California's transit housing law, SB 79, took effect July 1, 2026. Eight days later, a developer filed an application that depends on the Menlo Park Caltrain station. The lot was in Atherton, and the plan was to replace one house on Glenwood Avenue with 30 townhomes. According to the research behind this post, no application had been filed under SB 79 for any parcel inside Menlo Park as of October 2026.
A law described as allowing 75-foot buildings near Caltrain got its first local use from the town next door, at 45 feet. A population cutoff halves the radius of Menlo Park's coverage, and zoning the city already had covers most of what the law would add downtown. Anyone comparing Mid-Peninsula cities, or owning near downtown Menlo Park, will find the station-area picture makes more sense once both are clear.
The one-acre lot at Glenwood and Laurel
The Almanac reported that on July 9, AlphaX RE Capital Inc. filed an application under SB 79 to replace a single-family home on a 1-acre lot at 110 Glenwood Ave. with 30 townhome units, six of them affordable. The buildings would be three stories and up to 45 feet tall. The site is at the corner of Glenwood and Laurel Street, near Nativity School.
Atherton's own Caltrain station has been closed for years and does not qualify under the law. The Almanac explained that seven Atherton parcels sit within a quarter mile of the Menlo Park station's pedestrian access, and that is how the application qualifies. The town confirms the seven-lot count on its SB 79 FAQ page. Town officials said the application was in early review as of the July 31 report.
The arithmetic shows how modest the proposal is. Thirty units on one acre works out to 30 units per acre, which is the minimum density a project needs to qualify under SB 79. The quarter-mile ring allows up to 120 units per acre and 75 feet. So the first filing tied to Menlo Park's station sits at the law's floor. It is nowhere near the ceiling.
A quarter mile, set by a population count
SB 79 sorts transit stops into tiers. Menlo Park's Caltrain station is a Tier 1 stop, the category for heavy rail and very frequent commuter rail. Around Tier 1 stations, the law sets three rings of minimum standards. Inside each ring, local rules cannot cap height, density or floor area below these figures:
| Distance from station access | Height | Density | Floor area ratio | Applies in Menlo Park today? |
|---|---|---|---|---|
| Within 200 feet | 95 feet | 160 units/acre | 4.5 | Yes |
| Within 0.25 mile | 75 feet | 120 units/acre | 3.5 | Yes |
| 0.25 to 0.5 mile | 65 feet | 100 units/acre | 3.0 | No |
The outer band applies only "within a city with a population of at least 35,000," according to the chaptered bill text. Menlo Park's May 12, 2026 staff report cites California Department of Finance estimates of 33,326 residents in 2025 and 33,785 in 2026, and concludes:
"Because of Menlo Park's population, SB 79 development standards are applicable to sites within 0.25 miles of a qualifying transit stop."
The same report points out a second effect of the threshold. No Menlo Park parcels are within a quarter mile of the Palo Alto Caltrain station, but some are within half a mile of it. The report says that if Menlo Park's population passes 35,000, those parcels would come under the half-mile standards too.
Today the city is 1,215 residents short of the line, using the 2026 estimate. Between the 2025 and 2026 estimates it added 459. One caveat: the statute does not say which population source or measurement date controls, and it does not say whether coverage changes automatically when a city crosses 35,000. The city's statement about the Palo Alto parcels is its own reading of the law. The bill text does not spell it out.
Why downtown has not needed the law
The second half of the explanation is zoning Menlo Park already had. Staff identified 130 parcels on 43.3 acres in five subdistricts of the El Camino Real/Downtown Specific Plan that already allowed at least half of SB 79's density and floor area. Staff then proposed a temporary ordinance excluding those parcels from SB 79 until no later than Jan. 31, 2032.
The capacity comparison in that report explains why downtown developers have had little reason to use the state law:
| Subdistrict | Parcels | Existing bonus-level capacity as share of SB 79 |
|---|---|---|
| D, Downtown | 54 | 83% |
| SA-W, Station Area West | 17 | 83% |
| SA-E, Station Area East | 45 | 66% |
| ECR-SE, El Camino Real South-East | 3 | 67% |
| ECR-NE-R, El Camino Real North-East Residential Emphasis | 8 | 58% |
| Total, as printed | 130 | 66% |
The parcel counts above are copied from the staff report's table. Its subdistrict rows sum to 127, while its total row and the report's text both give 130.
