At Coastline Equity, we believe that fair and transparent utility billing is essential. That is why many of our multi-tenant properties use RUBS, or the Ratio Utility Billing System, to allocate shared utility costs in a way that reflects real usage and household size.
Whether you are new to RUBS or just want to better understand your bill, here is everything you need to know.
RUBS is a utility billing method that divides the cost of shared services among residents based on measurable factors. Instead of relying on individual meters, which can be costly to install and maintain, RUBS uses a standardized formula that considers:
Number of occupants
Overall building characteristics
Water and sewer
Trash and recycling
Gas and electricity (if shared)
Common area utility usage
This approach is especially effective in properties that were not originally built with individual metering infrastructure.
At Coastline Equity, we use a straightforward and fair approach to RUBS billing. Our standard formula divides utility costs using:
50% based on the number of occupants in each unit
50% based on the square footage of each unit
This hybrid model balances two key factors that influence utility usage:
Occupancy reflects actual human activity, such as how often water is used, how many showers are taken, and how much electricity is consumed.
Square footage accounts for heating, cooling, and lighting needs, which scale with the size of the space.
By combining both elements equally, we ensure that utility charges are more accurately and fairly distributed across all residents.
If your building has unique characteristics, we may adjust this formula slightly, but our goal is always to use the fairest and most consistent method available.
RUBS ensures each household pays a fair share based on expected consumption. Residents who use more utilities contribute more, while those who use less avoid subsidizing others.
Installing individual utility meters can be expensive and time-consuming. RUBS reduces those upfront and ongoing costs, allowing property managers to maintain more affordable housing.
When residents see direct utility charges, they are more likely to monitor usage. Over time, this leads to lower consumption and benefits both the environment and residents' budgets.
Each Coastline Equity property uses a custom RUBS formula tailored to the specifics of that building. These formulas typically account for:
Unit Square Footage: Larger units are assumed to use more utilities.
Number of Occupants: More people generally means higher usage.
Seasonal and Operational Variables: Building age, efficiency, climate, and shared facilities are all factored into the allocation model.
The goal is to distribute costs fairly while remaining compliant with local utility billing regulations.
While RUBS does not track individual usage directly, it relies on logical indicators like unit size and occupancy. This ensures that billing is balanced across the building, without requiring expensive metering systems.
Yes. If you believe your RUBS bill is incorrect, please contact your property manager. We will review the charges with you and make any necessary corrections.
No. RUBS charges are billed separately and appear as a distinct line item on your monthly statement. They are not part of your base rent.
Yes. Lease agreements at RUBS-enabled properties include clear language explaining the billing process and how your utility share is calculated.
Our billing formulas are designed using property data, industry best practices, and local compliance requirements. We routinely review them for accuracy and fairness.
RUBS applies to the household unit, not individual tenants. You and your roommates should determine how to divide utility costs among yourselves.
Even in a shared billing system, your usage habits matter. Consider these steps to help manage your utility costs:
Fix leaky faucets quickly
Take shorter showers
Run dishwashers and washing machines only when full
Turn off lights and electronics when not in use
Use energy-efficient appliances and bulbs
Keep blinds closed during hot weather to reduce cooling needs
Recycle and compost when possible
Avoid unnecessary packaging
Dispose of trash properly to help manage common area waste costs
At Coastline Equity, we are committed to fair billing practices and clear communication.
