HOA Management in Illinois: Condominium & Common Interest Community Law Guide 2026
Illinois splits community association law into two statutes: the Illinois Condominium Property Act (765 ILCS 605) governs every condo association, while the Illinois Common Interest Community Association Act (765 ILCS 160) governs many non-condo HOAs — townhomes and single-family communities — though smaller associations may be exempt.
Board meetings require 48 hours' notice. Assessment liens attach automatically on default. Unlike many states, Illinois currently has no statewide mandatory reserve study requirement. IgeraFincas handles resident Q&A 24/7, citing the exact statute section from your governing documents.

Illinois Association Law: Comprehensive Breakdown
Illinois is one of the few states that maintains two separate statutes for community associations depending on structure and size. Here is what every board member and homeowner must know.
(a) Two Statutes, Two Scopes
The Illinois Condominium Property Act, 765 ILCS 605, applies to every condominium and cooperative association in the state regardless of size. The Illinois Common Interest Community Association Act, 765 ILCS 160, applies to non-condominium associations — townhome and single-family HOAs — but only when the association has 11 or more units AND annual assessments exceeding $100,000. Smaller non-condo associations are exempt from 160 unless they voluntarily opt in through their governing documents. Knowing which statute governs your community determines which meeting notice rules, lien procedures, and disclosure obligations apply.
(b) Board Meeting Notice — §18(a)
Under 765 ILCS 605/18(a), board meetings require at least 48 hours' notice, which must be posted in a conspicuous place in a common area of the property. This relatively short notice period allows boards to address time-sensitive matters while still giving unit owners a meaningful opportunity to attend and observe most board business, since Illinois condominium meetings are presumptively open to unit owners except for specific matters such as litigation strategy or personnel issues that may be discussed in closed session.
(c) Annual Meeting Notice — §18(b)
For the annual membership meeting, 765 ILCS 605/18(b) requires notice of 10 to 30 days, and the notice must state the time, place, and purpose of the meeting. This window gives owners adequate lead time to arrange attendance while preventing associations from providing so much advance notice that the information becomes stale. Associations that fail to meet this window risk having actions taken at the meeting challenged by owners who did not receive adequate notice.
(d) Quorum Rules for Larger Associations
For associations with 20 or more units, the default quorum for membership meetings is 20% of the total ownership percentage interest, unless the declaration or bylaws set a higher threshold. Notably, a unit owner who is more than 60 days delinquent in assessments is excluded from the quorum count for most matters, although that owner retains the right to vote on any proposed amendment to the bylaws. This distinction matters for associations with significant delinquency, since it can be harder to reach quorum for routine business even though delinquent owners still have a voice on governance changes.
(e) Assessment Liens — Automatic Attachment
Illinois law provides that an association's assessment lien attaches automatically upon a unit owner's default — no separate filing or recording is required to perfect the lien. The lien is subordinate only to real estate tax liens and to encumbrances (such as a first mortgage) that were recorded before the date of the default. When a unit is sold at a foreclosure or judicial sale, the purchaser's liability for unpaid assessments is capped by a 6-month look-back period, meaning the new owner is generally responsible only for the assessments that accrued in the 6 months preceding the sale, not the full arrears.
(f) 2025 Amendments — SB 2740 and HB 5502
Two notable 2025 amendments took effect January 1, 2025. SB 2740 added protections around disability parking accommodations at 765 ILCS 605/18.12, clarifying associations' obligations to unit owners who require accessible parking. HB 5502 bars associations from using discriminatory right-of-first-refusal provisions or from denying a sale solely because the buyer is using FHA financing, closing a gap that had disadvantaged some buyers in Illinois condominium transactions. Boards should review their governing documents to ensure any right-of-first-refusal clauses comply with the new restrictions.
Reserve Funding in Illinois: A Notable Gap
Unlike states such as California or Washington, Illinois does not currently mandate a periodic reserve study. This is one of the most important due-diligence gaps for Illinois owners and buyers to understand.
