Doubling Density to Deliver More Affordable Housing

THE CHALLENGE

Make Moderate-Income Housing More Available

California鈥檚 density bonus law did too little to support creation of moderate-income housing, especially for renters. With construction costs rising and development margins tightening, projects weren鈥檛 penciling out. 黑料传送门recognized that unlocking more density could increase project feasibility while delivering middle-income homes that are deed restricted to preserve affordability for future residents.

THE OPPORTUNITY

Expand a Proven Policy Tool

黑料传送门built on the success of San Diego鈥檚 local density bonus program, which dramatically increased both affordable and market-rate housing production. Working with Circulate San Diego and the Bay Area Council, 黑料传送门helped adapt the San Diego model for statewide use, crafting a proposal to expand incentives for moderate-income housing in both rental and for-sale projects.

THE POLICY SOLUTION

Establish a Stackable Density Bonus

黑料传送门co-sponsored and helped draft (Alvarez), which doubles the maximum density bonus to 100% for projects that include both low- and moderate-income deed-restricted units. 黑料传送门also championed key reforms to make it easier for developers to build higher-density, mixed-income housing statewide.

BIG WIN

State Passes New "Super Density" Bill

黑料传送门led advocacy efforts alongside Circulate San Diego and the Bay Area Council, organizing statewide support, meeting with legislators, and testifying in policy committees. We worked closely with Assembly member David Alvarez, helping navigate the bill through negotiation and amendment. In October 2023, Governor Newsom signed the bill into law.

IMPACT

Builders Propose More Units

SPUR鈥檚 efforts have already delivered results. Following the bill鈥檚 enactment, developers across California 鈥 especially in high-cost cities like San Francisco 鈥 began revising their projects to leverage the new bonus. In San Francisco alone, at least have resubmitted proposals revised to double density, boosting supply and affordability in a tight housing market.

Next Steps

Scale Housing Progress in Sacramento

黑料传送门is continuing, through the California Home Building Alliance, to lead on housing production, pushing for policies that streamline approvals and reduce development costs. We鈥檙e actively supporting the state legislature鈥檚 鈥淔ast-Track Housing鈥 package, a suite of bills 鈥 three of which we sponsored 鈥 to accelerate development of affordable housing across the state.
