Where the Marietta GIS map lives
In and around Mableton, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
Pulling up a parcel
Go first to the Cobb County ArcGIS parcel map; it maps each tax parcel from Powder Springs to Mableton. If you're looking near Austell, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. If the land is near Mableton, write down the parcel ID while you have it open; each records desk in the county asks for it first.
Places you'll see on the map
Marietta holds the county offices, home to the main records offices. You'll also find Smyrna, Kennesaw, Mableton, and Powder Springs, where town lots give way to larger tracts. Around 776,743 people call Cobb County home (Census estimate, 2023) across some 340 square miles. Cobb County was formed in 1832, and some chains of title near Acworth are long. Features like Noonday Creek, Allatoona Creek, and Chattahoochee River National Recreation Area make handy reference points on the map near Austell.
Using it on a phone
The parcel map usually runs in a mobile browser, useful out on a road near Smyrna, but coverage can be spotty out of town. A screenshot of the parcel near Smyrna with its ID helps when you meet an owner or agent.

Who handles what

Marietta and the county around it
The city sits in Cobb County, Georgia, which means parcel data comes from the county, at least around Smyrna. As the county seat, Marietta hosts the courthouse, so deeds and plats are filed in town. For property near Kennesaw, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Lots just outside the town limits out by Kennesaw generally falls under county rules instead.
Finding the right lot
Acreage around Kennesaw might not have a street number, which means panning to it and clicking. For a home near Austell, searching by parcel number never misses, and it's printed on tax bills.
Aerials, labels and overlays
Switch to the aerial basemap over the city shows roofs, driveways and tree lines next to the parcel edges, at least around Kennesaw.
Before you lean on the lines
Parcel lines are drawn for taxes, not measured on the ground, so a fence near Smyrna can sit a few yards off the line on screen. For property near Kennesaw, records update in batches, so a deed recorded last month can take weeks to appear.
What the record panel tells you
Recent sales on nearby lots in Marietta are a useful starting point; an appraiser is the real authority.
Recorded documents worth pulling
The map is an index, not the title: deeds, subdivision plats and easements for land near Acworth are filed with the Clerk of Superior Court. Long-held tracts around Kennesaw may sit on many deeds, and a title company can sort it out before a purchase.
Land on the county line
Cobb County meets Bartow County, Cherokee County, Douglas County, Fulton County, and Paulding County; every one of them runs a separate parcel map. A tract near the line by Kennesaw can show up across two assessors' files, so look at the neighboring map as well. For land near Powder Springs, our state page links every neighboring county map across Georgia.
