Is RUBS legal? Ratio utility billing by state, 2026

Key Takeaways

• Whether RUBS is legal is not a single national answer. It is banned outright in Connecticut and North Carolina, banned locally in West Hollywood and San Jose, tightly regulated in California, and subject to a new Colorado disclosure law (HB25-1090) effective January 1, 2026, whose application to RUBS specifically remains legally unsettled.

• 2026 is an active regulatory moment for RUBS, not a settled one. Seattle has an organized tenant campaign pushing for a citywide ban as of April 2026, and Washington State's new rent stabilization law creates unresolved questions about how RUBS charges interact with the state's rent increase caps.

• RUBS allocates a building's master utility bill across units using a formula based on factors like square footage, occupant count, or bedroom count, not actual individual metering, which is the specific mechanic driving the current transparency and fairness objections.

• Where RUBS is legal, PM companies typically recover 13% to 18% of utility expenses on average through the combination of cost recovery and the conservation incentive it creates, according to industry benchmarking.

• Regardless of which state a property is in, clear lease disclosure of the RUBS formula, the billing methodology, and the resident's right to request supporting documentation is now treated as a baseline expectation, not an optional best practice.

A multifamily property switches from a flat utility fee to a ratio utility billing system in 2024, and by early 2026 that decision has become the subject of an organized tenant campaign, a city council hearing, and national news coverage. RUBS is not a settled, boilerplate line item anymore in several major markets. It is an actively contested regulatory question, and the answer to "is this legal" depends entirely on which state and sometimes which city the property sits in.

Numetix takes an expert-led, AI-powered, and human-in-the-loop approach to utility billing setup, confirming the current legal status for a property's specific jurisdiction before any RUBS structure goes live, not after a tenant complaint arrives. This guide covers what RUBS actually is, where it stands legally right now, and how to account for it correctly where it remains permitted.

Quick Answer: What is a ratio utility billing system, and is it legal?

• A ratio utility billing system (RUBS) divides a property's total master utility bill among individual units using a formula, most commonly based on square footage, occupant count, or bedroom count, rather than individual submeters measuring actual usage.

• Legality varies sharply by jurisdiction. It is banned statewide in Connecticut and North Carolina, banned locally in cities including West Hollywood and San Jose, heavily regulated in California, and newly subject to Colorado's junk-fee disclosure law (HB25-1090) as of January 1, 2026, with the RUBS-specific application still legally contested.

• Where RUBS remains legal, most jurisdictions require clear, written lease disclosure of the exact formula used and the underlying methodology, and several increasingly require this disclosure regardless of whether a specific ban exists.

What RUBS actually is, mechanically

Ratio utility billing system (RUBS) allocates a building's total, unmetered utility bill (commonly water, sewer, and trash, sometimes gas or electric in common areas) across individual units using a formula rather than direct measurement. Common formulas use square footage as a percentage of total leasable space, number of occupants per unit, or number of bedrooms. RUBS exists as an alternative to submetering, which requires physical meter installation on every unit and carries a substantially higher upfront capital cost and a months-to-years implementation timeline. RUBS can typically be implemented in weeks using existing billing infrastructure.

Why RUBS is a live regulatory fight in 2026, not settled reference material

The core objection driving 2026's regulatory activity is that RUBS estimates usage rather than measuring it, which tenant advocates argue allows landlords to increase effective housing costs while circumventing rent increase caps in rent-controlled or rent-stabilized markets. Seattle's tenant coalition, organizing since mid-2025 under the name Seattle Ban RUBS, escalated to a formal city council push by April 2026, with the Seattle Renters' Commission formally recommending a ban. Washington State's newly passed rent stabilization law caps annual increases at 7% plus inflation or 10%, whichever is lower, and it remains legally unclear whether RUBS charges count toward that cap, which is precisely the ambiguity tenant advocates argue landlords are exploiting. Colorado's HB25-1090, a broader junk-fee and disclosure law effective January 1, 2026, does not explicitly name RUBS, and legal analysis from Colorado practitioners describes two competing interpretations of whether it applies, with no definitive court ruling yet.

Where RUBS stands by jurisdiction

Connecticut and North Carolina prohibit RUBS for residential multifamily entirely; submetering or absorbing the cost as a operating expense are the only compliant alternatives in those states. California permits RUBS but regulates it tightly, and several California cities including West Hollywood and San Jose have banned it locally regardless of the statewide framework. Arizona and Nevada currently allow RUBS without significant restriction. Massachusetts restricts it. Colorado's status is legally unsettled as of the 2026 effective date of HB25-1090. This list changes as litigation and legislation develop; confirm the current status for a specific property's exact city and state before implementing or continuing a RUBS program, not just the state-level headline rule.

How to account for RUBS revenue and expense correctly where it remains legal

RUBS collections should be recorded as a distinct revenue line, separate from base rent, since it represents a specific cost recovery rather than rental income and owners frequently want this visibility for NOI and expense-ratio reporting. The underlying master utility expense continues to be recorded as a standard operating expense; RUBS revenue partially or fully offsets it rather than replacing the expense entry. This separation also matters for jurisdictions with rent-increase caps, since regulators and courts distinguishing RUBS charges from rent increases generally rely on exactly this kind of clean revenue-line separation as evidence the charge is a genuine cost recovery, not a disguised rent increase.

Frequently asked questions

What is the difference between RUBS and submetering?

Submetering installs individual meters on each unit, measuring actual usage directly, and bills each tenant based on their real consumption. RUBS estimates usage using a formula (square footage, occupancy, or bedroom count) applied to the building's total master bill, without measuring individual consumption at all. Submetering is more accurate and generally faces fewer legal challenges, but requires significant capital investment and a longer implementation timeline than RUBS.

Can a PM company switch from RUBS to submetering mid-lease?

Most leases require advance written notice before changing the utility billing method, and some jurisdictions specify a minimum notice period or require the change to align with lease renewal rather than taking effect mid-term. Given the current regulatory volatility around RUBS in several markets, a mid-lease switch to submetering, properly noticed, can reduce ongoing legal exposure in jurisdictions where RUBS faces active challenge, but should be evaluated against the capital cost of submeter installation.

Does RUBS ever count as a violation of rent control or rent stabilization limits?

This is precisely the unsettled question driving much of the 2026 regulatory activity. In jurisdictions with rent increase caps, whether a RUBS charge (or an increase in RUBS charges) counts toward that cap depends on the specific statute's definition of rent and has not been uniformly resolved. Washington State's rent stabilization law and Colorado's HB25-1090 both leave this ambiguous as of their 2026 effective dates. PM companies operating in rent-controlled or rent-stabilized markets should treat this as an open legal question requiring case-specific counsel, not an assumed answer either way.
