AddressIntel AI Briefing
The optimal play is stealth density: primary + ADU + JADU, though the active flood zone and liquefaction soils serve as serious blockers for any additional ground-up development. An active permit shows a massive $1.3 million investment in a new single-family dwelling and ADU already underway. Due to the brand-new 2026 construction status, this asset is a high-end luxury hold with no near-term teardown viability.

Parcel & Zoning Info
ADU Potential
Flag / irregular · ~111 ft frontage × 126 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 3,020 sqft of gross floor area on this lot.
Screening estimate comparing existing living area to the city's single-family floor-area limit. FAR figure is a discretionary-review trigger, not a hard cap. Treat as approximate. Source: Burlingame Muni Code 25.10.060, Table 25.10-4 (R-1 Floor Area Ratio) (as of 2026-09-03). Verify FAR, coverage, setbacks, and height with the local planning dept.

Back-of-the-napkin deal analysis across development strategies.
Zoning allows roughly 3,020 sqft on this lot, and the default builds to that envelope. The FAR figure is a discretionary-review trigger, not a hard cap.
Median of 12 recent single-family sales in Burlingame (94010): $1,577/sqft. Sized within 25% of the 3,000 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.
Projected Profit
