Our final stop is the most expensive place to live in the United States. Right outside Los Angeles in the incorporated town of Bradbury, Calif., is ZIP code 91008. But don't tell the postman.
According to the United States Postal Service, 91008 is officially listed as Duarte. But the homes selling for $4.2 million and more are primarily in Bradbury [source: Forbes]. In fact, the 91010 ZIP code covers the majority of Duarte. Tiny Bradbury, encompassing 1.9 square miles (5 square kilometers), sits in the foothills of the San Gabriel Mountains, bordering the sprawling Angeles National Forest. Home to about 1,000, almost all of Bradbury is zoned agricultural, and many of the most expensive houses are within two gated communities [source: City of Bradbury].
So if you suddenly find yourself a multi-millionaire overnight, head east and a little north out of downtown L.A. You should be home in about 20 minutes.
