Unlocking Value with RUBS: A Utility Billing Solution for CRE Investors

[James Lucenti]

As utility costs rise, commercial real estate (CRE) investors are increasingly turning to smarter, more equitable ways to manage shared expenses—especially in multi-unit properties without individual utility meters. One effective strategy is the Ratio Utility Billing System, or RUBS.

💡 What is RUBS?

RUBS (Ratio Utility Billing System) is a method of allocating utility costs to tenants using a consistent formula when individual metering is not available. It’s often used in older multifamily buildings or mixed-use properties with a single master meter. Rather than including utilities in rent or absorbing the full cost, landlords can fairly allocate these charges—improving the property’s operating income.

🔍 How RUBS Works

RUBS divides total utility costs among tenants based on a predefined metric. Common allocation methods include:

• Equal division among units

• Unit square footage

• Number of occupants

• Number of plumbing fixtures

The goal is to share utility expenses in a manner that is transparent and reasonably reflects each tenant's use.

🧾 Sample Lease Language for RUBS

If you’re considering implementing RUBS at your property, it’s important to have clear lease language. Below is a sample clause that can serve as a reference. However, it’s essential to consult with an attorney to ensure the language complies with local laws and regulations:

RUBS Lease Sample Contract Language
Utility Charges – Gas and Electric (RUBS Allocation)
Tenant acknowledges that the Premises is part of a multi-unit building in which gas and electric service is supplied through a single master meter for all units. As such, individual usage cannot be separately metered. Landlord will allocate the total monthly charges for gas and electric utilities among all tenants using a Ratio Utility Billing System (RUBS).

1. Allocation Method: The monthly gas and electric charges for the entire building shall be allocated equally among the four (4) residential units. Accordingly, Tenant shall be responsible for twenty-five percent (25%) of the total monthly gas and electric bills for the property, regardless of actual usage.

2. Billing and Payment: Landlord or Landlord’s designated billing agent shall issue a monthly utility invoice to Tenant for their share of the gas and electric charges. Payment shall be due within ten (10) days of receipt of the invoice. Failure to pay within the specified timeframe shall constitute a material breach of this Lease and may be subject to late fees as outlined herein.

3. Administrative Fee: Tenant agrees to pay a monthly administrative fee in the amount of $___ to cover the costs of processing and administering utility billing under the RUBS system.

4. Disputes: Any disputes regarding utility charges must be submitted to Landlord in writing within fifteen (15) days of receipt of the invoice. During the resolution of any dispute, Tenant must pay the undisputed portion of the utility charges in a timely manner.

5. No Withholding of Rent: Tenant shall not withhold rent or deduct utility charges from rent payments under any circumstances, regardless of disputes related to utility billing.
