Identify the ownership structure first

Confirm whether you are buying a condominium interest or a cooperative interest. Chicago's zoning-certificate ordinance distinguishes a co-op's stock and proprietary lease arrangement from individual condominium title, and the zoning certificate is not required for condominium or cooperative residential property (3-33-045 exemption). That difference changes the documents, financing questions, transfer process, and risk review. A building's appearance or casual use of the word apartment does not establish the legal structure.

For a condominium resale, Illinois Section 22.1 provides a framework for requested association information: the selling owner obtains it from the association, and the association's principal officer or designated officer must furnish it within 10 business days of a written request. The association may charge the seller a reasonable fee, capped at $375 in the statute and adjusted annually by the change in the consumer price index. From January 1, 2027 (P.A. 104-734), the list also includes the association's collection policy. Review the text in effect for the transaction date. Do not apply that condominium framework wholesale to a co-op.

  • Confirm legal ownership documents.
  • Identify all included parking and storage rights.
  • Ask the lender about this exact structure.

Read finances alongside planned work

Obtain the governing documents and available financial records before the relevant contract deadline. Read operating expenses, reserve information, anticipated capital work, insurance, litigation information, and unit-specific charges together. A reserve balance has little meaning without understanding the building's needs and commitments.

Ask what is documented, what remains under discussion, and whether a proposed charge has actually been approved. Build a list of unresolved items for legal, financial, and lender review. No single reserve percentage or monthly assessment can certify that an association is financially healthy.

  • Match capital plans to funding.
  • Identify owner responsibilities separately.
  • Request written explanation of unusual charges.

Inspect the shared building as well as the unit

A freshly decorated unit can sit beneath an aging roof or within a building that needs masonry, elevators, or drainage work. Ask which common areas can be inspected and what specialist reports already exist. An inspection limited to the interior should not be described as a complete assessment of the building.

Compare meeting records and capital plans with what you observe. An item repeatedly discussed without a funding plan deserves a specific question. The goal is to understand the likely exposure and your ability to live with it, not to predict every future assessment.

  • Review roof and exterior information.
  • Check water history and shared mechanical systems.
  • Confirm inspection scope in writing.

Test your intended use against rules and financing

Read rules for leasing, pets, alterations, deliveries, move reservations, and outdoor space before assuming the unit fits. Verify whether parking is deeded, assigned, leased, or otherwise controlled. In a co-op, request the applicable transfer and occupancy documentation and understand approval steps; do not assume condominium practices carry over.

Submit the exact building and ownership details to the lender early. Personal preapproval does not answer every building eligibility question. Keep financial review and daily-use review separate so a financeable apartment is not mistaken for one that supports your plans.

  • Read restrictions rather than relying on a verbal summary.
  • Confirm the move process.
  • Resolve building financing conditions early.

Planning guidance

How does buying a co-op differ from buying a condo?

Confirm the legal structure: a co-op generally involves an ownership interest in the organization and occupancy through a proprietary lease or similar arrangement, rather than title to an individual condominium unit.

More questions in this guide

How should I judge a condo association's reserves?

Read the balance together with planned work, building condition, commitments, and available reserve studies or specialist reports. Ask how large projects will be funded and whether proposed assessments are approved or only discussed. There is no single figure in this guide that proves adequacy. Evaluate the exposure against your own reserves and the lender's review rather than treating a low assessment as automatic value.

Planning guidance

What should I ask about a special assessment?

Request the approved resolution or other written evidence, purpose, amount allocated to the unit, payment schedule, and any remaining work. Distinguish an existing assessment from a proposed one. Ask how the purchase contract allocates the obligation and whether financing or insurance is affected. Keep the legal allocation separate from your cash planning; an answer about who pays does not describe project disruption.

Planning guidance

Can a lender reject a building even if I am preapproved?

Your personal borrowing assessment and the property's eligibility are separate questions. Ask the lender what project or co-op review applies and submit the building information early. Association records, coverage, use, or other characteristics may require additional review under that loan program. Do not remove financing protections because a personal preapproval letter exists; request confirmation of unresolved building-specific conditions and dates.

Planning guidance

Does a unit inspection cover the whole condominium building?

Only to the extent stated in the inspection agreement and available access. Ask what common areas, exterior systems, and records will be considered and where specialist evaluation is needed. Compare the inspection limitations with association maintenance information. A report on appliances and visible unit systems cannot establish the condition or funding needs of every roof, elevator, facade, or concealed shared component.

Planning guidance

How can I verify parking and storage included with a unit?

Request the documents establishing the rights and confirm how they are transferred. Identify the space, any separate parcel or charge, and whether the arrangement is deeded, assigned, leased, or subject to change. Test physical access and dimensions where allowed. A space used by the seller is not enough evidence that your purchase includes the same continuing right or total cost.

Planning guidance

Which building rules matter before making an offer?

Read the provisions affecting your plans: pets, leasing, alterations, moving, guests, deliveries, outdoor space, and parking. Ask whether an exception is documented and transferable rather than assuming a seller's practice is permitted for you. For a co-op, use the organization's own occupancy and governance material. If a rule conflicts with a non-negotiable requirement, address it before committing to the unit.

    The official text shows the current section (P.A. 102-976, effective January 1, 2023) and an amendment by P.A. 104-734, effective January 1, 2027, that adds a copy of the association's collection policy adopted under Section 18.4(t) to the resale disclosure list. The listed information is furnished within 10 business days of a written request. The association may charge the unit seller a reasonable fee for direct out-of-pocket costs, capped at $375 in the text and adjusted annually for consumer-price-index changes; an additional $100 may be charged for rush service completed within 72 hours. Confirm the text in effect on your transaction date.
