The Lake County Board voted unanimously on September 8 to impose an eight-month moratorium on data center applications and development in unincorporated areas of the county, freezing any potential proposals until May 11, 2027.
The pause covers a jurisdiction that has not yet received a single data center application. It exists to buy planning time before one arrives.
The measure can be extended by an additional four months if county staff need more time to draft regulations, and it will end early if the board adopts formal rules before the deadline, according to the Daily Herald’s coverage of the vote.
What the moratorium actually does
The freeze applies only to unincorporated Lake County — the land outside the boundaries of the county’s municipalities. Cities and villages inside the county retain their own zoning authority and are not bound by the ban.
During the eight months, county planning staff will draft definitions, zoning classifications, performance standards, review procedures, and possibly “community benefit” agreement templates for data center projects. The intent, county officials say, is to produce a regulatory package that municipalities across Lake County can adopt or adapt when proposals reach their desks.
Eric Waggoner, the county’s director of planning, building and development, told the Chicago Tribune that staff plan to synthesize lessons from communities around the country into local guidelines, and will track the progress of the state-level POWER Act — Protecting Our Water, Energy, and Ratepayers Act — during the review, as reported in the Tribune’s preview of the vote.
The county has been under a 120-day administrative deferral of data center applications since June. That deferral was set to end October 7. Tuesday’s vote was scheduled deliberately as the last full board meeting before that expiration.
How Lake County got here
The question first surfaced at a county committee meeting in December 2025, when board member Paul Frank asked staff how data centers could be regulated and, in his own words later, found the answers unsatisfactory. In June, the board authorized the process to pursue a moratorium.
That process included a public hearing before the advisory Zoning Board of Appeals and an online comment window. More than 1,300 public comments were entered into the record, according to Shaw Local’s account of the county’s process.
The public temperature around the topic has been high enough that a separate public meeting in Grayslake about a proposed data center was canceled in August over safety concerns tied to online comments, according to earlier Tribune reporting. That cancellation happened weeks before the county board’s vote and helps explain the volume of comments that landed in the record.
Marah Altenberg, chair of the board’s Planning, Building, Zoning and Environmental Committee, told the Tribune data centers are “probably the number one issue people in America are talking about now.” Her committee had recommended the moratorium unanimously the week before.
What residents in unincorporated areas gain, and what developers lose
For residents of unincorporated Lake County — the townships and rural fringes outside municipal borders — the immediate effect is that no data center can be sited on their land for at least eight months, regardless of zoning that might otherwise allow one. Concerns raised nationally about hyperscale facilities — grid load, water draw for cooling, truck traffic during construction, low permanent employment relative to footprint — are deferred rather than resolved.
For developers and site scouts, the practical effect is that unincorporated Lake County comes off the map through May 2027 at the earliest. Any company shopping for northern Illinois acreage will need to look inside municipal boundaries, where local councils still control their own zoning.
That split matters. Board members framed the county’s role as gathering the most information possible before rules are set. The regulatory template the county produces may end up shaping what happens inside village limits too, if municipalities choose to adopt it.
The Illinois Clean Jobs Coalition praised the decision and called on the General Assembly to enact statewide data center regulation this fall, according to a Center Square roundup carried by Yahoo News. Several county board members said much the same during the vote — that the issue is broader than any single county and needs Springfield to act.
Part of a wider pattern
Lake County joins a growing list of local governments that have used the moratorium as their first regulatory tool against a data center pipeline that outpaces existing zoning codes. Linn County, Iowa recently froze new data center approvals in unincorporated land for 18 months, and Lakeland, Florida paused a 600,000-square-foot, 100-megawatt project to work out who pays for the grid and water a hyperscale tenant requires.
The framing that recurs in these votes — from a board member quoted by Lake and McHenry County Scanner as saying “we choose our citizens” — is that local governments have found themselves reacting to a national build-out designed around speed. A moratorium is the one tool that reliably slows the clock without requiring a fully drafted ordinance on day one.
The trade-off is transparent. Counties give up the option to say yes for a defined window in exchange for the time to write rules that could otherwise be written in the middle of an active application, under pressure.
Lake County has not received an application. That is the point. The board acted before the first proposal, not after.
What happens between now and May depends on staff work most residents will never see — zoning definitions, performance standards, water and energy thresholds, review procedures. It also depends on Springfield. If the POWER Act moves this fall, the county’s rules will be written against a state framework. If it does not, Lake County’s template may end up filling the gap for its own municipalities.
Either way, the eight months belong to the planners now.
