Boone County plat books are an Assessor map tool
Boone County's Assessor points residents to plat books and map viewers, which can help with rural land and ownership research before calling an office.
A Boone County land question does not always need to start at a counter. The Assessor points residents to plat books through the office, as a PDF, and through a map viewer that works on a mobile device or computer.
That is a useful first step in a county where property questions can run from Columbia lots to rural parcels, road frontage, river-bottom land, and places near conservation areas. A plat book or map viewer can help you see the shape of the question before you call.
Keep the limits clear. These tools are for orientation and parcel research. They do not replace a survey, title work, or recorded documents. Use the Recorder when you need recorded papers, and use a surveyor or attorney when a boundary question has legal weight.
