Searching for a parcel, step by step
- Open the official link in a new tab.
- 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.
Many parcel sites expect owner names last name first. If a full name finds nothing, try just the surname.
