    3GM Signs and Graphics, Your Local

    Sign Company in Marietta, Georgia

    Everybody wants a sign company that gets it right the first time: good materials, the correct permit, and an install that happens on schedule. The wrong choice often means a sign that fades early or a permit problem that delays your project. 3GM Signs has been creating and installing signs in Marietta since 1985, for businesses, schools, churches, HOAs, and families, from our shop at 4011 Canton Rd, about 15 minutes north of the Marietta Square.

    We are a family-owned shop, offering a full range of signs and graphics including storefront and building signs, monument signs for offices and neighborhoods, vehicle wraps and lettering, banners, window graphics, and interior signs. Whether you need one sign or a full set, we help you choose the right solutions for your signage needs.

    Because we are local, it makes the sign buying process simple. You can see material samples or pickup finished signs at our shop, we can measure on site, and we offer professional installation throughout Marietta and greater metro Atlanta. We also know how Marietta permitting works: signs near the Marietta Square need approval from the Historic Board of Review, most city permits go through the SagesGov portal, and some Marietta addresses are actually in unincorporated Cobb County, where the county's rules apply.

    What to know before you order a sign in Marietta, GA

    The first thing to settle on any Marietta sign is which permit rules apply to your address. Signs near the Marietta Square go before the Historic Board of Review, which expects conservative colors and may require specific materials. Many Marietta addresses are actually in unincorporated Cobb County, which has its own process. We confirm which one applies before we start, so the permit never becomes a surprise.

    The Marietta Square and the historic district

    Signs near the Marietta Square fall in the Downtown Marietta Sign District, so the Historic Board of Review has to approve the design before the city issues a permit. The district expects conservative colors, quality materials, and usually one sign per building frontage. We design to those rules so the approval goes smoothly.

    Landlord and shopping-center rules

    Many Marietta businesses lease space in shopping centers or office buildings that set their own sign criteria on top of the city's. We help you line up those approvals early so nothing stalls at the last minute.

    City limits vs. unincorporated Cobb

    A Marietta address can sit inside the city or in unincorporated Cobb County, and the two have different sign rules and different permit offices. We confirm which one applies before we build.

    The Stakes

    AVOID THE RISKS

    Of choosing the wrong provider in Marietta, GA

    Marietta has no shortage of sign companies, but they are not all the same. Choosing the wrong sign provider in Marietta, GA can create lost trust, lost money, lost opportunity, and frustration.

    Lost Trust

    A faded banner or a crooked, cheap-looking sign tells Marietta customers something about your standards before they ever walk in, and it is rarely what you meant to say.

    Lost Money

    Hire someone who skips the City of Marietta or Cobb County details and you can pay twice: once for the sign, then again for the rework, the re-permit, or the takedown when it does not pass.

    Lost Opportunity

    A dull, hard-to-read sign quietly costs you customers. People who would have stopped in drive past instead, and you never know it happened.

    Frustration

    The wrong shop leaves you chasing proofs, permit answers, and install dates while you are trying to run a business. The right one simply handles it.

    Eian Wilson

    I highly recommend this sign company. They did an incredible job for us--we have a large sign out on the road by our business as well as a sign on the building of the business. After working with the designer, the result is fantastic. The signs are exactly what we wanted and the price was competitive. The job was completed in a timely fashion. We're sold! 3GM Signs is our go-to sign company from now on!

    Permits and local approvals

    Do You Need a Sign Permit in Marietta, GA?

    In Marietta, many signs need a permit before they go up, and the first question is always the same: where exactly is the property? A Marietta mailing address can sit inside the city or in unincorporated Cobb County, and that line, not the address on the envelope, decides who reviews your sign.

    It matters because the city and the county set their own rules for size, height, placement, mounting, and illumination. Inside city limits, Marietta reviews permanent signs under Division 714, usually through its SagesGov portal. Outside, Cobb County's sign ordinance and permit path apply instead.

