You find a condo you love, then see the monthly assessment and wonder what it does to your budget. In Chicago, that number can range from $250 a month in a Lincoln Park walk-up to well over $1,200 in a Gold Coast tower — and the difference isn't just amenities. It's building age, mechanical systems, staffing, and how seriously the association has funded its reserves.
This guide covers what assessments cover, how they're calculated, what healthy reserves actually look like, and what to review before you write an offer.
A condo assessment — also called an HOA fee or monthly dues — is your mandatory share of the building's operating costs plus a contribution to reserves. It is not optional, and it is not negotiable at closing.
The calculation is a two-step process. First, the board adopts an annual budget covering operating expenses and reserve contributions. Second, that total is divided among units according to each unit's percentage of ownership in the common elements, as stated in the declaration:
Monthly assessment = (annual budget × unit's percentage interest) ÷ 12
This is why a larger unit pays more even when it uses the same elevator and lobby. Your percentage interest is fixed in the declaration and doesn't change with market value or renovations.
Illinois codifies this in 765 ILCS 605/9(a), which requires every unit owner to pay a proportionate share of common expenses in the same ratio as their percentage of ownership in the common elements.
Section 18(a)(8) gives owners a check on runaway increases. If an adopted budget or separate assessment would push total assessments for the current fiscal year above 115% of the prior year's total, owners holding 20% of the association's votes can petition the board within 21 days. The board must then call an owner meeting within 30 days to vote on it.
Typically included | Typically excluded |
|---|---|
Common-area utilities (water, sewer, trash) | In-unit electricity |
Master insurance for common elements and liability | HO-6 unit insurance |
Routine maintenance and janitorial (lobby, elevators, roof, grounds) | In-unit maintenance and appliances |
Reserve fund contributions | Deeded or separately billed parking and storage |
Management, legal, and administrative fees | Special assessments |
Building staff (doorman, concierge, porters) in serviced buildings | Cable and internet, unless bulk-contracted |
One Chicago pattern is worth knowing before you compare two listings side by side. Vintage buildings — pre-1970s courtyards, walk-ups, and early high-rises — run radiator heat and domestic hot water off a central boiler. Because individual radiators aren't metered, heat and hot water are almost always included in the assessment. A $400 assessment in a 1920s three-flat may cover more than a $500 assessment in a 2015 building.
Buildings from the 1980s forward typically give each unit its own HVAC and water heater, metered directly to the owner. Heat and hot water are excluded, and you pay ComEd or Peoples Gas separately.
Related note for anyone planning to rent the unit out: in buildings where heat is a shared service, the Chicago Heating Ordinance (Mun. Code Ch. 13-196) requires minimum interior temperatures from September 15 through June 1 — 68°F daytime, 66°F overnight — and that obligation falls on the board. If you rent under the RLTO, you must disclose in writing who pays each utility before the lease is signed.
Always get inclusions in writing. Verbal summaries from listing agents are wrong often enough to matter.
Assessment-per-square-foot is the only fair way to compare buildings. A $700 fee on 1,400 square feet is cheap; the same fee on 700 square feet is not.
Sampled from active MLS listings, August 2026, across Lincoln Park, Lakeview, Logan Square, River North, Streeterville, West Loop, and South Loop.
Building type | Range ($/sq ft/mo) | Median | Representative areas |
|---|---|---|---|
Vintage walk-up (3–4 stories, pre-1940s, 3–12 units) | $0.25 – $0.45 | $0.33 | Lakeview, Lincoln Park, Logan Square, Ravenswood |
Mid-rise / loft (5–12 stories, 20–80 units) | $0.40 – $0.65 | $0.52 | West Loop, South Loop, Bucktown, River North |
Full-amenity tower (20+ stories, 100+ units, 1960s–2000s) | $0.70 – $1.15 | $0.88 | Streeterville, Gold Coast, River North, South Loop |
Luxury new construction (2018–2026) | $0.85 – $1.40+ | $1.10 | Fulton Market, West Loop, Gold Coast, Lincoln Park |
On a 1,000-square-foot unit, that's roughly $330 a month in a walk-up, $520 in a loft, $880 in a full-amenity tower, and $1,100 or more in new construction.
