Where Adams County deeds and plats are kept

What the map covers, from Quincy to the back roads
Quincy serves as the county seat. Crossroads communities such as Adams, Beverly, and Bloomfield have their own small clusters of lots. The county dates to 1825, named for John Quincy Adams, and older deeds may still refer to landmarks from that era. Census Bureau estimates show 64,441 residents in 2023 and around 855 square miles of land in the county. Between Bloomfield and Beverly the map alternates between platted subdivisions and open farm or wooded tracts. On the parcel layer, Great River National Wildlife Refuge shows up as public ground, and the private tracts along its edges are worth checking line by line.
Who needs this map
- House hunters looking at Quincy use the parcel record as a free check on the listing: lot size, legal description and last recorded sale.
- A small builder looking for spec lots around Beverly can scan the map for vacant parcels in already-platted subdivisions.
- Unlisted land near Quincy sometimes turns up this way: an empty parcel, an absentee owner, and a polite letter.

Rural Adams County land sits on the federal survey grid: a deed might call out a quarter of a numbered section in a given township and range. A survey is the only document that settles where an Adams County boundary actually runs.
Before you rely on the data
