SB 79: California’s New Transit-Oriented Development Law Explained
What It Means for Property Owners, Builders, and Developers
When most people think about California’s housing shortage, they think about rising home prices or the lack of affordable housing. State lawmakers, however, see another challenge: many of California’s busiest transit systems are surrounded by neighborhoods where housing density is far lower than the available infrastructure can support.
SB 79 is California’s latest attempt to address that problem.
Known as the Abundant and Affordable Homes Near Transit Act, SB 79 allows significantly more housing to be built near qualifying transit stops by overriding certain local zoning restrictions. The law is designed to encourage higher-density housing where people can more easily walk, bike, or use public transportation instead of relying on a car. SB 79 was signed into law in October 2025 and took effect on July 1, 2026.
While this may sound like another housing bill aimed at major cities, it represents a much larger shift in California’s approach to land use planning.
What Is Transit-Oriented Development?
Transit-Oriented Development (TOD) is exactly what it sounds like.
It encourages housing and mixed-use development within walking distance of high-quality public transit, such as:
· Heavy rail stations
· Light rail stations
· Commuter rail stations
· Bus Rapid Transit (BRT) corridors
The idea is simple.
If people can live closer to transit, they may drive less, reducing traffic, greenhouse gas emissions, and infrastructure costs while making better use of existing public investments.
Why Did California Pass SB 79?
California has invested billions of dollars in public transportation.
Yet many transit stations remain surrounded by low-density development.
Lawmakers concluded that this limits both housing production and transit ridership.
Rather than expanding outward into undeveloped areas, SB 79 encourages communities to grow around infrastructure that already exists.
The Legislature believes this approach can:
· Increase housing production.
· Improve transit ridership.
· Reduce commuting distances.
· Make better use of existing public infrastructure.
· Support more walkable communities.
What Does SB 79 Do?
SB 79 requires qualifying housing developments near certain transit stops to be allowed on sites already zoned for residential, mixed-use, or even commercial development within designated urban transit counties. It also establishes minimum density and height standards based on the type and frequency of nearby transit service.
In practical terms, the law may allow:
· Taller buildings.
· Greater residential density.
· More multifamily housing.
· Housing on some commercially zoned properties.
Exactly what is allowed depends on:
· The type of transit.
· Distance from the transit stop.
· Service frequency.
· The specific requirements of SB 79.
Does SB 79 Apply Everywhere?
No.
This is probably the biggest misconception about the law.
SB 79 primarily applies within urban transit counties that contain qualifying rail and rapid transit systems.
Many rural counties—including Mendocino, Humboldt, Trinity, Modoc, Lassen, and others—are generally not directly affected because they do not have the qualifying transit infrastructure required under the law.
Why Should Rural Property Owners Care?
At first glance, many people in rural California might assume this law has nothing to do with them.
But statewide housing legislation often influences future policy.
SB 79 reflects a broader trend in California planning:
The State is becoming increasingly willing to override local zoning restrictions when housing production is considered a statewide concern.
Whether future legislation focuses on transit, workforce housing, wildfire recovery, or another issue, SB 79 demonstrates that the balance between state and local land use authority continues to evolve.
Understanding that trend is valuable, even if your property is outside a qualifying transit area.
What About Local Control?
One of the most debated aspects of SB 79 is its impact on local zoning authority.
Historically, cities and counties decided:
· Building heights.
· Residential density.
· Permitted land uses.
· Development intensity.
SB 79 limits some of that discretion near qualifying transit by establishing statewide development standards that local governments must follow unless they adopt an HCD-compliant alternative plan.
Supporters argue this is necessary to address California’s housing shortage.
Opponents argue it reduces local control over neighborhood planning.
Regardless of where someone falls in that debate, SB 79 clearly represents another shift toward statewide housing policy.
Does SB 79 Eliminate Environmental Review?
No.
SB 79 is primarily a zoning and land use law, not a CEQA reform.
Projects must still comply with:
· Building Codes.
· Fire Codes.
· Environmental regulations.
· Utility requirements.
· Applicable state and local standards.
Depending on the project, other housing streamlining laws—such as AB 130, SB 131, SB 35, or the Density Bonus Law—may also come into play.
Common Misconceptions
“Every property near a bus stop can now build apartments.”
No.
Only qualifying transit facilities and qualifying projects are covered by the law.
“This applies statewide.”
No.
SB 79 is focused on designated urban transit counties with qualifying transit infrastructure.
“Cities no longer have zoning.”
False.
Cities and counties continue to regulate many aspects of development.
SB 79 modifies zoning standards in specific locations under specific circumstances.
“This means every project is automatically approved.”
No.
Applicants must still comply with all applicable development standards and permitting requirements.
The Bottom Line
SB 79 is one of California’s most significant land use reforms in recent years.
Rather than expanding housing into undeveloped areas, the law focuses on building more homes where transit infrastructure already exists.
Although the direct impact will be greatest in major metropolitan areas, the legislation reflects a broader trend that every property owner, builder, and land use professional should understand:
California is increasingly adopting statewide housing policies that limit local barriers to residential development.
Whether that trend continues remains to be seen, but SB 79 is another clear example of the State’s effort to increase housing production through targeted land use reform.
Looking Ahead
Transit-oriented development is just one piece of California’s housing strategy.
In our next article, we’ll examine SB 450, the legislation that strengthened California’s SB 9 lot split law and clarified how cities and counties must process qualifying urban lot split applications.