This is the question most buyers skip and most regret skipping. The reserve fund is the association's savings account for major repairs — roof, elevators, façade, boilers, risers. When it's underfunded, the shortfall arrives as a special assessment with your name on it.
The industry benchmark is Percent Funded, defined by the Community Associations Institute's National Reserve Study Standards:
Percent Funded = (actual reserve balance ÷ fully funded balance) × 100
The "fully funded balance" is what the association should have on hand given the accumulated wear on its components. CAI sorts the result into three bands:
Band | Percent funded | What it means |
|---|---|---|
Weak | 0% – 29% | High exposure to unfunded capital failures and abrupt special assessments. Roughly a third of associations sit here. |
Fair | 30% – 69% | Moderate risk. Vulnerable to unexpected component failure or material cost inflation. Needs structured annual increases. |
Strong | 70% – 100%+ | Low risk. Resilient to surprise projects and protective of resale value. |
A dollar balance alone tells you nothing. A $400,000 reserve is strong for a 20-unit building and dangerously thin for a 200-unit high-rise facing a façade cycle. Ask for the percent funded, not the balance.
765 ILCS 605/9(c)(2) sets a reasonable reserves standard rather than a fixed dollar or percentage threshold. Boards must maintain reasonable reserves for capital expenditures and deferred maintenance, and in setting the amount are required to consider: repair and replacement costs and remaining useful life of the common elements; anticipated return on invested association funds; any independent professional reserve study; the financial impact on owners of the assessment increases needed to fund reserves; and the association's ability to obtain financing.
Illinois also allows associations to waive the statutory reserve requirement, which is the part buyers should watch for. If the declaration doesn't independently require reserves, owners may waive the requirement in whole or in part by a two-thirds vote of the total voting interest. A waiving association must disclose the waiver in its financial statements and flag it in bold print on every Section 22.1 disclosure it gives to prospective buyers — and the waiver shields the board and manager from liability for inadequate reserves.
If you see that bold-print disclosure, treat it as a pricing issue, not a footnote.
A reserve study is a long-term capital plan prepared by an engineer or credentialed Reserve Specialist. It has two halves: a physical analysis inventorying every major component and its remaining useful life, and a financial analysis comparing the current balance against the target and mapping out contribution rates over 20 to 30 years.
Studies come in three levels:
Building type | Level I | Level II | Level III |
|---|---|---|---|
Small vintage walk-up (3–12 units, no elevator) | $1,500 – $2,500 | $1,000 – $1,600 | $600 – $1,000 |
Mid-rise / loft (15–60 units, 1–2 elevators) | $3,000 – $5,000 | $2,000 – $3,200 | $1,200 – $1,800 |
High-rise tower (100–300+ units, central HVAC) | $6,500 – $12,000+ | $4,000 – $7,500 | $2,500 – $4,000 |
High-rise pricing reflects specialized engineering for Chicago Exterior Wall Ordinance compliance, central plant systems, and parking structures. Firms active in Chicagoland include Reserve Advisors, Criterium Engineers, and MillerDodson Associates.
The practical takeaway for buyers: a full study costs a fraction of one special assessment. An association that won't spend $4,000 on a Level I study is telling you something about how it handles $400,000 problems.
Special assessments are one-time charges for capital work that reserves and the operating budget don't cover. Under Illinois law the board holds the authority to adopt them at a properly noticed open meeting. Owners do not vote to approve a routine special assessment unless the declaration requires it or the 115% threshold is triggered.
