San Mateo Eichlers / How many Eichlers?
A working paper
650 or 700+?
This is the most-quoted number in the neighbourhood and nobody actually knows it. Two authorities that are both usually right disagree by fifteen per cent. We are not going to pick one to sound confident — we are going to show you the disagreement, explain what makes it worse, and tell you exactly how it could be settled for good.
| Figure | Who says it |
|---|---|
| ~650 | Eichler Network — "the largest Eichler neighbourhood anywhere" |
| ~650 | eichlerforsale.com and atriare.com — same lineage, count as one |
| 700+ | SAH Archipedia — "over 700 single-family houses" |
| 700+ | Wikipedia — likely downstream of SAH |
| ~700 | fogmodern — "the largest contiguous collection" |
| 800 | Highlands Recreation District — homes served, not Eichlers |
Why it is hard
Three separate problems, stacked.
1. Two credible authorities disagree
Eichler Network is the institutional archive of the subject — it holds the deepest Eichler documentation in existence and its director restored the X-100. SAH Archipedia is peer-reviewed architectural history published by the Society of Architectural Historians. Neither is a source you dismiss. They are roughly fifty to a hundred houses apart.
2. The 800 keeps contaminating it
The Recreation District describes itself as serving about 800 homes, and that number circulates as if it were an Eichler count. It is not. The neighbourhood contains traditional houses built by Whitecliff, later infill including the eleven eventually approved for the Chamberlain Development Group, and individual newer builds. Anyone counting parcels rather than Eichlers will overcount.
3. The boundary you count matters
The Eichler tract and the Highlands census place are different shapes, and the census place is larger. Count inside the CDP and you will pick up houses Eichler never touched. Both boundaries, side by side →
And one more, on the outside
Published totals for San Mateo overall are 900 and about 850. Both are the contested Highlands figure plus a 19th Avenue Park figure that is itself given as 200, 235 or 240 depending on the page — one source uses both 235 and "over 200" on different pages of its own site. The honest range for San Mateo is roughly 850 to 950.
The claim that the Highlands is Eichler's largest single contiguous tract holds up. No other single tract is close: the largest in San Jose is Fairglen at around 250. Palo Alto has around 2,700 Eichlers originally, but spread across 32 separate tracts, none approaching 650.
What does not hold is "the most Eichlers of any city" — that is Palo Alto — or "largest collection in the world," which is rhetorically empty given Eichler built only in California. Say "the largest single Eichler tract ever built." That one is defensible.
Search recorded subdivision maps by volume and page for the Highlands subdivisions through the San Mateo County ACRE property-maps portal, or in person at the County Recorder, 555 County Center, 1st Floor, Redwood City, (650) 363-4500. Pull the unit and increment numbers and the lot count on each recorded map, then sum the Eichler-era units.
That would resolve the count and the missing construction increments at the same time — and it would be original research no other Eichler site has done. It is on our list. When we do it, the result will go here with the map references attached, whichever way it comes out.
Sources differ. Eichler Network puts the Highlands at approximately 650 Eichlers; SAH Archipedia and Wikipedia say over 700. We have not been able to reconcile the two.

Have you got a recorded map, or a tract number?
We are trying to count this properly. Original paperwork, a subdivision map reference, a title report with the tract name on it — any of it helps, and we will publish the result with credit.
