Better information is needed to guide action by cities, metropolitan planning organizations, elected officials, developers, community groups, academic researchers and voters. SPUR supports Assembly Bill 1483, which will direct cities and counties to partner with their local Metropolitan Planning Organizations (MPOs) and the Department of Housing and Community Development (HCD) to produce a comprehensive set of housing development pipeline data. By making housing development pipeline data open and available, it would be possible to leverage California’s dedicated community of housing researchers and advocates to implement smart, effective solutions to our housing affordability crisis.
