Difference
-531 (-22%)

The listing reports 531 sqft less than the county has on record.

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.

AddressIntel AI Briefing

The optimal play is an SB 9 lot split into multiple units, taking advantage of the large 7,841 sqft lot and perfect ADU feasibility rating. Since the existing home is already remodeled and turnkey, developers can retain the front structure for immediate income while building out new units on the rear split lot with zero site blockers.

Proforma ROI Calculator

Back-of-the-napkin deal analysis across development strategies.

Zoning allows roughly 3,528 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 Campbell (95008): $994/sqft, plus 5% because new houses sold at a median 1.07x their comps across 239 real rebuilds. Sized within 25% of the 3,500 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.