Mechanism | Threshold and deadline |
|---|---|
Trigger | Total regular + separate assessments for the fiscal year exceed 115% of the prior year's total |
Petition | Signed by owners holding at least 20% of association votes |
Filing deadline | Within 21 days of the board's adopting action |
Meeting | Board must convene owners within 30 days of a valid petition |
Rejection | Requires a majority of total votes — absent that, the assessment stands |
Two wrinkles matter. Separate assessments for additions and alterations to common elements that weren't in the adopted budget are subject to owner petition rules under §18(a)(8)(v) regardless of the 115% math. And assessments for emergencies or repairs mandated by law are exempt from the threshold, the petition process, and any rejection vote. "Emergency" means immediate danger to the structural integrity of the common elements or to owners' life, health, safety, or property. If a board acts under that authority, it must notify owners of the event within seven business days and describe the actions taken within seven days.
Regular monthly assessments are never insurable. Special assessments sometimes are — but only through a loss assessment endorsement on your HO-6 policy, and only under narrow conditions.
Covered: the assessment must stem from a peril covered under your policy or the master policy, or from a common-area liability claim. The classic triggers are fire or storm damage to shared areas exceeding the master policy limit, a liability judgment against the association exceeding its general liability coverage, or a board levying an assessment to cover the master policy's property deductible after a major covered loss.
Not covered: anything rooted in deferred maintenance or operations. Roof replacement due to age, tuckpointing, riser replacement, elevator modernization, code upgrades, unfunded reserves, operating deficits, or flood and earthquake damage without a specific endorsement.
Limits: off-the-shelf Illinois HO-6 policies typically carry a default loss assessment limit of just $1,000. Single-event assessments for master policy deductibles or fire repairs routinely run $10,000 to $50,000 per unit. Brokers generally recommend endorsing up to $10,000–$25,000, or matching the association's master deductible, at a premium cost of roughly $10 to $30 per year. It is the cheapest meaningful protection in a condo purchase, and most buyers never ask about it.
Illinois gives you a statutory floor. 765 ILCS 605/22.1 requires the seller to obtain a disclosure packet from the board, which must furnish it within 10 business days of a written request.
The statutory items include the declaration, bylaws, and current rules; a statement of liens and the unit's unpaid assessments; capital expenditures anticipated in the current or succeeding two fiscal years; the status and amount of replacement reserve funds, including any portion earmarked for specific projects; the association's statement of financial condition for the most recent fiscal year available; the status of pending suits or judgments naming the association; a statement of insurance coverage provided to owners; a good-faith statement that prior alterations to the unit comply with the condominium instruments; and the name and address of the officer or agent authorized to receive notices.
Associations may charge up to roughly $375 for the packet (CPI-adjusted annually), plus about $100 for 72-hour turnaround.
The statutory list is a floor, not a due diligence plan. During attorney review, also request:
There are two paths. Full project approval puts the whole association on HUD's approved list, valid three years before recertification. It's common in large lakefront high-rises and mid-2000s mid-rises; smaller vintage buildings often let it lapse because nobody wants the paperwork.
If the building isn't approved, Single-Unit Approval may still work, subject to project-level tests: at least 5 units in the development; no more than 10% of units FHA-insured (max 2 units in 5–9 unit buildings); at least 50% owner-occupancy; commercial space under 35% of floor area; no more than 15% of units 60+ days delinquent on assessments; and no single entity owning more than 10% of units (max 1 unit in 5–20 unit buildings).
Check status directly at HUD's Condominium Project Approval lookup, filtering by state, county, and city or ZIP. "Expired," "Withdrawn," or absent means an SUA review through a Direct Endorsement lender.
Fannie Mae and Freddie Mac review the project, not just you. On special assessments, the lender must document the purpose, total approved amount, and repayment schedule, and confirm the assessment doesn't compromise the association's stability or the units' marketability — even when the seller pays it off at closing. Critically, if a special assessment funds critical repairs, structural defects, or safety hazards, the project is ineligible until those repairs are fully complete and documented.
Post-Surfside standards added a structural screen. Projects are non-warrantable with active evacuation orders or structural violation notices, unaddressed structural or mechanical deficiencies (load-bearing, foundation, balcony, façade, elevator), or unfunded repairs exceeding $10,000 per unit scheduled within 12 months. Lenders must review all structural and mechanical inspection reports from the past three years, including Chicago Critical Exterior Wall Inspection reports, and boards must complete a structural questionnaire addendum.
