What does the DuPage County Board do?
The DuPage County Board serves as the central governing body for DuPage County, Illinois, one of the most populous and affluent suburban counties in the Chicago metropolitan area, home to nearly one million residents. Located west of Chicago, DuPage County blends thriving business corridors, family-friendly communities, and unincorporated areas.
The County Board acts as both the legislative and executive authority, exercising powers not delegated to other independently elected officials such as the Sheriff, State’s Attorney, or Coroner.
DuPage County Board Structure and Leadership
The Board consists of 18 members elected from six geographic districts, with three representatives per district serving four-year terms. Voters also elect a County Board Chair countywide every four years. The Chair oversees policy implementation, prepares the annual budget and meeting agendas, supervises county departments under the Board, and presides over meetings.
As of 2026, Deborah A. Conroy (often referred to as Deb Conroy) holds the position of Chair. First elected in 2022, she is the first woman and the first Democrat in over 75 years to lead the Board. Board members participate in a committee system that reviews issues in depth before the full Board votes. Regular meetings occur at the Jack T. Knuepfer Administration Building in Wheaton, with agendas, minutes, and live streams available online for public transparency.
DuPage County Board Core Powers and Responsibilities
Under Illinois law (IL constitution and 55 ILCS Article 5), the DuPage County Board holds broad authority over county operations. Its primary duties include:
Fiscal Management and Stewards of Tax Dollars:
The Board is responsible for levying sales taxes, property taxes, adopting the annual budget, appropriating funds, issuing bonds (when required), and managing county finances. Revenue comes mainly from sales taxes, then property taxes, with additional support from other taxes, services, and more.
Legislative and Regulatory Authority:
The Board enacts ordinances and resolutions that govern countywide matters or specifically apply to unincorporated areas. This includes zoning, land-use planning, licensing, transportation and infrastructure, environmental controls, public health, and regulatory policies. It can also include codifying ordinances into a county wide code.
Administrative Oversight:
It establishes county departments and offices, manages county property, enters into contracts, oversees facilities such as the courthouse and jail, and directs departments that report to the Chair.
Special review:
The Board looks at appeals about planning, land use, and building issues.
The Board does not control all county functions. Independent elected officials handle areas like law enforcement and courts, but they provide funding and set overarching policy direction.
