RUBS Utility Billing: What Arizona Renters Need to Know

Many Arizona renters receive their utility bills through a system called RUBS (Ratio Utility Billing System). While this approach can simplify billing for landlords and property managers, it raises important questions for tenants about fairness, accuracy, and renters’ rights under Arizona law. Here, we walk through everything you need to know about RUBS utility billing and where to get support if you have concerns.

What Is RUBS Utility Billing?

RUBS (Ratio Utility Billing System) is a method landlords use to divide utility costs—such as water, sewer, trash, or sometimes even electricity or gas—among multiple rental units. Instead of individual utility meters for each unit, the landlord receives a total utility bill, which is then split among tenants using a set formula, often based on:

• Number of occupants in each unit
• The square footage of each apartment
• A combination of factors, or other fair standards

Arizona law allows landlords to use RUBS billing if it is clearly outlined in the lease agreement and the method of calculation is reasonable and transparent^[1]. RUBS is common in apartment complexes and multi-unit dwellings that do not have individual meters for all utilities.

Your Rights and Responsibilities with RUBS in Arizona

As a renter, you are protected by the Arizona Residential Landlord and Tenant Act. Some important points:

• Disclosure: Landlords must state in your lease that utilities will be billed using RUBS, describing the formula being used.
• Reasonableness: The charges must be based on a “reasonable” method—not arbitrary or discriminatory.
• Access to Records: You have the right to request documentation showing how your portion of the bill was calculated.
• Prohibited Practices: Landlords cannot profit from utility billing. If the landlord collects more than the actual cost, you may have legal grounds to contest the charges.

If you have concerns about RUBS billing or think the charges are unfair, it helps to review your lease and communicate in writing with your landlord. The “utility use statement” is essential when questioning bills. According to Arizona law, landlords must provide this breakdown upon request^[2].

Official Forms and Complaint Procedures for Renters

• Arizona Residential Landlord and Tenant Complaint Form: This form can be used if negotiation with your landlord fails or if you believe your utility billing is unlawful. Access the form and filing instructions via the Arizona Attorney General’s Landlord-Tenant Resources.

Example: If you suspect your landlord is overcharging through RUBS or not disclosing the billing formula, complete this complaint form and submit it as directed to start an investigation.

The Tribunal Overseeing Tenant-Landlord Disputes

The official body handling tenant-landlord matters in Arizona is the Arizona Justice Courts, where most landlord and tenant disputes are heard. For consumer-focused complaints (including utilities), the Arizona Attorney General’s Civil Rights Division may also assist with certain issues.

Tips for Arizona Renters Using RUBS

• Always review your lease to understand how utilities are billed.
• If your charges change significantly, ask your landlord for a written breakdown or actual utility statements.
• Keep personal records of all utility bills, statements, and communications with your landlord about utilities.
• If a dispute arises, try to resolve it in writing. If this fails, you may file a complaint or seek legal assistance.
