What PlatBook holds for Delaware County

How to look up a Delaware County parcel

  1. By parcel number. Type the Delaware County parcel ID exactly as the county prints it, with or without hyphens.
  2. By owner name. Last name first works, and so does a company name. Names are normalized from the tax roll, so "SMITH JOHN A" is shown as "John Smith".
  3. By street address. House number and street is enough; the city is optional.

Every result opens a parcel card with the owner, the situs address, the land use and acreage, the current assessed value, and a direct link to the Delaware County Auditor's own record for the same parcel.

Think the value is wrong?

Any Delaware County owner can ask the county Board of Revision to lower the county's value, using DTE Form 1, free, by March 31. What decides those cases is evidence of what the property is actually worth, not an argument that the taxes are too high. See how to file in Delaware County: where the complaint goes, whether the county takes an electronic filing, and whether the form must be notarized. Or read the statewide guide to Ohio Board of Revision complaints.
