Permitting in Gwinnett, Cobb, and Fulton

Permitting is the part of a commercial buildout most likely to move your date, and it works a little differently in every jurisdiction. If you are building across Metro Atlanta, here is a practical orientation to the three counties you are most likely to be in. Treat this as background, not legal advice — always confirm current requirements with the authority having jurisdiction for your specific address.

The thing they have in common

A commercial interior buildout generally requires a building permit and, depending on scope, separate trade permits for electrical, mechanical, and plumbing. A change of occupancy — turning retail into a restaurant, say — triggers additional review and often pulls in accessibility and life-safety upgrades. The bigger the change of use, the longer and more involved the review.

Where jurisdictions differ

• Municipal vs. county authority — an address inside a city (Alpharetta, Marietta, Sandy Springs, Duluth) is usually permitted by that city, not the county, and the city sets its own process and timeline. The same street can cross a jurisdiction boundary.
• Submittal and review process — some jurisdictions run fully online submittals with predictable review windows; others are slower or require more in-person coordination.
• Inspection scheduling — availability of inspectors varies, and inspection backlogs are a real schedule factor near completion.
• Local requirements — grease interceptor sizing, fire marshal review, and site-related requirements can differ meaningfully from one county or city to the next.

The practical takeaway

Know which authority actually has jurisdiction over your address before you plan the schedule, and start the permit conversation early. The difference between a smooth permit and a painful one is rarely the fee — it is whether the plans anticipated what that specific jurisdiction was going to ask for.
