As the Bay Area endures profound demographic and economic shifts, many of its residents are working to understand their place within a changing urban environment. San Francisco, inundated with new, and mostly wealthy residents, is witnessing the emigration of many of its long-term residents to more affordable outlying areas. The East Bay, with its relatively close proximity to the city, and cheaper costs of living, has seen an influx of new residents in recent years, and is now facing shortcomings of its own in housing availability and affordability. While this problem will ultimately require certain large-scale interventions (like new multi-family housing developments) certain communities, including Berkeley and Oakland, have begun to loosen restrictions on Accessory Dwelling Units (ADU’s) (they are also called in-law units, or granny flats). ADU’s are a means of providing additional housing while maintaining the overall aesthetic of a traditional East Bay neighborhood. Karen Chapple, a professor of City and Regional Planning at UC Berkley has been an advocate for ADU’s, and working with students and colleagues at the Institute of Urban and Regional Development, has compiled convincing data for their overall positive impact within communities. Besides providing much needed housing for the community, ADU’s also offer many advantages for individual property owners – which make them a win, win proposition. For many, they can offer an extra source of income, adding value to one’s overall investment. Additionally, they have been recognized as an effective strategy for aging in place. With all of these things in mind, ADU’s are an intriguing proposition for any East Bay home owner.
