District 88 has placed a bond referendum on the Nov. 3, 2026, ballot to address facility needs at Addison Trail and Willowbrook high schools.
The question requests permission to authorize the issuance of $118 million in referendum bonds, without a net tax rate increase. Facility improvements include safety and security upgrades and improvements to infrastructure, ADA accessibility and Career and Technical Education (CTE) spaces.
The bond referendum would fund the updates listed above without a net tax rate increase. This is possible because District 88 has existing referendum debt that will be paid off after levy year 2026, and the district has limited the proposal to the highest-priority needs.

If the referendum were approved, the district plans to provide regular updates, including funding and construction details, through its website, social media and other communication channels to ensure transparency and accountability.
The Board will address projects as part of the annual budget allocation for facilities maintenance. In recent years, that allocation has been approximately $1.5M-$2M; this allocation would be reviewed and potentially adjusted based on existing revenues and costs. Priority would be placed on emergency needs and items that would be necessary to keep the facilities operational.
The price points listed in the proposed projects list are estimates based on the market conditions at the time the list was created. If the referendum is approved, the Board will move forward with actual detailed project plans. Due to the cost of the proposed projects, they will need to be formally bid. Bids are awarded to the lowest responsive and responsible bidder. If the costs exceed the revenue amount, the Board may consider reducing the scopes of one or more of the projects and/or allocating funds from the operating budget to address the difference. Alternatively, if pricing is more in the favor of the district, the Board could address more of the identified projects.
