AddressIntel AI Briefing
With an exceptionally low lot coverage of 17% and a massive 13,424 sqft lot, the optimal play here is an SB 9 lot split into 4 units to maximize the high-income San Carlos demographic. Alternatively, a teardown-and-mansionize strategy works perfectly given high-value local addition permit activity and zero hazard blockers.

ADU Potential
Flag / irregular · ~191 ft frontage × 201 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
Small, older home using a low share of the allowable building envelope on a sizable lot, a scrape-and-rebuild or major-expansion play. Zoning allows roughly 5,370 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 5,370 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 5 recent single-family sales in San Carlos (94070): $1,108/sqft. Sized within 25% of the 5,400 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.
