Looking for a Worth County plat book? These atlases map who owns rural land, page by page, and it's handy for land around Prohibition City. In this county guide: what's in a plat book, where to look for printed copies, and the free online map that stays current around Grant City.
The Worth County plat book: start here
If you're looking near Grant City, a plat book is a privately published atlas, with owner names on each tract, often organized by township.
The free map to start with
Your first stop is the IntegrityGIS - Worth County; it maps every assessed parcel around Isadora and Grant City. For land near Defiance, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. If you're looking near Defiance, copy the parcel ID while you have it open; every records desk in the county asks for it first.
Legal descriptions in Missouri
Missouri is laid out under the Public Land Survey System, so deeds around Irena reference sections and townships. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Prohibition City can be irregular. Keep the legal description for land near Prohibition City when you talk to a surveyor.
When a parcel crosses a boundary
The county borders Ringgold County, IA, Taylor County, IA, Gentry County, Harrison County, and Nodaway County, and each of those keeps its own parcel map around Sheridan. Ground near Irena that runs to the line may show up across two assessors' files, so check the adjacent map too. On ground around Denver, the Platbookmapper state page links each neighboring county map across Missouri.
Common uses
Farmers, hunters and appraisers near Sheridan use plat books to see ownership across many tracts at once.
Getting answers from the right desk
If the acreage or value on a parcel near Isadora looks off are handled by the County Assessor, the office behind the parcel record. Questions about what you can build around Irena go to planning, building or health offices, town or county, depending on location.
Printing your own
Screenshot each section of the viewer around Defiance and keep them in a binder for the truck.
Deeds, plats and who keeps them
When the details count, get the recorded deed from the Recorder of Deeds; the parcel line is a drawing of it, and that holds around Allendale too. Closer to Defiance, bring the document number listed on the parcel record to skip a name search.
Finding a printed edition
Older editions near Irena turn up in libraries and historical societies, which helps when tracing a farm's history.
Before you lean on the lines
Listed acreage is an assessed number; only a licensed surveyor sets the real boundary for a parcel near Oxford. In and around Sheridan, records update in batches, so a deed recorded last month can take weeks to appear.
On site with the map
The parcel map usually runs in a mobile browser, useful out on a road near Defiance, though signal can drop in rural spots. A saved image of the lot near Allendale and its lines keeps working without signal.
Between editions
The IntegrityGIS - Worth County is updated more often than any atlas, including rural land around Oxford.
Places you'll see on the map
Grant City is the county seat, where most land records are kept. You'll also find Sheridan, Allendale, Denver, and Irena. Around 1,907 people call Worth County home (Census estimate, 2023) spread over about 267 square miles. Worth County was organized in 1861, which matters when you trace an old farm's title.
Two kinds of plat
For land near Irena, don't confuse the atlas with a recorded subdivision plat: the recorded plat at the Recorder of Deeds is a legal document, and the atlas is just a guide.
