AddressIntel AI Briefing

Although the 1946 house is small, a flood AE zone and liquefaction act as severe development blockers, completely stopping SB 9. Additionally, the home is already fully updated and move-in ready. The most logical approach is a long-term buy-and-hold to capitalize on the high San Carlos demand.

ADU Potential

Feasibility Score72/100
Max ADU Units2 (ADU + JADU)
Est. ADU Size1,200 sqft
Existing Coverage19.1%

Flag / irregular · Corner lot · ~104 ft frontage × 107 ft deepa 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.

Redevelopment Potential

Redevelopment Score56/100
ClassTeardown candidate
FAR Utilization48% of allowed
Buildable Headroom+1,038 sqft

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 1,988 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.
