Illinois Housing Showdown: Suburbs Defy State’s Push for Density

ELMHURST, Ill. – May 15, 2026 – A coalition of suburban municipal leaders drew a firm line in the sand on Friday, escalating a burgeoning conflict with Springfield over the future of housing and development in Illinois. Gathering in a united front, leaders from DuPage County and seven other regional councils of government publicly challenged Governor JB Pritzker’s proposed Building Up Illinois Developments (BUILD) Act, a sweeping legislative package aimed at increasing the state's housing supply by expanding state control over local development standards.

Armed with new polling data suggesting strong resident opposition to state intervention, the mayors and managers are urging legislators to abandon the top-down mandate. Instead, they are calling for a collaborative approach that they argue respects local autonomy and existing community planning. The confrontation sets the stage for a high-stakes political battle, pitting the state's goal of solving a housing affordability crisis against the deeply entrenched principle of local control that defines suburban identity.

The Heart of the Conflict: State Mandates vs. Local Control

At the core of the dispute is the BUILD Act, Governor Pritzker’s answer to what his administration views as a critical shortage of affordable housing. While the final text is subject to legislative negotiation, the act’s framework aims to streamline development and override certain local zoning ordinances that the state sees as barriers. Proposals under discussion reportedly include measures to permit multi-family housing in areas currently zoned exclusively for single-family homes, reduce minimum lot sizes, and mandate higher-density development near transit hubs—reforms designed to accelerate construction and diversify housing stock.

The Governor's office and supporters of the bill, including housing advocacy groups and developers, argue that such measures are essential for economic growth, equity, and affordability. They contend that decades of restrictive local zoning have limited supply, driven up prices, and perpetuated patterns of economic and racial segregation. By creating a more uniform, permissive regulatory environment, they believe the state can unlock development and ensure all communities contribute to solving a regional problem.

However, the coalition of municipal leaders sees the BUILD Act not as a solution, but as a direct assault on their authority and a threat to their communities. "Residents overwhelmingly want individual communities to retain authority over planning and zoning decisions that impact neighborhoods, infrastructure, and quality of life," said David Pileski, DMMC President and Mayor of Roselle, summarizing the group’s core position.

This sentiment was echoed by leaders across the region, who framed the issue as one of state overreach. "Housing policy that increases local housing inventory should increase resident's investments not dilute it through pre-emption of local zoning controls," stated Donna Johnson, Libertyville Mayor and Northwest Municipal Conference President. Palos Hills Mayor Gerald Bennett, representing the Southwest Conference of Mayors, added a practical warning: "Local governments are responsible for maintaining community infrastructure. That cannot be separated from community development decision-making."

'Not So Fast': Residents Side with Local Leaders, Poll Shows

Bolstering the mayors' case is a recent county-wide poll conducted by the DuPage Mayors and Managers Conference (DMMC). The results paint a picture of a populace wary of state-imposed changes. According to the DMMC, more than 70 percent of DuPage County respondents believe zoning and land-use decisions should remain in the hands of local officials. Furthermore, over half of those polled stated that development in their communities is already happening at the right pace.

The poll also revealed residents' priorities, which appear to clash with the state's focus on increasing density. When asked about key concerns, respondents ranked affordability, taxes, and the overall cost of living significantly higher than the need for more housing density or accelerated expansion. Local leaders argue this data proves the BUILD Act is a solution in search of a problem, at least from their constituents' perspective.

"Today is about ensuring growth happens responsibly, with long-term planning that keeps our communities sustainable for future generations," said Wheaton Mayor and DMMC Vice President Phil Suess. His comments reflect a recurring theme: that municipalities are not against growth, but against uncontrolled growth dictated by the state.

To counter claims that they are obstructing development, the leaders pointed to their recent track record. They noted that over 6,100 multi-family units have been approved and built in DuPage County alone since 2020, with thousands more currently in the development pipeline. They present this as evidence of a balanced approach that allows for new housing while respecting existing community character—a strategy they claim aligns with resident preferences.

A National Debate Comes to Illinois

The clash in Illinois is not unique. It mirrors a contentious debate playing out in statehouses across the nation as governments grapple with severe housing shortages. In recent years, states like California, Oregon, and Massachusetts have passed landmark legislation to pre-empt local zoning in an effort to spur construction.

California’s SB 9 allows for duplexes on most single-family lots, while Oregon’s HB 2001 effectively eliminated single-family-only zoning in its larger cities. More recently, Massachusetts’ MBTA Communities Law mandated that towns near Boston rezone for multi-family housing near transit. These laws, championed by housing advocates as necessary interventions, have faced fierce legal and political challenges from local governments raising familiar concerns about infrastructure strain, loss of community character, and unfunded mandates.

The results from these pioneering states have been mixed. While some have seen a modest increase in housing permits, particularly for smaller units like Accessory Dwelling Units (ADUs), none have proven to be a silver bullet for the affordability crisis. The legislative battles have been bruising, and implementation has often been slow, mired in local resistance and legal ambiguity. This national context provides a cautionary tale for both sides of the Illinois debate, highlighting the immense difficulty of balancing state goals with local realities.

The Unanswered Questions of Infrastructure and Affordability

Beyond the philosophical debate over local control, municipal leaders are raising urgent, practical concerns about the potential real-world impacts of the BUILD Act. The most pressing issue is infrastructure. Mayors worry that state-mandated density will strain local schools, water systems, roads, and emergency services without providing the necessary funding to support the new population.

"Statewide mandates may look simple on paper, but local governments are the ones responsible for managing the real-world impacts," said Debby Sosine, Algonquin Village President, representing the McHenry County Council of Government. This sentiment underscores a fear that towns will be left to foot the bill for growth they were forced to accept.

While the BUILD Act is framed around improving affordability, local leaders question whether it will achieve that goal. They argue that simply increasing the supply of market-rate housing in high-cost suburban areas may not translate to lower prices for the residents who need it most. The challenge, as they see it, is creating genuinely affordable options in a way that is financially sustainable and integrated into the community.

As the press conference concluded, the mayors presented a unified message of conditional cooperation. "Responsible growth starts with listening to residents and ensuring development aligns with the long-term vision of local communities," said Barrington Village President Mike Moran. "We stand ready to work with legislators on balanced housing solutions that respect local communities, taxpayers, and long-term planning."

With both sides deeply entrenched, the path forward remains uncertain. The state government is pushing for a systemic overhaul to address a housing crisis it views as urgent, while a powerful bloc of local governments is mobilizing to defend its autonomy and what it sees as the will of its residents. The outcome of this standoff will likely shape the landscape of Illinois communities for decades to come.