Affordability rules point the same way. SB 79 says that when a local inclusionary ordinance requires more affordable units, or deeper affordability, the local rule applies. Staff concluded that Menlo Park's requirements are higher, so the city's own affordable housing minimums apply to every SB 79 project. A developer downtown gets somewhat more capacity under SB 79 than under the Specific Plan's bonus levels, but not a different set of affordability obligations.
The Planning Commission voted 5–1 at its April 27 meeting to recommend no exemption. On May 12 the City Council took no action on the ordinance and directed staff to keep it informed of applications filed under SB 79. As a result, the law's default standards took effect July 1, 2026.
The tallest active downtown proposal shows the same pattern. At 800 Oak Grove Ave., also addressed 1221 Crane St., the applicant asked for 15 condominiums in a six-story building of roughly 72 feet, along with conversion of the existing bank building to office use. The project relies on State Density Bonus Law, not SB 79. It includes one very-low-income unit plus an in-lieu fee for the rest of its below-market-rate obligation. The Planning Commission approved it 7–0 on Sept. 14, and the tentative map went to the City Council on Sept. 22. The research did not confirm the council's final vote. The applications were first submitted Dec. 23, 2025, before SB 79 took effect, and went through several rounds of revision during 2026.
Where the quarter mile touches single-family zoning
The proposed exemption would have covered only the five Specific Plan subdistricts. The staff report lists other zoning districts inside the quarter-mile ring where SB 79 applies, including R-1-S Single Family Suburban Residential, R-1-U Single Family Urban Residential, and R-E Residential Estate. Those zones never got the Specific Plan's added capacity, so SB 79 is a bigger change for them than for downtown. The Glenwood filing is an example of that kind of parcel, though it sits on the Atherton side of the line.
Inclusion in an eligible zone is only the starting point. Under SB 79, a qualifying project must:
- Include at least five residential units
- Reach at least 30 units per acre, or the local minimum if higher
- Keep average unit size to 1,750 net habitable square feet
- Exclude hotel uses
- Meet affordability requirements, which in Menlo Park means the city's own standards
Distance is measured from a parcel's nearest edge to a station pedestrian access point. The text of SB 79 also makes clear that being in a qualifying zone does not mean every individual lot can fit a compliant project. The 200-foot ring creates its own exceptions. Staff found three ECR-NE-R sites within 200 feet of the station whose zoning falls short of the minimum density test: 1300 El Camino Real, a parking parcel between Garwood Way and the Caltrain corridor at Oak Grove Avenue, and 530 Oak Grove Ave.
The rules still moving
Several pieces were unsettled as of mid-October 2026:
- AB 2576 was chaptered in September 2026. It lets local ordinances exclude certain historic resources listed before 2025 from SB 79. The research did not establish whether any Menlo Park sites qualify.
- AB 2415 proposes a historic-district reduction for some smaller cities. Its last recorded action, on Aug. 19, 2026, showed Assembly concurrence pending.
- Regional filings have been sparse. California YIMBY's Aug. 3 roundup listed proposals in Palo Alto, San Mateo, Atherton, South Pasadena and Santa Monica after the first month and said the list might be incomplete.
Frequently asked questions
Does SB 79 cover every home near the Menlo Park station? It covers residential, commercial and mixed-use parcels within a quarter mile of a station pedestrian access point, measured from the nearest parcel edge. A project must still meet the law's minimums on unit count, density and unit size.
Could the covered area get larger? The city's staff report says the half-mile tier, including parcels near the Palo Alto station, would apply if Menlo Park's population passes 35,000. The statute does not specify how or when population is measured.
Was the 75-foot figure ever accurate? Yes. The Almanac's November 2025 explainer reported 75 feet within a quarter mile and 95 feet next to the station. Those are the minimum standards local rules must allow. They do not describe what a developer will propose. The first local filing came in at 45 feet.
If you own near downtown Menlo Park, it helps to know which SB 79 rules reach your parcel, and which don't, before you set a list price or write a disclosure.
