Step 1
Search by address or parcel ID where available. Use the map when a source does not publish searchable addresses.
Find parcelsStep 2
Compare available zoning, flood areas, and environmental records. Keep coverage and source limitations in view.
Explore the mapStep 3
Save parcels and searches across devices. Choose alerts for new matches, with no notifications when nothing changes.
Open saved researchScreen upcoming county tax sales in minutes, then check any parcel’s environmental risk on the map.
Auto-assembled ASTM radius reports, KCSL integration, and historical aerials on one map.
Compare available mapped constraints and estimate remaining area for further investigation. Verify local requirements before making development decisions.
Compare normalized zoning across covered states, counties, and municipalities, alongside available parcel records and nationwide regulatory overlays.
Use source-published records and screening tools together. Verify material findings with the issuing agency and qualified professionals.
Toggle 30+ regulatory overlays — flood zones, wetlands, environmental sites, stream buffers — on one map. Compare mapped constraints and check each source's coverage.
Screen available EPA and state environmental records with a 0–100 parcel score where scoring is available. A low score is not a finding that a property is free of contamination.
County tax sale listings aggregated into one calendar. Free to browse. Filter by state, county, and date.
Parcels across 16 states and Washington, DC, and growing — address, property class, assessed value, acreage and more, as far as each state’s own feed publishes them.
Assemble available environmental records using ASTM E1527-21 search distances. Screening supports your research; it is not a completed Phase I assessment.
Estimate the area remaining after mapped wetlands, stream buffers, flood hazard areas, conservation easements, and preserved open space. Coverage gaps and local rules still need review; this is not a legal buildability determination.
