"Eichler" has become a household word these days, used to describe just about any modernist tract house. Sort of the way "Eames" is used on eBay as a catch-all for any object remotely modern that looks like it may have been made sometime in the 50s or 60s. But actually, there are very few Eichler developments in Southern California. That was more of a Northern California thing, and there are many tracts around the Bay Area. In SoCal, there are only four: three in Orange County and one two in the Valley.
