Preparing a property-condition question list in Oak Lawn
A guide for Oak Lawn homeowners to create a property-condition question list using Illinois disclosure laws and Cook County property record resources.
The short answer
To effectively evaluate property conditions in Oak Lawn, sellers must prepare a written disclosure report addressing all known material defects, as required by the Illinois Residential Real Property Disclosure Act. Buyers should complement this by researching the Cook County Assessor’s site and permit portals to verify history before committing to a final purchase contract.
Understanding Disclosure Requirements
Illinois law mandates that sellers of 1-to-4 unit residential properties provide a written disclosure report before a contract is signed. This document must list material defects affecting property value or health and safety.
Sellers are not required to perform new inspections; however, they must disclose known issues. Omissions based on incorrect data provided by professionals may offer legal defenses.
Utilizing Cook County Research Tools
Oak Lawn properties fall under Cook County's jurisdiction. You can use the Cook County Assessor’s portal to review property records and verify tax exemptions. Checking the permit and inspection portal provides insight into past renovation history.
Worksheet: Document the date of every permit search performed, the specific agency link used, and the findings regarding active or closed project records.
Drafting Your Question List
Prepare questions regarding structural integrity, HVAC age, and foundation status. Ask if the seller holds copies of past permits for additions or major interior work.
Example: Ask the seller, 'Have you received any written notice of building code violations from the Village of Oak Lawn that remain unresolved?'
Addressing Material Defects
Material defects are conditions that significantly impair the property value or habitability. If you discover a defect after the contract is signed, you may have up to five business days to terminate if the seller provides a supplemental disclosure.
Always consult a qualified attorney if you are unsure whether a specific property condition meets the state's legal definition of a material defect.
Checklist
- Review the Residential Real Property Disclosure report provided by the seller.
- Check the Cook County Assessor’s website for the current tax exemption status.
- Search the Cook County permit portal for records of recent home improvements.
- Verify if any major renovations required demolition permits through the county.
- Ask a local building expert to clarify any unclear records discovered during your search.

Common questions
Must an Oak Lawn seller fix every defect they disclose?
No. The Residential Real Property Disclosure Act requires disclosure of known material defects but does not mandate repairs. You may negotiate 'as is' contracts regardless of these disclosures.
What happens if I find a defect the seller failed to list?
If you uncover a material defect that was known to the seller but omitted from the report, you may have grounds to seek damages under Illinois law. Consult a legal professional to discuss your specific rights and the one-year statute of limitations.