No Statewide Reserve Study Mandate
Illinois currently has no law requiring associations to commission a periodic reserve study. Instead, the Condominium Property Act requires that the annual budget disclose whether reserves are being funded in accordance with a reserve study or some other methodology, and disclose the current reserve balance. This is a disclosure-based approach rather than a study-based mandate: an association can technically comply by stating it does not use a reserve study at all, as long as that fact is disclosed to owners in the budget.
HB 2563 / SB 1703 — Stalled Legislation
A 2025 legislative effort, HB 2563 and its companion SB 1703, would have required Illinois associations to obtain a reserve study at least every 5 years. Both bills stalled in committee and did not pass during the session. Because momentum for reserve study legislation has been building nationally following high-profile structural failures in other states, Illinois owners and boards should watch for similar proposals in future sessions, but as of today no such requirement is in force.
Why This Matters for Buyers
Because Illinois does not require a reserve study, the financial health of an association can vary enormously even among comparable buildings. A prospective buyer should specifically request the association's reserve fund balance, recent special assessment history, and any internal capital planning documents, since there is no guarantee a formal study exists. Lenders reviewing condo project approvals often ask about reserve funding levels directly, and an association that cannot produce clear reserve documentation may face financing friction for buyers even without a legal violation occurring.
Practical Steps for Boards
Even without a legal mandate, many well-run Illinois associations voluntarily commission a reserve study every few years as a best practice, since it strengthens the budget disclosure required under the Act and reduces the risk of large, unplanned special assessments. Boards that adopt this practice can point to a documented funding plan when owners ask hard questions about assessment increases, and it may improve the association's standing with mortgage lenders reviewing the building for approval.
Illinois HOA Meetings, Quorum, and Voting
Illinois law sets specific notice periods and quorum defaults that boards must follow to keep meetings and votes legally valid.
Board Meeting Requirements
Board meetings under 765 ILCS 605/18(a) require a minimum of 48 hours' notice, posted conspicuously in a common area accessible to all unit owners. Most board business must be conducted in an open meeting that owners may attend as observers, with limited exceptions for matters such as pending or probable litigation, personnel matters, and contract negotiations, which may be discussed in closed session. Associations that regularly fail to post timely notice risk owner challenges to decisions made at improperly noticed meetings.
Annual Meeting Notice Window
The annual membership meeting requires notice of no fewer than 10 and no more than 30 days under §18(b). The notice must state the time, place, and purpose of the meeting so owners can decide whether specific agenda items require their attendance or a proxy. Because the window is bounded on both ends, associations cannot send notice too far in advance, which helps ensure the information owners receive remains current and relevant to the meeting itself.
The 20% Quorum Default
For associations with 20 or more units, the statutory default quorum is 20% of the total ownership percentage interest unless the declaration or bylaws set a higher threshold. Smaller associations, or those whose governing documents specify a different quorum, follow their own documents instead. Because reaching quorum can be a persistent challenge, especially in larger buildings with absentee owners, many associations rely heavily on proxies to ensure meetings can proceed and business is not repeatedly postponed.
Delinquent Owners and Quorum
A unit owner who is 60 or more days delinquent in paying assessments is excluded from the quorum count for most membership votes. This rule prevents a large block of delinquent owners from either blocking quorum entirely or being counted toward a quorum they have no practical stake in reaching. Importantly, this exclusion does not strip the delinquent owner of all voting rights: they retain the right to vote on any proposed bylaw amendment, reflecting the legislature's intent to balance financial accountability with fundamental governance rights.
Practical Tips for Reaching Quorum
Associations that struggle to reach quorum should build a proxy collection campaign into their annual meeting notice mailing, remind owners early and often, and consider whether their bylaws allow electronic or mail-in voting to increase participation. Boards should also track which owners are 60+ days delinquent before the meeting so the quorum calculation is accurate, since miscounting can create grounds for an owner to challenge decisions made at a meeting that technically lacked quorum.
Illinois Assessment Liens and Collections
Illinois gives associations one of the more owner-friendly automatic lien mechanisms in the country, paired with a meaningful cap that protects foreclosure-sale buyers.
Automatic Lien Attachment
Unlike states that require an association to record a claim of lien before it takes priority, Illinois law provides that the assessment lien attaches automatically the moment a unit owner defaults on payment — no separate recording is required for the lien to exist. This makes it comparatively simple for associations to establish a lien position, though pursuing foreclosure or other collection remedies still requires following the statute's procedural requirements and, typically, counsel.
