Where the parcel data comes from
This is a statewide map, not a county site. Delaware FirstMap State Parcels covers parcels across Delaware, and Kent County is one part of it. Statewide parcel layers are usually stitched together from county files, so the newest splits or sales may show up on the county's own records first. As of our October 2026 test, anyone could open it without signing in or paying.
How to use the Kent County viewer
- Open Delaware FirstMap State Parcels in a new tab and zoom to Kent County (around Dover).
- Type a street address into the search box, or click directly on a parcel.
- Review the parcel attributes; field names vary by state.
- Confirm anything important with the county assessor, since the statewide layer is a compiled copy.
Have a tax bill handy? The parcel or account number on it is usually the fastest way to search.
