What SB 79 allows near rail and bus rapid transit, why the City of Los Angeles deferred it until about 2030, and what that means for apartment owners.
What Is SB 79?
Senate Bill 79 (Senator Wiener; Chapter 512, Statutes of 2025) was signed on October 10, 2025 and began applying to cities on July 1, 2026. It makes multifamily housing an allowed use near rail and bus rapid transit stops in California's most transit-rich counties, including Los Angeles County, and sets minimum height, density and floor-area standards that cities must accept on qualifying sites.
For owners in the City of Los Angeles, the more important fact is local: the City Council deferred SB 79's standards citywide until roughly 2030. This article explains what the state law does, what Los Angeles did instead, and what that means if you own an apartment building near transit.
Where SB 79 Applies
SB 79 applies only in "urban transit counties," meaning counties with more than 15 passenger rail stations. Within those counties it applies to sites zoned residential, mixed-use or commercial that are within a half mile of a qualifying stop. In cities with fewer than 35,000 residents, only sites within a quarter mile qualify. Unincorporated county areas are not covered until the next regional housing needs cycle.
Which Transit Stops Count
The law sorts stops into two tiers, and ordinary bus stops are not in either one:
- Tier 1: Stops served by heavy rail (in Los Angeles, the B and D subway lines) or by commuter rail with at least 72 trains a day
- Tier 2: Stops served by light rail, by commuter rail with at least 48 trains a day, or by bus rapid transit with dedicated lanes
Regular local buses and "Rapid" bus lines do not qualify, however frequent the service.
What the State Standards Allow
On a qualifying site, a city must allow a housing project of at least five units up to these limits:
| Location | Height | Density | Floor area ratio |
|---|---|---|---|
| Tier 1, within a quarter mile | 75 feet | 120 units per acre | 3.5 |
| Tier 1, a quarter to a half mile | 65 feet | 100 units per acre | 3.0 |
| Tier 2, within a quarter mile | 65 feet | 100 units per acre | 3.0 |
| Tier 2, a quarter to a half mile | 55 feet | 80 units per acre | 2.5 |
Sites within 200 feet of a stop get an additional 20 feet of height, 40 units per acre and 1.0 of floor area ratio.
Affordability
Projects with more than 10 units must set aside 7% of units for extremely low income households, 10% for very low income households, or 13% for lower income households, or meet a stricter local requirement. Projects of 10 units or fewer are exempt from this set-aside.
Approval Process
SB 79 does not by itself make a project ministerial. Streamlined ministerial approval is available only if the project also meets the requirements of SB 423, including that law's affordability and labor rules. Buildings over 85 feet must meet additional labor standards.
Sites That Do Not Qualify
SB 79 has anti-displacement limits that matter to owners of existing apartment buildings:
- A site with more than two units is ineligible if the project would demolish rent-controlled housing that tenants occupied in the past seven years
- A site is also ineligible if such units were demolished in the previous seven years
- The state's replacement-housing rules for demolished units continue to apply to other housing
In practice, an occupied rent-stabilized building of three or more units is not an SB 79 redevelopment site.
What Los Angeles Did Instead
SB 79 lets a city temporarily exclude certain areas and adopt its own alternative plan. The Los Angeles City Council used that option. On June 23, 2026 it adopted two ordinances, both effective June 30, 2026:
- Phased Implementation Ordinance (Ordinance 188968): Defers SB 79's state standards citywide until one year after the city's next housing element, which is roughly 2030
- Low-Rise Ordinance (Ordinance 188967): Allows buildings of up to four stories in 57 station areas in the meantime
The state housing department sent the city a technical assistance letter about its approach on June 22, 2026. Whether the state accepts the city's ordinances as adopted is something to keep checking, because it determines when the full state standards could apply in Los Angeles.
Other cities in Los Angeles County have made their own choices. A property in Santa Monica, Culver City or Burbank is governed by that city's response, not by the City of Los Angeles ordinances.
How to Check a Specific Property
- City of Los Angeles: Look up the parcel in ZIMAS, where the city posts local eligibility
- Region-wide: Use the official tiered map published by the Southern California Association of Governments
- Fire zones: Cities may temporarily exclude sites in very high fire hazard severity zones, and may shift density away from them in a state-approved alternative plan
What This Means for Apartment Owners
If You Own an Existing Building in the City of Los Angeles
- SB 79's state height and density standards are not in force on your parcel today
- If your building is rent-stabilized with three or more units, SB 79 would not make it a redevelopment site even when the standards do apply
- The four-story Low-Rise Ordinance may be relevant if you are near one of the 57 station areas
- Adding accessory dwelling units is often a more realistic way to add units than demolition; see ADU rules for LA apartment buildings
If You Are Selling
Be careful with claims that transit proximity has raised your land value because of SB 79. In the City of Los Angeles the state standards are deferred, and buyers who underwrite development potential will check ZIMAS before they pay for it. Price the building on its income and comparable sales, and treat development potential as upside only where the zoning supports it today.
If You Are Buying
Confirm what is actually buildable under current local rules before paying a premium for a site near a station. The answer differs by city within the county.
How SB 79 Fits With Other Laws
- SB 1211: Up to eight detached ADUs on multifamily properties
- SB 423: Streamlined approval for projects that meet its standards
- Density bonus law: Additional incentives for affordable units
- AB 507: Conversion of commercial buildings to housing
Quick FAQs
Q: Does SB 79 eliminate local zoning?
A: No. It sets minimum standards near qualifying rail and bus rapid transit stops, and it lets cities adopt state-approved alternative plans.
Q: Can I tear down my rent-stabilized building and rebuild under SB 79?
A: Generally no. Sites with more than two rent-controlled units occupied in the past seven years are ineligible.
Q: Is SB 79 in effect in Los Angeles?
A: It took effect statewide on July 1, 2026, but the City of Los Angeles deferred the state standards until about 2030 and adopted a four-story Low-Rise Ordinance for certain station areas.
Q: Does my bus stop count?
A: Only bus rapid transit with dedicated lanes counts. Regular and Rapid bus stops do not.
