- Accept any disclaimer, then look for a search box that takes street addresses, owners or parcel IDs.
- Zoom in and click a parcel to see its details.
- Use the map's layer controls to add aerials or other layers if they're offered.

Maps vs. surveys
Treat the map as a guide, not a boundary survey: parcel outlines are often shifted a bit from the real corners. A licensed surveyor settles exact lines.
