Texas multifamily operators evaluating utility billing services for their properties face a more complex decision than operators in most states. The deregulated electricity market changes the math. So does the fact that most Texas apartments built in the last twenty years are individually metered — which eliminates the entire category of RUBS from the electricity equation.
This is a breakdown of each approach, where each one applies, and why the deregulated market creates an option that most operators in other states have never seen.
RUBS: What It Is and Where It Applies
A ratio utility billing system allocates a master-metered utility cost across residents using a formula. The formula typically uses square footage, number of occupants, number of bedrooms, or some combination. The property receives one utility bill, applies the formula, and invoices each resident for their allocated share.
RUBS works only on master-metered properties. If each unit has its own meter and its own account with the utility or REP, RUBS is not applicable — there is no shared bill to allocate. For electricity specifically, most Texas multifamily built after the mid-1990s is individually metered. RUBS for electricity is largely a legacy arrangement on older stock.
Where RUBS does apply, the tradeoffs are predictable. It's cheaper to implement than submetering because no hardware is required. It produces resident friction because the allocation formula doesn't reflect actual consumption. A resident in a 900-square-foot unit who keeps the thermostat at 78 degrees subsidizes their neighbor in the same unit type who runs at 68. Disputes follow. Texas law under PUCT §25.471 imposes specific disclosure and billing requirements on properties using RUBS arrangements for electricity.
Submetering: Actual Measurement, Higher Costs
Submetering installs individual meters at each unit and bills residents for measured consumption. It's more accurate than RUBS, eliminates the allocation dispute problem, and creates a direct connection between a resident's behavior and their bill.
The cost is the barrier. Installing submeter hardware across a 200-unit property requires capital. Operating the billing system — reading meters, generating invoices, processing payments, handling disputes — requires either internal resources or a third-party utility billing services vendor. Those vendors charge a per-unit monthly fee, which reduces the net recovery.
For water and trash at older master-metered properties, submetering is often the most defensible path. For electricity at individually metered Texas properties, it's largely unnecessary — the utility or REP already handles the metering. The question for those properties is who manages enrollment and whether the property captures any value from the enrollment relationship.
Pass-Through Billing: The Default That Costs Money
In individually metered Texas apartments, the default is pass-through. Residents set up their own electricity accounts with a provider of their choice. They pay that provider directly. The property has no relationship with the chosen provider, no visibility into whether the account was established, and no revenue from the transaction.
When a resident fails to set up their account — which happens — the unit stays on the property's Continuous Service Agreement. The property absorbs the electricity cost until the account transfers. Staff spend time identifying the gap and following up. The accounting logs the cost as an expense.
Pass-through billing feels simple because the property isn't billing anyone. The actual cost is harder to see: gap charges that don't get tracked precisely, staff time that doesn't show up on a P&L line, and a revenue opportunity the property never accesses.
Lease-Synchronized Enrollment: A Different Category
Lease-synchronized enrollment is not a utility billing service in the traditional sense. The property does not bill residents for electricity. Residents pay their retail electricity provider directly, at the same rates they would get shopping independently. Nothing changes for the resident.
What changes is the structure behind the enrollment. Instead of residents choosing providers ad hoc, the property establishes a direct relationship with a retail electricity provider. Enrollment connects to the lease. When a lease is signed, the electricity account activates. When the lease ends, gap coverage holds until the next resident's account begins.
The property earns a commission for every active resident account. It's not a charge passed to residents. It's referral income on the enrollment relationship — a structure in Texas's deregulated market that most property managers have never been set up to access.
This structure requires individual metering per unit, which is why it applies specifically to the Texas market's dominant property type. It doesn't fit RUBS properties. It doesn't require submetering hardware. It uses the metering infrastructure that already exists.
How to Choose the Right Approach
The decision depends on property type and metering configuration.
Master-metered, older stock: RUBS or submetering for electricity and water. If the property is in Texas, PUCT rules apply to any electricity cost recovery arrangement. A utility billing services vendor handles the invoice cycle, but the property still needs to configure the billing correctly to stay compliant.
Individually metered, Texas deregulated market: Pass-through is the floor. Lease-synchronized enrollment with a direct REP relationship is the ceiling. The gap between the two is commission income the property is currently not earning, plus gap charge exposure the property is currently absorbing. Neither is visible unless someone runs the numbers.
For property management companies operating portfolios across Texas, the enrollment structure question applies at scale. A 1,000-unit portfolio with no REP relationship leaves a significant revenue line untouched every month. The setup is a one-time process. After that, it runs without staff involvement — enrollment at lease signing, automatic gap coverage, commission income as a function of occupancy.
If you haven't modeled what that looks like for your portfolio, it's worth doing before the next budget cycle.
Frequently Asked Questions
What are utility billing services for apartments?
Utility billing services for apartments are systems that help property owners manage and recover utility costs from residents. The main approaches are RUBS (ratio utility billing), submetering, pass-through billing, and lease-synchronized enrollment. Each fits different property types and metering configurations. In Texas's deregulated electricity market, lease-synchronized enrollment is a distinct category — it automates resident electricity accounts at move-in and move-out and generates referral income for the property rather than passing costs through to residents.
How do apartments bill for utilities?
Apartments handle utility billing in one of four ways: RUBS allocates a master-metered cost across units by formula; submetering installs individual meters per unit and bills residents for actual consumption; pass-through billing has residents set up and pay providers directly; and direct billing has the property pay and invoice residents. In Texas's deregulated electricity market, most individually metered apartments use pass-through by default — but lease-synchronized enrollment adds a structured property relationship and commission income that pure pass-through does not.
What is the difference between RUBS and submetering?
RUBS allocates a shared utility cost across units using a formula — typically square footage, number of occupants, or both. No individual measurement occurs. Submetering installs individual meters at each unit and bills residents for actual measured consumption. Submetering is more accurate and more defensible in resident disputes, but requires capital investment and an ongoing billing operation. RUBS is cheaper to implement but creates disputes when residents see allocations that don't reflect their actual usage. Neither applies to individually metered properties in Texas's deregulated market, where each unit already has its own account with a retail electricity provider.
Can apartments charge residents for electricity in Texas?
It depends on the metering structure. In individually metered buildings, residents in Texas's deregulated market set up their own retail electricity provider accounts and pay providers directly — the apartment does not charge them for electricity. In master-metered buildings, the property may recover electricity costs through RUBS or direct billing, subject to PUCT rules. Texas property owners who establish a direct relationship with a retail electricity provider can earn referral income on resident accounts without charging residents anything — a structure that is distinct from utility billing and requires no markup on what residents pay.
