Gwinnett County building permits come from the Department of Planning and Development, which issues them for construction in the unincorporated areas of the county. Gwinnett has 17 municipalities, and each permits its own work — so the first question on any Gwinnett job is not what you are building but who is entitled to permit it.
The county's answer to that question has one deliberate exception. Planning and Development also issues permits for all county-owned projects and all Gwinnett County Board of Education projects regardless of location — so a school project inside a city's limits is still a county permit. The boundary settles most cases and not all of them.
Applies to unincorporated Gwinnett County, plus county-owned and Board of Education projects anywhere in the county. Work inside Lawrenceville, Duluth, Suwanee, Snellville, Buford, Norcross, Sugar Hill, Lilburn, or any other Gwinnett city is permitted by that city — including Mulberry, the newest, which has issued its own permits through SagesGov since January 1, 2025.
Register your trades before you need them. Subcontractors performing work that requires a building permit must register with the department first — and re-register whenever the state contractor licence renews or any business detail changes. A current state licence sitting behind a stale county registration is the version of this that surprises people on mobilisation day.
What requires a permit in Gwinnett County?
A Gwinnett County building permit is required before most construction, alteration, repair, demolition, or change of occupancy — but only where the county is the permitting authority. The Department of Planning and Development issues building permits for construction located in the unincorporated areas of Gwinnett County. Gwinnett contains 17 municipalities, and a project inside any of them files with that city rather than with the county.
There is one deliberate exception worth knowing, because it runs the other way: the department also issues building permits for all county-owned projects and all Gwinnett County Board of Education projects regardless of where they sit. A school addition inside a city's limits is still a county permit. That is unusual, and it catches contractors who assume the city boundary settles the question in every case.
Two things did not move with the rest. The energy code is still the 2015 International Energy Conservation Code with Georgia supplements and amendments, so an envelope or mechanical package built to a newer IECC is being checked against an older one. And the International Existing Building Code (2018) is permissive, not mandatory — it governs your renovation only if that particular city or county adopted it. Two jurisdictions an hour apart can treat the same existing-building alteration under different rulebooks, and neither is doing anything wrong.

Gwinnett County building department: who handles permitting
Permitting sits in the Department of Planning and Development, which runs Planning, Infrastructure Planning, Development, Building, Customer Experience, Code Enforcement, Administration, Economic Development, and Housing and Community Development as divisions of one department. Building permits, plan review and subcontractor registration sit together under the department's Building Services, which reviews plans, issues permits and performs inspections for residential and commercial construction. Questions are routed by project type: single-family house and townhome permitting has its own building permits contact, while commercial and multifamily permitting goes through the department's Customer Support Center.

Get a free quote →That split matters when you are chasing a file. Commercial buildings, commercial structures, and commercial interior projects — where commercial means everything other than one- and two-family dwellings and townhomes — are applied for through the ZIP Portal's commercial permit application rather than the residential one, and the county lists separate Building Permits and Building Plan Review phone lines. Residential work does not route through commercial plan review, so calling the plan review line about a house permit sends you to the wrong desk.
Building Services works out of One Justice Square in Lawrenceville. Counter hours run 8:00am to 5:00pm Monday through Friday except holidays, but payments are only accepted until 4:00pm — an hour before the doors close. A file that is otherwise ready but arrives at 4:30pm does not get paid for that day, and in Gwinnett the permit does not issue until the fees clear.

Applications for construction permits and inspection requests both run through the county's ZIP Portal. Once plan review is complete, fees are paid, and contractor information has been provided, the construction permit is issued to the contractor of record — so the contractor field is not a formality, and it is the name that ends up on the public permit.
The department has publicly warned about fraudulent emails claiming to come from Gwinnett Planning and Development or the Planning Commission and asking for wire transfers or payment details. The department's guidance is to send nothing, click nothing, and call 678-518-6000 to report it. Permit payment fraud has now been documented across multiple jurisdictions in several states; treat any emailed change of payment instructions as false until you have confirmed it by phone.
In 2025, building permits issued in unincorporated Gwinnett County authorized 2,403 new privately owned housing units, 2,259 of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.
Gwinnett County permits: record types and what each covers
Gwinnett's records are organised around the split between residential and commercial review, with land disturbance running on its own track. Permit case numbers carry the record type on the front — a residential building permit reads like RESBLD2022-00001 — and you need that number to schedule an inspection. These are the records you will actually file:

Solar permits in Gwinnett County
In Gwinnett a residential array is filed through the ZIP Portal like any other permit, and the installing electrical contractor needs to hold a current county subcontractor registration as well as its state Chapter 14 licence. Confirm the parcel is unincorporated before filing: several of the county's cities run their own solar review, and a rooftop array is exactly the size of job where the address gets assumed rather than checked.

