ADU Potential
Wide & shallow · Corner lot · ~116 ft frontage × 119 ft deep, limited depth, an ADU likely sits beside the house rather than behind it. A second street frontage lets an ADU take its own entrance and address.
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 3,956 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.

We don't hold this jurisdiction's floor-area rule, so the default builds to roughly 3,956 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): $1,246/sqft. Sized within 25% of the 4,000 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.
