If a legal description for land in Hammond cites a lot number, you'll need the Hammond plat map to make sense of it. This Hammond guide covers: where plats are filed, plat versus tax map, and the details that matter to buyers.
The Hammond plat map: start here
The Clerk of Court files approved subdivision plats, with a book and page or instrument number.
The free map to start with
Go first to the Tangipahoa Parish parcel viewer; it maps every assessed parcel in the parish, Ponchatoula included. For a tract near Roseland, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. Copy the parcel ID before closing the panel; each records desk in the parish uses it to find the file.
Offices that can help
If the acreage or value on a parcel near Ponchatoula looks off go to the Parish Assessor, which maintains the tax roll. Building or septic questions for a lot near Tickfaw are for the local planning and health departments, town or parish, depending on location.
When a plat changes
Lots near Roseland can be combined or reconfigured by a replat, so check for later filings; street vacations near Amite City show up in the records too.
How land is described here
Louisiana uses the Public Land Survey System, so deeds around Ponchatoula reference sections and townships. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though corrections make some sections near Tickfaw odd-sized. Keep the legal description for land near Ponchatoula for any title or survey request.
Metes and bounds instead
Acreage around Kentwood outside a subdivision is often described by metes and bounds or survey description; the deed and any recorded survey describe it instead.
Hammond, LA: the basics
Hammond lies within Tangipahoa Parish, Louisiana, which means parcel data comes from the county. With a lot near Roseland, City or town hall handles matters such as zoning, permits and utilities inside its limits, while the county keeps the tax map. Land beyond the town limits out by Ponchatoula often answers to county rules, not municipal ones.
Land on the parish line
Tangipahoa Parish borders Jefferson Parish, Livingston Parish, St. Charles Parish, St. Helena Parish, and St. John the Baptist Parish; every one of them runs a separate parcel map. A tract near the line by Tickfaw may be split in two parish records, so look at the neighboring map as well. If the land is near Amite City, our state page lists every neighboring parish map across Louisiana.
Where the recorded documents are
Before you sign anything, get the recorded deed from the Clerk of Court; the parcel line is a drawing of it. Older tracts in the parish can sit on many deeds, so a title company is worth hiring on a real sale.
Field tips
The parcel map usually runs in a mobile browser, useful out on a road near Amite City, but coverage can be spotty out of town. A screenshot of the parcel near Tickfaw with its ID keeps working without signal.
Two different maps
The Tangipahoa Parish parcel viewer draws parcels for taxes, but the recorded plat is what the deed relies on.
What a plat shows
Easements on the plat near Ponchatoula limit where you can build or fence; read the notes on the sheet.
Tangipahoa Parish in a few facts
Amite City holds the county offices, where most land records are kept. You'll also find Ponchatoula, Tickfaw, and Independence, each with its own cluster of lots. Around 138,064 people live in Tangipahoa Parish (Census Bureau estimate, 2023) across roughly 791 square miles. Tangipahoa Parish was formed in 1869, which matters when you trace an old farm's title. Features like Lake Pontchartrain make handy reference points on the map near Tickfaw.
What the map can't tell you
The acreage figure is an estimate; just a licensed surveyor establishes the real lines for a parcel near Roseland. For property near Kentwood, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Requesting the plat
On ground around Tickfaw, some counties put plat images online, otherwise call or visit with the reference; small fees are common.

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.