    Under the City of Marietta's sign ordinance (Division 714), many signs need a permit before installation, and most permits are filed online through the city's SagesGov portal. Signs in the Downtown Marietta Sign District around the Marietta Square carry an extra step: the Marietta Historic Board of Review must approve the design before the permit is issued. Addresses outside city limits fall under Cobb County's permit path and sign ordinance instead.

    Start by confirming whether your address is inside Marietta city limits or in unincorporated Cobb County, because that single fact sets the whole permit path. We are glad to verify it for you and steer the project through the right office, including the Historic Board of Review if you are near the Marietta Square.

    A quick shortcut for businesses: check who issues your business license. In Georgia, the local business license — the occupational tax certificate — comes from the City of Marietta when your location is inside city limits, and from Cobb County when it is unincorporated. Because sign permits follow that same city-limits line, whoever issued your license is very likely the office that reviews your sign.

    Which signs usually need a permit

    In Marietta, permits often apply to permanent exterior signs, and downtown adds a design-review step. Check these before production:

    • Wall, storefront, and channel-letter signs
    • Freestanding and monument signs
    • Illuminated and electrified signs
    • Tenant-panel and face changes
    • Sidewalk A-frame signs downtown

    How the permit process works

    Once you know a Marietta sign needs a permit, the path usually runs like this:

    • Confirm whether the property is inside Marietta city limits or unincorporated Cobb County.
    • For downtown addresses, secure Historic Board of Review approval before filing.
    • File the sign permit and drawings through the city's SagesGov portal, or the Cobb County path if outside the city.
    • Wait for the issued permit before installing the sign.

    How 3GM keeps your permit on track

    We have prepared permit-ready details for Marietta and Cobb County projects since 1985, so the requirements never land on your desk. Here is how we keep things moving:

    • We confirm up front whether your address is City of Marietta or unincorporated Cobb County, so the permit starts on the right track.
    • We prepare the drawings reviewers expect, including dimensions, materials, placement, mounting method, colors, and illumination, and file through SagesGov when the city is the authority.
    • For downtown projects, we design to Historic Board of Review expectations and help assemble the approval package before the permit goes in.
    • We gather landlord, shopping-center, and HOA criteria early so a private rule does not surprise the project after production.

    What to confirm before we build your Marietta, GA sign

    • Confirm whether the address is inside Marietta city limits or in unincorporated Cobb County, because the two use different sign rules through different offices.
    • If the sign is in the Downtown Marietta Sign District, plan for Historic Board of Review approval, conservative colors, and generally one sign per building frontage.
    • Sidewalk A-frame signs downtown need their own annual permit, proof of liability insurance naming the City, and a clear pedestrian path.
    • Landlord, shopping-center, and HOA criteria can be stricter than the city's, so we gather those up front too.

    Permit requirements can change. Always verify the current city or county rules for the exact project address before installation.

    FAQ

    Questions about signs in Marietta, GA

    We are at 4011 Canton Rd, Marietta, GA 30066, on Canton Road between Kennesaw and the Square. It is an easy stop for proofs, material samples, and pickup.

    It depends on the type of sign. Storefront, wall, projecting, window, illuminated, temporary banner, and sidewalk A-frame signs near the Square commonly need a city permit, and the Historic Board of Review may need to approve the design first. Interior-only signs, normal vehicle graphics, and other limited-use graphics can follow different rules, so we confirm the sign type and exact location before production.

    There can be. The Downtown Marietta Development Authority offers a 50/50 matching grant of up to $3,000 for businesses in its district to improve storefront signs and awnings. Programs and amounts change, so confirm current details with the City of Marietta's economic development office at mariettaga.gov. We are glad to design a sign that fits the program.

    It is worth checking, because the city and the county have different sign rules and different permit offices. Inside the city, signs go through Marietta's process and the SagesGov portal; outside, Cobb County's rules apply. We confirm which one covers your address before we build.

    Yes. We handle single-vehicle lettering, partial and full wraps, and repeatable fleet graphics, so trucks you add later still match. Many Marietta service companies have us cycle vehicles through as they grow.
