The Blount County tax map shows the location, boundaries, size, and appraised value of every taxable parcel in the county. You can view it online through the county’s GIS portal or in person at the Property Assessor’s office in the Blount County Courthouse in Maryville. Searching by parcel identification number pulls up the exact record; address and owner name also work, with occasional duplicates.
Ways to Search a Parcel
Three identifiers will find a property on the Blount County tax map. Street address is the easiest if you have it. Owner name works too, though common names can return several results and send you clicking through to confirm you have the right tract.
The most precise identifier is the parcel ID, which follows a Map-Group-Parcel format unique to each tract in the county. It appears on your annual property tax bill and in the legal description recorded with your deed. Entering the parcel ID bypasses any confusion from similar addresses or shared names and is the fastest route to the correct record.
Using the Online GIS Portal
Blount County runs an interactive mapping application linked from its government website’s maps page.1Blount County, TN. Maps The Blount County GIS group also publishes PDF versions of individual tax maps at a separate site.2Blount County GIS. Blount County GIS The interactive version is the one most people want; the PDFs are useful when you need a clean image of a specific map sheet.
Once the application loads, type your search into the bar at the top. The map zooms to the parcel and outlines it. You can drag to pan across the county, zoom with on-screen buttons or a scroll wheel, and click any highlighted parcel to open a popup of basic property information. Nothing about the tool is particularly technical, and you can learn its quirks in a few minutes without ever opening help documentation.
What Each Parcel Record Shows
Clicking a parcel pulls up acreage, boundary dimensions, and the appraised value broken out between land and any structures on it. The owner’s name, mailing address, and the property’s assessment classification (residential, commercial, or agricultural) also appear.
Beyond the parcel data itself, the portal lets you turn optional map layers on and off:
- Aerial photography shows actual ground conditions and buildings.
- Topographic overlays show elevation changes relevant to drainage and construction.
- Flood zone layers, drawn from FEMA’s Flood Insurance Rate Maps, mark whether a parcel sits in a Special Flood Hazard Area where a lender will require flood insurance.
- Zoning layers show what the county permits on the tract.
Stacking these layers over the parcel lines gives you a working picture of both what the land legally is and what it physically looks like. Owners frequently use the comparison this way: pull up several similar neighboring tracts and see whether their own appraised value lines up with what the assessor has placed on comparable property nearby.
Reading the Appraised Value
The appraised value on the tax map is not the number the county taxes. Tennessee applies an assessment ratio first. Residential property and farmland are assessed at 25% of appraised value; commercial and industrial property at 40%.3Blount County, TN.

If the Map Value Looks Wrong
The comparison tools on the GIS portal are worth their weight when a value looks off. Pulling up neighboring parcels with similar square footage, acreage, and condition gives you concrete evidence to bring to the assessor.
Start informally: contact the Blount County Property Assessor’s office and talk through the issue. If that doesn’t resolve it, file a formal appeal with the county board of equalization. With limited exceptions, you must begin at the county level or the assessment becomes final.6Tennessee Comptroller of the Treasury. Value Appeals
If the county board rules against you, the next level is the State Board of Equalization. The deadline is August 1 of the tax year or 45 days after you receive the county board’s decision, whichever is later, with an absolute cutoff of March 1 of the following year, after which the State Board loses jurisdiction.6Tennessee Comptroller of the Treasury. Value Appeals A few narrow situations let you skip the county board, the most common being an assessor’s failure to send proper notice of a change in your assessment or classification.
