Ascension Parish at a glance: towns and land

You'll also find unincorporated communities, among them Darrow, Lemannville, and Prairieville. The parish was organized in 1807 and named for Ascension of Jesus Christ, so some tracts carry a long chain of deeds. About 131,632 people lived in Ascension Parish in 2023, according to Census Bureau estimates, on roughly 290 square miles. Built-up areas around Donaldsonville mean most clicks land on platted lots; larger undeveloped tracts are rarer and get attention fast.
Property lines in Ascension Parish, Louisiana
On rural tracts near Acy, the parcel lines can drift from the fences on the ground, sometimes by more than a few feet. Square-ish tracts around Donaldsonville are no accident: Louisiana land was surveyed into sections, and deeds still describe land that way. Planning a fence or shed on a lot in Donaldsonville? Have a Louisiana licensed surveyor mark the corners first.
Using the Ascension Parish plat map to find vacant land
To use the Ascension Parish plat map for a vacant land search:
- Run the aerial layer along I-10 and the side roads off it, flagging any tract with no structures.
- For each tract near Donaldsonville, note the parcel ID, the owner and where the tax bill is mailed.
- Measure the road frontage on the map; a sliver of frontage on a road outside Donaldsonville may not be enough for a driveway permit.
- Assessed values lag the market, but comparing tracts near Acy still shows which ones the parish rates higher.
- Before you sign for land near Sorrento, check what the local planning and health offices will allow on it.
Before you buy near Gonzales, read how to tell if land is buildable.

If you're comparing land near Sorrento with land near Gonzales, the local job base is part of the price story.
Where Ascension Parish deeds and plats are kept
Think of the parcel layer as a pointer: it tells you which deed or plat to request from the parish's recording office. Recording offices go by different titles from state to state, including register of deeds, recorder, county clerk and clerk of court; the official Ascension Parish website names the one that handles deeds. Copy the parcel ID and legal description before you call or visit; recording staff can find an Ascension Parish document much faster with them.
Parcels that cross a parish line
Tracts near the parish line can be tricky. Neighbors include Assumption Parish, East Baton Rouge Parish, Iberville Parish, Livingston Parish, and St. James Parish, and each keeps its own parcel map, so a farm that straddles the line shows up in two places. Our Louisiana directory links each one.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
