Arlington Heights, Illinois Government: Village Structure and Services

Arlington Heights is the largest village in Illinois by population, with approximately 77,000 residents, and operates under a council-manager form of municipal government distinct from the mayor-council structure used by Chicago and many other Illinois cities. This page covers the village's governing structure, the services it delivers directly to residents, the boundaries of its jurisdiction, and how its authority compares to overlapping county and regional bodies. Understanding this structure matters for property owners, developers, businesses, and residents who need to know which government entity controls permits, taxes, public safety, and land use decisions within the village.

Definition and scope

Arlington Heights is an incorporated village in Cook County, Illinois, governed under the Illinois Municipal Code (65 ILCS 5), which sets the statutory framework for all Illinois municipalities. Its territorial jurisdiction covers approximately 16.6 square miles in the northwest suburbs of Chicago, roughly 25 miles from the Loop.

As a home rule unit under Article VII, Section 6 of the Illinois Constitution of 1970 (Illinois General Assembly), Arlington Heights holds expanded authority to regulate and tax beyond the default powers granted to non-home-rule municipalities. Home rule status, which attaches automatically to any Illinois municipality with a population exceeding 25,000, allows the village to impose local taxes, regulate land use, and enact ordinances without specific state enabling legislation — provided those ordinances do not conflict with state law.

Scope boundary and coverage limitations: This page covers the Village of Arlington Heights as a governmental entity. It does not address Cook County government functions (such as property assessment administered by the Cook County Assessor), Regional Transportation Authority oversight, or Township government functions carried out by Wheeling Township, which overlaps portions of the village's territory. Services provided by the Arlington Heights Park District, Township High School District 214, and Elementary District 25 fall outside the village government's jurisdiction — those are independent taxing bodies with their own elected boards.

How it works

Arlington Heights operates under a council-manager structure, which separates political authority from administrative management:

1. Village Board of Trustees — Six trustees and a village president are elected at-large to four-year staggered terms. The board sets policy, adopts the annual budget, approves ordinances, and levies property taxes.
2. Village Manager — Appointed by the board, the village manager handles day-to-day administration, oversees department directors, and implements board directives. This role is professional rather than political.
3. Village Clerk — An elected position responsible for maintaining official records, posting public notices, and administering election filings at the municipal level.
4. Village Attorney — Appointed counsel who advises the board and litigates on behalf of the village.
5. Standing Committees and Commissions — The Planning and Zoning Commission, Fire and Police Commission, and Board of Zoning Appeals provide advisory and quasi-judicial functions that feed recommendations to the board before final votes.

This council-manager model contrasts with the strong-mayor structure used in Chicago, where the Chicago Mayor's Office holds broad executive appointment powers and the mayor functions as the chief administrator in addition to a political leader. In Arlington Heights, the village manager insulates administrative decisions from direct electoral pressure, a design intended to promote operational continuity.

The village's fiscal year runs from May 1 through April 30. The annual budget is published and presented in public session before adoption, with the property tax levy submitted to Cook County by the last Tuesday in December as required by the Illinois Property Tax Code (35 ILCS 200/18-55).

Common scenarios

Residents and property owners most frequently interact with village government through the following situations:

• Building permits and inspections — Renovation, new construction, and demolition within village boundaries require permits issued by the village's Community Development Department, which enforces local zoning ordinances and adopts the applicable International Building Code edition by reference.
• Zoning and land use changes — Requests for rezoning, special use permits, or variances go first to the Planning and Zoning Commission, which holds public hearings, then to the Village Board for final action.
• Water and sewer service — Arlington Heights operates its own water distribution system, purchasing treated Lake Michigan water from the Northwest Water Commission, a joint agency serving northwest Cook County municipalities.
• Police and fire services — The Arlington Heights Police Department and Fire Department operate as village departments under the Village Manager's administrative structure. Sworn personnel are governed through the Fire and Police Commission under the Illinois Municipal Code.
• Local business licensing — Retail food establishments, contractors working within the village, and businesses operating in regulated categories require village-issued licenses separate from any Cook County or state licensing requirements.
• Property tax bills — The village levies a property tax, but the bill residents receive consolidates levies from the village, the park district, school districts, the township, and Cook County. The Cook County Treasurer collects and distributes all those levies.

Decision boundaries

Not every service or regulatory decision within Arlington Heights' geographic footprint belongs to the village government. Identifying who holds authority prevents misdirected inquiries and filing errors.

A key decision rule: if a facility, road, or service crosses municipal boundaries or operates as a special district, the village board has no direct authority over it, even if the facility sits inside village limits. The village does enter into intergovernmental agreements — a mechanism authorized under the Illinois Intergovernmental Cooperation Act (5 ILCS 220) — to coordinate with neighboring municipalities like Des Plaines, Mount Prospect, and Buffalo Grove on shared infrastructure and emergency response.
