Checking easements on a house in McComb? The McComb plat map is the document to find, since it shows lots, streets and easements as approved. What this McComb guide covers: where plats are filed, plat versus tax map, and the details that matter to buyers.
Getting started with the McComb plat map
For a subdivision near Osyka, look for the plat book reference on the parcel record; bring that to the recorder's office or its online index.
Opening the official parcel viewer
Property in and around Magnolia are published on the MARIS Mississippi Statewide Parcels map viewer, which opens without registering. Near Magnolia, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. If you're looking near Summit, write down the parcel ID from that panel; every office in the county uses it to find the file.
Getting your bearings
Magnolia is the county seat, which is where the courthouse records live. You'll also find Summit and Osyka, where town lots give way to larger tracts. Roughly 39,394 people call Pike County home (Census Bureau estimate, 2023) on some 409 square miles. Pike County dates to 1815, which matters when you trace an old farm's title.
McComb, MS: the basics
McComb lies within Pike County, Mississippi, which means parcel data comes from the county. If you're looking near Summit, the municipality handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Lots just outside the town limits toward Summit often falls under county rules, not municipal ones.
Amended plats
Lots near Magnolia can be combined or reconfigured by a replat, search the index for replats of the same subdivision; vacated streets or alleys also get recorded.

Legal descriptions in Mississippi

A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though sections near Summit can be irregular. Write down the legal description for the tract near Magnolia when you talk to a surveyor.
Limits of the parcel data
Acreage on the record is an assessed number; only a licensed surveyor establishes the real boundary for a parcel near Summit. If the land is near Osyka, records update in batches, so a deed recorded last month can take weeks to appear.
When a parcel crosses a boundary
Pike County meets Tangipahoa Parish, LA, Washington Parish, LA, Amite County, Lincoln County, and Walthall County, all with their own assessor records. Ground near Summit that runs to the line can be split in two county records, so check the adjacent map before you assume the acreage.

Getting a copy
For a home near Magnolia, some counties put plat images online, otherwise call or visit with the reference; small fees are common.
Field tips
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Osyka, but coverage can be spotty out of town. A screenshot of the parcel near Osyka with its ID is a good backup.
Deeds, plats and who keeps them
The map is an index, not the title: deeds, subdivision plats and easements covering ground around Magnolia sit with the Chancery Clerk. Long-held tracts around Summit can trace back through several deeds, so a title company can sort it out before a purchase.
Land outside a subdivision
Rural land near Summit that was never subdivided is often described by metes and bounds or survey description; the deed and any recorded survey describe it instead.
Who handles what
Recorded documents for a parcel near Osyka come from the Chancery Clerk, usually searchable by name or document number. Zoning, permits and septic questions near Magnolia go to planning, building or health offices, town or county, depending on location.