The practical consequence: in an older Chicago high-rise, a pending façade project can make the building unfinanceable for months. Confirm project eligibility before you go under contract, not after.
For high-rise condos, the façade is the single largest capital exposure that exists. Under Municipal Code §§14A-6-603.2–603.4, buildings over 80 feet — roughly six stories and up — face mandatory exterior wall inspection cycles.
A hands-on Critical Examination, using swing-stage scaffolding drops, is required every 4, 8, or 12 years depending on construction materials and category classification. Visual short-form inspections must be filed every 2 years in between.
The inspection alone runs $30,000 to $100,000+ for a 20-to-40-story tower, before any repair. When the examination finds concrete spalling, failing terra cotta, or corroded ties, remediation routinely costs $1,000,000 to $8,000,000+ — which across a 200-unit building means $15,000 to $45,000+ per unit in special assessments.
Original single-pane and early insulated glazing systems in that generation of high-rises are now at end of life. Full replacement runs $25,000 to $60,000+ per unit, or $5 million to $18 million+ for a 200-unit tower, and requires phased staging with swing-stage access, interior unit entry, drywall rebuilding, and HVAC re-sealing.
Twenty-four-hour door staff is frequently the largest single line in a building's operating budget, running roughly $200,000 to $350,000 annually in payroll and benefits. Pools, garage decks, large fitness facilities, and high elevator counts multiply ongoing maintenance relative to a walk-up.
Chicago's freeze-thaw cycles do the rest. Water enters masonry cracks, freezes, expands, and spalls concrete; heavy snow loads and high wind shear at elevation shorten the life of roofs and sealants well below what the same materials would deliver in a milder climate.
Two 1,000-square-foot condos, same price, same loan, very different carrying cost.
Assumptions: $400,000 purchase, 20% down, $320,000 loan at 6.67% fixed over 30 years. Cook County effective rate ~1.85% of market value (10% assessment level × ~3.0 equalizer × ~6.7% composite rate).
Component | Vintage walk-up (Lincoln Park) | Full-amenity high-rise (River North) |
|---|---|---|
Principal & interest | $2,059 | $2,059 |
Property taxes | $617 | $617 |
Condo assessment | $330 ($0.33/sq ft) | $880 ($0.88/sq ft) |
HO-6 insurance | $65 | $80 |
In-unit utilities | $120 (electric + gas) | $60 (electric only) |
Total | $3,191 | $3,696 |
The differential is $505 a month — 15.8% — and it isn't the whole story. In the high-rise, assessments are about 24% of total carrying cost versus roughly 10% in the walk-up. Because lenders count the full assessment in your debt-to-income ratio, an extra $550 a month in fees cuts your borrowing capacity by roughly $80,000 in principal.
That's the part buyers miss. A high assessment doesn't just raise your payment; it lowers your price ceiling.

Neighborhood | Median condo price | Median $/sq ft | Median assessment | Dominant stock and drivers |
|---|---|---|---|---|
River North | ~$480,000 | $433 | ~$550 – $750/mo | High-density 1990–2015 towers and timber lofts; 24/7 staff, decks, pools, garage maintenance |
Gold Coast | ~$650,000 | $396 | ~$700 – $1,100+/mo | Mid-century Lake Shore Drive towers and pre-war buildings; aging risers, elevators, curtain wall, high service levels |
Lincoln Park | ~$725,000 | $402 – $502 | ~$350 – $550/mo | Low- and mid-rise walk-ups and boutique conversions; little staffing, many self-managed 3-to-6 unit associations |
River North medians are held steady by large amenity buildings like Grand Ohio (211 W Ohio) and Grand Plaza (540 N State), while boutique properties on Illinois and Huron trade at $550–$700+ per square foot.
Gold Coast is bimodal. Carl Sandburg Village pulls median prices down with $200K–$400K entry-level units at moderate fees, while 1210 N Lake Shore Drive and 1555 N Dearborn carry assessments of $1,200 to $2,500+ on larger layouts. The neighborhood's older infrastructure is the reason its per-square-foot fees run highest in the city.
