Paavo Monkkonen, associate professor of urban planning and public policy, spoke to the San Francisco Chronicle about a new housing development in a wealthy Bay Area suburb. A multi-family housing development will be built in the city of Danville, creating 144 new units, 11 of which are to be set aside for affordable housing. The apartment building will accommodate lower-income people in the local workforce as well as middle-class residents priced out of most Bay Area real estate. Some cities say this type of multi-unit development is not feasible because they are built-out, with no more land available to develop. Monkkonen argued that suburbs use that as an excuse to not create more housing. “What they don’t tell you is that up to 90% of their land is zoned for single-family homes,” he said. If changing that “is not on the table, things aren’t going to change.”
