Louisiana Parcel Maps & Parish GIS Viewers
Louisiana uses parishes, not counties. This hub lists official parish GIS and assessor viewers so you can open the local tax map under the right parish name.
We link out — we do not host parcels. Platbookmapper does not draw lot lines, embed county FeatureServers, or redistribute tax-parcel geometry for Louisiana. Our role is to connect you to the official county GIS / parcel viewer that maintains the property information. Not a survey product.
Parish parcel search (not counties)
We link out to official parish sources and never host Louisiana parcel geometry. Choose a parish from the list, open its GIS or assessor app, then search by address, assessment account, or owner. Coastal and wetland parishes often expose flood and levee-related context; northern parishes emphasize timber and ag tracts.
Louisiana’s civil-law heritage and French/Spanish grant history mean parcel identifiers and legal descriptions can look different from PLSS states. Municipalities sit inside parishes—search the parish that assesses the property. Waterbottoms and coastal erosion notes may appear near parcels; treat those as planning context, not a substitute title opinion.
Tax layers are not surveys. Verify boundaries with recorded documents or a Louisiana licensed surveyor.
Searching “county” terminology will fail—stick to parish names on this hub. Coastal parish viewers may lag after storms; if a lot looks wrong, confirm with the assessor’s office rather than a screenshot from an unofficial mirror. We do not mirror parish layers.

Frequently asked questions
How do I find a Louisiana county parcel map?
Pick your county on this Louisiana hub (or on the national Platbookmapper map), then open the official GIS / parcel viewer link. Each county maintains its own app — we link out and do not host parcels.
Are Louisiana online parcel maps survey-grade?
No. County GIS parcels are tax and planning layers. For legal boundaries, use a recorded plat or hire a licensed surveyor.
Why do some Louisiana counties say Verify via map?
We only mark a county Listed when we have a curated direct interactive viewer URL. Verify counties still open from the national map with the best available outbound link — always confirm it is the official local source.
Does Platbookmapper draw property lot lines?
No. We do not host or redraw parcel geometry. Our product is a USA → county → official GIS link directory so you can open the local interactive map in a new tab.
