Only 40 units were begun in San Francisco compared with 75 a year ago. In Solano County, where prices are lower, 288 units were underway, up from 130 a year ago.

Aaron Stubblefield, Metrostudy’s regional director/senior consultant for Northern California, said that mortgage rates and prices were behind the slowdown. Mortgage rates increased by half a percent and home prices went up about $40,000 in the first half of 2018. Compared to 2017, housing starts in 2018 were up in the Bay Area.
