Michigan County Government Structures and Administration
Michigan is divided into 83 counties, which serve as the state's primary administrative divisions. These local government entities play a critical role in providing essential services, particularly in unincorporated lands. While their influence is significant in these areas, the power of county government is greatly diminished in incorporated places that have been granted home rule—the legal authority for a local municipality to govern its own local affairs.
Generally, county governments in Michigan focus on operating the local criminal justice system, maintaining vital records, and partnering with the state to deliver social services. Because most local services are provided at the city or township level, counties have limited autonomy and lack general police power, meaning they cannot pass ordinances that contradict state or municipal laws.

The Structure of County Government
The standard framework for county government is the county board of commissioners. This body acts as the legislative branch and holds some executive powers. To ensure the administration of law and finance, the state constitution requires several elected executive officers, including:
- Sheriff
- County Clerk
- County Treasurer
- Register of Deeds
- Prosecuting Attorney
Types and Forms of Administration
The specific way a county is governed depends on its designated "type," which then dictates the available "form" of government. There are three primary types and six possible administrative forms, ranging from the traditional board of commissioners to the appointment of a chief administrative officer.
| County Type | Governing Authority | Key Characteristics | Examples |
|---|---|---|---|
| General Law | Board of Commissioners | Most common; shared executive/legislative functions. | 79 of 83 counties |
| Optional Unified | Manager or Executive | Centralized structure under Public Act 139 of 1973. | Bay, Oakland |
| Charter | Charter-defined authority | Most flexible; limited home rule under Public Act 293 of 1966. | Macomb, Wayne |
Detailed Analysis of County Types
General Law Counties
General law counties are the most numerous in the state. In these counties, the board of commissioners shares executive and legislative duties with other elected and appointed officials. While most operate under a regular board form, 61 have opted for either a county administrator or a county controller to handle day-to-day operations.
The primary difference between these two roles is the ease of removal: a county administrator can be dismissed by a simple majority of the board, whereas a county controller requires a two-thirds majority for dismissal.
Optional Unified Counties
Organized under Public Act 139 of 1973, this type streamlines administration. It offers two alternatives: Alternate A, featuring an appointed county manager (a bureaucrat serving at the board's pleasure), and Alternate B, featuring an elected county executive (a political official with a set term and veto power). Bay and Oakland counties both utilize the Alternate B executive form.
Charter Counties
Charter counties, organized under Public Act 293 of 1966, enjoy the highest level of flexibility through limited home rule. The board size must be between 5 and 21 members, regardless of the county's population.
- Counties with population ≥ 1,500,000: May choose between an elected partisan county executive (with veto power) or a chief administrative officer appointed by the board for a four-year term (removable only by a two-thirds majority).
- Counties with population < 1,500,000: Only the elected county executive option is permitted.
Macomb and Wayne counties are both organized as charter counties with elected executives.
The Role of Road Commissions
Although integrated into the county framework, the county road commission is a separate, independent unit of government. Managed by a board of three to five members, these commissions are responsible for maintaining roads, bridges, and roadside ditches, as well as snow removal.
A road commission can be dissolved and its duties transferred to the general county government. This occurs via a resolution by the board of commissioners for appointed commissions, or through a public election for elected commissions.
