The listing's square footage against the county assessor's record and the permits on file.
The listing and the county record agree within 10%.
What can explain a difference
- Space built without a permit.
- Permitted work the assessor has not recorded yet.
- An ADU, a finished basement or a converted garage counted in one figure and not the other.
- Different measuring. Listing agents and the assessor often measure the same house differently.
Our Menlo Park permit record starts in 2017. Work permitted before then will not appear above.
AddressIntel AI Briefing
A classic teardown-and-mansionize play is the optimal strategy, supported by a massive lot, low coverage, and an aging structure in ultra-prime Menlo Park. The lack of any hazard blockers and highly favorable zoning levers also make a high-density SB 9 lot split extremely viable. Given the affluent, owner-occupied neighborhood demographics, building a premier luxury estate will capture the area's highest price-per-square-foot comps.

Screening heuristic based on lot size, existing coverage, lot orientation, and hazard overlays. CA ADU law is ministerial statewide; verify max size, setbacks, and JADU owner-occupancy with the local planning dept.
Redevelopment Potential
Meaningful unused floor-area headroom under current zoning, room to add square footage. Zoning allows roughly 3,618 sqft of gross floor area on this lot.

Proforma ROI Calculator
Back-of-the-napkin deal analysis across development strategies.
Zoning allows roughly 3,618 sqft on this lot, and the default builds to that envelope. The FAR figure is a discretionary-review trigger, not a hard cap.
Median of 12 recent single-family sales in Menlo Park (94025): $1,978/sqft, plus 5% because new houses sold at a median 1.07x their comps across 239 real rebuilds. Sized within 25% of the 3,600 sqft build, because smaller houses sell for more per foot and pricing a rebuild off them overstates resale.
Commission, transfer tax and closing. Deducted from resale before profit, so the ROI below is net of the exit rather than gross.
Interest on the purchase price for the whole project plus half the build budget, since construction draws ramp up. The default is 7% over 33 months, the median purchase-to-sale time of 239 real Peninsula and South Bay rebuilds. Set the rate to 0 for a cash purchase, or use your own lender's terms.
