Opening the Opelousas GIS map
In most places the county maintains the parcel layer, so for Opelousas the go-to is the St. Landry Parish parcel viewer.
Getting to the right map
Go first to the St. Landry Parish parcel viewer; it maps every tax parcel in the parish, Grand Coteau included. For land near Arnaudville, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. Save the parcel ID before closing the panel; every clerk in the parish asks for it first.
Places you'll see on the map
Opelousas holds the county offices, where most land records are kept. Other places on the map include Washington, Leonville, Grand Coteau, and Port Barre. About 81,464 people live in St. Landry Parish (Census estimate, 2023) spread over roughly 924 square miles. St. Landry Parish dates to 1807, so old deeds can run back a long way. Landmarks such as Atchafalaya National Wildlife Refuge make handy reference points on the map near Leonville.
Field tips
Most viewers work in a phone browser, useful out on a road near Sunset, but coverage can be spotty out of town. A screenshot of the parcel near Port Barre with its ID keeps working without signal.
Limits of the parcel data
The acreage figure is an estimate; only a licensed surveyor can set the real lines for a parcel near Arnaudville. Near Washington, records update in batches, so a deed recorded last month can take weeks to appear.
Troubleshooting the viewer
When the map won't open around Washington, switch browsers or turn off pop-up blockers; links occasionally change, and our directory page keeps the current one.
How land is described here
Louisiana is laid out under the Public Land Survey System, which means a tract near Grand Coteau is described by section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though real sections near Arnaudville vary in size. Write down the legal description for the tract near Arnaudville for any title or survey request.
Opelousas and the county around it
The town is part of St. Landry Parish, Louisiana, so its parcels are on the county's map around Eunice. Opelousas is also the county seat, so deeds and plats are filed in town. For property near Port Barre, city or town hall handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Acreage past the city limits toward Washington generally follows county rules rather than the town's.
Land on the parish line
St. Landry Parish touches Acadia Parish, Avoyelles Parish, Evangeline Parish, Lafayette Parish, and Pointe Coupee Parish; every one of them runs a separate parcel map. Acreage along the edge near Leonville may be split in two parish records, so check the adjacent map too. Around Port Barre, our state page lists each neighboring parish map for Louisiana.
Three ways to find a parcel
For a house in Opelousas, search the street address; for owner searches, try last name first. For a tract near Sunset, searching by parcel number never misses, and you'll find it on tax statements.
Which office to call
Deeds, mortgages and recorded plats for land near Grand Coteau come from the Clerk of Court, sometimes only in person. Zoning, permits and septic questions near Arnaudville go to planning, building or health offices, town or parish, depending on location.

Backing up the map with records

Printing and saving
