Anne Arundel County Maryland Government: Structure, Services, and Administration

Anne Arundel County occupies a central position in Maryland's governmental landscape — it is the fourth most populous county in the state, with a 2020 U.S. Census count of approximately 588,261 residents, and it serves as the home of Annapolis, the Maryland state capital. The county operates under a charter form of government established in 1964, distinguishing it from Maryland's code counties and giving it expanded home rule authority. This page covers the county's administrative structure, the services it delivers, the boundaries of its jurisdiction, and the decision frameworks governing how residents and entities interact with county authority.

Definition and scope

Anne Arundel County is a charter county under Maryland local government law, one of ten Maryland jurisdictions operating under charter home rule as authorized by Article XI-A of the Maryland Constitution. Charter counties hold broader legislative and administrative authority than code counties — they may enact local legislation without seeking specific General Assembly authorization, within limits set by state law.

The county government is headquartered in Annapolis, though the City of Annapolis itself functions as an independent municipal government and is not administratively absorbed into county operations. This dual-jurisdiction structure — a county government and a separate municipal government sharing geography — is a persistent feature of Anne Arundel's administrative landscape. County services cover the unincorporated areas and extend to incorporated municipalities for functions not assumed at the municipal level. For broader context on how Anne Arundel fits within Maryland's governmental reference framework, see the Maryland Government homepage.

The county encompasses approximately 588 square miles of land area, including the western shore of the Chesapeake Bay, portions of the Baltimore-Washington metropolitan corridor, and the Patuxent River border with Prince George's and Howard counties.

How it works

Anne Arundel County operates under a County Executive–County Council structure. The County Executive serves as the chief executive officer, elected countywide to a 4-year term, with authority over the county budget, administrative appointments, and execution of county ordinances. The County Council functions as the legislative body, composed of 7 members — 5 elected by district and 2 elected at-large — also serving 4-year terms.

The administrative apparatus is organized into departments and offices reporting to the County Executive:

Department of Public Works — manages roads, bridges, stormwater infrastructure, and solid waste; responsible for approximately 1,700 miles of county-maintained roadway.
Department of Recreation and Parks — administers more than 140 county parks and recreation facilities.
Anne Arundel County Police Department — provides law enforcement services to unincorporated areas and operates under county charter authority separate from municipal police forces.
Department of Health — delivers public health services under delegated authority from the Maryland Department of Health, coordinating local health programs including communicable disease surveillance and environmental health inspection.
Office of Finance — administers property tax billing, collection, and budget execution under county fiscal rules.
Department of Planning and Zoning — reviews development proposals, enforces zoning ordinances, and administers subdivision regulations for unincorporated county land.

The county property tax rate and annual operating budget are set through a legislative process: the County Executive submits a proposed budget to the County Council, which must adopt a final budget before the start of the fiscal year on July 1. The fiscal year 2023 adopted operating budget totaled approximately $1.9 billion (Anne Arundel County Office of Budget).

Common scenarios

Service interactions with Anne Arundel County government typically fall into the following categories:

Property tax and assessment disputes: Property owners interact with the County's Office of Finance for billing inquiries and may appeal assessments through the Maryland State Department of Assessments and Taxation (SDAT) — a state-level function, not a county function, though records are coordinated locally.
Building permits and zoning approvals: Applications for construction, renovation, or land use changes run through the Department of Inspections and Permits, which enforces county codes aligned with Maryland building standards.
Public school administration: Anne Arundel County Public Schools (AACPS) is a separate governmental entity governed by the Board of Education, not by the County Executive or Council, though county government funds a substantial portion of the AACPS operating budget.
Utility services: The county operates a water and wastewater utility serving approximately 200,000 customer accounts, administered through the Department of Public Works.
Emergency management: The Anne Arundel County Office of Emergency Management coordinates local emergency preparedness in alignment with the Maryland Emergency Management Agency.

Decision boundaries

The scope of Anne Arundel County government authority has defined limits. County ordinances apply only within county jurisdiction — state law supersedes where the General Assembly has preempted local action, including in areas such as firearms regulation, certain labor standards, and environmental permitting thresholds governed by the Maryland Department of the Environment.

Annapolis, as an incorporated municipality, operates its own city government with independent taxing authority, police department, and zoning jurisdiction. County services generally do not extend into Annapolis city limits for functions the city administers directly. Similarly, the municipalities of Laurel (partially within the county), Linthicum Heights, Severna Park, and Glen Burnie (unincorporated communities) occupy different administrative positions with varying service delivery configurations.

Judicial matters arising within the county are heard in the Circuit Court for Anne Arundel County and the District Court, both of which are state courts operating under the Maryland Judiciary — not county government entities.

Federal land within the county, including portions of the U.S. Naval Academy in Annapolis and Fort Meade in the county's northern region, falls outside county zoning and regulatory authority. Federal enclave jurisdiction applies to those installations. County services such as emergency response may operate under mutual aid agreements at such locations but without regulatory authority.

Scope and coverage limitations

This page covers Anne Arundel County government as a distinct administrative unit within the Maryland state system. It does not address Annapolis city government operations, state agency functions administered from Annapolis, federal operations at military or federal installations in the county, or the independent governance of Anne Arundel County Public Schools. Regulatory actions by Maryland state agencies — including the Maryland Department of Transportation, Maryland Department of Labor, and Maryland Department of Agriculture — apply within county geography but are administered at the state level and are not covered by this page.
