Do I need a permit for interior remodeling in Kennesaw?

Permit may be required

It depends. Whether interior remodeling needs a permit in Kennesaw comes down to the details of your project.

Cosmetic work such as paint, flooring, or cabinet swaps is usually exempt, but moving walls, plumbing, gas, or electrical typically requires a permit. Fee is often based on project cost, so keep an accurate scope and cost estimate for the application. Cobb County's own permitting office is the Cobb County Development and Inspections, reachable on 770-528-1000 at https://www.cobbcounty.gov/community-development/building-development/permitting. Its online permit portal is https://cobbca.cobbcounty.gov/CitizenAccess/default.aspx. It issues permits for the unincorporated county. If your city does not run its own building department, and many smaller Georgia municipalities do not, this is the office that will handle the job. Each trade normally needs its own permit on top of the building permit, so ask which trade permits your scope will require. Code Sec. 18-66 requires a permit to alter or repair a building or to install, alter, replace or convert any electrical, gas, mechanical or plumbing system. Only ordinary minor repairs may be done without a permit, and only with the building official's approval. Basement finishes and garage enclosures are their own Residential Building Permit categories, each requiring a floor plan, a wall section and a posted energy code affidavit. Kennesaw amended the plumbing code (Sec. 18-132) so new fixtures must meet WaterSense-level flow limits: 1.2 gallons per minute for bathroom faucets, 1.8 for kitchen faucets, 2.0 for showerheads and 1.28 gallons per flush for toilets.
