Ahead of any building plan near Hornbeak, check the Union City zoning map first: the zoning district decides setbacks, lot size and uses. Covered here for Union City: which office sets the rules for a lot, matching a lot to its zoning district, and the questions that save a wasted trip.
Reading the Union City zoning map for one lot
Within municipal limits, the town or city normally writes the zoning code, so property inside Union City is governed there. Past the city line, around Woodland Mills, the county's ordinance, if any, takes over; ask the county planning office to be sure. To find out which side of the line a parcel is on: ask whether the parcel near Obion is inside the boundary.
Getting to the right map
Go first to the Tennessee Property Viewer; it covers every tax parcel around Woodland Mills and Hornbeak. Without an address in hand, pan along US Route 45W and select the outline. For land near Woodland Mills, a pop-up or side panel typically gives the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
Places you'll see on the map
Union City serves as the county seat, home to the main records offices. You'll also find Woodland Mills, Rives, Troy, and South Fulton, each with its own cluster of lots. Around 30,411 people live in Obion County (Census Bureau estimate, 2023) on some 545 square miles. Obion County dates to 1824, which matters when you trace an old farm's title. Places such as Reelfoot National Wildlife Refuge make handy reference points on the map near Rives.
