Next: the Union County viewer link, a quick look at Hemby Bridge and the surrounding land, and how North Carolina records back up the map.
Getting oriented in Union County
The county seat is Monroe; Fairview, Hemby Bridge, Indian Trail, and Marshville are among the other communities you can zoom to. The Census Bureau puts Union County at about 633 square miles of land and an estimated 256,452 people (2023). Subdivision plats fill most of the map near Fairview; open acreage survives mainly at the edges of the county.
The Union County economy in brief
By the Census Bureau's 2022 count, 5,582 business establishments operated in Union County. Construction had the most, followed by professional and technical services and retail trade. Measured against national shares, textile mills, nonmetallic mineral product manufacturing, and heavy and civil engineering construction are overrepresented in Union County. Small acreage near Marshville can appeal to buyers who work at the county's plants and want room outside town. For a land buyer in Union County, that mix hints at who your neighbors and competing bidders are likely to be.
Opening the Union County GIS map
Start with the Union County parcel viewer; it opens in a normal browser with no sign-in. A parcel number from a Union County tax bill is the most precise search; failing that, an owner name or a click on the map near Fairview works. If the official link ever moves, the Union County page on Platbookmapper keeps the current version.
Acreage and vacant lot search
A practical way to find vacant parcels near Marshville:
- Turn on the photo basemap and work outward from Marshville one road at a time, flagging parcels with no buildings.
- Build a short list of open parcels around Marshville with owner names and acreage before you make any calls.
- Size up price by comparing a few similar tracts around Marshville on the assessment records.
- Measure the road frontage on the map; a sliver of frontage on a road outside Mineral Springs may not be enough for a driveway permit.
- Rural lots near New Salem may need a septic permit and a well, so ask before you commit.
Before you buy near Marshville, read how to tell if land is buildable.
Who uses the Union County parcel map
The same map serves very different jobs around Hemby Bridge. Contractors working in Union County use the map to find lot dimensions and neighboring owners before they stake a foundation or schedule a survey. House hunters looking at Marshville use the parcel record as a free check on the listing: lot size, legal description and last recorded sale. Folks shopping for raw land click through empty parcels near Hemby Bridge, note the owners, and send letters. An owner in Fairview planning a fence or an outbuilding pulls the parcel first, then the recorded plat.
How to find property lines in Union County
A Union County GIS map is built for assessment, not construction. In Union County, as in most places, the lines are a best fit of old deed calls onto modern aerial photos. North Carolina is a metes-and-bounds state. Rural deeds in Union County describe boundaries with bearings, distances and landmarks rather than a square grid, so parcel lines are often irregular. Planning a fence or shed on a lot in Hemby Bridge? Have a North Carolina licensed surveyor mark the corners first.
Behind the map: land records in Union County
Need a deed for land near New Salem? In North Carolina that means the Register of Deeds; the parcel map is the index that points you there. For a lot near Stallings, the recorded plat and deed are with the Union County Register of Deeds. The parcel record often lists a deed book and page or an instrument number, which is how you request a copy of the recorded deed for a tract near Mineral Springs.

Frequently asked questions
How do I find property lines in Union County?
Find the tract near Hemby Bridge on the parcel map, note the legal description, and compare it with the recorded deed. If you need certainty, a North Carolina licensed surveyor can stake the corners.
Does Union County charge for its property map?
Free. The Union County map is a public record tool, and no sign-up is needed.
Can I trust the acreage on the Union County map?
Close enough to screen a tract near New Salem, not close enough to price it by the acre. Use a survey for that.

Click the parcel. Union County tax records show the owner of record and usually a mailing address, which may differ from the property address.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