Lincoln Park has the lowest monthly assessments and the highest special assessment volatility. A $40,000 roof on a three-unit building is $13,000 per owner with no reserve cushion. Low fees in a small association are not the same as low risk. Exceptions along the park — 2626 N Lakeview, 2800 N Lake Shore Drive — behave like Gold Coast towers.
Cook County bills one year in arrears — the bill you pay in 2026 covers the 2025 tax year.
Installment | Basis | Timing |
|---|---|---|
First | Fixed at 55% of the prior year's total bill, no exemptions applied | Mailed late January/February, due March 1 (occasionally early April) |
Second | Updated assessed value, state equalizer, local rates, minus exemptions | Mailed summer/early fall, due August 1 – October 1 depending on state certification |
Chicago townships are reassessed on a three-year cycle. Following the 2024 reassessment, the next full city revaluation lands in 2027. In off-cycle years, individual units are only reassessed for new construction, structural alteration, or division.
If you're buying, that 2027 date matters: budget for a possible step-up rather than assuming the seller's current bill carries forward.
Owners get a 30-day window to appeal after the Assessor publishes the township roll, plus a second window at the Board of Review. Condo boards frequently hire tax counsel to file a single building-wide appeal based on recent in-building sales, which typically outperforms individual filings.
Second City Agents is a team of 12 brokers with deep roots across Chicago's neighborhoods and the western suburbs. Recognized as the no. 18 large team in Chicago by RealTrends in 2024, with nearly $90 million in closed 2025 sales, we handle first-time condo purchases, move-up buyers, and investment acquisitions across the city and beyond.
On condo purchases specifically, that means pulling the reserve study and reading it, calling the management office about the façade cycle, checking FHA status before you fall in love with a unit, and telling you when a low assessment is hiding a problem rather than reflecting a well-run building.
Contact Second City Agents to talk through the buildings on your shortlist — from the city to the suburbs.
How are monthly condo assessments determined? The board sets an annual budget covering operating costs and reserve contributions, then allocates it among units by percentage of ownership interest as defined in the declaration. Your monthly fee equals (annual budget × your percentage interest) ÷ 12. Illinois requires this proportional allocation under 765 ILCS 605/9(a).
How much should a condo association have in reserves? There's no single dollar figure — the benchmark is percent funded, meaning actual reserves divided by the fully funded balance. Under CAI standards, 0–29% is weak with high special assessment risk, 30–69% is fair, and 70%+ is strong. Illinois law (765 ILCS 605/9(c)) requires "reasonable reserves" and lists factors boards must weigh, but sets no fixed threshold, and associations may waive the requirement by a two-thirds owner vote.
What is a condo reserve study and how much does it cost? It's a professional capital plan combining a physical inventory of major components with a 20-to-30-year funding model. In Chicago, a full Level I study runs $1,500–$2,500 for a small walk-up, $3,000–$5,000 for a mid-rise, and $6,500–$12,000+ for a high-rise. Site-visit updates cost 60–70% of that and are recommended every 3 to 5 years.
Does condo insurance cover special assessments? Only through a loss assessment endorsement on your HO-6 policy, and only when the assessment stems from a covered peril or a common-area liability claim — including assessments levied to fund the master policy deductible after a covered loss. It never covers deferred maintenance, code upgrades, or operating deficits. Default limits are often just $1,000; raising coverage to $10,000–$25,000 typically costs $10–$30 per year.
What happens if a special assessment is announced while I'm under contract? Request the board's notice, the approved amount, and the payment schedule, then negotiate who pays. Your lender will require disclosure and may treat it as additional monthly debt, require payoff or escrow at closing, or — if the assessment funds critical or structural repairs — declare the project ineligible until the work is complete.
Are utilities included in Chicago condo assessments? It depends on building age. Vintage buildings with central boilers almost always include heat and hot water because individual units aren't metered. Buildings from the 1980s forward typically meter HVAC and hot water to each unit, so those costs fall to the owner. Common-area water, sewer, and trash are usually included in both cases. Confirm in writing.
