In the Bay Area, roughly 85 percent of residential neighborhoods (49 percent in Berkeley) are zoned single-family-only, according to UC Berkeley’s Othering and Belonging Institute. “That’s ridiculous,” said Stephen Menendian, the institute’s assistant director and director of research. “The fact that only 15 percent of residential areas permit by zoning ordinance denser housing options, in a region that is the economic vanguard of the country, is totally inadequate to the needs of the region and frankly the country.”
