Los Angeles County, California
Los Angeles County is the most populous county in the United States, a 4,000-square-mile market running from the Antelope Valley over the mountains to the ports of Los Angeles and Long Beach and out to Santa Catalina. Eighty-eight cities plus vast unincorporated territory mean entitlement rules change block to block, and transit-oriented density bonuses, hillside and fire-zone limits, and the ports' logistics demand drive most of what gets built.
