San Diego City Council is set to vote in June on significant changes to the ADU (Accessory Dwelling Unit) bonus program, a pivotal housing policy initiated in 2019. The program, which allows property owners to build multiple additional units beyond state limits in exchange for affordable rent restrictions, has sparked intense debate. Mayor Todd Gloria’s proposed reforms aim to tighten restrictions, especially in affluent, low-density neighborhoods, drawing sharp criticism for potentially reducing affordable housing in the city’s most resource-rich areas.

Purpose of ADU Bonus

San Diego’s ADU bonus program, launched in 2019 under former Mayor Kevin Faulconer, incentivizes homeowners to build at least four additional units—double the two allowed by state law—if one unit is deed-restricted for affordable rent. Proximity to public transit permits even more units, subject to zoning limits like lot size and height restrictions.

Neighborhood Backlash and Concerns

Communities such as Clairemont, Encanto, and Kensington have voiced strong opposition, arguing that large ADU developments threaten neighborhood character. Residents fear that increased density and scale of these bonus projects disrupt established community aesthetics and lifestyles.

Mayor Gloria’s Proposed Rollback

Responding to the backlash, Mayor Todd Gloria proposes new fees, mandatory parking requirements, wildfire hazard zone restrictions, and a complete elimination of the ADU bonus program in neighborhoods zoned for very low density. This includes some of San Diego’s wealthiest and most exclusive neighborhoods.

Impact on Housing Equity

A KPBS analysis reveals that 87% of the land targeted for elimination under Gloria’s plan is classified as high- or highest-resource on California’s “Opportunity Map,” which tracks neighborhood wealth, school quality, environmental conditions, and economic access. Restricting ADU construction here could limit affordable housing in areas where residents enjoy the best opportunities, potentially undermining equitable housing goals.

Historical Context of Segregation

San Diego’s policy decisions occur within the framework of “affirmatively furthering fair housing” — a state mandate requiring proactive correction of past discriminatory housing practices like redlining and racially restrictive zoning. The city’s “racially concentrated areas of affluence” map shows that roughly 25% of these privileged, predominantly white neighborhoods would lose ADU bonus eligibility, raising concerns about perpetuating “opportunity hoarding.”

Official Perspectives and Defense

Peter Kelly, San Diego City Planning Department spokesperson, emphasized, “All of the city’s housing efforts are intentionally focused on increasing affordable housing opportunities in all neighborhoods, particularly in high-resource areas,” and noted that 78% of zones remaining in the program are in moderate to highest resource areas. He also cautioned against judging fair housing by a single optional bonus program alone, highlighting recent capacity increases in high-resource neighborhoods through other planning initiatives.

Community Voices and Future Outlook

Councilmember Kent Lee, chair of the Land Use and Housing Committee, said, “Accessory dwelling units can be the entry point a family needs to gain access to a great community, and we shouldn’t lose sight of that,” urging the council to fix program issues without creating new ones. Critics like Danna Givot of Neighbors for a Better San Diego argue the analysis overstates exclusion impacts, noting most ADUs are built near transit in lower-resource areas. In contrast, Saad Asad of YIMBY Democrats warned, “These maps show the new ADU proposal would protect wealthy enclaves and expect less-resourced communities to solve our housing shortage,” adding that restricting homes in good-school areas could worsen traffic and housing costs citywide.
