What this place is
Most of it is zoned Open Space with a ten-acre minimum lot — and building a single house needs a City Council vote.
The hills are not simply a large-lot version of the rest of Palo Alto. They are a different regulatory world. Foothills parcels sit in the Open Space district: ten-acre minimum parcel size, a twenty-five-foot height limit, impervious coverage capped at under five percent of the site, and a single-family house requires Site and Design Review approved by the City Council after the Planning Commission has seen it. Houses are expected to sit away from hilltops and below the nearest ridgeline.
Smaller parcels can still be buildable if they are legal parcels predating incorporation — a distinction that decides whether a piece of land is worth anything at all, and one that no portal will ever tell you.
The city was sued over that zoning and lost. In the Arastra case, 515 acres at Page Mill and Arastradero were rezoned to Open Space in 1972 after the council had already resolved to acquire them; a federal court found inverse condemnation, holding the regulations were designed not to control development but to prevent it. The land is now the Enid Pearson-Arastradero Preserve.
The specifics
- Open Space zoning: ten-acre minimum parcel, twenty-five-foot height limit, impervious coverage capped at roughly 4.7 percent of site area, and City Council approval of a Site and Design Review for a single house.City of Palo Alto — Site and Design Review staff report
- A parcel under ten acres can still be buildable if it is a legal parcel predating incorporation. One Los Trancos Road parcel qualifies because it has been a legal parcel since the 1850s.City of Palo Alto — staff report
- In Arastra Limited Partnership v. City of Palo Alto, 515 acres at Page Mill and Arastradero were rezoned to Open Space in August 1972. A federal court found inverse condemnation, holding the regulations “were designed not to control development… but rather to prevent it".Justia — 401 F. Supp. 962
- The city bought 433 acres in 1976 for what is now the Enid Pearson-Arastradero Preserve, since grown to 622 acres.
- Foothills Nature Preserve was bought from Dr Russel V. Lee — 1,194 acres at $1,000 an acre in 1958 — and opened in June 1965. Santa Clara County offered $500,000 toward it in 1964 on condition it be open to everyone; Palo Alto declined. It was residents-only until a council vote in November 2020 opened it to all.City of Palo Alto — open space brochure
- Palo Alto Hills Golf & Country Club was incorporated in August 1958 on 145 leased acres; the first nine holes opened in May 1960. It converted the lease to a purchase in 1962 and says it was the first Bay Area club to own its own land.Palo Alto Hills Golf & Country Club
- Two places have confusingly similar names and are not the same. Los Trancos Road off Page Mill is in Palo Alto, Santa Clara County. Los Trancos Woods is unincorporated San Mateo County with Portola Valley addresses, subdivided in 1959.
Palo Alto Hills in one paragraph
16 homes sold in Palo Alto Hills over the last year, at a median of $4.41M — above the Palo Alto median of $4.01M. The typical one is a 3,282 sq ft two-story house from 1972 on a 40,800 sq ft lot, at $1,583 a square foot.
Against the price sellers first asked — not the price they had been reduced to — the median sale here finished −5.0%, and 38% of sellers got at least their asking price. That is weaker than Palo Alto as a whole, where the median is +5.5%. Here the first number has to be closer to right, because the market is less inclined to correct it upward.
In Palo Alto Hills, the first two weeks are the sale
Every sale grouped by how long it took, against the price it first asked. Not against a reduced price — against the number it launched at.
Homes here that sold in the first week finished +4.6% against their opening price. The ones still on the market after sixty days finished −16.0%. That gap is not explained by price — the slow sellers are not the cheap ones. Whatever is going to happen, happens early.
Every sale: what it fetched, and how it did
One dot per home. Across is the result against the price it first asked. Up is what it actually sold for. Red beat its asking price; charcoal did not.
The dashed lines are the two medians — $4.60M and −5.0%. A dot to the right of the upright line beat the price it opened at; a dot above the flat one sold for more than the typical home here. What the corners tell you is whether the top of Palo Alto Hills behaves like the rest of it.
If this is your street
The map says what sold. It doesn’t say what yours would.
Two houses on the same Palo Alto Hills block can be hundreds of dollars a square foot apart, and the difference is almost never the house — it is what was done to it before anyone saw it. Maggie will tell you which of those things is worth doing on yours, and which is not.
