The Southern California Association of Non Profit Housing (SCANPH) researched 7 Southern California cities that have implemented IH (Brea, Irvine, Oxnard, Pasadena, Port Huemene, San Clemente, and Santa Paula) to get information about the productivity of their policies. We analyzed the inclusionary zoning codes for each of these cities, and spoke directly to city planners and local developers to get an in depth understanding of the specific planning, landuse, and political factors that influence the productivity of the inclusionary housing ordinance in each city.
