The weekly brief
One email a week on what actually moved: the demolition permits pulled, the lots that sold at land value, and the city-by-city numbers behind them. Free.
Permits joined to parcels
Every permit from the Peninsula and South Bay cities we track, keyed to the parcel and joined to its listing and sale history, so a permit number becomes a story about a property.
Screener, alerts and API
Screen any Peninsula address for teardown potential, watch a city or a street for new filings, or pull the whole dataset into your own tools through the API.
Backed by a real data engine
This is the engine behind the brief: every permit and demolition filing from the Peninsula and South Bay cities we ingest, joined to listings and recorded sales, then scored for teardown potential. Explore it live, or search Peninsula and South Bay building permits directly.
