Coverage

Locus distinguishes national lanes (work for any US point or county) from place-specific lanes (verified source cards for particular jurisdictions). Coverage gaps are stated honestly, never hidden.

National lanes (any US address)

These resolve for any US address (NC addresses geocode via the state geocoder; elsewhere via OpenStreetMap/Nominatim):

Flood zone — FEMA National Flood Hazard Layer
Property tax — NCDOR statewide table (NC); plus an estimated annual tax when the county publishes assessed value
Environmental — EPA toxic-release (TRI), hazardous-waste handlers (RCRA), drinking-water systems (SDWIS), with spill/dump history links
Governing districts — Census TIGERweb
Storm events — NOAA Storm Events
What’s nearby — OpenStreetMap (food, schools, parks, transit, healthcare, civic, and more)
Housing stock — Census ACS

Place-specific lanes (verified source cards)

Permits, development cases, capital projects, parcel transfers, and local transit are verified for specific jurisdictions and reported honestly as not-yet-covered elsewhere. Current verified and candidate markets include Raleigh / Wake, Chatham (where stable open endpoints exist), Chicago, and Charlotte / Mecklenburg (311 and code enforcement verified; CMPD crime is opt-in only via includeCrime=true).

Verified vs candidate sources

Each source is a card with a status:

Verified — the source has been confirmed and is used in coverage and paid briefs.
Candidate — discovered but not yet verified; surfaced for transparency, not used to charge.

Check any place with the free locus_coverage_check and locus_source_card_check tools — they return the jurisdiction stack, verified sources, and missing recommended sources before any paid call.
