Before you choose a fence for a Cobb County property, settle three questions: which government reviews the address, where the fence can sit, and which approvals apply to the whole project. A fence quote is easier to compare when those answers accompany the drawing.
Start with the jurisdiction, not the mailing address
Cobb County’s residential permitting page provides an address-based jurisdiction tool and describes the county office’s unincorporated-area scope. A Marietta mailing address does not by itself establish that the parcel is inside the City of Marietta.
This distinction also matters in Mableton. The county’s codes and standards page says Mableton began accepting its own building and development permits on March 1, 2025. Send a new city project to the responsible city office, rather than assuming the county still handles it.
Ask staff to confirm zoning, any conditions attached to the parcel, and historic or corridor review. Keep that response with the survey. HOA approval is a separate step; do not treat either approval as a substitute for the other.
Use the county height guidance carefully
The county’s posted residential code-enforcement brochure describes a six-foot maximum for a fence or wall adjacent to a public road right-of-way and within a residential front yard, and eight feet at the rear. It includes posts and ornaments in the height. This corrects the four-foot-front/six-foot-rear figures previously published here.
The brochure is dated March 2019. Use it as the county’s published starting guidance, then have Zoning confirm the current standard for your parcel and each fence run. It is not authority to apply county limits inside every Cobb city, to ignore a corner-lot visibility restriction, or to build a pool barrier without further review.
On a slope, ask how height will be measured before agreeing to stepped or following-grade panels. Show any retaining wall, cap, or decorative topper in the elevation drawing. A nominal panel height alone does not describe the full installation.
Mark the fence and the restrictions on one plan
Start with a survey or recorded plat, then identify anything it does not settle. Draw the fence runs, gates, house, street frontage, driveway, known easements, streams, and drainage features. A curb, old fence, or mowing line should not be used to resolve an uncertain boundary.
Do not assume every lot has the same easement width or that a neighbor’s agreement authorizes construction in one. Read the recorded terms and ask the easement holder about access. If the boundary is disputed, resolve it with a surveyor and appropriate legal advice before setting posts.
Separate ordinary fencing from special project work
Use Cobb’s permitting resources to ask about the actual scope. The office provides separate information for pools, retaining walls, and accessory structures. A fence combined with one of these projects should not be treated as an ordinary fence simply because the panels are familiar.
For a pool, have the proposed enclosure and every access point reviewed together. Include gate operation, gaps, nearby climbable objects, and any door from the home. This article does not establish a countywide pool-barrier dimension.
For a wall-and-fence combination, ask who designs the attachment and confirms the wall can support it. Do not accept a generic fence-post detail as an engineered retaining-wall connection.
Agree on responsibilities before installation
Ask for the contract to identify who obtains each required approval, who supplies the boundary information, what is included in removal and disposal, and what happens if rock or an unrecorded obstruction is found. Request current fees and review schedules from the reviewing office rather than relying on an online estimate.
Before digging, follow the Georgia 811 ticket and response process and arrange identification of private lines that the public locate does not cover. Sprinkler tubing and power to an outbuilding need attention too.
If you receive a violation notice, use its actual instructions and deadline. Do not rely on a generalized fine range, guaranteed appeal period, or promise that a contractor can secure a variance.
Questions to take to Zoning
Ask: Is this parcel under county or city review? What is the yard classification for each run? What height and material limits apply? Is a permit or other approval needed? Are the proposed gate, drainage crossing, or wall attachment separate review items? Get unclear answers resolved on the plan before ordering materials.
Work through these common planning situations
A side yard faces a second street. Show both street edges on the drawing and ask how the lot’s yards are classified. Do not label the street-facing side as a rear yard simply because it is beside the house. Include the driveway and any proposed gate so the reviewer can assess the complete location.
The fence will sit above a retaining wall. Show the wall, the ground levels on both sides, and the proposed fence mounting. Ask how height is measured in that configuration and whether the wall or mounting needs separate review. A fence height that works on level ground may not answer the combined wall-and-fence question.
You are replacing a fence in the same place. Bring photos and dimensions of the old fence, but ask whether the replacement design is allowed under the current rules. Existing placement does not establish a verified boundary or automatic approval for a taller or different-material replacement.
You want to move forward while a question is pending. Gather product samples and compare preliminary scopes, but mark the unresolved layout item on every request. Avoid ordering nonreturnable custom gates or fixing the final post locations until the responsible office has answered the material question.
Keep one project record
Save the survey or other accepted site document, written zoning response, approved drawing, HOA response if applicable, and final quote together. Give the crew the current version of the layout. If a gate or fence run changes, update the drawing and check whether the change needs further review.
