Quick actions

Cobb County’s Community Development Agency combines building and development, inspections, planning, zoning, erosion control, and code-enforcement services. The county’s online inspections page specifically identifies the permitting jurisdiction as the unincorporated areas of Cobb County. Marietta, Smyrna, Mableton, and other incorporated communities may administer their own permits, so verify the municipal boundary first.

Cobb County building permits and plan review

The agency’s building and development services cover residential and commercial construction, additions, remodeling, trade work, and related development approvals. Cobb County’s official code requires a permit before covered building, electrical, mechanical, plumbing, or gas construction begins. Zoning and planning review is handled through the Community Development Agency and its Unified Development Code resources.

Inspections, code compliance, and occupancy

The Cobb Citizen Access portal lets applicants search permit applications and schedule inspections. The county also supports inspection scheduling by text message. After signing in online, applicants must open the building-permit record, choose Inspections, and then select Schedule or Request an Inspection. Final inspections and any required fire, zoning, or other approvals should be complete before the county issues the applicable occupancy approval.

Field work & closeout

Building Inspections & Code Compliance in Cobb County

Most permitted work must remain accessible for inspection at defined stages. Before scheduling, check your permit record for the required inspection sequence and make sure the site is safe and ready. Final inspections can be especially important for code compliance and a certificate of occupancy.

Helpful preparation

Keep the permit card or approval number available, confirm the property address, and ask the official office about lead times or reinspection fees.

Planning & review

Zoning and Plan Review Requirements

A building permit is not always the only approval your project needs. Zoning guidelines may affect use, setbacks, height, parking, signage, or lot coverage. Residential and commercial building permits can also follow different plan review tracks, so confirm the correct path before investing in a full plan set.

For a project in Cobb County, start with the official department below and ask which zoning, planning, conservation, or fire review approvals apply to your address.
