Tennessee property assessment is the responsibility of the county Assessor of Property — a title specific to Tennessee state law. The Tennessee Comptroller's Office sets assessment standards and publishes some statewide property data through the Division of Property Assessments, but county parcel GIS layers are published independently by each of Tennessee's 95 counties. The atlas covers three counties: Davidson (Nashville), Shelby (Memphis), and Hamilton (Chattanooga). These three represent Tennessee's three largest metros and each operates its own GIS infrastructure under a distinct institutional arrangement: Davidson is a consolidated city-county, Shelby runs a regional GIS operation called ReGIS, and Hamilton County publishes from a mapsdev subdomain with a live data feed from the assessor.
The Tennessee Geographic Information Council (TNGIC) coordinates GIS standards across state agencies but does not aggregate county parcel data. TN.gov maintains some statewide data through the Tennessee Advanced Spatial Information System (TASIS), and the Tennessee Comptroller provides assessment data downloads through the Division of Property Assessments, but neither provides a unified public parcel REST service. Each county Assessor of Property is the institutional data owner. Davidson County (Nashville) is a consolidated city-county, so Metro Nashville GIS serves both city and county planning functions. Shelby County's ReGIS (Regional Geographic Information Systems) program serves the Memphis metro including multiple municipalities — Bartlett, Collierville, Germantown, Lakeland, and Millington — through a single CurrentParcels layer, which makes it unusual among Tennessee counties.
Davidson County (Nashville) is a consolidated city-county government. Its parcel layer exposes both APN (Assessor Parcel Number, the county's primary parcel key) and STANPAR (State Parcel Number, the identifier used in state-level reporting). These two identifier fields can differ in format; STANPAR is typically the reference when cross-referencing against Tennessee Comptroller assessment data. The layer also exposes LUCode and LUDesc (land use code and description), which Nashville uses for zoning and planning analysis. A separate Parcels_SP service exists at the same path with a State Plane spatial reference for projects requiring that projection.
Hamilton County Tennessee's parcel layer is at mapsdev.hamiltontn.gov — the 'mapsdev' subdomain suggests a development or staging context, but this is the production endpoint that the county publishes. The service name is Live_Parcels, which reflects a real-time or near-real-time feed from the county Assessor of Property's CAMA system. The primary identifiers are PBA_NUM (Parcel Book Account Number, formatted as '033006 00302P000' with internal spaces) and GISLINK (the trimmed parcel ID used in GIS context). Hamilton County TN (FIPS 47065, Chattanooga) is entirely distinct from Hamilton County OH (FIPS 39061, Cincinnati) and Hamilton County IN (FIPS 18057, Indianapolis north suburbs).
Shelby County's CurrentParcels layer serves parcels for all of Shelby County, which includes Memphis city parcels alongside parcels in the unincorporated county and six suburban municipalities. The MUNI field identifies the municipality: Memphis, Bartlett, Collierville, Germantown, Lakeland, Millington, and unincorporated Shelby County. Queries that filter by MUNI can isolate a single jurisdiction without needing a separate spatial boundary layer. The layer exposes both PARCELID (the formatted parcel ID) and PARID (the CAMA account ID), which serve different lookup purposes in the county's back-office systems.
Contains Nashville (consolidated city-county, pop. 715,000). 57-field layer at maps.nashville.gov. Exposes Owner, PropAddr, APN, STANPAR, LandAppr, ImprAppr, TotlAppr, and SalePrice. A separate Parcels_SP service covers the same data in State Plane projection.
Contains Memphis metro (pop. 934,000 county). ReGIS CurrentParcels layer covers all Shelby County municipalities. MUNI field identifies jurisdiction. 47 fields including PARCELID, PARID, OWNER, PAR_ADDR1, OWN_ADDR1, NBHD, CLASS, LUC, ZONING.
Contains Chattanooga (pop. 375,000 county). This is Tennessee's Hamilton County (FIPS 47065), distinct from Ohio's Hamilton County (FIPS 39061) and Indiana's Hamilton County (FIPS 18057). Endpoint at mapsdev.hamiltontn.gov/hcwa03. Live_Parcels service feeds directly from Assessor CAMA. Primary identifiers: PBA_NUM and GISLINK.
Davidson County owner query: ?where=UPPER(Owner)+LIKE+UPPER('%25SMITH%25')&outFields=ParID,Owner,PropAddr,PropCity,APN,TotlAppr,SalePrice&f=json.

3 Tennessee counties are indexed in the UrbanKit atlas with verified public REST endpoints: Davidson, Shelby, and Hamilton. Each exposes an owner-name field you can search directly on the public layer.
Davidson, Shelby, and Hamilton expose an owner-name field on the public REST layer. Davidson, for example, uses the Owner field — a case-insensitive search is ?where=UPPER(Owner)%20LIKE%20UPPER('%25SMITH%25')&outFields=*&f=json. Open a county's page here for its full field list and a ready-to-run sample query.
Davidson publishes parcels at https://maps.nashville.gov/arcgis/rest/services/Cadastral/Parcels/MapServer/0 — a MapServer (layer 0). It indexes by Parcel ID, Owner Name, Owner Address 1, and Property Address. Owner-name search: UPPER(Owner) LIKE UPPER('%25SMITH%25').
Tennessee's indexed counties (Davidson, Shelby, and Hamilton) publish county-hosted ArcGIS MapServer layers. MapServer supports the same /query operation for owner, parcel-ID, and address lookups as FeatureServer — for read-only parcel lookups the two are interchangeable.
