Knox County, Tennessee GIS Parcel Map Guide
KGIS Maps is the free Knoxville–Knox County parcel viewer. Use it to look up property lines, acreage and owners by address or Map-Group-Parcel ID, then trace the plat at the Register of Deeds.

Knoxville-area people rarely say “the county GIS.” They say KGIS. The Knoxville–Knox County–KUB Geographic Information System is one of the longer-running local GIS partnerships in the Southeast, and its public KGIS Maps viewer is where you look up parcels, owners, and a surprising amount of context about the land.
KGIS: a shared system
KGIS is jointly supported by the City of Knoxville, Knox County, and the Knoxville Utilities Board. That partnership means the parcel layer, address points, and utility-related mapping are maintained together, which keeps the public map consistent across city and county lines. Tennessee also runs a statewide assessment map, but for Knox County the local KGIS viewer is the richer, more current tool.
Find it on the Knox County row of our Tennessee directory, or select the county on the national map.
Search by address, owner or Map-Group-Parcel ID
Tennessee parcel identifiers are built from a tax map number, sometimes a group letter, and a parcel number — so you will see IDs that read like a map reference. Those pieces correspond to the property assessor’s tax maps. If you have a tax notice from the Knox County Trustee, the parcel ID is printed there, and it is the fastest search in KGIS. Our explainer on parcel ID formats covers the idea more broadly.
A five-minute KGIS lookup
- Open KGIS Maps and use the search box for an address, owner, or parcel ID.
- Click the parcel to display its record — owner, acreage, and links to assessment details.
- Switch the basemap to aerial imagery to see structures, tree cover, and access roads.
- Explore the layer list for topography, flood zones, and zoning or planning information if published.
- Record the parcel ID and a dated screenshot before you move on.
Knoxville, Farragut and the acreage in north and east Knox
Knoxville is the county seat and home to the University of Tennessee and TVA’s headquarters. Farragut, the county’s other incorporated town, anchors the west end. Unincorporated communities such as Powell, Halls, Corryton, Mascot, Karns, and Hardin Valley make up much of the rest, and that is where you find more acreage, rolling farmland, and wooded ridge tracts. Oak Ridge and the Great Smoky Mountains foothills are nearby but in other counties, so confirm the county line if a listing is on the edge.
For an acreage map of the county, zoom out in KGIS and switch to aerial imagery. The big irregular parcels in north and east Knox are farms and wooded ridges. Click one and you have the owner of record, which is where a request to hunt or a timber inquiry starts.
Ridges, valleys, and sinkholes
Knox County sits in the Ridge-and-Valley region of East Tennessee. Long parallel ridges — Sharp’s Ridge and Beaver Ridge are well-known local examples — alternate with valleys where roads and neighborhoods follow the low ground. That shape matters on the parcel map: a lot that looks generous from above can be mostly steep hillside. Contour or topography layers help you judge that quickly.
Much of the area is underlain by limestone, and sinkholes are part of the landscape. If you are buying land to build, look for any sinkhole or karst-related information the map offers, and have an engineer or the permitting office weigh in before you design a foundation or septic system.
Finding property lines in Knox County: a four-step approach
- Identify the parcel in KGIS and note its Map-Group-Parcel ID and the deed reference.
- Pull the deed and any recorded plat from the Register of Deeds. Subdivision plats give lot dimensions. Older rural deeds may describe lines by calls to trees, fences and neighbors.
- Turn on KGIS topography. On a ridge, a line that looks short on the aerial may run steeply uphill.
- Look for the iron pins or stones at the corners. If none can be found, hire a surveyor.
How accurate is KGIS?
KGIS is among the more carefully maintained local systems, and in city subdivisions the parcel lines usually track the recorded plats closely. It is still a compiled tax map, not a boundary survey. On ridge-country farms described by old deeds, the drawn line can wander from the true corner, especially along creeks and tree lines. Deeds and plats are recorded with the Knox County Register of Deeds, and the Property Assessor maintains valuations. A Tennessee licensed surveyor sets corners. For neighboring counties, see our Anderson County parcel map guide (Oak Ridge and Clinton) and the statewide Tennessee parcel map guide, or browse the Tennessee county GIS hub.
Lakefront along Fort Loudoun and Melton Hill
Knoxville sits where the Holston and French Broad rivers meet to form the Tennessee River, and TVA reservoirs — Fort Loudoun Lake and Melton Hill Lake — shape the county’s waterfront. On TVA reservoirs, a strip of shoreline may be owned by TVA rather than the adjacent lot owner, and docks and shoreline changes need TVA approval. The parcel map shows the private parcel; it does not settle what you may build on the water side. Check with TVA before you pay a premium for a “lakefront” listing.
Knox County plat book and older maps
You won’t find a current commercial plat book with owner names for Knox County. KGIS fills that role for free, and recorded plats come from the Register of Deeds. For older maps and property history, the Calvin M. McClung Historical Collection at the Knox County Public Library’s East Tennessee History Center and the Tennessee State Library and Archives are good places to ask. Both hold regional map and land-record collections. A Tennessee atlas and gazetteer is great for ridge-country back roads when you go out to look at land.
KGIS not loading, or showing the wrong parcel? Common fixes
- Trusting a mailing address. The owner’s mailing address can be in another state; the situs address is the property location.
- Assuming a city address means city jurisdiction. Many “Knoxville” mailing addresses are in unincorporated Knox County, which affects zoning and some services.
- Reading a steep lot as flat. Aerial photos flatten ridges. Turn on topography before judging a building site.
- Missing a second parcel. Older homes sometimes sit on two tax parcels, or a driveway crosses a separate lot. Click around the edges.
When KGIS itself misbehaves, the fix is usually on your end. Reload in a private window, allow pop-ups so property details can open, and use a desktop browser for the layer list. The Knox County row of our Tennessee directory keeps the current link if the address changes.
Who uses KGIS
Homebuyers comparing west Knox subdivisions, UT-area landlords, builders looking for infill lots in older city neighborhoods, farmers and land buyers in north and east Knox, surveyors, and title examiners. Engineers and utility contractors rely on KGIS’s broader data, but for most residents it is simply the fastest way to see a property line and an owner name together.
Frequently asked questions
What does KGIS stand for?
KGIS is the Knoxville–Knox County–KUB Geographic Information System, a partnership of the City of Knoxville, Knox County and the Knoxville Utilities Board.
What is a Map-Group-Parcel number in Tennessee?
Tennessee parcel IDs combine a tax map number, an optional group letter and a parcel number. The ID is printed on your tax notice and is the fastest way to search KGIS.
Does owning a lot on Fort Loudoun Lake mean I own the shoreline?
Not necessarily. On TVA reservoirs, TVA may own a strip of shoreline, and docks or shoreline changes need TVA approval. Check before you pay a lakefront premium.
Who do I call to find my property lines?
Start with the deed and plat at the Knox County Register of Deeds. For marked corners or a dispute, call a Tennessee licensed land surveyor.

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.