Lien Priority
The association's lien is subordinate only to two categories: real estate tax liens, and encumbrances (most commonly a first mortgage) that were recorded before the date of the unit owner's default. This means the association's lien generally has priority over liens recorded after the default date, giving associations meaningful leverage in collection even when a mortgage exists on the unit, as long as the mortgage was recorded after the default occurred.
The 6-Month Look-Back Cap
When a unit changes hands through a foreclosure or judicial sale, Illinois law caps what the purchaser can be required to pay toward the prior owner's unpaid assessments at approximately 6 months' worth of arrears, rather than the full accumulated debt. This look-back cap protects buyers at foreclosure sales from inheriting years of delinquency, while still ensuring the association can recover a meaningful portion of what it is owed from the proceeds or the new owner.
Practical Collections Guidance
Associations pursuing delinquent owners should document the default date carefully, since it determines both lien priority against later-recorded encumbrances and the look-back period a foreclosure buyer will owe. Consistent, well-documented collections practices — including timely late notices and a clear written policy — reduce disputes and support the association's position if collection matters proceed to court.
How IgeraFincas Works for Illinois Associations
Upload your governing documents
Upload your declaration, bylaws, rules, budget disclosures, and board meeting minutes to IgeraFincas. The platform supports PDF, Word, and scanned documents. Most Illinois association document packages are processed and indexed within 2 hours. Your documents are stored securely with encryption at rest and in transit, and are never used to train any shared AI model.
Configure your community widget
Embed the IgeraFincas widget on your association's website or resident portal with one line of code. Customize the greeting, color scheme, and the specific documents the AI references. You can configure different widgets for different communities if you manage multiple Illinois associations — each with its own document set and context, whether governed by 765 ILCS 605 or 765 ILCS 160.
Residents ask questions 24/7
Owners type their questions in plain language at any hour. IgeraFincas searches the indexed governing documents and the relevant Illinois statute simultaneously, returning an answer that cites the specific section it relied on. No more calls to the management company for questions that can be answered by reading the declaration.
Board receives analytics and gap reports
The board dashboard shows every question residents asked, how the AI answered, and which questions the AI could not answer (content gaps). Gap reports help boards identify which topics need clearer policies or additional documentation. For Illinois associations this is especially valuable for clarifying reserve funding disclosures, since no formal reserve study is legally mandated.
Continuous updates as laws change
Illinois community association law is actively evolving — SB 2740 and HB 5502 both took effect in 2025, and reserve-study legislation has already been introduced once. IgeraFincas keeps its Illinois statute knowledge base current with amendments to 765 ILCS 605 and 765 ILCS 160, so your AI assistant reflects the law as it stands today.
IgeraFincas resolves a real Illinois condo association question
A unit is being sold through foreclosure and the owner has 14 months of unpaid assessments. How much can we actually collect from the buyer?
Under the Illinois Condominium Property Act, 765 ILCS 605, the association's assessment lien attached automatically when the owner first defaulted — no recording was required. However, when the unit sells at a foreclosure or judicial sale, the purchaser's liability for unpaid assessments is capped by a 6-month look-back period. That means the buyer is generally only responsible for approximately the most recent 6 months of arrears, not the full 14-month balance. For the remaining arrears, the association would need to pursue a claim against the prior owner directly or through the foreclosure proceeds, since the buyer's statutory exposure is limited. Recommend confirming the exact default date and the lien's recorded priority against the mortgage with association counsel before finalizing the collection amount.
Case Study: Chicago Condominium Association, 210 Units
A 210-unit condominium association in Chicago's Lakeview neighborhood deployed IgeraFincas to manage resident Q&A after its self-managed board struggled to keep up with a growing volume of owner inquiries.
The Challenge
The association is self-managed by a volunteer board of five owners, with no on-site property manager. Board members reported spending 6 to 10 hours per week collectively answering resident emails and phone calls about assessment due dates, parking assignments, pet policy, and how reserve funding was being handled — a recurring point of confusion since owners assumed (incorrectly) that Illinois required a formal reserve study. The board wanted a way to answer routine questions consistently without burning out volunteer directors.
