The Cobb County Fence-Line Mistake That Can Blow Up a Closing

The fence looks permanent. The neighbors have never complained. The shed has been there for years, and the driveway has always curved across the same strip of grass.

Then a survey arrives—and part of the property story changes.

A fence crosses the boundary. A retaining wall sits inside an easement. A pool deck reaches beyond a setback. A neighbor’s driveway clips the corner of the lot. Suddenly, a feature everyone treated as ordinary becomes a title, lending, insurance or negotiation problem days before closing.

This is one of the most underestimated risks in Cobb County real estate, especially on wooded lots, older subdivisions and properties that have accumulated fences, sheds, additions, pools and landscaping over several owners.

My view is simple: visible possession is not the same as legal ownership. If a sale depends on where the land begins and ends, guessing from the fence is not due diligence.

The fence is evidence—not proof

Homeowners naturally treat a fence as the property line. Sometimes it follows the boundary precisely. Sometimes it was intentionally installed several inches inside the owner’s land. Sometimes it follows convenience, terrain or an older owner’s assumption.

Only a Georgia-registered land surveyor can professionally locate property boundaries.

That distinction matters when someone says, “The tax map shows the fence is fine,” or points to a phone app displaying a parcel outline over aerial photography.

Cobb County’s online property search is useful for identifying parcels and tax information. It is not a substitute for a field survey that identifies monuments, improvements, easements and encroachments on the ground.

A recorded plat and a new survey answer different questions

Georgia’s statewide Plat Index provides access to recorded plats and maps filed through county records. Those documents can show subdivision lots, dimensions, streets and recorded easements. GSCCCA

But a recorded plat may predate the fence, pool, driveway extension or detached building now occupying the property.

A current boundary survey compares the record evidence with conditions found on the land. Depending on the scope, it may show:

• Boundary lines and corner monuments
• Fences, walls and driveways near or across a line
• Recorded utility or drainage easements
• Buildings, pools and accessory structures
• Setback or building-line concerns
• Gaps, overlaps or inconsistencies requiring further review

The old plat explains how the parcel was created or previously surveyed. The current survey explains how today’s improvements relate to it.

The expensive problem may belong to either property

An encroachment can run in two directions.

Your fence, shed, patio or driveway may extend onto the neighbor’s land. Or the neighbor’s improvement may occupy part of the property you are selling or buying.

Neither situation should be diagnosed casually. The remedy may involve removing or relocating an improvement, correcting a deed or plat, obtaining an easement, negotiating a boundary-line agreement, or securing another legal solution.

The correct approach depends on the facts and should involve the closing attorney, surveyor and other qualified professionals.

The dangerous response is, “It has been there forever, so it must be fine.” Time can make boundary matters more legally complicated—not less.

Easements create a second layer of risk

An improvement can sit entirely inside the property boundary and still create trouble because it occupies an easement, setback or public right-of-way.

Cobb County identifies blocked drainage easements and certain fence or wall conditions among common code-enforcement concerns. Its residential permitting materials separately address pools, accessory structures, additions and retaining walls. Cobb County Georgia

An easement does not automatically mean the land is unusable. It means someone else may hold defined rights across that portion of the property—for drainage, utilities, access or another recorded purpose.

That can affect where an owner places:

• Fences and gates
• Pools and pool decking
• Sheds and detached garages
• Retaining walls
• Patios, outdoor kitchens and permanent landscaping
• Driveway expansions
• Additions or accessory living structures

A contractor’s willingness to build something does not establish that the location is legally acceptable.

Why the problem often appears late

Many Georgia residential transactions proceed without a buyer ordering a new survey unless the lender, title insurer or circumstances require one. That can allow boundary assumptions to survive multiple sales.

The issue may finally surface when a buyer orders a survey, a lender asks a question, the title insurer reviews an exception, a neighbor raises a concern or a permit application reveals the conflict.

That timing is painful because leverage has changed. The seller may already have moved. The buyer’s rate lock may be expiring. Contractors and movers may be scheduled. Everyone wants a rapid answer to a problem that may require careful legal and surveying work.

Title work and survey work also serve different purposes. A title search examines recorded interests affecting ownership. A survey can reveal physical conditions—such as a fence or driveway crossing a line—that may not be evident from the public record alone.

Title coverage depends on the specific policy, endorsements, exceptions and facts. Buyers should review those issues with the closing attorney rather than assuming every boundary problem is insured.

Sellers should investigate before the sign goes up

A pre-listing boundary review is especially sensible when:

• The property has an older or irregular fence
• A pool, shed, wall or addition sits near a lot line
• The driveway is shared or curves near neighboring land
• The lot borders a creek, drainage area or utility corridor
• Markers are missing or neighbors disagree about maintenance
• The owner made significant exterior improvements without a recent survey
• Prior documents contain different dimensions or unclear references

Start by gathering the deed, recorded plat, prior survey, permits, HOA approvals and any written agreements with neighbors. If the physical layout raises a real question, consider ordering a current survey before marketing the property.

Finding an issue early does not guarantee an easy solution. It does allow the seller to address it without a closing deadline controlling the conversation.

Buyers should survey the future—not just the present

A buyer may care less about the existing fence than about the pool, addition, detached garage or outdoor-living project planned after closing.

That future use should be investigated during due diligence. Confirm the governing jurisdiction, zoning, setbacks, easements, HOA restrictions and permitting requirements. A large backyard can feel spacious while offering far less buildable area than expected.

For properties inside one of Cobb County’s municipalities, city rules and permitting authorities may apply instead of unincorporated county procedures. Verify the exact parcel rather than relying on the mailing address.

Keep the evaluation focused on objective property facts—boundaries, condition, costs, services and legal uses. Those standards support better decisions and Fair Housing compliance.

The bottom line

The fence may describe how the yard has been used. It does not conclusively describe what the owner legally owns.

A current survey can expose an uncomfortable fact, but discovering that fact before closing is far less expensive than discovering it after a dispute, permit denial or failed resale.

If you are preparing to buy or sell a Cobb County property with fences, pools, sheds, retaining walls or other improvements near the edge of the lot, Jules Harper and The Four Walls Group can help you organize the right questions and coordinate with qualified survey, title and legal professionals early.

The most expensive property line is often the one everyone assumed was somewhere else.
