Developers have lined-up to build high-density builder's remedy housing in some of the toniest Zip Codes in the Bay Area, bedroom communities where every home fetches prices well in excess of $1M.

Since California invoked its builder's penalty remedy for cities that failed to file approved plans to develop new housing—which permits affordable housing developers to bypass local zoning officials—more than 34 project plans totaling more than 6,400 units have been filed in 11 cities, according to a Bay Area News Group survey.

The projects include eight-story condos that will be perched over houses in Los Altos Hills as well as 150 units on a hillside in rural Marin County. Many of the projects target affluent areas that have long resisted large housing projects, the San Jose Mercury News reported.
