What the map covers, from New Orleans to the back roads
Besides New Orleans, which serves as the parish seat, the map covers Algiers, Carrollton, Irish Bayou, and McDonoghville. By Census Bureau figures, the parish had roughly 364,136 residents in 2023, spread over about 169 square miles of land. Subdivision plats fill most of the map near Algiers; open acreage survives mainly at the edges of the parish. Waterfront and bottomland parcels near Lake Pontchartrain and Lake Borgne deserve a second look at the flood layer.

Accommodation and food services had the most, followed by professional and technical services and retail trade.

A buyer looking for a cabin lot near Irish Bayou may find recreation buyers in the mix too. Keep that in mind when you compare parcels in Orleans Parish: who works here shapes what land sells.

Acreage and vacant lot search
Looking for open ground between New Orleans and Irish Bayou? Try this:
- With imagery on, zoom to the edge of New Orleans where subdivisions give way to open ground.
- Check who owns each open tract near Grand Isle and where the tax bill goes.
- Assessed values lag the market, but comparing tracts near Irish Bayou still shows which ones the parish rates higher.
- Check that the tract touches a public road; a landlocked lot near New Orleans can be hard to finance and build on.
- Last, call the Orleans Parish planning or health office about permits, septic and floodplain before you commit.
For a tract near Irish Bayou with no road frontage, see how to tell if land is landlocked.

Have a Louisiana licensed surveyor mark the corners first.
Where Orleans Parish deeds and plats are kept
Every line on the Orleans Parish map traces back to a recorded deed or plat, and the parish's recording office keeps those documents. Recording offices go by different titles from state to state, including register of deeds, recorder, county clerk and clerk of court; the official Orleans Parish website names the one that handles deeds. Easements and rights-of-way are usually in recorded documents, not on the parcel map, so read the deed itself for a tract near Irish Bayou.
Near the parish line
