Two condo listings go up in Darien the same week. Both quote a monthly association fee in the same ballpark, both show a recent kitchen refresh, both look like a clean move-in. One sits in a building from the late 1960s. The other went up in the late 1980s. Nothing on the listing sheet flags the twenty-year gap, and nothing legally has to. That gap is where the real financial exposure of buying a Darien condo actually lives, and it has almost nothing to do with the fee printed at the top of the page.
I've walked buyers through enough of these transactions to know the fee is the number people fixate on and the number that tells them the least. What actually predicts whether you'll be writing a four-figure check to your association in year three is the building's age, whether its board has ever paid for a reserve study, and how much the state of Illinois currently requires anyone to tell you about either one. Right now, the honest answer is: not as much as you'd assume.
The Fee on the Listing Sheet Is a Coincidence of Timing, Not a Risk Score
Darien's condo stock spans roughly a quarter century of construction, and the fee ranges don't line up neatly with age the way you'd expect. Brookdale at Darien, built between 1967 and 1978, currently carries HOA fees between $350 and $485 a month. Darien Lake, a townhouse and condo community built from 1974 to 1987, runs $250 to $436. Woodlands, built between 1986 and 1990 and mixing condos, townhomes, and single-family product, spans a much wider $142 to $447.
| Community | Built | Current HOA fee range |
|---|---|---|
| Brookdale at Darien | 1967–1978 | $350–$485/month |
| Darien Lake | 1974–1987 | $250–$436/month |
| Woodlands | 1986–1990 | $142–$447/month |
Notice that Woodlands, the newest of the three, has both the lowest fee floor and one of the higher ceilings in the group. A buyer scanning listings by fee alone could easily pick the oldest building because its middle-of-range fee looks tamer than a newer one at the top of its band. The fee reflects what a board decided to charge this year. It says nothing about what that board has set aside for the roof, the parking lot, or the boiler that's been running since the Ford administration.
Other well-known Darien condo clusters, Farmingdale Terrace among them, add even more spread to that picture. The point isn't that older is automatically worse. It's that the fee alone can't tell you which situation you're walking into, and Illinois law puts the burden of finding out on the buyer, not the seller.
What Section 22.1 Actually Requires, and What It Doesn't
Illinois does give buyers a tool here. Section 22.1 of the Illinois Condominium Property Act requires a seller, upon a buyer's demand, to obtain from the board and make available a specific packet: the declaration and bylaws, a statement of any liens or unpaid assessments on the unit, a statement of any capital expenditures the association anticipates in the current or next two fiscal years, and a statement of the status and amount of the reserve fund. The statute is explicit that the principal officer of the association "shall furnish the above information when requested to do so in writing and within 10 business days of the request."
That last detail matters more than it sounds. The disclosure isn't automatic. A buyer, or more realistically a buyer's attorney, has to demand it in writing. Skip that step and you've waived a protection the state built specifically for this transaction. In 2022, Illinois also capped what an association can charge to produce this packet at $375, adjustable for inflation, closing off a practice where some management companies had turned the disclosure fee itself into a minor profit center.
The capital expenditure statement is the line worth reading twice. It's supposed to flag whether the board is planning a major project in the next two fiscal years, which is exactly the window that would catch a new owner holding the bag. In practice, attorneys who work with these disclosures regularly note that boards sitting on an unresolved decision, quotes obtained but no vote taken, no firm timetable, can legitimately leave that line vague. A "we're evaluating options" answer is not a violation. It's also not the same as "nothing planned."
The Vote Isn't the Safeguard Most Buyers Assume It Is
Here's the part that surprises people who've owned a single-family home and are buying into a condo for the first time. A board does not need owner approval to levy a special assessment in Illinois. Under Section 18(a)(8) of the Condominium Property Act, the board can adopt one on its own, provided the resulting total of all regular and special assessments for the year doesn't exceed 115 percent of what owners paid the year before.
