What county commissioner district am I in?

Michigan county commissioner district lookup — all 83 counties, free, by address, ZIP, or a tap on the map.

← Back to the map

Every Michigan county is governed by an elected board of commissioners, and every commissioner is elected from a single district — 619 districts across all 83 counties, on boards of five to 21 seats. The tool finds the district that covers any point in the state, names its county, shows the population it was drawn on, and names your commissioner, saying where that name comes from.

Where the names come from

For most counties, the card's name is read every week from the county's own board page, so it follows the board as members leave and are replaced. Where a county's page cannot be read, the card names the person the State of Michigan certified as the winner of the November 2024 election for that district instead. It labels that person "Elected Nov 2024" rather than "Commissioner", and adds a sentence saying they won the seat then and may not hold it now. Where a county's own page lists a district with no person in it, the card says so and names nobody.

The state's own district map is not used for names, and the paragraphs below are why.

The State of Michigan's own district layer carries a commissioner's name and party on every one of its 619 polygons, which looks like a free roster. It is not one. The dataset's own description says the values were derived from the canvassed November 2024 election results — so the column is a list of certified election winners, not of the people in office now. That is why it is filled in for every district: a district always has a winner. The fill rate is evidence against maintenance, not for it.

Measured on 3 September 2026: across twelve counties read district by district against their own board pages (123 districts), and about forty more in a second pass, the state's column named the right person 93.5% of the time — and every miss ran the same direction, the layer naming the 2024 winner and the county naming their replacement. One Wayne County district still named a commissioner who had died in June 2025. Four more rows misspell a real surname.

So that column is dropped when the boundaries are built, and the builder refuses to write the file if it ever reaches it. A county's own board page comes first. The certified results are used only where no board page can be read, and the card says which of the two it is showing.

What the lookup shows

Select any point in Michigan and the commissioner district card shows the district, the county, and the district's population from the 2020 apportionment it was drawn on. 611 of the 619 districts carry a population figure in the state's data; Baraga's District 1 and the seven Cheboygan districts do not, and the row is simply absent there rather than invented.

Above those rows the card names your commissioner, with a phone number or e-mail address where the county publishes one. A name taken from the certified 2024 results comes with a row saying so. Where nobody is named for a district, the card says why and links your county's board page as the place to ask.

Commissioner district, township, city

Michigan layers its local government differently from most states, and three maps that cover the same address answer three different questions.

A village is not a fourth map: every Michigan village sits inside a township and is a separate government on top of it, not instead of it. The map's City or Village card names the village; the township card still applies.

Where the boundaries come from

District boundaries come from the Michigan Department of State, Bureau of Elections — 2021 County Commissioner Districts, the statewide compilation of the plans county apportionment commissions file with the state. All 83 counties are in one service, pre-built and shipped with the app so the lookup works offline and never waits on a server. The layer is named for its 2021 adoption year and labelled 2022 by the state's own viewer for the first election held under it — two names, one layer. The state's record for the dataset says it is a public record with no restrictions on its use, reproduction or distribution. Every source is on the sources & data layers page. The map is free, requires no login, and sets no tracking cookies.

Not for legal or official use. Boundary data comes from public sources that explicitly disclaim legal precision. Confirm district assignments with the relevant government office before relying on them for anything official.

Every board of commissioners, county by county

Every Michigan county whose roster this project has: 83 counties, 617 people, each name from the county's own board page or, where that county's page says so, from the state's certified results of the November 2024 election.
