In California, there has been a growing concern about rising housing cost burdens. Declining housing affordability, particularly in job-rich areas, can lead to lengthy commutes and pose significant challenges to achieving sustainable transportation and development patterns. It may also cause disproportionate impacts on vulnerable population groups by pushing members of these group to areas where jobs and other amenities are limited. Although no single factor can fully explain the rise of this critical issue, local growth control measures (e.g., growth moratoriums, density restrictions, and public facilities requirements) and other strict land use regulations have been criticized for constraining the housing supply and adding to jobs-housing imbalances. It is important to understand what motivates local growth control actions, as well as how these controls may affect land use, housing, and transportation.

California’s legislature has attempted to address the state’s housing affordability crisis in recent years by adopting numerous laws encouraging new development in transit-accessible and/or jobs-rich areas, but the evidence concerning the impacts of these laws on housing development remains largely anecdotal. In particular, policymakers lack adequate information concerning: (1) the types of neighborhoods where developers are more likely to build; and (2) the causes of delays in approvals for proposed projects in jobs-rich and transit-accessible areas. In new research, scholars from UC Irvine and UC Berkeley address this problem by drawing on a unique project-level dataset, the Comprehensive Assessment of Land Use Entitlements (CALES), to analyze development projects including five or more residential units that were approved for development from 2014 through 2017 in six cities: Inglewood, Long Beach, Los Angeles, Pasadena, Redondo Beach, and Santa Monica.

Recent state legislation addresses California’s housing affordability crisis by encouraging new development in transitaccessible and/or jobs-rich areas. But policymakers lack key information about the effects of laws and plans on developers’ decisions about whether and where to build housing, and factors contributing to delays in receiving government development approvals in target areas. Drawing on a unique dataset detailing all residential projects of five units or more that were approved from 2014 through 2017 in selected California jurisdictions, this project analyzes how project attributes and transportation-related factors affected infill housing construction. We find that in cities with extensive transit infrastructure, new projects were generally located in parts of the city with high proximity to transit, but that proximity to rail stops or high frequency bus stops was not associated with extreme delays in project approval compared to all projects in general. The only factors related to extreme delay are the percentage of land within a half mile radius of dedicated single-family housing and whether a multiunit project required a rezoning or general plan amendment, the latter of which is associated with 326% increase in the odds of a project being extremely delayed. Our findings suggest that cities could expedite transit-accessible housing development by ensuring that general plans and zoning accommodate multifamily development near transit.
