AddressIntel AI Briefing

This property offers strong potential for a stealth density: primary + ADU + JADU play given the mid-sized lot and older home structure. However, liquefaction serves as a notable geotechnical development blocker that will increase foundation and engineering costs. While SB 9 remains structurally possible, developers should focus on structural expansion over an outright lot split to mitigate seismic mitigation overhead.

ADU Potential

Feasibility Score94/100
Max ADU Units2 (ADU + JADU)
Est. ADU Size1,200 sqft
Existing Coverage20.5%

Flag / irregular · Corner lot · ~139 ft frontage × 153 ft deep, a tucked-away rear unit is very private; access is typically via the pole driveway. 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.

Seller Motivation

Motivation Score6/100
Low motivation
30+ days on market

Inferred from days on market and listing-description language (e.g. "as-is", "estate sale", "motivated seller"). A screening heuristic for likely negotiability, not a statement about the seller's circumstances.

Redevelopment Potential

FAR Utilization51% of allowed
Buildable Headroom+2,030 sqft

Meaningful unused floor-area headroom under current zoning, room to add square footage. Zoning allows roughly 4,160 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.

Proforma ROI Calculator

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 4,160 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): $1,125/sqft, plus 5% because new houses sold at a median 1.07x their comps across 239 real rebuilds. Sized within 25% of the 4,200 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.

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.
