Happ knows all about this since he lives in one of the few true zone 11 areas in SoCal. It's not like it's hot and tropical in these areas, they just have a sweet spot, usually with excellent canyon cold air drainage, and they just don't usually drop below that 40 F mark. I think the southern side of the Santa Monica Mtns. from Topanga, eastward over to the Ghetty Center, and continuing along Sunset Blvd towards the Hollywood Hills is the largest zone 11 in CA. I bet Mt. Miguel in SD County and the top of Cowels Mtn. and Mt. Helix are close to a zone 11 also.

I was doing a tour of a garden outside of Summerland, California the other weekend. The caretaker said that he had put a few weather units that recorded the coldest temperature of an entire year. He positioned one in the wash area, and another a few hundred feet up the way on a hill. The wash measured 30 whereas the hill area measured 45.
This is coastal California though. I am pretty sure that Santa Barbara's foothills are all frost-free. I call it the Plumeria belt, because it's the only place in town where people can actually grow nice-looking plumerias. I believe that's a good indicator for the sort of climate I'm looking for.
Do these frost-free climates exist in inland areas where real estate is cheap? The coast is more for tourists who have wet dreams about California, who don't know any better, and come here in shorts and T-shirts only to shiver in our thick marine layer.

The above link is a map that identifies various climate zones for California. The Santa Monica mountains from Malibu to the Hollywood Hills is designated USDA 11. Actually it extends well east to near Pasadena and down the foothills to around Montebello\ Pico Rivera. Also San Diego bay northward to Encinitas. But zone 11 in southern California merely means frost-free. A common characteristic for this micro-climate is elevation above a basin, the ocean, canyon; south-facing foothills and diurnal winds\ night winds; good drainage and air mixing. For example the orange groves in San Joaquin valley are planted in the foothills on either side of the Central Valley; it isn't zone 11 but shows where drainage allows for sensitive citrus. The avocado and even macadamia groves in San Diego county are almost all located in the foothills. I have asked old timers who live on the same road as me if they have ever witnessed frost; after a long pulse they invariably admit that they can never recall a time where frost occurred in this hills. But even lowland areas such as where the official weather stations in Los Angeles\USC and San Diego\Lindbergh Field are located did not record minimums below freezing during the last two Arctic outbreaks in 1990 and 2007 and both are in zone 10. Even parts of San Francisco are frost-free.
But, as we know, being frost-free doesn't mean these California areas have anything else in common with other USDA zone 11 regions such as Miami, Honolulu or Baja California. Without the high humidity\ summer rainfall, very warm nights even in winter and often dry winters we cannot grow the classic palm of zone 11; coconuts!
