,600 square miles, represent two-thirds of the County’s land and one-tenth of its population. There are approximately 120-125 UNINCORPORATED areas (depending on how you define them), some of the unincorporated areas are as small as a few blocks, some are urban centers with more than 150,000 residents and some, with sparse populations, cover hundreds of square miles in the high desert. If they comprised a single city, the UNINCORPORATED areas would be the third most populous in the State, after Los Angeles and San Diego. The UNINCORPORATED areas are both socially and economically diverse.

Is the property in question located within the UNINCORPORATED area of the County?
