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.
