Minnesota Counties: Complete Government Structure Guide

Minnesota operates through 87 counties — exactly 87, a number that has remained unchanged since Roseau County was established in 1894. That administrative map covers everything from the dense urban grid of Hennepin County, home to Minneapolis and more than 1.2 million residents, to Lake of the Woods County in the far north, where the population sits around 3,800 and a portion of the county is only accessible through Canada. Understanding how counties function, what authority they hold, and how they differ from one another is foundational to understanding how Minnesota actually governs itself day to day.

Definition and Scope

Minnesota counties are political subdivisions of the state, created by and subordinate to state authority under the Minnesota Constitution and Minnesota Statutes Chapter 375. They are not autonomous governments — they execute state-mandated functions — but within that framework they hold substantial operational power over residents' daily lives.

The 87 counties collectively manage property tax administration, court administration, public health programs, social services, land use in unincorporated areas, and the maintenance of county road systems. The Minnesota Counties Overview page maps the full roster of counties with direct links to individual county profiles, making it the practical starting point for anyone navigating county-specific information.

Scope and coverage boundaries: This page covers the structure of Minnesota's county government system as established under Minnesota state law. It does not address municipal government (cities and townships operate under separate statutory authority), tribal governance (Minnesota's 11 federally recognized tribal nations operate under sovereign authority outside the county framework), or federal agencies operating within county boundaries. Counties in Wisconsin, Iowa, South Dakota, or North Dakota — states bordering Minnesota — are entirely outside the scope of this content.

How It Works

Each of Minnesota's 87 counties is governed by a Board of Commissioners, the size of which is set by statute. Most counties operate with 5 commissioners elected from geographic districts. Larger counties may expand — Hennepin County expanded to 7 commissioners — but the 5-member board is the statutory default under Minnesota Statutes §375.01.

The board functions as both the legislative and executive body. It adopts the county budget, sets property tax levies, enacts county ordinances, and appoints department heads. Below the board, a set of elected and appointed offices carry out daily administration:

County Auditor — manages elections, property tax records, and financial accounts
County Treasurer — collects taxes and manages county funds (note: many counties have merged this office with the auditor role under Minnesota Statutes §375A)
County Recorder — maintains land records, deeds, and mortgages
County Sheriff — provides law enforcement in unincorporated areas and operates the county jail
County Attorney — prosecutes criminal cases and provides legal counsel to the board
District Court — while judges are state employees, court administration is heavily county-funded

Property tax is the financial engine. Counties set a levy each year, which is applied against the assessed value of all real and personal property within county boundaries. The Minnesota Department of Revenue oversees property tax administration statewide (Minnesota Department of Revenue, Property Tax Division).

Common Scenarios

The county structure becomes visible to residents in predictable, recurring ways.

Property transactions route through the county recorder and auditor. A home sale in Washington County or Dakota County requires deed recording, transfer tax payment, and homestead classification — all handled at the county level before the transaction is legally complete.

Social services delivery is one of the most consequential county functions. Counties administer Minnesota's Medical Assistance (Medicaid) enrollment, child protection investigations, adult foster care licensing, and food support applications under contract with the Minnesota Department of Human Services. A resident in Stearns County and a resident in Ramsey County access the same state programs, but through different county offices with different staffing, wait times, and local policies within state parameters.

Land use in unincorporated areas falls entirely to the county. Once a parcel lies outside a city or township with its own zoning authority, the county planning and zoning department controls what can be built, subdivided, or operated. This has significant practical weight in rural counties like Aitkin County or Koochiching County, where the county is effectively the only land use authority for large swaths of territory.

Decision Boundaries

Not everything that looks like a county decision actually is one, and the line matters.

County vs. municipality: Cities and townships control land use, building permits, and local ordinances within their incorporated boundaries. A property inside the city of Rochester is under Olmsted County for tax and court purposes, but under Rochester's municipal government for zoning and building permits. Olmsted County and the city operate parallel systems on the same geography.

County vs. state agency: The Minnesota Department of Transportation maintains the state highway system; counties maintain the county state-aid highway (CSAH) network. The boundary between a state trunk highway and a county road is a formal jurisdictional line, not an informal one. Similarly, the Minnesota Pollution Control Agency holds permitting authority over environmental matters that county boards cannot override.

County vs. tribal nation: The 11 federally recognized tribes in Minnesota — including the Leech Lake Band of Ojibwe, the Red Lake Band of Chippewa Indians, and the Mille Lacs Band of Ojibwe — exercise sovereign governmental authority on tribal lands. County jurisdiction does not extend onto trust lands except in specific circumstances defined by federal law.
