California Will Let Builders Put Apartments Next to Train Stations Starting 2026

New Law Overrides Local Zoning Rules

California just made it legal to build apartment buildings up to seven stories tall within half a mile of major transit stops.

Governor Gavin Newsom signed Senate Bill 79 in October 2025, and it takes effect July 1, 2026.

The law applies to eight of the state’s most populated counties, where millions of residents have been priced out of housing near the trains and buses they paid for with their taxes.

Senator Scott Wiener tried for seven years to pass this kind of law.

He finally succeeded, but not everyone is happy about it, and some cities are already looking for ways around it.

Eight Counties Face New Rules

The law targets counties with 15 or more passenger rail stations: Los Angeles, Orange, San Diego, Sacramento, San Francisco, Alameda, San Mateo, and Santa Clara.

Together, these counties hold the majority of California’s population and most of its transit infrastructure.

Within these areas, developers can now build denser housing on any residential, commercial, or mixed-use lot within a half mile of qualifying transit stops.

Local zoning that previously blocked apartments in these areas no longer applies.

Wiener Failed Four Times First

Senator Scott Wiener, a San Francisco Democrat, first introduced transit-housing legislation in January 2018 as Senate Bill 827. That bill died in committee.

He tried again in 2019 and 2020 with SB 50, which failed on the Senate floor. A lighter version, SB 902, passed the Senate but died in the Assembly.

SB 79 finally broke through in 2025, passing the Senate 21-13 in June and clearing the Assembly in September. The bill’s passage marked the biggest state-level zoning change in California history.

A 3 Million Home Shortage

California needs about 3 million more housing units than it has. The shortage has been building for decades as the state added jobs faster than homes.

Average rent now sits around $2,770 per month, roughly $670 higher than the national average.

To qualify for a mortgage on a mid-tier California home, a household needs to earn about $221,000 per year, more than double the state’s median income.

About 37 percent of Californians have seriously considered leaving because of housing costs.

Most Land Bans Apartments Already

In Los Angeles, more than 70 percent of residential land is zoned exclusively for single-family homes.

Many of these neighborhoods sit right next to rail stations where billions of tax dollars have been spent on transit infrastructure.

The same pattern holds across Southern California, where nearly 80 percent of residential land in the region is restricted to single-family housing.

SB 79 changes this by automatically allowing denser development near transit, regardless of what local rules say.

Two Tiers of Transit Stops

The law creates two categories based on transit quality. Tier 1 includes heavy rail and high-frequency commuter rail like BART and Caltrain.

Near these stops, buildings can go up to 95 feet tall with density of at least 30 units per acre. Tier 2 covers light rail and rapid bus lines.

These areas allow shorter buildings but still permit significantly more density than single-family zoning. The closer a lot sits to a station, the taller the allowed building.

Affordable Units Are Required

Projects with more than ten units must set aside a percentage for lower-income households.

The exact requirement depends on income level: 7 percent for extremely low income, 10 percent for very low income, or 13 percent for low income.

These affordability restrictions last 55 years for units that are sold and 45 years for rentals. If a city already has stricter affordability rules, those local requirements still apply.

The law also bans demolition of rent-controlled housing.

Transit Systems Are Going Broke

California’s transit agencies are in serious financial trouble. Statewide ridership in 2023 was 29 percent lower than in 2019.

BART’s weekday ridership sits at about 45 percent of pre-pandemic levels.

The four largest Bay Area operators face combined annual deficits exceeding $800 million starting in fiscal year 2026. BART alone has a $380 million gap, equal to 35 percent of its operating budget.

Supporters of SB 79 argue that building housing near stations will bring riders back and stabilize agency finances.

Hong Kong Makes Money This Way

Hong Kong’s Mass Transit Railway is one of the few profitable public transit systems in the world.

It generated $1.5 billion in profit in 2014 alone. The secret is its Rail Plus Property model, where the transit agency develops housing and commercial space around stations and keeps the revenue.

More than half of the railway’s income comes from property development rather than fares.

California lawmakers cited Hong Kong as a model, hoping that more housing near stations will eventually help fund transit operations here.

Cities Say They Lost Control

Local governments pushed back hard against SB 79. Los Angeles and San Diego both formally opposed the bill.

Critics say it strips cities of their ability to shape their own neighborhoods and could change the character of single-family areas. Some homeowners worry about property values and increased traffic.

The law does allow cities to create alternative plans that achieve the same overall housing capacity, but these plans must be approved by the state Department of Housing and Community Development.

Some Cities Are Fighting Transit

In Burbank, opponents of new housing have found a creative workaround: fight the transit itself.

If a bus line loses its dedicated lane or a rail project gets delayed, it might not qualify as a major transit stop under SB 79. That would exempt surrounding areas from the automatic zoning changes.

Researchers warn this creates perverse incentives where cities might actually work to downgrade their own transit service to avoid triggering housing requirements.

The law’s authors anticipated this and limited eligibility to projects already in regional transportation plans.

Enforcement Starts July 2026

The California Department of Housing and Community Development will oversee compliance. Cities that fail to follow SB 79 can have their local ordinances suspended.

The state attorney general can also step in and levy fines of $10,000 to $50,000 per month until a city complies.

Local governments have until the law takes effect to either implement it directly or submit alternative plans. For buildings over 85 feet, developers must pay union-level wages or hire skilled and trained workers.
