Virginia has 95 counties and 38 independent cities — a structure unique among US states (with very limited parallels only in Maryland's Baltimore City, Missouri's St. Louis, and Nevada's Carson City). Virginia's independent cities are not part of any county: they are fully sovereign local governments with their own elected commissioners of the revenue, treasurers, and assessors. When a planner or developer queries parcels in Virginia, the geographic boundary of a county does not enclose its neighboring independent city. Fairfax County and Fairfax City are two legally distinct jurisdictions — different FIPS codes, different assessment offices, different ArcGIS servers. The same is true of Richmond City and the surrounding Henrico and Chesterfield counties. This bifurcation is the most important structural fact about Virginia parcel data: the county REST endpoint does not cover the city within its boundaries.
There is no statewide Virginia parcel REST service. VDOT (Virginia Department of Transportation) publishes a statewide Virginia Parcels Map Service on ArcGIS Hub that aggregates county and city submissions for transportation planning purposes, but it is a cartographic service — it does not expose consistent ownership fields or support reliable owner-name queries. The Virginia Geographic Information Network (VGIN) maintains a statewide GIS clearinghouse and coordinates standards, but cadastral parcel data publication remains the responsibility of each of the 133 local jurisdictions (95 counties + 38 cities). Northern Virginia counties — Fairfax, Arlington, Loudoun, Prince William — tend to maintain the most mature GIS infrastructure. Fairfax County's OpenData ArcGIS server is updated daily and has been publicly accessible since at least 2019. Independent cities in Hampton Roads (Virginia Beach, Norfolk, Chesapeake, Newport News) and the Richmond metro (Richmond City, Petersburg, Hopewell) each maintain their own parcel systems, which must be queried separately.
Virginia's independent city system is not just a legal technicality: it requires a different workflow for any parcel research that crosses political boundaries. A planner studying the Richmond metropolitan area must query Henrico County, Chesterfield County, Hanover County, Richmond City, Colonial Heights, Petersburg, and Hopewell as seven separate jurisdictions, each with its own assessment office and potentially its own ArcGIS endpoint. Norfolk, Virginia Beach, Chesapeake, Suffolk, Portsmouth, and Hampton are all independent cities in the Hampton Roads metro — none of them is inside a county boundary. When building a parcel lookup for a Virginia market area, the first step is to identify which counties and which independent cities fall within the geographic scope of interest, then locate a REST endpoint (or portal fallback) for each jurisdiction separately.
Fairfax County (Northern Virginia, 1.15 million residents) is the most populous jurisdiction in Virginia and one of the most populous counties in the eastern US. Its public ArcGIS MapServer at fairfaxcounty.gov/mercator/rest/services/OpenData/OpenData_A9/MapServer/0 exposes 369,000+ parcel polygons with PIN, PARCEL_KEY, and PARCEL_TYPE (ORDINARY or CONDO). Owner name is not on this public REST layer — it is in a non-spatial CAMA table not accessible via the OpenData endpoint. For owner lookups, the Fairfax County Real Estate Assessment Database at realestate.fairfaxcounty.gov supports search by address, owner name, and parcel ID in a browser interface. Fairfax City, a separate independent city with FIPS 51600, maintains its own assessment records independently of the county.
Fairfax County uses a space-padded PIN with section, block, and lot components — for example, '0304 39 0029'. This format differs from how Fairfax City formats its own parcel identifiers. When querying by PIN and receiving no results, confirm that the PIN format matches the endpoint you are querying: a Fairfax City PIN submitted to the Fairfax County REST endpoint returns nothing, not because the parcel doesn't exist, but because it belongs to a different sovereign jurisdiction. FIPS codes are the reliable disambiguation: Fairfax County is 51059, Fairfax City is 51600.
Northern Virginia's largest jurisdiction (~1.15 million residents). Self-hosted ArcGIS MapServer at fairfaxcounty.gov/mercator. Public parcel layer at OpenData_A9/MapServer/0 exposes PIN, PARCEL_KEY, PARCEL_TYPE, and geometry — no owner name on the REST endpoint. Owner lookups require the browser-based Real Estate Assessment Database at realestate.fairfaxcounty.gov. Updated daily from county cadastral. Fairfax City (FIPS 51600) is a separate independent city with its own assessor — not covered by this county endpoint.
Fairfax County by PIN prefix: www.fairfaxcounty.gov/mercator/rest/services/OpenData/OpenData_A9/MapServer/0/query?where=PIN+LIKE+'0304%25'&outFields=PIN,PARCEL_TYPE,PARCEL_KEY&returnGeometry=false&f=json&resultRecordCount=10. Fairfax by full PIN: ?where=PIN='0304 39 0029'&outFields=*&f=json (use exact space padding). For owner name in Fairfax: realestate.fairfaxcounty.gov (browser only). For independent cities, locate each city's own GIS portal — e.g., Virginia Beach uses vbgov.com/government/departments/gis; Norfolk uses norfolk.gov/gis; Richmond City uses richmondgis.com.

2 Virginia counties are indexed in the UrbanKit atlas with verified public REST endpoints: Fairfax and Prince William. Prince William expose owner-name search; Fairfax index by parcel ID and address only.
Prince William expose an owner-name field on the public REST layer. Prince William, for example, uses the CAMA_OWNER_CUR field — a case-insensitive search is ?where=UPPER(CAMA_OWNER_CUR)%20LIKE%20UPPER('%25SMITH%25')&outFields=*&f=json. Fairfax index by parcel ID and address only, so owner lookups there go through the county assessor or appraiser. Open a county's page here for its full field list and a ready-to-run sample query.
Fairfax publishes parcels at https://www.fairfaxcounty.gov/mercator/rest/services/OpenData/OpenData_A9/MapServer/0 — a MapServer (layer 0). It indexes by Parcel Identification Number and Parcel Key (numeric).
Virginia's indexed counties (Fairfax and Prince William) 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.
