Would you vote yes on your local school district's bond referendum this November?

Several northern Illinois school districts have placed bond and tax referendums on the November 3, 2026 ballot, asking voters to fund repairs, new buildings and athletic facilities. Yorkville is returning with a scaled-back bond measure after voters rejected a similar proposal in spring 2026.

Why it matters

Districts cannot cover major projects from their operating budgets and reserves alone, so they are borrowing through bonds, which can raise property tax bills for homeowners in the affected districts. For Illinois families, the outcome will shape classroom space, school repairs and tax costs in the coming years.

Community Unit School District 300 is seeking $355,500,000 in bonds, Oswego District 308 is seeking $317 million, and St. Charles is seeking $282.5 million for repairs and a new athletic facility. Smaller districts are also on the ballot, including Waltham seeking $7,530,000 for a K-18 addition and Chadwick-Milledgeville seeking $12,370,000 for repairs and a gymnasium.

The players

Community Unit School District 300

An Algonquin-based district seeking $355,500,000 in bonds for classrooms and a career and technical education center.

Oswego Community Unit School District 308

A northern Illinois district seeking $317 million for major repairs and improvements.

St. Charles School District

A district seeking $282.5 million for repairs and a new athletic facility.

Yorkville School District

A district returning to voters with a scaled-back $159 million bond after a spring 2026 rejection.

Sandwich School District

A district seeking a higher limiting rate to raise about $19.6 million for facility repairs mandated by a state audit.

The details

Districts issue bonds to borrow money for projects too large for their budgets and reserves, then repay the debt over time through property taxes. Several districts say they plan to borrow new funds while paying off existing debts, which they argue keeps the overall tax impact lower. Sandwich's repairs are required by a state health and safety audit, and if its measure fails the district would still need to pay for the work through a loan that could cost more with interest. Yorkville is proposing $159 million to build an elementary school and a middle school after voters turned down a similar referendum this spring.

Spring 2026: Yorkville voters rejected a similar bond referendum, and the LaMoille advisory vote passed.
November 3, 2026: School referendums appear on the midterm ballot across northern Illinois.

The Home Front

School bond referendums are a recurring way Illinois districts finance capital work, and each one adds to the property tax levy that homeowners pay. Yorkville's return after a spring rejection shows how districts often revise and resubmit measures when voters push back on the first version.

If you live in one of the affected districts, check the November 3, 2026 ballot language and your county's estimate of how the measure would change your property tax bill. Homeowners in these districts should budget for a possible annual increase, which estimates place at roughly $100 to $650 per year depending on home value and district.

The takeaway

For Illinois families, school referendums are a direct lever on both classroom conditions and property tax costs, so reviewing your district's ballot question before November 3 is worthwhile. Keep your annual tax statement on file so you can compare any referendum's estimated increase against what you actually pay.

What happens next

Voters in the affected northern Illinois districts will decide these referendums on November 3, 2026, and the results will determine whether projects proceed and how property tax bills change.
