Compare Saratoga and Los Gatos on paper and the gap looks like a story about neighborhoods. Over the three months ending May 2026, Saratoga's median sale price ran about $4.1 million against roughly $2.4 million in Los Gatos, and Saratoga's price per square foot sat near $1.5K compared with about $1.31K in Los Gatos. Other aggregators pull slightly different exact figures for the same stretch, the direction and the size of the gap hold steady. Saratoga costs more, by a wide margin, on every measure a portal puts on a homepage.
What that comparison never tells you is why. The two towns sit five miles apart, share a high school district, and pull from many of the same employers. The real difference is not the roofline or the finish level. It is the ground the house sits on, and increasingly, how long City Hall takes to let you touch it. For anyone weighing whether to buy an existing home, buy new construction, or build on a lot in this county, that distinction is the one worth understanding before comparing another median.
The Permit Clock That Never Shows Up in a Comps Sheet
Start with the part that surfaces only once someone is actually trying to build. Plan check for new residential construction across Santa Clara County currently runs 8 to 16 weeks, and that range hides real variation by city. Los Gatos typically processes a residential plan check in 10 to 12 weeks. Saratoga and Los Altos fall in a similar band. Palo Alto is the outlier, averaging 14 to 20 weeks because of additional architectural review board requirements and a heavier volume of applications moving through the same office.
That gap is not a bureaucratic footnote. A project carrying financing, insurance, and a rented residence for an extra two to three months has a real dollar cost attached to it, one that never appears in a median price and rarely gets modeled until a buyer is already under contract on a lot. If you are comparing a Palo Alto teardown to a similarly priced Los Gatos one, you are not just comparing land. You are comparing how long your capital sits idle before a shovel goes in the ground.
The same pattern holds inside a single project type. Cupertino, for instance, processes ADU permits in roughly 4 to 8 weeks for initial review, with each correction cycle adding another 2 to 3 weeks, a timeline that stays workable if the submittal is complete on the first pass. A full custom home in a city with a design review layer does not get that benefit. The friction scales with how much discretionary review a project triggers, and that review load is set locally, city by city, not countywide.
What the Lot Actually Costs
Once the permit clock is running, the next number that reshapes the budget is the one buyers underweight most: the lot itself. According to one Bay Area design-build firm's 2026 project data, drawn from real contracts across Los Gatos, Saratoga, Palo Alto, and Menlo Park, the lot now represents 40 to 60 percent of total all-in project cost on a custom build in this market, a ratio the firm describes as dramatically higher than almost anywhere else in the country.
Put that in dollars and the city-to-city variation becomes obvious. In downtown Los Gatos, teardown properties on standard 7,000 to 10,000 square foot lots regularly sell for $1.8 million to $2.5 million, before a single wall comes down. In Saratoga, a lot in a top-rated school district runs $2 million to $4 million. On the Peninsula, lot values in Menlo Park's Allied Arts neighborhood or Palo Alto's Professorville can exceed $4 million on their own.
| City | Typical standard-lot price, teardown condition (2026) | New-construction permit review time (2026) |
|---|---|---|
| Los Gatos | $1.8M–$2.5M on 7,000–10,000 sq ft lots | 10–12 weeks |
| Saratoga | $2M–$4M in top-rated school districts | Similar to Los Gatos |
| Palo Alto (Professorville) | Lot values exceeding $4M | 14–20 weeks, due to architectural review |
| Menlo Park (Allied Arts) | Lot values exceeding $4M | Not separately tracked in county data |
Hard construction costs, by contrast, are far more consistent across cities. Mid-range to high-end custom builds budget $550 to $750 per square foot in 2026, and a simple, efficiently shaped floor plan on a flat lot can bring that down to $450 to $550. The building itself is close to a commodity cost. The land underneath it is not.
Reading the Median Correctly
That reframes the Saratoga-versus-Los Gatos comparison entirely. A meaningful share of Saratoga's higher median is not paying for more house. It is paying for more land, and specifically for lots that tend to run larger, roughly 10,000 to 40,000 square feet in Saratoga's single-family zoning compared with a wider mix of smaller downtown parcels and larger hillside lots in Los Gatos. Two buyers spending the same total budget in each city are not choosing between comparable homes. They are choosing between different amounts of buildable and usable land, with the structure itself scaling to fit what's left in the budget.
This matters most for anyone evaluating a teardown or a raw lot rather than a finished home, because the sale price they're comparing against a neighboring city's median was never really commodity pricing. It was land pricing wearing a house-price label. Add school impact fees, which run $4.79 to $5.85 per square foot in most Santa Clara County districts, plus the $60,000 to $120,000 in combined permitting, park, traffic, and fire district fees that a custom single-family project typically carries, and the final number on a build has very little to do with the number a portal displays as the neighborhood's median.
Where This Changes the Calculus
For a buyer evaluating a large lot, the land's ratio to total cost cuts both ways. A bigger parcel means a bigger check at close, but it also means more flexibility later. Saratoga's larger lots, many over 10,000 square feet, make detached accessory dwelling units particularly feasible on properties where a smaller lot would rule one out entirely. A permitted ADU is commonly estimated by builders and appraisers to add value roughly equal to 100 times its expected monthly rent, which means a lot's size is not just about the primary residence. It is about what else the parcel can support over time.
For a seller sitting on an older home on a desirable lot, the retain-and-remodel path is worth a conversation before defaulting to teardown. Keeping at least one structural wall in place, rather than a full rebuild, can in some cases help preserve a lower Proposition 13 assessed value basis, though that determination depends on the specifics of the property and should be worked through with both a builder and a property tax professional rather than assumed from a general rule.
And for anyone budgeting a build from the ground up, the number to plan around is not the per-square-foot hard cost. It is the full stack: lot acquisition, $100,000 to $350,000 in landscaping and hardscaping depending on scope, the fee load described above, and a carrying-cost buffer sized to whichever city's review board you happen to be waiting on.
A Few Questions Worth Asking First
Does a lower median price in one city automatically mean better value? Not on its own. It can mean smaller average lots, a different zoning minimum, or simply a different mix of what sold that quarter. The number worth asking a builder or agent for is the land-to-total-cost ratio on comparable recent projects in that specific city, not the city's median sale price.
Is it ever cheaper to buy an already-built new-construction home instead of building? Sometimes, and it depends heavily on whether you already own the lot. If you're starting from raw land or a teardown, building typically lands well below the price of purchasing a comparable finished new home in Los Gatos or Saratoga. If you don't yet own land, the acquisition cost of a desirable lot can erase that advantage quickly.
How much should I budget beyond the advertised cost per square foot? Plan for the lot, the fee load, landscaping, and a timeline buffer sized to your city's permit review pattern, not just the hard construction number. In this county, the gap between a rough budget and a real one is almost always the land and the calendar, not the framing lumber.
