The Illinois General Assembly is scheduled to return to Springfield for the 2026 Veto Session on November 17–19 and December 1–3. In advance of these six legislative days, ISACo has created this resource page to help county officials stay informed about legislation and policy issues that could be considered during the Veto Session.
The page highlights bills and proposals of particular relevance to Illinois counties, including measures that may affect county authority, operations, finances and responsibilities. Resources will include bill information, ISACo analyses and policy briefs, legislative updates and other materials intended to help county officials understand the potential local impact of these proposals.
ISACo will update this page as new information becomes available and legislative priorities evolve leading up to and throughout the Veto Session. County officials are encouraged to check back regularly for the latest information.
The POWER Act
The POWER Act (HB 5513, Representative Gabel, D-Evanston) is a comprehensive energy and utility reform proposal intended to address Illinois’ growing energy demands, grid reliability and the development of new energy infrastructure. The legislation establishes new requirements affecting energy generation, transmission, storage and large energy users, including data centers. Of particular concern to counties, the legislation contains several new mandates on local governments as well as provisions that preempt or restrict local government authority over certain energy-related facilities and activities. These provisions could affect county regulatory responsibilities, land-use authority, administrative processes and costs. The following resources further explain the POWER Act and county concerns.
The BUILD Act
The BUILD Act is a comprehensive housing proposal intended to increase housing supply by establishing statewide standards affecting residential zoning, permitting, accessory dwelling units, parking requirements and building codes. Among other provisions, the legislation would establish minimum residential densities, require municipalities to allow accessory dwelling units, create alternatives to local plan review and inspection processes, and permit certain residential buildings of up to six stories to use a single stairway when specified safety requirements are met. Of particular concern to counties and other local governments, the legislation includes state mandates and preemptions of local authority, including restrictions on local building-code authority applicable to counties. These provisions raise broader concerns regarding state limitations on locally adopted zoning, building, permitting and development standards.
