What Is RUBS?
What Is RUBS? A Maryland Renter's Guide to Utility Billing Rights
If you rent an apartment in Maryland and your utility charges come from your landlord or property management company rather than directly from a utility provider, you may be part of a billing system you've never heard of, and you may have rights you don't know about.
This guide breaks down what RUBS is, how it works, what Maryland law requires, and what you can do if your landlord hasn't followed the rules.
How Utility Billing Works in Apartment Buildings
Not every apartment handles utilities the same way. In Maryland, there are generally three methods used in multi-family buildings:
Direct billing is the most straightforward. You open an account directly with the utility company — BGE, WSSC, or whoever serves your area — and you pay for exactly what you use. Your landlord isn't involved.
Sub-metering is a step removed. Your building has individual meters installed in each unit, usually managed by a third-party provider who contracts with the landlord. You're still paying based on your own usage, but the billing flows through an intermediary rather than the utility company itself.
RUBS works differently from both. Instead of measuring what each tenant actually uses, the building operates on one or a few master meters. The total cost gets divided among tenants using a formula. That formula might be based on square footage, number of occupants, number of bedrooms, or some other method. But it's not based on your individual consumption.
The result: a tenant who keeps their thermostat low, takes short showers, and turns off every light can end up paying the same, or close to the same, as a neighbor who doesn't.
Why Do Some Buildings Use RUBS?
The short answer is cost. Installing individual sub-meters in an older building means significant construction work: opening walls, running new lines, and retrofitting infrastructure that was never designed for per-unit measurement. For large property management companies managing dozens of older complexes, that investment adds up fast.
So RUBS became the workaround. It lets landlords pass utility costs through to tenants without the expense of sub-metering. Newer buildings are typically constructed with sub-meters from the start, which is why RUBS tends to be concentrated in older apartment stock, particularly in buildings that serve cost-conscious renters.
What Maryland Law Says About RUBS
RUBS itself is legal in Maryland. The state doesn't prohibit landlords from allocating utility costs through a formula. But the law does come with conditions.
Maryland's Tenant Protection Act of 2022 added a section to the Real Property Code (§ 8-212.4) that requires landlords who use RUBS to make a specific set of written disclosures to every prospective tenant before they sign a lease. These aren't suggestions, they're legal requirements.
- A written statement identifying which utilities are billed through the system
- Copies of the last two utility bills they received
- A description of the formula used to calculate each tenant's share, broken down by utility type
- The average monthly bill for all units over the prior calendar year
- Notice of your right to inspect the landlord's billing records
- Disclosure of any additional service charges or administrative fees
- A statement that any billing disputes are between you and the landlord
That's a comprehensive list. And the statute doesn't leave much room for interpretation about what happens if a landlord fails to provide it.
What Happens When Landlords Don't Comply
This is where the law has real teeth. Under § 8-212.4(c)(2), if a landlord fails to provide the required written disclosures, the lease provision requiring the tenant to pay utility charges under RUBS is unenforceable.
That's a critical word. It doesn't mean the charges are reduced. It doesn't mean the landlord gets a second chance to disclose. It means the utility billing provision in your lease has no legal effect, almost as if it were never there.
And if your landlord has been collecting utility payments under an unenforceable provision, that collection may constitute a violation of both the Maryland Consumer Debt Collection Act and Maryland's consumer protection statutes. The argument isn't that you were overcharged. It's that the landlord had no legal right to collect those payments at all.
"No Harm, No Foul" — Why That Defense Doesn't Hold Up
One of the arguments landlords and their attorneys have raised in response to these claims is the idea that tenants weren't actually harmed, that they would have been charged the same amount whether or not the disclosures were provided. It's a common-sense argument on the surface.
But the statute doesn't condition enforceability on harm. It conditions it on disclosure. If the disclosures weren't made, the provision is unenforceable, full stop. The legislature specifically chose the word "unenforceable," and courts generally give that kind of language its plain meaning. Under that framework, even a single dollar collected under an unenforceable provision is a dollar that shouldn't have been collected.

How to Tell If Your Building Uses RUBS
Most tenants don't know whether their building uses RUBS, direct billing, or sub-metering. Here are some signs that RUBS may be in play:
- Your utility charges appear on a statement from your landlord or property management company, not from a utility provider like BGE or WSSC
- You've never opened a utility account in your own name for the unit you rent
- Your utility charges fluctuate in ways that don't match your own usage habits
- You live in an older multi-family building where the landlord handles utilities centrally
If any of those sound familiar, it's worth looking at your lease and any paperwork you received before signing. That's usually where the answer is.
What You Can Do
If you believe your building uses RUBS and you were never provided the written disclosures required by Maryland law, you may have a legal claim. Here's how to start:
Look for language about utility billing, shared meters, or allocation formulas. If you see references to utility charges being calculated by formula rather than by individual usage, that's a strong indicator of RUBS.
Did you receive any written disclosure documents before signing? These should have included prior utility bills, a description of the allocation method, and the other items listed in the statute.
These documents, combined with your lease, are usually enough for an attorney to determine whether RUBS is being used and whether the disclosure requirements were met.
Bienstock Law, LLC and The Law Offices of Ronald S. Canter, LLC are currently reviewing RUBS claims for Maryland tenants at no cost and with no obligation. If you have your lease and utility bills, the review process is straightforward and can often be completed quickly.
Why This Matters Right Now
The RUBS disclosure statute is only a few years old. There is very limited appellate case history, which means this is an evolving area of law. Cases being filed today are among the first of their kind in Maryland.
For tenants, that creates an opportunity. For landlords who haven't been complying, the legal landscape is shifting fast. And with utility costs continuing to rise across the state, more and more renters are starting to ask questions about where their money is going and whether their landlord has the right to collect it.
If you rent in Maryland and your utility charges come through your landlord, it's worth a few minutes to find out where you stand.
