Reviewing home-improvement documents before a Berwyn sale

Essential steps for Berwyn homeowners to document home improvements for legal compliance and property valuation using Cook County and local records.

By SQFT IO · Published · 2 min read

The short answer

Berwyn sellers should organize all home-improvement records to ensure compliance with the Illinois Residential Real Property Disclosure Act. While the Act does not require sellers to perform new investigations, maintaining organized permit and inspection documentation helps confirm that previous work was performed legally and helps buyers assess the property’s current condition.

Organizing Permit Documentation

The Illinois Residential Real Property Disclosure Act requires transparency regarding property conditions. If you have improved your home, keep copies of all issued building permits and final inspection sign-offs.

Hypothetical Planning: Create a binder labeled 'Berwyn Home History.' Insert permits for roofing, plumbing, or electrical work, and document the contractor’s name and the year the work was completed.

Verifying Cook County Property Records

Sellers should check their property status through the Cook County Treasurer and Assessor websites. These sites hold public records of tax assessments and property classifications.

If your assessment seems inconsistent with your recent improvements, research how home additions might influence the equalized assessed value (EAV) in the future.

Clarifying Disclosure Obligations

You are only liable for disclosing material defects of which you have actual knowledge. If you relied on a licensed professional for a repair, you are generally not liable for inaccuracies in the disclosure report.

Always attach the mandatory Illinois disclosure sections to your report. Failing to provide this document gives the buyer the right to terminate the contract.

Supplementing Disclosures

If you become aware of an error in your disclosure after delivering it, you are legally obligated to provide a written supplemental disclosure before closing.

Example: If you discover a previously unknown basement leak after signing the contract, provide a written supplement immediately rather than waiting for the buyer to find out.

Checklist

  • Gather all building permits and inspection certificates for renovations.
  • Locate the most recent property tax bill via the Cook County Treasurer's site.
  • Confirm that your property disclosure form includes the required statutory text.
  • Review records for any known defects that impair health or safety.
  • Consult a professional if you are unsure whether a past repair requires disclosure.

Common questions

Do I need to list minor repairs on my disclosure form?

The law focuses on 'material defects,' defined as conditions that significantly impair health, safety, or value. Routine maintenance is generally not required to be disclosed unless it impacts these core areas.

Can a buyer back out of a Berwyn sale if I disclose a defect?

If you disclose a material defect after the contract is signed, the buyer has five business days to terminate the agreement. Termination rights for supplements are limited unless the defect was known previously or is unrepairable.
