Berkeley may eliminate single-family zoning in neighborhoods like this one on Hillegass Avenue in The Elmwood. Photo: Frances Dinkelspiel The future of Berkeley could be denser and less segregated, thanks to new proposals to scrap historically racist single-family zoning and legalize the widespread construction of fourplexes. On Feb. 23, the City Council will vote on a resolution that could start a process to eliminate “exclusionary zoning” – typically viewed as the R1 or single-family-only zones that predominate in richer, whiter neighborhoods in North and Southeast Berkeley, by December 2022. Separately, the council and the mayor are considering allowing multiplexes in places zoned for single families, potentially opening the door for residents of more-diverse socioeconomic backgrounds.
