Commercial General Contractor in Atlanta, GA

Family-owned commercial general contractor in Atlanta since 1999. Tenant improvements, restaurant and retail buildouts, office renovations, warehouse conversions — typically $50K–$500K. Tenants, operators, and brokers call us when a space has a date on it and the lease clock is already running.

Atlanta is home base. The office is on Oakcliff Road, and most interiors we run start inside the Perimeter or one county over. The work is the same as it is anywhere: walk the space, price the actual conditions, pull the permits, build. What changes here is the jurisdiction. City of Atlanta is not Fulton County. A Gwinnett address is not a Cobb address. Getting that wrong is how opening dates slip before a crew ever shows up.

If you have a suite, a storefront, or a box that has to be occupiable, that's the call. Under $50K you're usually better with a handyman and we'll tell you so. Over $500K you probably want a firm with a project-management department. Right in the middle is where we do our best work.

Permitting in Atlanta (City vs county)

Projects inside the City of Atlanta are permitted through the city’s Office of Buildings, not Fulton County — the city is its own authority having jurisdiction. Commercial interior work generally requires a building permit plus separate electrical, mechanical, and plumbing permits, and a change of occupancy triggers additional review. Confirm current requirements with the City of Atlanta Office of Buildings for your specific address.

Treat that as the starting map, not the permit. What actually gets pulled, and in what order, depends on the scope.

  • Building permit for the physical work — walls, doors, ceilings, anything structural.
  • Separate trade permits for electrical, mechanical, and plumbing, usually pulled by the licensed trade doing that work.
  • A change of occupancy — retail to restaurant, office to clinic, storage to assembly — is a different review, not a finish upgrade. Expect more scrutiny on exiting, restrooms, ventilation, and accessibility.
  • Fire marshal review is often a separate track from building review. It can be the long pole. Do not assume it runs automatically in parallel.

Metro jurisdictions we work

We work Atlanta and the surrounding counties. The pattern is consistent even when the office is not: if the address sits inside a city, that city usually permits the job. Unincorporated addresses go through the county. Confirm the AHJ by address, not by mailing city.

  • City of Atlanta

    Office of Buildings. Own AHJ — not Fulton County.

  • DeKalb

    County process in unincorporated DeKalb; cities inside DeKalb permit their own.

  • Gwinnett

    County plan review in unincorporated Gwinnett; Duluth, Lawrenceville, Suwanee and others run their own.

  • Cobb

    County Community Development in unincorporated Cobb; Marietta, Smyrna, Kennesaw permit their own.

  • North Fulton cities

    Alpharetta, Sandy Springs, and neighboring cities are their own municipalities. They do not permit through Fulton County.

We do not quote AHJ review SLAs. Review time is the jurisdiction’s, not ours. The orientation we give clients: hope for about two weeks, expect about four, and confirm the current window with the authority that actually has your address. Anything faster is icing.

Cost and timeline orientation

A per-foot average is a sanity check, not a budget. The number that matters is built from your space and your scope. Typical interiors we run land in these bands — then a site walk replaces the band with a number.

Construction duration for this size of interior is usually the predictable part. Permitting and long-lead items move the date. What a TI actually costs per square foot · How long a commercial buildout takes.

Common questions

Is a City of Atlanta project permitted by Fulton County?
No. Projects inside the City of Atlanta go through the City of Atlanta Office of Buildings, not Fulton County — the city is its own authority having jurisdiction. Unincorporated Fulton and some north Fulton cities run a different process. Confirm which AHJ covers your exact address before you plan the schedule.
Do I need a permit for a small office remodel in Atlanta?
Usually yes if you are moving walls, changing electrical, or touching mechanical or plumbing. Paint and carpet often do not require one. Ask the building department about your specific scope before work starts — doing permit-required work without one is expensive to unwind.
What does a tenant improvement or restaurant buildout typically cost?
Most tenant improvements we do land in the $50K–$300K range. Most restaurant buildouts land in the $100K–$500K range, driven more by the kitchen than the dining room. Our overall sweet spot is $50K–$500K. The only number worth budgeting against is a scoped estimate from a walk of your space.
How long from a site walk to certificate of occupancy?
A site walk and estimate are days, not weeks, on most interiors. Construction for this size of job is fairly predictable. Permitting is the wild card: hope for about two weeks, expect about four, and confirm with the AHJ for that address. Punch, finals, and CO are days plus inspector availability. Plan the opening off the CO date, not the last day of construction.
Where do you work besides Atlanta?
Atlanta is home base. We work the metro — DeKalb, Gwinnett, Cobb, north Fulton cities — and commercial interiors across Georgia, Tennessee, Alabama, and South Carolina. Same $50K–$500K interiors. Call and we will tell you if the address is a fit.
Who usually calls you on an Atlanta job?
Tenants with a lease clock, operators opening a location, and brokers or property managers who need a GC they can hand a deal to. If the space has to be ready and the number has to hold, that is the call.
