Macomb County, Michigan: Government and Services

Macomb County is Michigan's third most populous county, with a population exceeding 880,000 residents according to the U.S. Census Bureau. Its governmental structure, services, and administrative functions operate under the framework established by Michigan's county government statutes and the 1963 Michigan Constitution. This page covers the organizational structure of Macomb County government, the primary service delivery mechanisms, the scenarios in which residents and businesses interact with county agencies, and the boundaries that distinguish county authority from state and municipal jurisdiction. For a broader orientation to Michigan government and public services, see the main reference overview.

Definition and scope

Macomb County operates as a general law county under Michigan's county government statutes codified in the Michigan Compiled Laws (MCL), Chapter 46. The county seat is Mount Clemens. Macomb County is bordered by St. Clair County to the north, Lake St. Clair to the east, Wayne County to the south, and Oakland County to the west.

The county's governing body is the Macomb County Board of Commissioners, which consists of 13 elected members serving four-year terms. The Board holds legislative and budgetary authority over county operations. In addition to the Board, Macomb County elects a set of independent row officers:

  1. County Executive
  2. Prosecuting Attorney
  3. Sheriff
  4. County Clerk/Register of Deeds
  5. County Treasurer
  6. Public Works Commissioner

This elected structure distinguishes Macomb from charter counties in Michigan. The county has not adopted a home rule charter, meaning its authority derives directly from state statute rather than a locally ratified governing document.

Scope limitations: This page addresses Macomb County government functions. It does not cover the independent municipalities within its borders — including the cities of Warren, Sterling Heights, Clinton Township, or Roseville — which operate under separate municipal charters. For a structural comparison of county versus municipal authority in Michigan, see Michigan county government structure and Michigan municipal government.

How it works

County service delivery in Macomb County is organized across departments that report either to the County Executive or to independently elected officials.

The County Executive oversees executive branch departments including Planning and Economic Development, Health and Community Services, and Public Works administration. The executive holds veto authority over Board of Commissioners resolutions, subject to override.

The Board of Commissioners controls the annual county budget, authorizes contracts, and sets millage rates subject to state tax limitation statutes under the Headlee Amendment to the Michigan Constitution.

Core service categories include:

  1. Public health — administered through the Macomb County Health Department, which enforces state public health codes under MCL Chapter 333 (Michigan Public Health Code), manages communicable disease response, and operates environmental health inspection programs.
  2. Property records — the County Clerk/Register of Deeds maintains land transfer records, vital records, and election administration for unincorporated areas.
  3. Law enforcement and corrections — the Macomb County Sheriff operates the county jail and provides patrol services in townships that contract with the county.
  4. Circuit Court — the 16th Circuit Court sits in Macomb County, handling felony criminal cases, civil cases exceeding $25,000, and family division matters including custody and protective proceedings.
  5. Probate Court — administers estates, guardianships, and mental health commitments under MCL Chapter 700.
  6. Public infrastructure — the Public Works Commissioner oversees drain infrastructure across roughly 1,400 miles of regulated drains under the Michigan Drain Code (MCL Chapter 280).

State agencies operate parallel to county government within Macomb County. The Michigan Department of Health and Human Services administers Medicaid eligibility and child protective services through a local district office. The Michigan Department of Transportation maintains state trunk line highways, while the county road commission handles county primary and local roads.

Common scenarios

Residents and businesses engage Macomb County government across four primary contexts:

Property transactions: Transfer of real property requires recording with the Register of Deeds at the Macomb County Clerk's office in Mount Clemens. The county Treasurer enforces delinquent property tax collection; under MCL 211.78, property tax foreclosure proceedings are initiated at the county level after two years of delinquency (MCL 211.78).

Land use and development: Unincorporated areas of Macomb County fall under township zoning ordinances administered by the relevant township, not the county. The county Planning and Economic Development department coordinates regional planning but does not exercise direct zoning authority over incorporated municipalities. See Michigan township government for township-level land use authority.

Judicial proceedings: Felony arraignments, civil litigation, and family court matters are filed with the 16th Circuit Court. Misdemeanor matters below circuit court jurisdiction are handled by one of Macomb County's district courts, organized across four judicial districts.

Health and social services: Applications for state-administered benefit programs — including the Family Independence Program and Medicaid — are processed through the MDHHS Macomb County office, not through county-administered departments.

Decision boundaries

Determining which governmental entity has authority over a given matter in Macomb County requires distinguishing across three layers:

Matter Governing Authority
Felony criminal prosecution Macomb County Prosecuting Attorney / 16th Circuit Court
State benefit eligibility MDHHS district office (state agency)
Township road maintenance Macomb County Road Commission
State trunk line highways Michigan DOT
Municipal zoning Individual city or township
Drain and watershed infrastructure Macomb County Public Works Commissioner
Property tax delinquency Macomb County Treasurer
Vital records (births, deaths) Macomb County Clerk

The distinction between county and state authority is especially significant in health and human services. The county Health Department enforces local public health orders and environmental inspections, while MDHHS administers income-based assistance programs under state and federal mandates. These two agencies operate in parallel and do not share a unified application portal.

For matters involving state licensing — including contractor registration, professional licenses, or business entity filings — authority rests with the Michigan Department of Licensing and Regulatory Affairs, not with Macomb County government. Similarly, election administration for state and federal offices is supervised by the Michigan Secretary of State, with county and local clerks serving as administrative partners.
