The Seattle City Council unanimously passed Mandatory Housing Affordability (MHA) upzones that allow higher density and impose affordable housing requirements on more than two dozen neighborhoods. This action upzones 27 neighborhood hubs, requiring developers in those areas to set aside 5 to 11 percent of their developments as affordable units or pay $5 to $32.75 per square foot in fees. It also allows for denser housing on about 6 percent of lots where new construction is currently reserved exclusively for single-family homes and upzones by one or several stories blocks where apartment buildings and commercial buildings are already allowed. Along with the upzoning legislation, the council passed a resolution that commits the city to consider other steps, such monitoring and combating the displacement of marginalized communities. City officials estimate the upzones will create up to 3,000 affordable units across Seattle over the next decade.
