How SB 79 is forcing California cities to upzone near transit stops
A new state law overrides local zoning within a half-mile of transit stops, and cities from Beverly Hills to San Jose scrambled to meet its July 2026 deadline.
For decades, a city council could decide how tall a building could rise near a train station. Senate Bill 79 changes that calculus for much of California. Signed by Governor Gavin Newsom on October 10, 2025, the law tells cities in the state's most transit-heavy counties that they must allow multifamily housing, by right, on land within a half-mile of qualifying transit stops — no matter what the local zoning code says.
The law's effective date, July 1, 2026, has already passed, and the months around it have turned into a scramble. Some cities embraced the new density. Others tried to shrink it, delay it, or steer it away from single-family blocks. For property owners, developers and homebuyers near a rail or bus rapid transit stop, the outcome of that scramble now shapes what can legally be built next door.
What SB 79 actually requires
SB 79 applies only in "urban transit counties" — those with more than 15 passenger rail stations. That covers eight counties: Los Angeles, Orange, San Diego, Sacramento, Alameda, Santa Clara, San Francisco and San Mateo. Within those counties, any site zoned for residential, mixed-use or commercial use near a qualifying stop becomes eligible for a "transit-oriented housing development" of at least five units.
The law sets two tiers of transit stops. Tier 1 covers heavy rail and very-high-frequency commuter rail; Tier 2 covers light rail, high-frequency commuter rail and qualifying bus service. Within a quarter-mile of a Tier 1 stop, cities must allow buildings of at least 75 feet and 120 units per acre. Between a quarter-mile and half-mile, the minimum drops to 65 feet and 100 units per acre. Tier 2 stops carry lower minimums: 65 feet within a quarter-mile, and 55 feet in the outer band. Projects must set aside a share of units as affordable — 7% for extremely low-income tenants, 10% for very low-income, or 13% for lower-income — kept affordable for 55 years for rentals or 45 years for ownership units. Hotels are excluded, and buildings above 85 feet require a skilled and trained workforce.
Why the July 2026 deadline matters
The law technically took effect statewide on July 1, 2026, but cities aren't required to simply accept the state's default numbers. They can adopt their own implementing ordinance, or a more customized "local TOD alternative plan," as long as it matches or exceeds SB 79's overall zoned capacity. A draft must go to the state Department of Housing and Community Development 14 days before adoption, and the final version within 60 days of enactment. HCD then has 90 days, plus a possible 30-day extension, to review it for compliance; if it finds problems, the city gets 60 days to respond.
A second deadline looms behind the first. Starting January 1, 2027, if a city denies a qualifying transit-oriented project in a "high-resource" area, state law presumes that denial violates the Housing Accountability Act and makes the city immediately liable for penalties — unless it can show a genuine health, life or safety reason for the denial. That turns SB 79 from a zoning mandate into something enforceable through housing lawsuits.
Beverly Hills: opposition, then a redirected plan
Beverly Hills fought SB 79 from the start. In a June 2025 letter to the Assembly Housing Committee, Mayor Sharona Nazarian wrote that the bill would let projects near transit reach heights of up to 75 feet and densities of up to 120 units per acre, bypassing the city's adopted general plan without guaranteeing that any housing — let alone affordable housing — actually gets built. The letter also flagged that transit agencies could adopt their own development standards for property they own or control — "even for projects that are entirely commercial" — separate from city review.
The bill passed anyway, and Beverly Hills turned to the law's alternative-plan option. Its draft plan calculated SB 79's baseline zoned capacity in the city's transit zones at roughly 22,485 housing units, and proposed cutting that to about 19,550 units — a reduction of nearly 2,935 units, achieved mainly by halving density on single-family-zoned "exporter" sites and shifting that capacity toward denser commercial parcels along Wilshire Boulevard, a mechanism the law allows called adjacency-based redistribution. California YIMBY, which tracks the law statewide, characterized the plan as removing roughly 15% of the city's mandated capacity. HCD rejected the city's first version of the plan on May 8, 2026; the Beverly Hills City Council adopted an amended version on June 9, 2026 and resubmitted it for state review.
San Jose: big exemptions, a tenfold jump at one station
San Jose's transit network puts 56 stops — served by Caltrain, BART, VTA light rail and bus rapid transit — inside the law's reach. City staff estimates illustrate how sharply the standards can change a neighborhood's zoned capacity: at Snell Station, current zoning allows about 3,200 homes, but SB 79's minimums would raise that to roughly 37,000 units.
Rather than accept that scale everywhere, the City Council directed staff to permanently exempt about 6,600 acres of industrial land, mostly in North San Jose, across six areas: North San Jose, Old Edenvale, the Monterey Business Corridor, East Gish, Mabury and the Berryessa International Business Park. Mayor Matt Mahan noted that land dedicated to employment uses is a relatively small share of the city, around 13%, while Vice Mayor Pam Foley was blunter about the process, calling the situation "a mess." SB 79 permits this kind of industrial carve-out only in jurisdictions with at least 15 qualifying transit stops, a threshold San Jose clears easily.
“The law's effective date, July 1, 2026, has already passed, and the months around it have turned into a scramble.”
A patchwork response across the state
Other cities have taken very different paths. Sacramento and Berkeley applied the law's default standards without carving out deferrals. Oakland and Menlo Park council members went further, proactively removing exemptions in their own jurisdictions to speed up housing near transit. Los Angeles instead pursued what CalMatters described as a strategy of "maximum delay," voting to allow three- to four-story buildings in higher-income neighborhoods to hit the 50% density threshold that qualifies a site for a later compliance deadline; Councilmember Katy Yaroslavsky said the approach "adds meaningful housing capacity now and gives us time to decide" on future density. San Francisco has been weighing its own exemptions for industrial and low-resource areas alongside a separate rezoning effort tied to Mayor Daniel Lurie's Family Zoning Plan.
Palo Alto tried to use a provision allowing Bay Area jurisdictions more time to adopt permanent plans as grounds for an emergency ordinance halving density and height, but the effort stalled after pro-housing groups threatened legal action and Councilwoman Julie Lythcott-Haims said she found "no evidence presented" to support declaring an emergency. In the two weeks after July 1, developers filed nine multifamily applications in Palo Alto proposing 341 units, most clustered near its downtown and California Avenue Caltrain stations. California YIMBY's early tracking also flagged Burlingame for placing zoned capacity on sites such as schools and parks that the group says will never be redeveloped, Oceanside for declaring large areas "unwalkable" to avoid triggering the law, and Burbank for moving to cancel a planned bus rapid transit line that would have brought more land under SB 79's reach — though these are characterizations from an advocacy group pushing for the law's full implementation, not findings from a court or regulator.
What it means for owners, buyers and developers
SB 79 does not force any current owner to redevelop. It changes what is legally allowed on a parcel, not what an owner must do with it. For someone selling a lot near a rail or bus rapid transit stop, though, the zoned capacity underneath that lot may have jumped sharply since last year, which can affect what a builder is willing to pay for it. For homebuyers, the practical question is which version of the rules applies on a given block: the state's default standards, a city's own implementing ordinance, or an alternative plan still being negotiated with HCD — and in cities like Beverly Hills, that answer was still moving as of publication.
Developers face a similarly unsettled picture. A project that qualifies as a transit-oriented housing development can also access the streamlined, ministerial approval process under SB 35, avoiding a full CEQA review — but only if it fits within whatever standards ultimately survive HCD's scrutiny. Given how much cities' plans have shifted in just the months since July, anyone evaluating a parcel near a covered transit stop should check current zoning directly with the local planning department rather than assume last year's rules, or even the state's published defaults, still apply.
