Searching for a parcel, step by step

  2. Search by street address, owner or parcel ID if the search box offers those options.
  3. Click a lot on the map to read its attributes.
  4. Turn on aerial imagery from the basemap tool and use the layer list to add things like zoning or flood zones when they're published.

Have a tax bill handy? The parcel or account number on it is usually the fastest way to search.

A note on accuracy

The lines you see online are approximate. They're good for finding a lot and its parcel number, but a legal boundary question needs the recorded plat or a surveyor.
