    3GM Signs and Graphics, Your Local

    Sign Company Near East Cobb, GA

    Your subdivision entrance sign, church campus sign, or office building sign is the first thing visitors see when they pull in. A sign that is well built and fits the setting tells people the property is cared for. One that is fading, generic, or out of code tells them the opposite. 3GM Signs has been building and installing signs across East Cobb since 1985, from our shop on Canton Rd in Marietta, about ten to twenty minutes from most East Cobb addresses.

    East Cobb properties keep us busy with carved and sandblasted entrance monuments for subdivisions and HOAs, campus and wayfinding signs for schools and churches, building and office signs, banners, window and interior graphics, and vehicle wraps and fleet lettering for local service companies. If you need one entrance monument or graphics on a whole fleet, we help you pick the right type of sign and build it to last.

    East Cobb is unincorporated, so Cobb County reviews and permits every sign. The county caps subdivision entrance signs at 64 square feet and eight feet tall, with a limit of two permanent signs per entrance. On top of that, most HOA boards, school administrations, and church committees have their own design standards. We clear the county permit and your board's design standards before we build, so nothing stalls once the sign is underway. You can review proofs and compare materials at our Canton Rd showroom, or handle everything by email. Either way, we install with our own team.

    What to know before you order a sign in East Cobb, GA

    On an East Cobb sign, the build is rarely the hold-up; the approvals are. Because the area is unincorporated, Cobb County issues the permit. The county caps a residential subdivision or development sign at 64 square feet and eight feet tall, allows indirect lighting only, and limits an entrance to two permanent signs. On top of that, the neighborhood's own board or a campus committee usually has to bless the design first. We line up both before we cut a single panel, so the project never stalls on a step nobody mentioned.

    Unincorporated, so the county permits it

    East Cobb is not its own city, so Cobb County reviews the sign permit under its ordinance. A residential subdivision or development sign is held to 64 square feet, eight feet tall, indirect lighting, and at most two permanent signs per entrance. We draw to those numbers, so the application clears the first time.

    HOA and campus standards

    A subdivision board, a church, or a school usually keeps its own rules on materials, color, and scale, separate from the county. We pull those criteria up front and design to them, so the board's review is a yes rather than a redo.

    It should suit the street, not shout

    In settled neighborhoods off Johnson Ferry and Sandy Plains, a sign earns more by fitting in than by standing out. We pick materials and proportions that read as solid and intended, not loud.

    The Stakes

    AVOID THE RISKS

    Of choosing the wrong provider in East Cobb, GA

    Plenty of shops will build you a sign. Fewer will carry the county permit and the HOA approval and still stand behind the work years later. Choosing the wrong sign provider in East Cobb, GA can create lost trust, lost money, lost opportunity, and frustration.

    Lost Trust

    Homeowners and parents read a worn entrance monument or a peeling truck graphic in an instant. It makes a neighborhood or a business look like nobody is minding the details.

    Lost Money

    A shop that ignores the county's size and height caps or skips the HOA review can have the sign rejected after it is built. Then you pay again to pull it out and start over.

    Lost Opportunity

    A faded entrance or a hard-to-spot office sign costs you without a sound. Visitors miss the turn, and the referral that should have come your way goes somewhere easier to find.

    Frustration

    Trading emails with a board, waiting on a county clerk, and reworking a design you thought was settled wears anyone down. We carry all three and bring you one clean plan to sign off on.

    when your sign is complete!

    And see why we're consistently rated 5.0 stars on Google!

    3GM Signs did an amazing job creating gym signs for Kell High School's wrestling team! They have been Kell's sign producer for years and I completely understand why! The employees are kind, easy to talk to and incredibly knowledgeable on the different materials, font, size options...everything! Michael specifically was great with communicating with both myself and my husband, the head wrestling coach at Kell. We will continue to recommend and use 3GM Signs! Thank you so much!

