Illinois RUBS Utility Billing: What Renters Need to Know

If you rent in Illinois, you may have noticed that your utility bills are calculated using a system known as RUBS — or Ratio Utility Billing System. This method can be confusing, especially if you are not sure how charges are divided or what your rights are under Illinois law. This guide explains RUBS utility billing in plain language, your legal protections, and how to dispute unfair charges, focusing on helpful steps for Illinois tenants.

What is RUBS Utility Billing?

RUBS stands for Ratio Utility Billing System. In this system, landlords allocate utility costs (such as water, sewer, gas, or electricity used in common areas) among multiple apartments based on a formula. This formula may consider the number of tenants, apartment size, or other factors, rather than using individual meters for each unit.

How RUBS Works in Illinois Rental Housing

• Utilities are not individually metered to each unit but are instead split among tenants using agreed ratios.
• Landlords must disclose the use of RUBS in your lease agreement or in a written addendum.
• Utility charges must be itemized, clear, and based on a reasonable formula.
• As a renter, you have a right to ask for an explanation or breakdown of how your share is calculated.

This method is common in older buildings or multifamily complexes that lack separate meters for each apartment.

Your Rights Under Illinois Law

While Illinois does not have a specific law outlining RUBS utility billing, all rental billing practices must comply with the Illinois Residential Tenants’ Right to Repair Act and the statewide Illinois Security Deposit Return Act. If you rent in Chicago, additional protections are provided under the Chicago Residential Landlord and Tenant Ordinance (RLTO)¹.

• Landlords must act in good faith, providing utility billing details if requested.
• Billing must not be arbitrary or discriminatory.
• Unreasonable or undisclosed charges may be challenged with local tenant authorities or in court.

Official Tribunal for Illinois Renters

In Illinois, rental disputes are generally handled by your local circuit court. For Chicago tenants, the Department of Housing (DOH) - Rents Right Division provides further guidance.

Common Issues and How to Address Them

If you believe you are being overcharged or there is a lack of transparency in RUBS billing, you have options for resolution.

• Request an itemized bill: Ask your landlord for a breakdown showing how your share is calculated.
• Contact local authorities: Your city's Department of Consumer Services or local housing authority can review complaints.
• Use official forms: For Chicago, tenants may utilize the "Residential Landlord/Tenant Complaint Form" from the Department of Housing. This form is used to report suspected ordinance violations or unresolved disputes regarding utility billing.

How to Use the Chicago Residential Landlord/Tenant Complaint Form

• Form Name: Residential Landlord/Tenant Complaint Form (no number listed)
• When Used: When a Chicago renter is facing unresolved billing issues or believes their rights under the ordinance are being violated.
• How to Submit: The form can be found on the Department of Housing website; submit it by email or mail as directed on the form.

For renters outside of Chicago, check with your local city hall or housing agency for complaint procedures and forms.

What Illinois Law Says About Utilities & Billing

Illinois law requires landlords to maintain essential services and prohibits them from shutting off utilities to force a renter out. It does not set specific formulas for RUBS, but any system must be reasonable and disclosed to tenants. Key state laws include:

• Illinois Security Deposit Return Act
• Illinois Residential Tenants’ Right to Repair Act
• Chicago Residential Landlord and Tenant Ordinance (RLTO)

Review any applicable local ordinances, especially if you live outside Chicago, as city rules may differ.

Frequently Asked Questions About RUBS Utility Billing in Illinois

1. Is my landlord required to tell me if they use RUBS billing?
   Yes. In Illinois, lease agreements or addenda should clearly state the method used to allocate utility costs. If utility billing is not clearly disclosed, renters may request more information or file a complaint if they believe charges are unfair.
2. Can I dispute charges if I think my share of the utilities is too high?
   Yes, you have the right to request an itemized bill and to raise concerns with your landlord, the local housing department, or your city’s consumer services.
3. What if my landlord fails to provide essential utility services?
   State law prohibits landlords from intentionally shutting off essential services. Tenants may be able to withhold rent, pay for the utility themselves and deduct from rent, or file a complaint. Always consult the Illinois Residential Tenants’ Right to Repair Act for proper procedure.

   Most Illinois cities handle concerns through their housing authority or consumer protection department; check your local government’s website for forms and instructions.
