As part of our commitment to the education and professional development of UC Berkeley students, the Terner Center highlights exceptional student work that connects to our mission and research agenda. The analyses and policy proposals put forth in these projects may not be reflective of the official position of the Terner Center.
This piece is the second in a series to be released this summer by recent graduates of the City and Regional Planning and Public Policy graduate programs at UC Berkeley. The full report is available here.
Vacant Parcels in Oakland
Despite Oakland's high demand for housing, vacant parcels remain abundant throughout the city.
In the midst of a housing crisis fueled, in part, by lagging housing supply, vacant parcels represent part of the problem, as well as one part of potential solutions.
The Terner Center was recently invited to speak on a panel at SPUR to present and discuss my research mapping thousands of privately-owned vacant parcels in Oakland. Despite the city’s economic recovery since the recession, these parcels, typically empty except for grass or a paved surface, stubbornly persist throughout the city. When left in disorder, vacant parcels can negatively affect Oakland’s community, lowering quality of life,(1) health outcomes,(2)(3)(4) and home values.(5)(6) If developed, vacant land could serve as prime real estate for much-needed new housing. New developments would also increase Oakland’s property tax revenue, bolstering vital public services.
According to interviews with developers, brokers, and land use experts, parcels remain vacant for a number of reasons:
Physical characteristics such as location, shape, or environmental concerns may undermine a parcel’s desirability for potential buyers.
Owners may decide not to sell their parcel, instead choosing to wait for a higher price or to develop the parcel themselves. Land speculation is abetted by Proposition 13, which results in long-term landowners paying very low property taxes on their land.
Ownership itself may be complicated: the parcel may languish in a larger asset pool, or it may be owned by a number of individuals in a trust.
Newly instituted impact fees can deter future land transactions, as they cut into development funds that might otherwise go towards buying parcels. My analysis shows that the majority of vacant parcels are in Oakland’s Impact Fee Zone 1, the most expensive fee zone.
Vacant parcels are typically small, and are often located in residential neighborhoods.
An analysis of Alameda County Tax Assessor data reveals about 4,000 vacant, privately-owned parcels currently sitting unused across the city of Oakland. These parcels are typically small in size and located in residential neighborhood areas. City Council District 3 has the second highest number of parcels, normalized by the total number of parcels in the district. Close to five percent of both Community District 3 and 4’s privately-owned parcels are vacant.
Vacant Parcels in West Oakland
The use codes tracked by the Alameda County Tax Assessor’s Office illustrate that the vast majority of the vacant parcels are zoned for residential development, and 2,893 (or 71%) of the vacant lots are zoned for four units or fewer.
Unlocking vacant parcels should be a policy priority for Oakland.
In order to meet future demand, the city needs to permit 7,530 more units by 2023,(7) including 1,072 units affordable for households earning more than 120% of Area Median Income (AMI) and 2,804 units for households earning between 81% and 120% of AMI.(8) If an average of two units were built on each of the vacant parcels zoned for four units or less, Oakland would add close to 5,800 new residences. Oakland’s vacant parcels could accommodate a significant number of new housing units and increase tax revenue.
This past spring, Oakland City Councilmember Rebecca Kaplan proposed a special parcel tax on vacant properties. The proposed ordinance would tax parcels that are deemed vacant, a designation that includes both the vacant parcels described above as well as parcels with empty residential or nonresidential structures.(9) If approved by Oakland voters, the tax could act as a deterrent for speculation, and encourage owners of vacant parcels to sell or develop their land, ideally unlocking sites for housing. Whether or not the special parcel tax is approved, vacant parcels represent an untapped asset for the city, and Oakland should continue to investigate policy proposals that incentivize better use of empty land.
