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.
