New Castle County Parcel and Property Records
The county parcel search sits at www3.newcastlede.gov/parcel/search. It is free and open around the clock. You can look up property by tax parcel number, street address, owner name, deed book, subdivision, or lot number.
Search tips help. Do not enter suffixes like Road, Lane, or Avenue in the street field. Skip directions, apartment numbers, and unit numbers in the address line. Numbered streets need to be spelled out. Type "TWENTY FIFTH" instead of 25th. Parcel numbers must be digits only with no dashes or dots.
Results show current ownership, past owners, assessment values, tax status, recorded deeds and mortgages, and building permit history. The property survey data is linked in many records.

The portal above is the daily workhorse for county real estate data. Title agents, brokers, appraisers, and homeowners all use it.
Property assessments are set by the Assessment Division. The office is at 87 Reads Way, New Castle, DE 19720. Call (302) 395-5520 for appeal questions or to confirm values.

The county's Geographic Information System lives at the GIS Services hub. It layers parcel data on top of maps for research.
The hub shows zoning, flood zones, school boundaries, and aerial imagery. You can measure distance, draw custom maps, and export data. A second portal called FirstMap GIS is also helpful for name-by-address lookups.
Data layers available in the New Castle County GIS system:
- Parcel boundaries and ownership

- Flood zone designations
- School district boundaries
- Aerial imagery from multiple years
- Infrastructure locations

The GIS hub lets anyone build a quick snapshot of a property or neighborhood. It pairs well with the parcel search when you need both numbers and a visual.
