Associate Professor of Urban Planning and Public Policy Paavo Monkkonen was mentioned in a San Diego Union-Tribune opinion piece about the need to enforce housing regulations in San Diego. Every eight years, California cities are required to adopt a state-approved plan that includes rules about regional housing targets, sanctions and zoning restrictions. San Diego is currently out of compliance, but it is unclear how California’s Department of Housing and Community Development will enforce the rules. State law says that cities that lack a compliant housing plan forfeit authority to deny or downsize affordable housing projects. Monkkonen and his students studied San Diego’s housing plan and identified grave shortcomings. For example, they found that 65% of the sites San Diego identified for low-income and multifamily housing are located in the poorest third of the city’s neighborhoods, and the plan fails to open up neighborhoods reserved for single-family homes to multifamily housing.
