AddressIntel AI Briefing

The optimal play is stealth density: primary + ADU + JADU, but any expansion is heavily constrained by the existing 48% lot coverage. Because the current home matches the maximum 40% FAR limit, a teardown or major addition is financially blocked by zoning.

Existing home already uses most of the allowable floor area, little expansion headroom. Zoning allows roughly 2,400 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.

Zoning allows roughly 2,400 sqft here, less than the 2,900 sqft standing today, so a compliant rebuild would be smaller than the existing house. We don't quote a return on this one. Demolishing generally forfeits the existing non-conforming floor area, so treat it as a remodel or check the local code for what it lets you rebuild.

Median of 12 recent single-family sales in Belmont (94002): $1,092/sqft. Sized within 25% of the 2,900 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.
