📌 Georgia State Requirements

In addition to Atlanta's local rules, these state-level requirements apply:

• Rural GA: limited enforcement in some counties

🚫 Common Generator Permit Mistakes in Atlanta

• Installing generator too close to windows or HVAC return air intake — carbon monoxide hazard and code violation
• Transfer switch work without permit — major code violation
• Not sizing gas line for combined BTU load (if other gas appliances on same line)
• Skipping the concrete pad requirement — some jurisdictions require permanent pad for standby units

💡 Pro Tips from Contractors

• Get the electrical AND gas permits at the same time — saves a second trip to the building department
• Confirm setback distance from windows and doors before ordering — some HOAs and cities are stricter than code minimum
• Size the gas line for peak BTU load including all other gas appliances on the same line
• In CA/SoCal: check CARB compliance before ordering the generator unit — some models are not permitted in certain air districts

Notes specific to Atlanta:

• Georgia DCA (Department of Community Affairs) sets statewide code — NEC 2023, IRC 2024
• Atlanta metro suburbs (Marietta, Sandy Springs, Alpharetta, Roswell) have own permit offices — often faster than City of Atlanta
• State contractor licensing required
• Fulton County vs City of Atlanta — verify jurisdiction
