Who runs this map
Jefferson Parish runs this viewer (directly or through a contracted vendor), which makes it the closest thing to the source for local parcel lines. This site may show a sign-in form first. Look for a guest or public option; if there isn't one, the county office can tell you how to get access.
Finding a property on this map
- Open the official link; the map is hosted on GeoPortal Maps, a vendor platform used by 17 counties in our directory.
- Accept any disclaimer, then use the search tool to find a street address, owner or parcel ID.
- Click a parcel to view its attributes.
- Use the layer or basemap controls to add aerials and other layers where the county provides them.
Many parcel sites expect owner names last name first. If a full name finds nothing, try just the surname.

Before you rely on the lines
The lines you see online are approximate. They're good for finding a lot and its parcel number, but a legal boundary question needs the recorded plat or a surveyor.
