Thinking about rooftop solar or a home battery but worried the permits will slow you down? You’re not alone. You want the savings and resiliency without surprises, redlines, or long waits. This guide walks you through exactly who approves what in Kennesaw, what to collect before you sign a contract, the step-by-step process, and the timelines you can expect. Let’s dive in.
If your home is inside City of Kennesaw limits, the City’s Development Services and Building & Inspections is the authority that issues building and electrical permits, reviews plans, and conducts inspections for solar and batteries. If your home is in unincorporated Cobb County, Community Development and Building Inspections at the County level handles the same duties.
Your electric utility approves the interconnection to the grid and gives Permission to Operate after final inspections and any meter work. Common standards enforced include the National Electrical Code, NFPA 855 for energy storage, and UL listings such as UL 1741 for inverters and UL 9540 for battery systems. The Fire Department or Fire Marshal may review battery siting, clearances, signage, and access. If you have an HOA, secure approval before any visible rooftop work.
Have a site visit to confirm roof age and condition, shading, electrical service capacity, panel and meter layout, and attachment points. Gather your utility account details for the interconnection application.
If applicable, submit project drawings and finish samples to the HOA and wait for written approval before proceeding.
Your contractor prepares the permit set, which typically includes the application, a site plan, a single-line electrical diagram, equipment cut sheets, structural and attachment calculations, battery datasheets and instructions, inverter and disconnect details, clearance diagrams, and a labeling plan.
Many submittals are electronic. A licensed contractor or electrician usually pulls the electrical permit.
The reviewer checks code compliance, equipment listings, structural info, fire safety requirements for batteries, and required labels. You may receive an approval, approval with conditions, or corrections.
Submit the residential interconnection application to your utility with the single-line diagram and inverter specs. The utility issues Permission to Operate after the authority having jurisdiction finalizes inspections and any meter changes are complete.
After the final, submit proof of passed inspections to the utility. They complete meter work, if needed, and issue Permission to Operate.
Keep copies of the finaled permit, equipment cut sheets, and the interconnection approval for your records.
Collecting documents up front keeps your project moving. Share these with your contractor before you sign so the permit package is ready on day one.

Typical timelines vary by workload and jurisdiction, but these ranges are common for residential projects:
Common causes of delays and how to prevent them:
Before signing, confirm the contractor can pull City of Kennesaw or Cobb County permits, carries general liability and workers’ compensation, and has recent residential solar plus battery references in Cobb County or Kennesaw. Get a written scope that assigns who handles permitting, plan corrections, interconnection paperwork, meter upgrades, and inspection scheduling. Clarify equipment warranties, service expectations, and any manufacturer registration required for the battery.
Provide HOA approval early if needed, and share any planned roof work or large new electrical loads that could affect service capacity. Be available to sign utility forms and coordinate access for meter work and final inspections. Keep a clean record of your permit set, equipment cut sheets, and interconnection authorization for future reference.
Requirements and code editions can change, so confirm current plan review checklists, permit forms, and NEC edition with City of Kennesaw Development Services or Cobb County Building Inspections. Also verify your specific utility’s interconnection forms, net export rules, and meter change process.
If you’re timing solar or a battery around buying or selling, plan the permit and interconnection timeline alongside your move. A smooth closeout with clear documentation helps you share accurate system details with future buyers and sets expectations for utility billing changes after PTO.
