How District 86 Can Borrow $82 Million Without a Referendum, and Where It Shows Up on a Hinsdale Tax Bill

Every Hinsdale listing sheet has a tax figure near the bottom. Buyers plug it into a mortgage calculator, add insurance, and treat the total as the cost of owning the house. That figure comes from bills issued before Hinsdale Township High School District 86 proposed $82 million in new borrowing, which the district plans to sell without putting a question on the ballot.

The plan has two pieces, a $46 million working cash bond issue and a $36 million life-safety bond issue, according to The Hinsdalean. The district will also put $21 million from its operating fund toward facilities over the next three years, which brings about $100 million to Hinsdale Central and Hinsdale South. The board is expected to take up the sale on November 17, five days after this post goes up.

The district's own example, line by line

The district's financial advisors put the cost in terms of one sample home. Here is that example as The Hinsdalean reported it:

Together, the two bond sales would produce about $120 million in debt service over 20 years.

A $1.14 million house is a modest example for Hinsdale itself. MRED's Local Market Update for September 2026 shows a median detached sale price in Hinsdale of $1,857,500 on 20 closings. Attached homes had a median of $792,500 on 4 closings, with data current as of October 14, 2026. District 86 covers more than the village. Its example home sits above the village's attached median and well below the detached median, so for a typical single-family house in Hinsdale, $166 is the low end of the published range. The district has published an estimate for just this one home value, so the cost at other prices is a question to put to the district rather than something to work out on a calculator.

The 1994 number that lets this skip the ballot

When residents last paid for big school projects, they voted on them. Superintendent Chip Pettit, who joined the district in June, told the board that one thing he hears again and again is that voters passed a $139 million referendum in 2019. This time the structure is different.

Illinois tax-cap law sets up a "debt service extension base" for capped taxing districts. Under 35 ILCS 200/18-185, the base starts from the district's 1994 levy-year extension for principal and interest on bonds issued without a referendum. It grows each year by the lesser of 5% or the increase in the consumer price index. Raising the base itself takes a referendum, according to 35 ILCS 200/18-212. Borrowing inside the existing base does not.

The Hinsdalean explained the district's position in plain terms. Tax-cap law lets D86 spend a set amount each year on bond and interest costs, equal to what it spent in 1994 adjusted for inflation. If new debt doesn't push repayments past that amount, no referendum is required.

Under that rule, the test for D86's plan is whether the new repayment schedule fits under a ceiling set three decades ago. That ceiling rises with inflation each year, and so does the room for non-referendum borrowing.

The 30-day brake, and why it only touched half the package

The working cash bonds came with one check. 105 ILCS 5/20-7 gives residents 30 days after the district publishes its notice to file a petition. If at least 10% of the district's registered voters sign, the bonds can't be issued until voters approve them at a regularly scheduled election.

District 86 ran that sequence this fall:

1. September 29. The board held a public hearing on its intent to sell working cash bonds and approved a resolution of intent.
2. October 1. The notice of intent was published, which started the 30-day clock.
3. November 2. The petition window closed.
4. November 17. The board is expected to consider parameter resolutions authorizing the sale.
5. November 23. Bonds could be sold as early as this date, with the board able to close the sale as late as February, its levy-filing deadline.

The life-safety bonds go through a different gate. 105 ILCS 5/17-2.11 lets districts issue them for specified safety purposes. They must mature within 20 years and be repaid through a direct annual property-tax levy. District 86's list of life-safety amendments has to be approved by the Illinois State Board of Education before those bonds can be issued. Once they are, the district has three years to do the work and can spend the proceeds only on approved projects. Brad Paulsen of Wight and Co., the district's architect, told the board the goal was to have state approval "in some fashion" by November 17.

What the money is pointed at

The project list isn't final, but the board has agreed on its priorities. The biggest single item is a new heating plant at Hinsdale Central that converts the building from steam to hot water. It's a three-summer project estimated at $16.7 million. Renovated athletic fields at both schools, a larger outdoor commons at Hinsdale South, updated science and culinary arts labs, and modernized wellness spaces and locker rooms fill out the list.

Work planned at Central for summer 2027 includes phase one of the heating plant, renovation of two locker rooms, a new air handling unit for the gym, and new athletic field lighting. Pettit described the buildings' age to the board this way, as The Hinsdalean reported:

"Even heavy renovation, at best, is a 20-year solution."

The original sections of Central and South are 76 and 61 years old. The repayment schedule runs 20 years, about as long as Pettit expects heavy renovation to last.

The rate argument, and the condition on the sale

Bob Lewis of PTMA Financial Solutions, the district's financial advisor, told the board that D86 would still have one of the lowest tax rates among comparable districts even after the increase. He put D86's rate at $1.56 and Stevenson's at $2.97. That comparison comes from the district's own advisor, made in support of the plan.

Lewis also tied the sale to the bond market. "If November is like it is now, we may not want to sell the bonds," he said, according to The Hinsdalean, pointing to unstable market conditions at the time. The plan has also grown since the summer. Patch reported that the August discussion involved $39 million in life-safety projects, and that the district's estimate back then was an $83 first-year increase on a $570,000 median-value home. The $166 figure is the one tied to the current $82 million package.

What this means for a Hinsdale purchase this winter

If you're writing an offer in November or December, the seller's most recent tax bill reflects the debt District 86 carried before this sale. The new debt-service levy only shows up once the bonds are sold and levied. In the district's example, that line then climbs about $20 a year, every year, on top of whatever reassessment does to the rest of the bill. If you're comparing a Hinsdale house against one in another district, the useful number is the projected bill, not last year's.

For sellers, the same timing works the other way. A buyer who has read the November 17 agenda may price in the higher debt line even though your bill doesn't show it yet.

FAQ

Does the $82 million need voter approval? Only if a qualifying petition was filed. The working cash bonds go to a referendum if 10% or more of registered voters signed a petition within the window that closed November 2. If no petition was filed, the board planned to vote on the sale November 17. The life-safety bonds need state approval instead of voter approval.

Is the sale final? No. The board is scheduled to consider authorizing it on November 17, and the bonds could be sold as early as November 23. The board has until February to close, and its financial advisor said the district might hold off if market conditions are poor.

How long will the new debt stay on tax bills? The district projects about $120 million in debt service over 20 years. State law caps both kinds of bonds at a 20-year maturity.