The IgeraFincas Implementation
IgeraFincas was deployed with the declaration, bylaws, rules and regulations, the last two annual budget disclosures, and board meeting minutes from the prior 18 months. The widget was embedded on the association's resident portal and linked from the treasurer's email signature. The knowledge base was configured to reference both the governing documents and the Illinois Condominium Property Act directly, so residents received answers grounded in the actual statute language whenever a question touched on legal requirements rather than just building policy.
Results After 6 Months
Board members reported that weekly time spent on resident inquiries fell from 6-10 hours to roughly 2 hours, with IgeraFincas resolving the large majority of routine questions without volunteer intervention. Response time for after-hours questions improved dramatically, since owners previously had to wait until the next board meeting or a director's availability to get an answer. The treasurer noted that questions about reserve funding dropped significantly once residents could get a clear, cited explanation of how the association discloses its funding approach under Illinois law.
Governance Impact
Using the gap analysis report, the board identified that the largest cluster of unanswered questions concerned the association's informal reserve funding practices. In response, the board voluntarily commissioned its first professional reserve study the following fiscal year — even though Illinois law does not require one — specifically to give owners a clearer funding roadmap and strengthen the building's standing with mortgage lenders reviewing unit sales.
Frequently Asked Questions — Illinois HOA & Condo Law
Which law applies to my Illinois community — 765 ILCS 605 or 765 ILCS 160?+
If your community is a condominium or cooperative, the Illinois Condominium Property Act (765 ILCS 605) applies regardless of size. If your community is a non-condo HOA — townhomes or single-family homes — the Common Interest Community Association Act (765 ILCS 160) applies only if the association has 11 or more units and annual assessments exceeding $100,000. Smaller non-condo associations are exempt from 160 unless they choose to opt in through their governing documents.
Is my Illinois association required to conduct a reserve study?+
No, not currently. Illinois has no statewide law requiring a periodic reserve study. Associations must disclose in their annual budget whether reserves are funded in accordance with a study or another methodology, but a study itself is not mandatory. A 2025 bill (HB 2563 / SB 1703) that would have required a study every 5 years stalled in committee and did not become law. Owners and buyers should ask directly about reserve funding since no study is guaranteed to exist.
How much notice is required for an Illinois board meeting?+
Under 765 ILCS 605/18(a), board meetings require at least 48 hours' notice, posted in a conspicuous place in a common area of the property. Annual membership meetings require a longer window under §18(b): between 10 and 30 days' notice, stating the time, place, and purpose of the meeting.
Does a delinquent owner still get a vote in my Illinois association?+
A unit owner who is 60 or more days delinquent is excluded from the quorum count for most membership votes. However, that owner is not stripped of all voting rights: Illinois law specifically preserves their right to vote on any proposed bylaw amendment even while delinquent. For associations with 20 or more units, the default quorum is 20% of the ownership percentage interest unless the declaration or bylaws set a higher threshold.
Does my Illinois association need to record a lien before it takes priority?+
No. In Illinois, the assessment lien attaches automatically upon a unit owner's default — no separate recording is required. The lien is subordinate only to real estate tax liens and to any encumbrance, such as a mortgage, that was recorded before the date of default. If the unit is later sold at foreclosure, the purchaser's liability for unpaid assessments is capped by a 6-month look-back period.
What changed in Illinois condo law in 2025?+
Two amendments took effect January 1, 2025. SB 2740 added disability parking provisions at 765 ILCS 605/18.12. HB 5502 prohibits associations from applying discriminatory right-of-first-refusal provisions or denying a sale solely because the buyer is using FHA financing. Boards should review their governing documents and any right-of-first-refusal clauses to confirm compliance with these changes.
If a buyer purchases a unit at foreclosure, how much of the old debt do they owe?+
Illinois law caps a foreclosure-sale purchaser's liability for the prior owner's unpaid assessments at approximately a 6-month look-back period, rather than the full accumulated arrears. This protects buyers from inheriting years of delinquency while still giving the association a meaningful, prioritized claim against the sale proceeds or the prior owner for the remaining balance.
