Ask a Los Altos resident what Measure D is about and most will say parking. Ask a land-use attorney and the answer changes. The November 3, 2026 ballot measure concerns ten surface lots behind Main Street, with potential housing and zoning implications for buyers looking at nearby homes.
Here is the short version. Los Altos has to prove to the state that it has room for a set number of new homes. Right now, a chunk of that proof lives in the same asphalt everyone parks on when they run into Draeger's or grab coffee downtown.
What's Actually on the Ballot
Measure D began as a citizen petition. A group called ForLosAltos, backed by residents and roughly sixteen downtown business owners including Draeger's Market owner Richard Draeger, collected more than 2,600 valid signatures in the spring, well past the threshold needed to qualify. According to the City of Los Altos, the measure would require voter approval before the City Council can sell, repurpose, or substantially alter any of ten city-owned downtown parking plazas, with two lots, known as Plazas 7 and 8, carved out because they're already earmarked for affordable housing.
The City Council did not just wave it onto the ballot. Under Elections Code Section 9212, the city commissioned an independent risk analysis before deciding what to do with it. That report, delivered in June, flagged concerns about litigation exposure and housing compliance. On June 23, 2026, the council voted 4-0 to send the measure to voters without alteration rather than adopt it outright. Vote-by-mail packets go out October 5. Election Day is November 3.
None of that is the interesting part. The interesting part is what happens to the math if it passes.
Why Surface Parking Counts as Housing Inventory
A Housing Element is essentially a state-approved plan showing where a required number of new homes could realistically get built. Los Altos's 2023-2031 plan counts roughly 124 units across those ten downtown lots, about eight acres in total.
Take those lots out of play and the arithmetic still has to balance. A Palo Alto Daily Post report quoted state housing official Brian Heaton saying that if voters approve Measure D, the council will need to find new places for that housing, or risk fines and a loss of local control. Vice Mayor Larry Lang has said publicly that the likely fallback is not more downtown density but rezoning inside existing commercial parcels, pointing to sites like the Lucky supermarket at 2175 Grant Road or Andronico's at 690 Fremont Ave as places the city might have to consider instead.
Opponents of the measure go further, arguing that if the downtown sites disappear from the inventory and the Housing Element gets flagged as noncompliant, the exposure does not stop at commercial corridors. It reaches R1-zoned residential streets, the ones that make up most of the city's land area. Supporters of the measure dispute how likely that outcome really is. A Los Altos Online report quoted Jon Baer, president of Friends of Los Altos, telling the council in June that the risk report was heavy on hypotheticals: "There are lots of 'coulds,' not 'woulds.'" Both sides agree on the trigger. They disagree about how far the effects could extend.
The Building That Already Happened
Here is where the argument stops being theoretical. In 2023, a developer filed plans for a four-story, twelve-unit project at 349 First Street, at the corner of First and Whitney, two blocks from Main Street. SFYIMBY reported that the application invoked Builder's Remedy.
The plans grew. By the time the project came back to council on August 25, 2026, it had become a six-story, 84-foot, 19-unit condominium tower, with four units set aside as deed-restricted affordable housing, according to the CEQAnet project record. A Los Altos Online report said the council had no legal path to stop it or shrink it. Members approved the resolution.
That building is an example of what a compliance gap can produce in Los Altos: a real structure rising at First and Whitney. The Measure D debate also concerns how the city might meet housing requirements if downtown lots become unavailable.
What Passing or Failing Actually Changes
| If Measure D Passes | If Measure D Fails | |
|---|---|---|
| Downtown parking plazas | Locked in current form except Plazas 7 and 8, absent a future public vote | Council retains authority to redevelop lots under existing housing element plan |
| Housing Element status | Litigation risk and possible state review, per city's 9212 report and HCD's letter | City proceeds with existing 124-unit downtown allocation as filed |
| If compliance lapses | Critics say replacement housing could be needed in commercial corridors or R1 zones | Downtown redevelopment remains the primary pressure valve, as intended in the current plan |
| Litigation exposure | Pro-housing group YIMBY Law has said it is prepared to challenge the measure | City avoids that specific challenge, though other housing litigation risk persists regardless |
The city has direct experience with what unresolved housing litigation costs. Opponents of Measure D point out that Los Altos has already spent more than $4.2 million on the 40 Main and 5G lawsuits. That figure describes past spending on those cases; whether Measure D itself would produce comparable costs is uncertain.
What This Means If You're Looking Near Downtown or the Corridors
If you're touring homes in Los Altos right now, the question worth asking isn't whether Measure D will pass. Nobody can answer that with confidence three weeks before ballots go out, let alone about seven weeks before Election Day. The more useful question is where a given property sits relative to the pressure points this measure either locks down or leaves open.
A home on a quiet R1 street a mile from downtown looks stable today, and the current Housing Element plan is built specifically to keep density concentrated downtown and along El Camino Real and San Antonio Road rather than in residential neighborhoods. That is the plan as filed. What 349 First Street demonstrates is that plans can change once a compliance gap opens.
For buyers evaluating corridor-adjacent commercial parcels, or lots near the Lucky supermarket and Andronico's sites Vice Mayor Lang named as potential alternates, those sites remain part of the discussion about possible housing locations.
None of this is a reason to avoid Los Altos. It is a reason to ask sharper questions before you write an offer, particularly if long-term zoning stability matters to your decision the way it does for many families choosing a neighborhood for the next decade rather than the next listing cycle.