    Sabrina Kuhn

    We were in a pinch with Kell marching band and they came through even faster and better than promised. Amazingly nice folks too!!

    Heather Galloway

    We desperately needed new subdivison monument signs and reached out to multiple vendors to explore our options. Michael with 3GM Signs promptly responded and walked us through the process step by step. We worked together and Michael provided multiple great options for us to choose from. Everything was installed right on time and looks absolutely incredible. Our residents could not be more pleased with the result. I would highly recommend 3GM Signs as we will definitely continue to work with them in the future to maintain our beautiful signs.

    Permits and local approvals

    Do You Need a Sign Permit in East Cobb, GA?

    In East Cobb, a permit comes ahead of the install for most signs, and since the area is unincorporated, it comes from Cobb County rather than a city. The county reviews each sign against its ordinance, which fixes how large and how tall a subdivision sign is allowed to be.

    The neighborhood usually weighs in too. A board, church, or school sets its own expectations for materials, color, and scale, so an East Cobb sign normally has to satisfy both the county and the association before it can go up.

    East Cobb is unincorporated, so signs here are permitted by Cobb County under its sign ordinance (Chapter 134, Article VI). Most signs need a permit before installation, filed through the county's Citizen Access portal or in person at Community Development on Powder Springs Street in Marietta. The county also caps residential subdivision and development signs at 64 square feet and eight feet tall. On top of the county rules, HOAs, schools, and churches typically have their own sign standards a design has to meet first.

    Start by confirming the property sits in unincorporated Cobb County, then gather any HOA, church, or school standards, since together they set the path. We are glad to check both and handle the county filing through Citizen Access for you.

    Already operating here? Your occupational tax certificate is a useful clue. If Cobb County issued your business license, your address is in unincorporated county and the county most likely handles your sign permit; if a nearby city issued it, that city probably does. We confirm the exact parcel before production.

    Which signs usually need a permit

    In East Cobb, the county usually requires a permit for permanent and community-facing signs. Run through these before production:

    • Subdivision and HOA entrance signs
    • Monument signs
    • Permanent wall and building signs
    • Directional and property signs
    • Illuminated signs

    How the permit process works

    For an East Cobb sign that needs a county permit, expect these steps:

    • Confirm the property is in unincorporated Cobb County.
    • Gather HOA, church, school, or landlord sign standards.
    • Submit the permit and scaled drawings on Cobb County's Citizen Access portal.
    • Do not install until the county permit is in hand.

    How 3GM keeps your permit on track

    We have prepared permit-ready and HOA-ready drawings for East Cobb neighborhoods and campuses since 1985, so the requirements stay on our desk instead of yours. How we keep it moving:

    • We confirm the address is in unincorporated Cobb County and identify the HOA or property standards before we build.
    • We prepare the scaled drawings the county expects, including dimensions, materials, placement, mounting method, colors, and illumination, and file them through Citizen Access.
    • We design subdivision and campus signs to the community's standards and the county's size and height limits, so both approvals go smoothly.
    • Because we work across East Cobb and nearby Marietta every day, we know where neighborhood projects tend to stall and plan around it.

    What to confirm before we build your East Cobb, GA sign

    • Because East Cobb is unincorporated, Cobb County reviews the sign permit rather than a city.
    • Cobb County requires permits for many signs and files them through its Citizen Access portal or at Community Development, 1150 Powder Springs St in Marietta.
    • Residential subdivision and development signs are limited to 64 square feet and eight feet in height under the county ordinance.
    • HOAs, churches, schools, and landlords usually have their own sign standards on top of the county rules.

    Official city and county sources

    Check both permit paths and sign ordinances

    Use the Cobb County sources for East Cobb, since the area is unincorporated. If a specific address falls inside a nearby city, that city's permit process and sign ordinance apply instead.

    Permit requirements can change. Always verify the current Cobb County rules and any HOA or property standards for the exact address before installation.
