The optimal play is stealth density: primary + ADU + JADU to preserve the existing renovated structure, as a complete rebuild is financially unviable. Ground-up redevelopment is heavily penalized by the high entry price and liquefaction hazards. High neighborhood median income support strong end values, but a teardown-and-mansionize strategy fails to pencil.

Parcel & Zoning Info
ADU Potential
Flag / irregular · ~110 ft frontage × 115 ft deep, a tucked-away rear unit is very private; access is typically via the pole driveway.
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
Existing home already uses most of the allowable floor area, little expansion headroom. Zoning allows roughly 2,200 sqft of gross floor area on this lot.
Screening estimate comparing existing living area to the city's single-family floor-area limit. City sets no explicit FAR (or is not individually curated); allowable area is a conservative estimate. Source: conservative default (0.40 FAR — city not individually curated) (as of 2026-06-30). Verify FAR, coverage, setbacks, and height with the local planning dept.

Back-of-the-napkin deal analysis across development strategies.
We don't hold this jurisdiction's floor-area rule, so the default builds to roughly 2,200 sqft from a conservative 0.40 FAR approximation, a starting point and not a zoning answer. Check the local code before you rely on it.
Median of 12 recent single-family sales in San Carlos (94070): $1,423/sqft. Sized within 25% of the 2,200 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.
Carry on total capital for the project duration. At 0% the model is a cash purchase; 12 months at a typical construction-loan rate moves ROI by 6 to 10 points on a deal this size, so price it with your real rate.
