Key Lease Addendums Illinois Renters Should Understand

Leasing an apartment in Illinois often means reviewing not just the standard lease, but also a range of addendums. These additional documents can significantly affect your rights and responsibilities. Knowing what they are and how they work is crucial for every renter in Illinois. This article explains common lease addendums, your protections under Illinois law, and practical steps to safeguard your housing situation.

What Is a Lease Addendum?

A lease addendum is an extra document that changes or adds specific terms to the main rental agreement. Unlike standard clauses, these addendums address unique issues—such as pets, smoking rules, or property modifications. In Illinois, both landlord and tenant must agree to and sign addendums for them to take effect.

Common Lease Addendums in Illinois

Here are several types of lease addendums Illinois renters may encounter. Each can impact your living situation, so review them thoroughly before signing.

• Pet Addendum: Lays out rules around pet ownership, fees, and restrictions. Some addendums may require service animal accommodation documentation for support or service animals.
• Lead-Based Paint Disclosure: Required by federal law for buildings constructed before 1978. This addendum must accompany rental agreements to warn about potential lead hazards, and includes the "Disclosure of Information on Lead-Based Paint and/or Lead-Based Paint Hazards" form.
• Bed Bug Addendum: Landlords in some Illinois cities, like Chicago, must provide information about bed bug prevention and disclosure (see the Chicago Residential Landlord Tenant Ordinance for details).
• Smoke-Free Addendum: Sets policies on smoking within units or common areas. Ensure you understand the penalties for violating this provision.
• Alteration or Renovation Addendum: Outlines whether tenants can make changes (like painting or mounting décor) and who is responsible for repairs when moving out.
• Early Termination Addendum: Explains options and fees for ending your lease before the contract term ends.
• Subletting Addendum: Specifies rules for renting your space to others, including written landlord approval and possible background checks.
• Crime-Free Addendum: Prohibits illegal activity on the premises. Violation may be grounds for eviction under Illinois law.

Are Lease Addendums Legal in Illinois?

Yes, as long as the terms comply with the Illinois Residential Tenants' Right to Repair Act and Illinois Security Deposit Return Act, as well as any applicable local ordinances such as the Chicago Residential Landlord and Tenant Ordinance (RLTO).
Remember, any addendum that tries to waive your basic rights under state or federal law is not enforceable.

Important State Forms and How They Affect Renters

• Lead-Based Paint Disclosure Form (Form EPA 747-K-99-001):
  Required for rentals built before 1978. As a practical example, your landlord should present this form when you sign your lease. If not, ask for it. View the official disclosure form.
• Notice to End Lease (No official form, written notice required):
  Either party wishing to end a month-to-month lease must provide written notice (at least 30 days in advance). See the Illinois Landlord and Tenant Act for notice periods.
• Rental Assistance or Housing Complaint Forms:
  If experiencing issues with unfair lease addendums or housing conditions, renters can file complaints with the Illinois Housing Development Authority (IHDA) or local housing departments. Each agency provides its own complaint form online or upon request.

Your Rights and Protections under Illinois Lease Laws

Illinois law gives renters strong protections. For example, a landlord cannot change core terms of your lease, such as increasing rent or restricting pets, unless you—and all tenants named on the lease—sign a new agreement or addendum. The law also restricts hidden fees or "surprise" clauses that violate local or state regulations.

What to Do If You Disagree with an Addendum

If you receive an addendum you’re not comfortable with:

• Communicate with your landlord—many issues can be clarified or negotiated.
• Do not sign until you fully understand and agree to all terms.
• If pressured or unsure, contact a renter or legal aid organization for guidance.
• If the addendum violates your rights under the Illinois Security Deposit Return Act or other state laws, report concerns to the appropriate authority (see Resources below).

Resources for Lease Disputes in Illinois

Disagreements about addendums can often be resolved by contacting the local housing authority or the landlord-tenant tribunal. In Illinois, disputes may ultimately be heard in county court, but many cities have local boards or departments to help renters and landlords reach resolution.

• City of Chicago Department of Housing: Renter Resources
• Illinois Housing Development Authority (IHDA)
• Illinois Attorney General: Landlord and Tenant Rights & Laws
