Permit Requirements for Kennesaw, Georgia
For home remodeling and renovation projects in Kennesaw, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Cobb.
Authority Having Jurisdiction (AHJ)
The governing body responsible for issuing building permits, reviewing plans, and conducting inspections varies depending on exactly where the property sits in Cobb:
- Within City Limits: The Kennesaw Building Department typically oversees all Kennesaw building, trade, and safety permits.
- Unincorporated Areas: Properties located outside of official Kennesaw boundaries are generally governed by the Cobb Building & Safety Division.
Common Remodeling Permit Triggers
Remodeling is a broad category, and permit requirements depend heavily on the scope of your work. While cosmetic updates—such as painting, installing new flooring, or replacing like-for-like kitchen cabinets—generally do not require approval in Georgia, you will almost certainly need a permit for the following:
- Space Conversions: Altering non-living spaces (such as finishing a basement, finishing an attic, or converting a garage) into habitable living areas.
- Structural Changes: Removing, adding, or modifying load-bearing walls, headers, or the roofline.
- Demolition: Extensive interior renovations or "gutting" a space often requires a specific demolition permit prior to or concurrent with the standard building permit.
- Systems Alterations: Rerouting plumbing pipes, adding new electrical circuits, or moving HVAC ductwork.

Unincorporated Areas
The provided search results do not contain specific information detailing separate permit requirements for unincorporated areas of Cobb County. However, the general building permit requirements for Cobb County would apply. For zoning-specific regulations in unincorporated areas, consulting the Cobb County Zoning Ordinance or the PropZone map may be necessary.
Demolition Permit Triggers During Remodeling
A demolition permit is required in Cobb County when the damage to a structure exceeds 25% of its total value, as determined by a county building inspector. A permit is also necessary if the demolition work is not part of a larger reconstruction permit. If a structure is demolished due to significant damage (e.g., fire or flood), it's crucial to consult with zoning and stormwater management departments before pursuing a demolition permit to understand current build-back requirements.
Permit Requirements for Converting Non-Living Spaces
Converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas requires a building permit in Cobb County. Depending on the scope of work, additional permits for plumbing, electrical, or mechanical systems may also be necessary.
- Garages: Converting a garage may require demonstrating alternative off-street parking provisions. The new living space must meet minimum square footage and ceiling height requirements, and include adequate egress and ventilation.
- Attics: Attic conversions must comply with current residential and energy codes, including insulation and ventilation standards. Access openings must meet specific size requirements.
- Unfinished Basements: Basements intended for living space must have a minimum ceiling height of 6'8" and at least one egress window or exterior door for emergency escape.
In all cases of converting non-living spaces, the new living areas must meet current building codes, including requirements for ceiling height, egress, ventilation, and insulation. Detailed building plans illustrating the proposed work are required for permit applications.

The following statewide building codes and regulations apply universally to all jurisdictions within Georgia:
Georgia Remodeler Legislation, Codes, and Guidelines
Georgia Building Codes for Remodelers and Residential Renovations
Georgia has adopted the 2024 International Building Code (IBC) and the 2024 International Residential Code (IRC) with state-specific amendments, effective January 1, 2026. The International Existing Building Code (IEBC) is also adopted as a permissive code, meaning its provisions are not mandatory unless specifically referenced by local governments. For renovations, the state now aligns with the International Existing Building Code (IEBC) framework, utilizing either the Prescriptive or Performance methods.
The primary state agency responsible for setting and enforcing these building standards is the Georgia Department of Community Affairs (DCA). Additionally, various divisions under the State Construction Industry Licensing Board, such as the Division of Electrical Contractors and the Division of Master and Journeyman Plumbers, administer standards for their respective trades.
Generally, minor cosmetic remodels that do not affect the building's performance or safety, such as painting or replacing flooring, may not require a permit. However, structural alterations, including the removal or alteration of load-bearing walls, or converting spaces like attics or basements into habitable areas, typically require permits and must comply with the adopted codes. Demolition guidelines are also in place, with specific requirements for asbestos notification and abatement before demolition can commence. Demolition permits are generally required for the destruction of any free-standing structure, though exceptions may exist for accessory buildings not used for human habitation or lacking utility connections.
