How to use the Williams County plat map
Open the statewide Ohio Statewide Parcels layer in ArcGIS Map Viewer and zoom toward Holiday City; Williams County's parcels are part of that layer. A parcel number from a Williams County tax bill is the most precise search; failing that, an owner name or a click on the map near Holiday City works. Our Williams County listing carries the same link plus neighboring maps.
Behind the map: land records in Williams County

For subdivision lots in Pioneer, the plat book and page on the record leads straight to the recorded plat.
The lay of the land in Williams County

Founded in 1820 and named for David Williams, the county has land records that reach back a long way, which helps when you trace a title. Census Bureau estimates show 36,591 residents in 2023 and around 421 square miles of land in the county. You'll see dense subdivision lots around Bryan and a looser rural pattern in between.
Who uses the Williams County parcel map
- For a house near Pulaski, the parcel record confirms acreage and shows whether the driveway appears to cross another tract.
- Builders bidding a house on a lot in Holiday City start with the parcel ID and legal description, since permit paperwork usually asks for both.
- Raw-land buyers scan Williams County imagery for empty tracts and check the owner records behind them.
- Hunters near Holiday City check the lines before opening day so a blood trail or a retrieve doesn't cross onto a neighbor's ground uninvited.
Acreage and vacant lot search
Try this the next time you're looking for land near Edgerton:
- Zoom out over the countryside around Blakeslee with the aerial layer on, and look for parcels with no structures.
- Click each empty tract near Pulaski and note the owner, acreage and mailing address.
- Measure the road frontage on the map; a sliver of frontage on a road outside Pioneer may not be enough for a driveway permit.
- Size up price by comparing a few similar tracts around Blakeslee on the assessment records.
- Ask the local offices serving Blakeslee about building permits and septic rules before you buy.

Property lines in Williams County, Ohio
Parcel boundaries on the Williams County viewer are drawn to keep tax accounts straight, so small offsets from the true line are expected. Depending on where in Ohio a tract sits, the deed may use a grid or metes and bounds; around Bryan, check the legal description to see which. For walking the corners yourself, our guide to finding property corners helps; for a legal answer, call an Ohio licensed surveyor.
Data limits to keep in mind
If a tract near Edgerton changed hands recently, the recorded deed is more current than the map. For a rural tract near Pulaski, get acreage from a survey, not the tax record, if it matters for a deal.
