The $380K Lot That Couldn't Be Built — A Cautionary Tale
Data version: Q2 2026 · Last updated 2026-05-13
TL;DR. A Bay Area buyer paid $380K for a lot that turned out to be unbuildable due to a hidden overlay restriction. How Buildability™ would have caught it in 20 seconds.
Summary
An investor paid $380,000 for a California lot believing it was a straightforward infill opportunity. The problem: an overlay district flagged the parcel for seismic fault setback that eliminated 85% of the buildable area. The investor discovered this 6 months after closing, during architect review. Total loss after sale: $160K. Lesson: modern property risk is in the overlays, not the base zoning. Overlay districts are exactly what the Buildability Score™ screens for.
