DeKalb County Georgia Government: Structure and Services

DeKalb County operates under a commission-executive form of government, making it one of the more complex local government structures among Georgia's 159 counties. The county serves a population exceeding 770,000 residents (U.S. Census Bureau, 2020 Decennial Census), spanning both dense urban corridors adjacent to Atlanta and suburban communities to the east. This reference covers the governing structure, primary service divisions, functional decision-making boundaries, and the relationship between DeKalb County government and state-level authority.

Definition and Scope

DeKalb County is a county government established under Georgia law, specifically operating under the authority granted by the Georgia State Constitution and Title 36 of the Official Code of Georgia Annotated (O.C.G.A.), which governs counties and municipal corporations. DeKalb is classified as a urban-suburban county within the Atlanta Metropolitan Statistical Area and is subject to the same constitutional framework that structures all county governments in Georgia.

The county seat is Decatur. DeKalb County government is distinct from the City of Decatur, the City of Atlanta (which extends into DeKalb), and the approximately 14 municipalities incorporated within county boundaries — including Brookhaven, Tucker, Dunwoody, and Doraville. County government services operate across unincorporated DeKalb, which accounts for a substantial portion of the county's land area and population.

Scope and coverage limitations: This page addresses the structure and functions of DeKalb County government as a unit of Georgia local government. It does not address the internal governance of municipalities within DeKalb County, nor does it address federal agencies operating within county boundaries. Georgia state agency operations — such as those administered by the Georgia Department of Public Health or the Georgia Department of Transportation — intersect with county functions but remain outside the county government's direct authority. Federal law and state law supersede county ordinances where conflicts arise.

How It Works

DeKalb County operates under a CEO-Commission form of government, established by a local constitutional amendment and codified in state law. This structure divides executive and legislative authority:

  1. Chief Executive Officer (CEO): An elected position carrying executive authority over county operations, budget administration, and departmental oversight. The CEO appoints department heads and serves a 4-year term.
  2. Board of Commissioners: A 7-member legislative body. Six commissioners represent individual super-districts; a presiding officer serves at-large. The Board holds authority over appropriations, zoning decisions, and policy ordinances.
  3. Elected Row Officers: DeKalb County elects a Sheriff, Clerk of Superior Court, Tax Commissioner, Probate Court Judge, Magistrate Court Chief Judge, and Solicitor-General independently of the CEO, distributing accountability across offices.
  4. DeKalb County Superior Court: Part of the Stone Mountain Judicial Circuit, operating within the state judicial structure under the Georgia Judicial Branch.
  5. DeKalb County School District: Governed by an independently elected Board of Education, distinct from the county commission structure. The School Superintendent reports to the Board, not the CEO.

The county budget process requires the CEO to submit a proposed annual budget; the Board of Commissioners holds appropriation authority and must adopt a balanced budget in compliance with O.C.G.A. § 36-81-3. Property tax millage rates are set annually by the Board following state-mandated public hearings (O.C.G.A. § 48-5-32).

Decision Boundaries

The CEO-Commission model creates defined separation between executive and legislative functions, which determines how different categories of decisions are processed:

Decision Type Authority
Budget adoption Board of Commissioners
Department appointments CEO
Zoning map amendments Board of Commissioners (following planning staff review)
Law enforcement operations Sheriff (independent elected officer)
School district policy Board of Education (independent)
State road maintenance Georgia DOT, not county
Tax rate (millage) Board of Commissioners, subject to state rollback rules

Disputes between the CEO and Board of Commissioners regarding budget line items have historically required resolution through the county's legal framework and, in unresolved cases, through Georgia Superior Court jurisdiction. Municipalities within DeKalb retain their own zoning, policing, and taxing authorities — county authority does not extend into incorporated areas for most service categories.

DeKalb County's 2023 adopted general fund budget was approximately $700 million (DeKalb County FY2023 Adopted Budget), reflecting the scale of services delivered across public safety, infrastructure, health, and administration.
