A $92 million ranch, know as Del Dios Ranch, hit the market in San Diego, making it the most expensive asking price for a residence in San Diego County, according to an article in Forbes by Erin Carlyle.  

The 210-acre property includes a Valencia orange grove and an 8,500-square-foot glass, redwood, and concrete home, the article stated.

From the article:

The estate, in the upscale San Diego enclave of Rancho Santa Fe, includes a four-bedroom main home and a one-bedroom guest home. The structures were built with northern California redwood, and the home’s marble floors lack grout. Though the home was built in the early 1970s, listing agent Linda Sansone described it as “soft Contemporary” for its walls of glass, concrete features, and marble floors.
