When individual meters are not available, a Ratio Utility Billing System (RUBS) is used to allocate the cost of utilities in a multifamily or commercial building to tenants. To estimate each tenant’s portion of the utility expenditures, RUBS considers a variety of parameters, including the square footage of each unit, the number of occupants, and the type of appliances utilized.
Landlords like RUBS (ratio utility billing system) because it allows them to recoup utility costs without having to install individual meters. It is also a more precise method of allocating utility expenditures than just distributing them equally among all tenants.
One option is to charge a monthly flat rate utilities cost in addition to rent. However, there are also significant negatives to this because utility costs vary greatly among locations. Furthermore, tenants may be unaware of their wage.
A Ratio Utility Billing System, or RUBS, is another possibility. This is a system that divides utility costs based on factors such as the number of people who occupy the unit, the square footage of the unit, the bed/bath ratio of each unit, and other utility usage factors such as the number of water fixtures per unit, the number of gas appliances per unit, and more.

How Does RUBS (ratio utility billing system) Function?
The goal of RUBS is to divide the total utility expense fairly and impartially among all renters. RUBS assigns each utility (e.g., water, gas, electric, etc.) its own unique formula that distributes utility usage among the entire number of tenants in a reasonable manner.
The following factors may be included in the RUBS calculation for a typical rental property:
- Each unit’s square footage.
- The number of available beds and/or baths.
- The quantity of water fixtures.
- The number of people who live in each unit.
- A gas stove, dryer, HVAC system, or fireplace.
The property owner or management can designate a set percentage of the bill to these parameters, distributing the cost fairly based on the occupant’s actual use. Participation in RUBS (ratio utility billing system) is a requirement of the lease. After determining the RUBS distribution percentages and formulas for each utility, the owner can send monthly utility bills to each tenant for their corresponding part.
Tenants are liable for their portion and must pay their dues or risk breaching their lease agreement.
Advantages of Using RUBS (ratio utility billing system)?
- It costs nothing to get started. RUBS does not require an initial monetary investment. It only takes a comprehensive investigation of the property to put it into action.
- All utility costs are covered. If RUBS is properly configured, it will cover 100% of the building’s utility bills, offsetting the tenants’ expenses.
- Submetering costs are avoided. Submetering can be costly. RUBS is an alternate method that eliminates the cost and inconvenience of installing a separate meter for each unit.
- Tenants are discouraged from abusing utilities. Because tenants are billed for the exact quantity of utility usage, RUBS often serves as a deterrent to utility mismanagement.
- Increases the property’s value. Because RUBS balances utility expenses, it enhances the property’s revenue. As a result, the revenue method enhances the overall value of the property.
Disadvantages of RUBS (ratio utility billing system)?
- Current tenants have the right to resist or refuse to comply. Existing tenants may be unwilling to pay potentially higher utility coverage expenses. Initially, implementing RUBS may result in vacancies.
- RUBS (ratio utility billing system) are not permitted in several markets. In some markets, RUBS may be regarded as being unfair to tenants, particularly if the billing system is purely based on square footage and does not take into consideration other criteria. For example, a large square footage apartment may incur a greater utility expense for the tenants, even if the residents are rarely home and use low utility.
CONCLUSION
Overall, RUBS can be a valuable tool for landlords who want to recover the cost of utilities in a fair and accurate way
