After spotting an open lot east of downtown Sacramento, Erica Bergsma, a local developer of multifamily infill housing, knew that it would be a great place to build a house for her own family. “I stalked it for three years,” says Bergsma, who was then living in the suburban outskirts of the city. The 32-by-80-foot parcel was located at the threshold between a lively commercial area and a historical residential district—in walking distance of shops and restaurants. Bergsma also knew who could help her tackle building on the challenging infill site.