Reroofs in unincorporated Gwinnett are county permits; the same job three streets away inside a city is not. Because the permit issues to the contractor of record and that name reaches the public permit record, a roofing company filing under a registration that lapsed when its state licence renewed will find the problem at issuance rather than at inspection.
Solar and roofing work are built to the statewide codes, permit rules are set locally, and utilities run interconnection on their own timeline. Georgia rules
Gwinnett County permit cost
Gwinnett publishes separate fee schedules for residential work and for commercial and multifamily work, both as documents rather than as a calculator, and the department maintains a general fee schedule alongside them. Building permit fees are valuation-driven, with trade permits charged as their own records and plan review carried inside the permitting process for commercial files.
Two practical points shape what you actually pay. Underestimating project value to reduce the fee is checked during review and corrected, so a low valuation buys a revision rather than a saving. And because payment closes at 4:00pm while the counter stays open until 5:00pm, a fee approved late in the day lands on the next business day — which matters when a permit is gating a crew.
Land disturbance is priced and reviewed separately from the building permit. Under the 2026 amendments to the erosion and sedimentation statutes the land-disturbance track now carries its own consequences for missed deadlines, including a refund of application fees, so the two permits are worth tracking as distinct financial items rather than as one line.
| Fee component | How it works |
|---|---|
| Residential building permit | Valuation-based, per the published residential fee schedule |
| Commercial and multifamily | Valuation-based, per a separate published schedule |
| Trade permits (E/P/M) | Charged as their own records against the building permit |
| Land disturbance | Priced separately on the erosion and sedimentation track |
| Valuation review | Understated project value is corrected during review |
| Payment window | Accepted until 4:00pm, Monday to Friday |

Gwinnett County trade permits
Gwinnett adds a registration step, and it stops jobs. Trade subcontractors performing construction for which a building permit is required must first register with the Department of Planning and Development. Registration is not a one-time event: a Subcontractor Registration form is required if the trade has not previously registered, whenever the state contractor licence renews, and on any change to the registration — business name, business address, contact information, or the type of state contractor licence held.
Registration first
A trade that has never worked in unincorporated Gwinnett registers before it can be permitted. Build the lead time into the schedule rather than discovering it the morning the crew arrives.
Then the affidavit
After registering and before construction, the trade submits a Subcontractor Affidavit identifying the building permits it intends to work under — required whenever the subcontractor information was not supplied when the permit was issued.
Renewal is a trigger
Registration has to be refreshed when the state licence renews. A lapsed registration behind a current licence is the common failure, because the licence looks fine.
State licence still governs
Registration is a county record, not a licence. The Chapter 14 trade licence is what authorises the work, and it is required regardless of the value of the job.
Georgia licenses residential contractors through a state board once a job passes $2,500, licenses commercial general contractors at any job value, and licenses electrical, plumbing and conditioned air contractors separately at any job value. Georgia rules

