What is the RLTO?

The RLTO is a Chicago municipal ordinance that governs the relationship between residential landlords and tenants. It applies to most rental units within Chicago city limits and covers:

  • Security deposit limits and requirements
  • Required written disclosures before signing a lease
  • Notice requirements for lease termination
  • Remedies for both landlord and tenant violations
  • Prohibition on retaliatory conduct

Does the RLTO Apply to You?

The RLTO applies to most residential rentals in Chicago, but there are exceptions:

  • • Owner-occupied buildings with 6 or fewer units
  • • Hotels, motels, and rooming houses
  • • Rentals in suburbs (they have different rules)

The RLTO has very specific requirements for security deposits. Landlord violations can result in significant penalties.

Required Disclosures

Before you sign a lease, your landlord must provide these written disclosures:

Required Written Disclosures

  • RLTO Summary

    A summary of the ordinance's provisions (the city publishes this)

  • Owner/Agent Information

    Name and address of owner or authorized agent

  • Building Code Violations

    Any pending code violations issued within the previous 12 months

  • Lead Paint Disclosure

    For buildings built before 1978 (federal requirement)

  • Radon Disclosure

    Illinois state requirement

Penalty: If landlord fails to provide required disclosures, tenant may terminate the lease within 30 days of taking possession.

Notice Requirements

The RLTO specifies how much notice landlords and tenants must give:

Notice Periods

Year-long lease (non-renewal)30 days
Month-to-month lease30 days
Week-to-week lease7 days

Notice must be in writing. Oral notice is not sufficient.

Tenant Remedies

The RLTO provides several remedies if your landlord fails to maintain the property:

1. Repair and Deduct

If a landlord fails to maintain the premises in compliance with building code after proper notice, tenants may make necessary repairs and deduct the cost from rent (up to $500 or half month's rent, whichever is greater).

2. Rent Withholding

For material noncompliance affecting health and safety, tenants may withhold rent after proper notice, but should put the withheld rent in escrow.

3. Lease Termination

For certain violations, tenants may terminate the lease with proper written notice.

Important Warning

Before using any RLTO remedy (especially rent withholding), consult with a tenant rights organization or attorney. Improper use could put you at risk of eviction.

Protection from Retaliation

The RLTO prohibits landlords from retaliating against tenants who:

  • Complain to a government agency about code violations
  • Complain to the landlord about repairs
  • Exercise rights under the RLTO
  • Join or organize a tenant union

Retaliatory actions include raising rent, decreasing services, or beginning eviction proceedings. If retaliation occurs within 12 months of protected activity, it's presumed retaliatory.

Enforcing Your Rights

If your landlord violates the RLTO, you have several options:

  1. Document everything — Keep copies of all communications, photos, and receipts
  2. Send written notice — Many RLTO remedies require written notice first
  3. Contact a tenant organization — Metropolitan Tenants Organization: (773) 292-4988
  4. File in court — You can sue in small claims court for RLTO violations

Check Building Violations Before You Rent

Under the RLTO, landlords must disclose pending code violations. But you can also check yourself on StreetSmart.
