Marietta Water Line Permits: What's Required
When a permit is required for water-line work in Marietta, who applies for it, and how to check whether City of Marietta or Cobb County rules apply.
Permits Are Required for Water Line Work in Marietta
The City of Marietta requires a plumbing permit for any work on a plumbing system, and this explicitly includes water supply lines, not just sewer work or new construction. That means a repair or replacement on the service line running from your meter to your house is permit work.

Who Actually Applies for the Permit
In Marietta, homeowners generally cannot apply for a plumbing permit themselves. The professional performing the work, specifically the license holder, applies for the permit on the property owner's behalf. That's worth knowing if you're comparing quotes: whoever does the work needs to be positioned to pull the permit correctly.
Cobb County Is a Separate Process
If your property sits in unincorporated Cobb County rather than inside City of Marietta's actual jurisdiction, a different permitting process applies. Cobb County publishes its own residential permitting resources and water-line inspection codes, and separately distinguishes standard utility permitting from right-of-way permitting.
Because a Marietta mailing address doesn't guarantee City of Marietta jurisdiction, confirm which set of rules actually applies before permitting or work begins. See who's responsible for the water line from meter to house for how to check.
What the Inspection Actually Confirms
A permit isn't just paperwork filed before work starts; it comes with an inspection tied to it. For water-line work, that means the trench or access point stays open until the inspection happens, rather than being backfilled the moment the new pipe is in the ground.
Why Skipping the Permit Is a Real Risk
Unpermitted plumbing work is the kind of thing that surfaces during a home sale, an appraisal, or an insurance claim, at exactly the point where it's hardest to deal with. If a problem develops on a line that was never inspected, undoing that means digging the work back up to bring it into compliance after the fact.
Handled by the Professional Doing the Work
Pulling the permit up front is part of the job for the licensed professional performing the work, not a separate task added to your own to-do list.

Common questions about permit requirements for water-line work.
Do I need a permit to repair my water line in Marietta?
The City of Marietta requires a plumbing permit for work on a plumbing system, which includes water supply lines. This applies to repair and replacement work on the service line, not just new construction.
Can I pull the permit myself as a homeowner?
Generally no. In Marietta, the license holder performing the work applies for the plumbing permit on the property's behalf, rather than the homeowner applying directly.
What if my property is in unincorporated Cobb County instead of the City of Marietta?
Cobb County has its own residential permitting process and water-line inspection codes, separate from the City of Marietta's, and separately distinguishes ordinary utility permitting from right-of-way permitting.
What happens if water line work is done without a permit?
Unpermitted work never gets the inspection that's supposed to confirm it meets code, which becomes a real problem later — at resale, during a home inspection, or with an insurance claim.
Does the permit process add much time to a repair or replacement?
It adds a step, but a licensed professional who does this work regularly already has the process down. Exact timing depends on the jurisdiction's current review and inspection scheduling.
Do trenchless water line replacement and directional boring also require a permit?
Yes. Installing a new water line, whether by open trench, trenchless replacement, or directional boring, requires a plumbing permit in the City of Marietta, applied for by a licensed professional.
