Transform Unused Excess Land Into Affordable Housing

Partner with experienced developer to build win for cities and community groups

Open land zoned for housing is not an easy thing to come by in California – even amidst an ongoing housing crisis. Given competing interests, any measure of open land is quickly fought over by various parties debating its plotted usage and potential development. It can all too quickly devolve into an endless standoff or a heated dispute between city representatives and members of the community.

A rather notable change to open land regulation has shifted things in California, however – excess land in particular. Excess land refers to land owned by a government agency that is no longer used for the agency’s respective operations. Although Jamboree has utilized excess land to develop affordable housing for years, recent state legislation has prioritized the development of affordable housing on these sites – and Jamboree has the knowledge, experience, and resources to partner with cities to execute these projects with the support of the community.

How does the Surplus Land Act impact cities?

In 2019, Governor Gavin Newsom strengthened California’s Surplus Land Act with AB-1486, a law that essentially created stronger reporting requirements in regard to excess land and implemented a minimum number of affordable housing units to be met. This inherently increased the competitiveness of projects built upon public land.

The Surplus Land Act’s AB-1486 introduced these rules for California:

  • Cities must notify qualified housing developers of available public land.
  • Municipalities must negotiate exclusively with the entity proposing the most affordable housing units.
  • Any time excess land is used for housing of any kind, at least 15% must be set aside for affordable housing.

While land development has the potential to be a costly mistake in this new era, in fiscal terms as well as public opinion, Jamboree’s expertise in navigating the Surplus Land Act’s affordable housing requirements delivers a win-win for both cities and communities.

How can Jamboree ensure that community groups are a part of city development?

With each affordable housing development, Jamboree is steadfastly committed to involving the community in project planning, evaluation, delivery, and management. As a leading nonprofit affordable housing developer, Jamboree relies on community outreach to bring about community impact. Jamboree's goal is to advance each community's well-being through a communal sense of security, strengthened social bonds, improved educational outcomes, and access to parks and recreational facilities as well as physical and mental health services.

Development happens quickly and it can sometimes prove challenging to engage city officials as an outside group. Jamboree is able to work alongside cities as they develop excess land for affordable housing and ensure that community groups are part of the plan. We recognize a simple truth: that the most successful developers are the ones that listen to the community from the start and commit to ongoing communication well after the construction site has been cleared away.
