Do You Need a Permit for Concrete Work in Marietta GA?
Most Marietta homeowners are surprised to learn that a concrete driveway, patio, or retaining wall requires a building permit — and that skipping the permit can create real problems at resale and during insurance claims. Georgia law and Marietta’s local ordinances treat concrete flatwork as construction that affects site drainage, setbacks, and impervious surface coverage, all of which require review before work begins. In this post, we cover which concrete projects need permits in Marietta, how the permitting process works for both city-limit and unincorporated Cobb County properties, what fees to expect, and what happens during inspections.

Why Permits Matter for Concrete Work in Marietta
Concrete permits in Marietta serve three functions: they verify that the proposed work meets local setback and drainage requirements before construction, they create an inspection checkpoint to confirm work meets building code, and they create a legal record of permitted construction that affects the property’s title and insurance coverage.
Unpermitted concrete work in Marietta can create problems at resale — a buyer’s inspector may flag unpermitted flatwork, and the seller may need to retroactively permit or remove the structure to close the sale. It can also affect homeowner’s insurance claims if damage involves an unpermitted structure. In Cobb County, where home values are high and buyer due diligence is thorough, unpermitted work is a genuine risk that costs more to resolve later than the permit costs upfront. The City of Marietta Building Permits Division and Cobb County Community Development both actively review permits as part of the inspection process for residential and commercial construction projects.
Which Concrete Projects Require Permits in Marietta GA
Concrete driveways: Always require a permit in Marietta. Both City of Marietta properties and unincorporated Cobb County properties require a permit for new driveways and driveway replacements. The permit review confirms that the driveway does not create drainage problems for adjacent properties or exceed impervious surface limitations for the lot.
Concrete patios: Require permits in Marietta. The City of Marietta’s ordinance covers patios as structures attached to or associated with the dwelling. Permit review includes setback verification (patios must maintain required distances from property lines and easements) and drainage review.
Concrete retaining walls: Any retaining wall over 30 inches in height requires a permit in Marietta. Shorter walls may or may not require permits depending on specific location and load conditions — check with the relevant permitting authority before assuming a short wall is exempt.
Concrete walkways and sidewalks: Private sidewalks connecting the driveway to the home generally require permits. Public sidewalk work along street frontage involves the City of Marietta Public Works Department in addition to standard building permits.
Concrete slabs (for sheds, accessory structures): Any concrete slab supporting an accessory structure (shed, workshop, garage) requires a permit as part of the accessory structure permit — not separately as a slab permit.
Concrete repair and resurfacing: Surface repairs — crack filling, patching, and resurfacing overlays — typically do not require permits in Marietta or Cobb County. Structural repairs that involve breaking out and replacing full slab sections may require a permit based on scope.
How to Apply for a Concrete Permit in Marietta GA
Properties within Marietta city limits: Applications go through the City of Marietta Building Permits Division. The city requires a site plan showing the proposed concrete work in relation to property lines, setbacks, and existing structures. Applications can be submitted in person at City Hall or through the city’s online permitting portal. Contact the Building Permits Division at the City of Marietta municipal website for current submission requirements.
Properties in unincorporated Cobb County (outside city limits): Applications go through Cobb County Community Development. Cobb County has an online permit portal and accepts in-person applications at the Community Development office. Unincorporated Cobb County properties must verify which jurisdiction applies — not all Marietta addresses are within the city limits, and the boundary matters for both permitting and inspections.
Typical residential concrete permit fees in Marietta run $50–$200 for flatwork projects. Commercial concrete projects are priced on a sliding scale based on project value and may require additional site plan review fees.
What Happens During Concrete Inspections in Marietta
Permitted concrete projects in Marietta typically require two inspections:
Pre-pour inspection (footing/sub-base inspection): The inspector visits after the forms are set and reinforcement is placed, but before the concrete is poured. This confirms that the sub-base is prepared correctly, forms are at the right elevation, reinforcement meets the permit specifications, and the drainage slope is correct. If the inspector finds deficiencies, the work is corrected before pour authorization is given.
Final inspection: After the concrete has cured, the inspector confirms the finished work matches the approved permit drawings, drainage is functioning correctly, and any required setbacks are maintained. The final inspection sign-off closes the permit and creates the permanent record of the permitted construction.
Marietta Concrete Works schedules all permit applications and inspections on behalf of our clients — homeowners don’t need to manage the process directly.
Frequently Asked Questions About Concrete Permits in Marietta
How long does it take to get a concrete permit in Marietta GA?
Residential permit approvals in Marietta typically take 5–10 business days for straightforward flatwork projects. Complex projects requiring additional drainage review or variance applications take longer. The City of Marietta’s online portal provides real-time permit status tracking. We factor permit lead time into project scheduling so there are no delays once the permit is approved.
What happens if I do concrete work without a permit in Marietta?
Unpermitted concrete work in Marietta can result in a stop-work order from the City or Cobb County, requiring work to halt until a permit is obtained. In some cases, existing work may need to be removed and redone after permit approval if it doesn’t meet code requirements. At resale, unpermitted work must typically be disclosed or retroactively permitted, which can delay closing or reduce the sale price. The permit cost ($50–$200 for residential flatwork) is a small investment to avoid these outcomes.
Do HOAs require additional approval for concrete work in Marietta?
Many Marietta neighborhoods — particularly in East Cobb communities like Chimney Springs and Windsor Oaks — have HOA architectural review processes for exterior changes including driveways and patios. HOA approval is required in addition to the City or County permit; neither process substitutes for the other. We provide material specifications, layout drawings, and color samples to support HOA Architectural Review Board submissions for clients in governed communities.
