San Diego, November 27, 2025
UC San Diego’s study reveals that California’s SB 79 will enable denser development around La Jolla’s trolley stations. Signed by Governor Newsom, this legislation aims to alleviate the housing shortage by promoting multi-family housing near transit hubs. The law allows local governments to set development standards, with an expected implementation date of July 1, 2026. Key areas like UC San Diego Station and La Jolla Village Drive Station are poised for significant housing growth, which could enhance public transit access and drive economic development.
San Diego, California
UC San Diego’s Center for Housing Policy and Design (CHPD) has analyzed the potential impacts of California’s new state housing law, Senate Bill 79 (SB 79), on areas surrounding local trolley stations. The study identifies six locations in or near La Jolla that could experience significant changes due to the law’s provisions.
SB 79, signed into law by Governor Gavin Newsom on October 10, 2025, allows for denser development within a half-mile radius of major transit stations, including trolley stops. This legislation aims to facilitate the construction of multi-story, multi-family housing near transit hubs, thereby promoting public transit usage and addressing the state’s housing shortage.
As San Diego embraces innovation and entrepreneurship, SB 79 presents an opportunity for local business growth and residential development. By concentrating housing near transit, this law seeks to reduce commuting times, lessen traffic congestion, and promote community connectivity. This is a crucial step in addressing not only the housing crises in California but also enhancing the vitality of San Diego neighborhoods around trolley stations.
Potential Development Locations in La Jolla
The CHPD’s analysis highlights that the following trolley stations in or near La Jolla are eligible for mid-rise housing development under SB 79:
- UC San Diego Station
- La Jolla Village Drive Station
- Torrey Pines Station
- Genesee Avenue Station
- Clairemont Drive Station
- Balboa Avenue Station
These stations are part of the San Diego Trolley system, which qualifies under SB 79 due to its high-frequency service. The law permits local governments to allow housing projects of up to 55 feet in height and 80 units per acre within a half-mile of major transit stations with very frequent service. Projects within a quarter-mile are eligible for higher density.
Regulatory Flexibility and Local Controls
While SB 79 aims to streamline housing development near transit, it also grants cities the authority to set their own standards for these projects. This flexibility could foster entrepreneurial innovation as local leaders can tailor housing developments to meet the specific needs of their communities. However, it is essential to consider the implications of reduced local control over development zoning, especially since transit agencies such as the Metropolitan Transit System (MTS) and North County Transit District (NCTD) will also have zoning authority over land they own in these areas.
Expected Impact on Urban Landscape
With SB 79 set to take effect on July 1, 2026, its implementation is expected to significantly transform San Diego’s urban landscape, particularly in neighborhoods like La Jolla. Increasing housing density around trolley stations could enhance accessibility to public transit, drive local economic growth, and encourage small business development by attracting new residents and visitors. It represents a proactive approach to tackle California’s growing housing needs while facilitating convenience through sustainable transport solutions.
Conclusion
Senate Bill 79 illustrates a potential path forward for improving California’s housing landscape by encouraging denser and more organized community development around transit hubs. It empowers local governments while aiming to alleviate housing shortages in areas like La Jolla. By integrating housing with public transportation options, we can envision a future where San Diego remains a thriving hub for entrepreneurship and innovation. Residents and stakeholders are encouraged to stay engaged as the 2026 implementation date approaches, as their participation will be vital for maximizing the benefits of this impactful legislation.
