Databases & Maps
Real Estate Assessment - The property information made available on this site includes ownership and deed information, legal description, sales information, assessment values and house characteristics and can be searched by Parcel ID Number, Address and Tax Map Number. Parcels are linked to the Loudoun County GIS, with map overlays displaying boundary and environmental information such as topography, soils, flood plain and major roads.

GIS Mapping Database - WebLogis is an interactive mapping system that accesses the county’s Geographic Information System (GIS) directly. Data layers are updated on differing schedules, though addresses, parcels, and streets are updated daily. The mapped information on the site reflects the information on the GIS from the previous day.
