Another approach is to establish regional planning with mandatory housing targets. California has a state-mandated process, the Regional Housing Need Allocation (RHNA), to identify the total number of housing units (by affordability level) that each jurisdiction must accommodate in its Housing Element. For example, the California Department of Housing and Community Development (HCD) has identified the total housing need for the San Francisco Bay Area for an eight-year period (in this cycle, from 2014 to 2022). The regional association of governments must then develop a methodology to distribute this need to local governments in a manner that is consistent with a specified development pattern. Local governments in theory must revise their housing plans to allow their markets to accommodate their portion of the region’s housing need.
