State takes action on housing crisis as San Francisco's ambitious plan falls short.

Officials in Washington state and Vermont have banned single-family zoning to prevent a housing crisis like San Francisco's. Municipal and state efforts are underway to tackle the nationwide housing crunch, including mandating greater residential density and allowing duplexes to be built nearly anywhere. Democrats and Republicans alike are heeding the alarm bell and trying a range of policies to avoid San Francisco's fate, including housing, zoning, and land use reforms. The lack of affordable housing is a primary driver of eviction and homelessness in California, where 30% of the nation's homeless population lives.