Want this handled start to finish?
Get a free quote →17 municipalities permit their own construction. Use the department's guide for determining whether a building or lot is in unincorporated Gwinnett County, and do it from the parcel rather than the mailing address. The exception runs the other way for county-owned and Board of Education projects, which are county permits wherever they sit.
Any trade subcontractor working under the permit must already be registered with the department, with registration refreshed if the state licence has renewed or any detail has changed. Decide who the contractor of record will be before you file, because the permit issues to that name and it is the name the public record carries.
Commercial buildings, commercial structures, and commercial interior projects are filed as commercial permits and go through commercial plan review; one- and two-family dwellings and townhomes are filed as residential permits. Draw to the 2024 Georgia State Minimum Standard Codes with the Georgia Amendments, and check whether special inspections are required — the adopted building code requires them for a range of construction, additions, and renovations of existing structural systems.
Applications for construction permits are submitted through the county's Zoning, Inspections, and Permitting portal. Upload plans at full resolution; compressed or low-resolution sets fail the plan checker and cost a cycle. If the project disturbs land, file the land-disturbance application as its own record on its own timeline.
Work the comments back through the portal. Once review is complete, fees are paid, and contractor information is in, the permit issues to the contractor of record. Payments are accepted until 4:00pm — an hour before the counter closes — so plan the last step of a rush file around that, not around 5:00pm.
Inspections are scheduled through the ZIP Portal and you need the permit case number to do it, in the department's own example format RESBLD2022-00001. Keep the permit and approved plans on site, and where a private professional provider is doing the inspecting, know that an approved report the county does not challenge in two business days is approved as a matter of law.
Inspections in Gwinnett County
Inspections are requested through the ZIP Portal against the permit case number. Without that number the system has nothing to attach the request to, which is why the confirmation email from the application step is worth keeping — it is the thread that connects the application, the permit, and every inspection that follows.
The International Building Code with Georgia Amendments in effect for the state requires special inspections during construction of buildings, structures, and additions, and during renovation of existing structural systems and components. Special inspections are arranged by the applicant through an approved agency and reported to the county; they are not the same thing as the county's own inspections and do not replace them.
For private-provider inspections, also from July 1, 2026, the local governing authority keeps two business days to identify deficiencies in an approved inspection report, and any deficiency notice must describe the problem and name the regulatory requirement that has not been met. If no timely written notice arrives, the inspection is deemed approved as a matter of law. Correcting a deficient report afterwards cannot undo or delay work the private professional provider already approved (O.C.G.A. § 8-2-26(g)(14)).
Keep the permit and the approved plans on site throughout. A Georgia building permit generally becomes invalid if work does not begin within 180 days of issuance, or if work is suspended or abandoned for 180 days after commencing, under the administrative provisions of the adopted International Building and Residential Codes — local ordinance may set a different period, and extensions are usually available in writing on request.

Frequently asked questions
Who issues building permits in Gwinnett County, GA?
The Gwinnett County Department of Planning and Development, through its Building Services, for construction located in the unincorporated areas of the county. Gwinnett's 17 municipalities permit work inside their own limits.
Does Gwinnett County permit work inside its cities?
Only in one situation. The department issues permits for all county-owned projects and all Gwinnett County Board of Education projects regardless of where they are located, so a school project inside a city is still a county permit. Ordinary private construction inside a city is permitted by that city.
How do I know whether my property is in unincorporated Gwinnett?
The department publishes a guide for determining whether a building or lot is in unincorporated Gwinnett County. Check the parcel rather than the mailing address — a postal address carrying a city name does not establish that the land is inside that city's limits.
What is the ZIP Portal?
Gwinnett's Zoning, Inspections, and Permitting portal. Construction permit applications and inspection requests are both submitted through it, and it carries a Citizen Access search that lets you look up the department's permit and case types on your own criteria.
Do subcontractors have to register with Gwinnett County?
Yes. Trade subcontractors that perform construction for which a building permit is required must first register with the Department of Planning and Development. A Subcontractor Registration form is required if the trade has not previously registered, when the state contractor licence renews, and on any change to the business name, address, contact information, or licence type.
What is a Subcontractor Affidavit?
A separate form filed after registration and before construction, identifying the specific building permits the trade intends to work under. It is required where the subcontractor information was not provided at the time the permit was issued.
When does Gwinnett County stop taking permit payments?
Payments are accepted until 4:00pm, Monday through Friday, although the office is open until 5:00pm. Because the permit issues once fees are paid, a file that clears review late in the afternoon can lose a day on that hour alone.
What code does Gwinnett County enforce?
The Georgia State Minimum Standard Codes. Georgia moved to the 2024 International Building and Residential Codes with Georgia Amendments, plus the 2024 plumbing, mechanical, fuel gas, and pool codes and the 2023 National Electrical Code with the 2026 Georgia Amendments, effective January 1, 2026. The energy code remains the 2015 IECC with Georgia supplements.
Are special inspections required in Gwinnett County?
The building code with Georgia Amendments in effect for the state requires special inspections during construction of buildings, structures, and additions, and during renovation of existing structural systems and components. They are arranged by the applicant through an approved agency and are additional to the county's own inspections.
Can a homeowner pull their own permit in Gwinnett County?
Yes, on their own property, with proof of ownership and a signed Property Owner as Contractor affidavit. That places the homeowner in the contractor position for the permit, with the responsibilities that carries.
When is a Georgia contractor licence required?
For residential work, once the total value of the work, or the contractor's compensation if higher, exceeds $2,500; commercial general contractors need a licence at any value. An unlicensed contractor's contract for licensable work is unenforceable by that contractor, and it cannot file a lien or make a bond claim. Trade licences under Title 43, Chapter 14 are required regardless of job value.
How do I schedule a Gwinnett County inspection?
Through the ZIP Portal, using the permit case number — the department's own example format is RESBLD2022-00001. Keep the permit and the approved plans on site for the inspector.