If it does cross that threshold, owners holding at least 20 percent of the association's votes can file a written petition, and recent guidance puts that window at 21 days from the board's action. Even then, the assessment isn't automatically rejected. The board has to call a membership meeting within 30 days, and at that meeting a majority of all unit owners, not just the ones who show up, has to vote it down. Absences and abstentions function as votes in the board's favor. In a building where turnout is thin, that's a high bar to clear.
The upshot: a board can push through a meaningful assessment with zero owner votes cast in favor of it, as long as the math stays under 115 percent and nobody organizes a petition fast enough. That's not a loophole. It's how the statute is written. It's also exactly why the capital expenditure line in your 22.1 packet deserves more scrutiny than a quick skim.
Illinois Still Doesn't Require a Reserve Study
The tool that would make all of this more predictable, a reserve study, isn't mandatory in Illinois yet. The Condominium Property Act requires boards to budget "reasonable reserves for capital expenditures and deferred maintenance," but it doesn't require a professional study on any set schedule, and neither does the Common Interest Community Association Act that governs most non-condo HOAs. An association can be entirely compliant with state law while running on a reserve estimate nobody has updated in over a decade.
Legislators have been trying to close that gap. A bill in Springfield, tracked as HB2563 and its Senate companion SB3401, would require common interest associations to conduct a reserve study every five years and make it available to prospective buyers on request. By mid-April 2026 it had been engrossed, and by mid-May it had picked up an additional co-sponsor along with a House Rules Committee hearing on the calendar. What happened at that hearing and where the bill stands as of today isn't something I can confirm here, so treat a mandatory reserve study as a proposal still working its way through the legislature rather than a settled requirement. Ask your attorney to check its current status before you assume it applies. What's certain right now is that no statewide reserve study requirement is in force. If you're buying into a building from the 1970s or 1980s, the existence of a recent reserve study is something you have to ask for. It is not something the seller is obligated to hand you.
What to Actually Ask Before You Waive Attorney Review
If you're under contract on a Darien condo, or about to be, these are the specific things worth putting in writing to the seller's attorney or the association's management company before your attorney review period closes.
- Request the full Section 22.1 packet in writing immediately, not casually. The clock on the seller's response only starts once the demand is on paper.
- Ask directly whether a reserve study has ever been performed, and if so, how recent it is. Silence or a vague answer is itself useful information.
- Read the capital expenditure statement for what it doesn't say as much as what it does. "No expenditures anticipated" and "the board hasn't finalized a decision yet" are not the same sentence, even when they end up looking similar on the form.
- Ask whether the association's total assessments have approached the 115 percent threshold in the past two years, and whether any owner petition was ever filed. A near miss last year is a pattern worth knowing about before you close.
- Confirm the fee cap. If the association or its management company quotes you more than $375 to produce the disclosure, that's worth flagging to your attorney.
None of this turns a Darien condo into a bad idea. Plenty of these buildings are well run, with boards that fund reserves properly and communicate clearly. The point is that you can't tell which kind you're buying into from the listing sheet, and the state currently leaves that homework to you.
A Few Common Questions
Does every condo resale in Illinois require a 22.1 disclosure? Section 22.1 applies to resales by an owner other than the developer, and it's triggered once a buyer demands it in writing. It runs alongside, not in place of, the standard Illinois Residential Real Property Disclosure Act that applies to all home sales.
Can a board really pass a special assessment without any owner vote? Yes, as long as the total assessments for the year stay under 115 percent of the prior year's total. Above that line, owners can petition for a vote, but the assessment still stands unless a majority of all owners, not just those who attend the meeting, votes to reject it.
Is a reserve study legally required in Illinois right now? No. Current law requires boards to budget reasonable reserves but does not mandate a professional study on any schedule. Legislation that would change that has been moving through Springfield, but confirm its current status before assuming it's in effect.
Buying into an established Darien association shouldn't feel like a guessing game, and it doesn't have to be one if you know which questions to ask before the attorney review clock runs out.
