Berkeley’s zoning code was amended to eliminate all single-family zones and replace them with multi-family zones, allowing for development of duplexes, triplexes, and fourplexes to alleviate the city’s housing strain. This is estimated to add an additional 9,000 housing units in the next several years. Berkeley was nationally known for being the “birthplace of exclusionary zoning,” and the town decided it was time to address the issue. The new units will match existing neighborhood style while also maintaining historic character.
