Concrete Permit Lawrenceville GA: What Requires One?
Before you hire a concrete contractor in Lawrenceville, you need to know whether your project requires a Gwinnett County permit — because starting work without the right permit can result in stop-work orders, mandatory demolition of completed concrete, and fines. The rules are specific, and they depend on exactly what you’re building and where on your property it sits. This guide explains the current Gwinnett County permit requirements for common concrete projects in Lawrenceville, based on the county’s Zoning, Inspections, and Permitting (ZIP) Portal requirements.

The Basic Rule: What Triggers a Permit in Gwinnett County
The most commonly asked question in Lawrenceville concrete projects is whether a driveway or patio requires a permit. The answer depends on what percentage of the front yard the hardscaped area will cover.
Gwinnett County’s standard rule: Driveways, sidewalks, and basketball slabs in front yards do not require a permit when the total impervious coverage remains at or below 35% of the front yard area. When coverage exceeds 35%, a permit is required through the Gwinnett County Zoning, Inspections, and Permitting (ZIP) Portal before work begins.
Most single-car driveways in Lawrenceville fall under the 35% threshold. Wider driveways, circular drives, and driveways with adjacent concrete aprons may approach or exceed the threshold. If you’re unsure whether your project meets the limit, measure your front yard’s total area and calculate what percentage the proposed concrete will cover.
Project-by-Project Permit Guide for Lawrenceville
Concrete Driveways
Standard single or two-car driveway (front yard, under 35% coverage): No permit required. This covers the majority of straightforward driveway replacements in Lawrenceville neighborhoods.
Widened driveway or additional apron that pushes coverage above 35%: Permit required through the Gwinnett County ZIP Portal before work begins.
Driveway with a new curb cut on a county or city road: A separate encroachment permit may be required from Gwinnett County’s Department of Transportation if your project adds or modifies the point where your driveway meets the public road. This is separate from the building permit.
Commercial driveways or multi-family residential: Always require permits and pre-construction plan review. Contact Gwinnett County’s Development and Inspections division directly for commercial project requirements.
Concrete Patios and Slabs
Backyard patio slab (not attached to house): Generally does not require a permit in Gwinnett County if it’s a standalone slab. However, if the slab connects to covered structures, pergolas, or screen enclosures, the attached structure likely requires a permit.
Patio attached to the house structure or sharing a ledger with the house framing: Requires a building permit and inspection. The concrete work becomes part of the permitted structure.
Pool decks and surround slabs: Pool construction itself requires permits, and the concrete deck is typically included in the pool permit scope. If you’re adding or modifying a pool deck on an existing permitted pool, consult Gwinnett County about whether a separate permit is needed.
Concrete Walkways and Sidewalks
Private walkway within your property (front or back): No permit typically required under the standard impervious coverage rules if total front yard coverage stays under 35%.
Public sidewalk adjacent to your property: Any concrete work in the public right-of-way — including adjacent sidewalk panels, ADA ramp transitions, and curb cuts — requires Gwinnett County coordination and may require a right-of-way encroachment permit, regardless of project size.
Concrete Foundations
New foundation slab for a home addition, detached garage, or accessory dwelling unit: Always requires a building permit, structural engineering review (in many cases), and multiple inspections — including a pre-pour inspection where the Gwinnett County inspector reviews the formwork, rebar placement, and base preparation before any concrete is poured.
Foundation repair (crack injection, underpinning, mudjacking): Typically does not require a permit when it’s maintenance or repair of an existing foundation, but structural modifications to a foundation may require permits and engineering approval.
Outbuilding or workshop foundation: Requires a building permit if the structure itself requires a permit (which it typically does above 144 sq ft in Gwinnett County). The concrete foundation permit is usually pulled as part of the structure permit.

How to Apply for a Permit Through Gwinnett County’s ZIP Portal
Gwinnett County’s online permit system — the Zoning, Inspections, and Permitting (ZIP) Portal — allows homeowners and contractors to submit permit applications, upload required documentation, and track permit status without in-person visits to the Development and Inspections office.
What you’ll typically need for a concrete driveway permit application:
- Site plan showing property lines, existing structures, and proposed concrete area
- Calculation of total impervious surface coverage (square footage of proposed concrete as a percentage of front yard)
- Contractor’s license information (if a contractor is pulling the permit on your behalf)
What you’ll need for a foundation permit:
- Architectural or structural drawings of the proposed addition or structure
- Foundation design and rebar specification (engineered drawings typically required for attached additions)
- Survey or site plan showing the proposed structure’s location relative to property lines and setbacks
Timeline: Straightforward residential permits in Gwinnett County are typically approved within 5–10 business days through the ZIP Portal. More complex projects that require plan review take longer.
What Happens If You Skip the Permit?
Gwinnett County inspectors conduct routine compliance checks on residential construction activity. Unpermitted concrete work discovered during an inspection — or flagged by a neighbor complaint — can result in a stop-work order requiring all activity to halt immediately.
If work has already been completed without a permit that was required, you may be required to obtain a retroactive permit. Retroactive permits often require exposing the foundation or base to verify construction compliance — which can mean demolishing the concrete to allow inspection. This outcome is significantly more expensive than pulling the permit before work starts.
When you sell your home, title companies and home inspectors often flag unpermitted additions or structures. An unpermitted concrete addition — particularly a foundation or attached structure — can complicate or delay a home sale.
Why Your Contractor Should Know This
A concrete contractor working regularly in Lawrenceville and Gwinnett County should know the permit requirements for standard residential concrete projects without needing to look them up. When you’re evaluating contractor proposals, asking “does this project require a Gwinnett County permit?” and listening to the quality of the answer is a reliable test of local market experience.

Frequently Asked Questions
Do I need a permit to replace my concrete driveway in Lawrenceville GA?
Usually not, as long as your front yard impervious coverage stays at or below 35% after the replacement. Most standard single-car or two-car driveway replacements in Lawrenceville fall under this threshold. Wider driveways, circular drives, or additions that significantly increase front yard coverage may require a permit through Gwinnett County’s ZIP Portal. If you’re not sure, calculate your front yard’s total square footage and measure the proposed concrete area — the math is straightforward.
How long does a Gwinnett County concrete permit take?
Straightforward residential concrete permits submitted through Gwinnett County’s ZIP Portal are typically approved within 5–10 business days. Projects requiring plan review — foundations, additions, complex structures — may take 2–4 weeks. Always apply for the permit before work begins; retroactive permits are significantly more complicated and costly.
Can my concrete contractor pull the permit in Gwinnett County?
Yes — in most cases, a licensed contractor can pull the permit on your behalf through the Gwinnett County ZIP Portal. This is often the most efficient approach because the contractor already has the required license and insurance information in the system. Make sure the permit is actually pulled and a permit number is issued before work starts — not just applied for.
