How RUBS Utility Billing Works for Connecticut Renters

Many Connecticut renters receive utility bills through a system called Ratio Utility Billing System (RUBS). If you’ve noticed a separate charge for water, gas, or electricity on top of your rent – and it doesn’t match your usage – your landlord might be using RUBS. Here’s what you need to know about RUBS in Connecticut, your legal protections, and practical steps to resolve any issues.

What Is RUBS Utility Billing?

RUBS, or Ratio Utility Billing System, is a way landlords allocate monthly utility costs among tenants based on formulas (like apartment size or number of occupants) rather than separately metered usage. This is common when individual units don’t have their own meter for water, gas, or trash service.

How RUBS Charges Are Calculated

In RUBS, landlords divide the building’s utility bill using factors such as:

  • Number of people living in each unit
  • Square footage of each apartment
  • Number of bedrooms or bathrooms

Connecticut law does not currently regulate the formulas landlords must use for RUBS, but landlords must follow the lease agreement and state landlord-tenant law. If utility charges are not fairly disclosed, tenants may have rights to dispute them.

Your Rights under Connecticut Tenancy Law

Under the Connecticut Landlord and Tenant Act (Chapter 832, CGS §§ 47a-1 to 47a-20e), tenants are protected against unfair billing and must receive clear disclosures of all charges at lease signing. The law requires landlords to:

  • State in the lease if you must pay for utilities separately
  • Disclose how utility charges are calculated and divided
  • Provide accurate billing information

What Should Be in Your Lease?

If your landlord uses RUBS, your lease should clearly state:

  • Which utilities you pay for
  • How the charges are calculated (for example, based on occupancy)
  • How and when you’ll be billed

If this language is missing or unclear, you have the right to request more information and may be able to dispute unexplained charges.

If You Dispute a RUBS Charge

If you find unexpected utility charges or suspect your RUBS bills are incorrect:

  • Review your lease for the utility billing section
  • Ask your landlord for a written explanation of the formula used
  • Request copies of the master utility bill if you believe you’re overcharged
  • If issues remain, you may file a complaint with the Connecticut Department of Consumer Protection or pursue action in Small Claims Court
If you are unsure whether your lease is clear about RUBS or utility charges, ask your landlord for written clarification – and keep a copy for your records.

Are RUBS Charges Legal in Connecticut?

Connecticut law does not specifically ban RUBS, but state law requires all lease terms (including RUBS) to be clearly explained and agreed in writing. Unexplained or unpredictable utility billing could be challenged as an unfair or deceptive practice under Connecticut General Statutes.

Renters: How to Protect Yourself

  • Always review your lease thoroughly before you sign. Watch for clauses about utility allocation or RUBS.
  • Request details in writing of how your portion of utilities is determined.
  • Keep all documents and bills as proof in case of dispute.
  • If you believe the charges violate your rights, you can file a complaint or seek legal advice.

FAQs about RUBS Utility Billing in Connecticut

  1. Can landlords charge for utilities with RUBS in Connecticut?
    Yes – if your lease clearly explains the method. All charges should be disclosed, and the calculation method should be transparent.
  2. What if I never agreed to pay utilities separately?
    If your lease does not state you must pay utilities as a separate charge, or if new charges appear mid-lease, contact your landlord for clarification. You may not be liable for undisclosed RUBS charges.
  3. How do I dispute a RUBS charge in Connecticut?
    First, talk to your landlord in writing. If the issue isn’t resolved, file a complaint with the Connecticut Department of Consumer Protection or consider small claims court.

    Contact the Department of Consumer Protection, local legal aid, or your town’s Fair Rent Commission if available.
