Utility billing in multifamily apartments is a system where tenants pay for utilities based on their usage instead of having costs included in rent. This approach helps property managers control expenses and encourages tenants to use resources wisely. Here’s what you need to know:
- Why It Matters: Charging tenants for their actual usage can reduce energy consumption by up to 35% and lower property expenses. It also promotes fairness, as tenants only pay for what they use.
- Challenges: Legal compliance, older buildings without individual meters, and administrative workload can complicate utility billing for large complexes with 300+ units.
- Billing Methods:
- RUBS (Ratio Utility Billing System): Divides costs based on unit size, occupants, or fixtures.
- Submetering: Tracks actual consumption with individual meters.
- Flat Fees: Charges a fixed amount regardless of usage.
- All-Inclusive Rent: Bundles utilities into rent payments.
- Regulations: State rules vary, with some requiring submeters in new buildings or transparency in billing practices. Non-compliance can lead to fines or lawsuits.
The right method depends on your building’s setup, tenant preferences, and budget. Submetering is precise but costly, while RUBS is easier to implement. Flat fees and all-inclusive models prioritize simplicity but don’t encourage conservation.
For property managers, balancing cost recovery, tenant satisfaction, and legal compliance is key to effective utility billing.
Sub-metering and RUBS for Multifamily Real Estate: How to Decrease Expenses & Increase NOI
4 Main Utility Billing Methods
Property managers have four primary ways to split utility costs among residents in multifamily communities. Each method comes with its own set of benefits and drawbacks, making the right choice heavily dependent on factors like the building’s infrastructure, budget considerations, and what tenants expect.
Ratio Utility Billing System (RUBS)
RUBS divides utility costs using a formula based on factors like unit size, the number of occupants, and even the number of bedrooms or bathrooms [3]. Instead of measuring actual consumption, it spreads the total utility bill across all units proportionally. For instance, a two-bedroom apartment with more residents might get a larger share of the water bill than a studio with one occupant. Similarly, square footage can determine electricity costs, while water and sewer charges might be influenced by the number of fixtures.
The appeal of RUBS lies in its affordability and ease of setup [3]. Property managers can implement it without making major changes to the building, avoiding construction headaches and keeping administration simple.
Interestingly, studies have shown that RUBS can cut water and utility usage by anywhere from 5% to 27% [5], with total utility consumption reductions reaching up to 40% in some cases [6]. However, because it doesn’t track actual usage, it’s less precise than other methods like submetering. For example, a tenant who’s rarely home might pay the same as someone who’s there all the time. Additionally, some states don’t allow RUBS [2], so checking local laws is crucial before moving forward.
Submetering
Submetering takes a more precise approach by installing individual meters for each unit to measure actual utility usage [3]. This method ensures residents pay only for what they consume, promoting fairness and encouraging conservation. It eliminates the issue of one tenant subsidizing another’s utility habits.
Operationally, submetering has some great perks. It allows property managers to quickly spot leaks, track unusual usage, and collect data to support energy-saving initiatives. Another major advantage is that it ensures every unit’s consumption is accounted for, enabling full cost recovery. However, the upfront investment isn’t small - submeters cost between $200 and $400 each, so outfitting a 300-unit building could run $60,000 to $120,000, plus labor. Ongoing maintenance and staff to analyze the data also add to the expenses [7].
The ease of installation depends largely on the building’s age and design. Newer buildings generally accommodate submetering more easily, while older ones may require extensive retrofitting.
Flat Fees
Flat fees simplify utility billing by charging tenants a fixed monthly amount that’s added to their rent [4]. This straightforward approach eliminates the need for complex calculations and shields tenants from seasonal variations or unexpected spikes in utility costs.
While flat fees are easy to manage, they don’t reflect actual usage, which can lead to inequities. Higher-usage tenants may benefit, while those who use less end up paying more than their fair share.
All-Inclusive Rent Models
With all-inclusive rent, utility costs are bundled into the monthly rent payment [4]. Tenants love the simplicity of a single, consistent payment, making it easier to budget without worrying about surprise utility bills. In competitive rental markets, this "no hidden fees" approach can be a selling point.
For property managers, this model removes the hassle of separate utility billing and can cut down on disputes over usage. It’s especially common in areas where utilities like heat, water, and sewer are traditionally included in rent for larger buildings [2]. However, this convenience comes with risks. If utility rates rise, the property’s profitability can take a hit. Plus, without usage-based billing, tenants have little incentive to conserve energy. Research shows that properties where landlords cover all utilities can see energy consumption increase by as much as 26% [1].
Comparing the Methods
Here’s a quick breakdown of how these billing methods stack up:
| Method | Cost Allocation | Accuracy | Tenant Control | Implementation Complexity |
|---|---|---|---|---|
| RUBS | Formula-based | Moderate | Limited | Low |
| Submetering | Actual usage | High | High | High |
| Flat Fees | Fixed amount | Low | None | Low |
| All-Inclusive | Bundled in rent | Low | None | Low |
Choosing the right method depends on the building’s layout, financial strategy, and tenant preferences. RUBS is often the go-to for older buildings where individual meters are too expensive to install [5]. Submetering, on the other hand, makes sense for newer properties where the investment can be justified. Flat fees and all-inclusive models work well when simplicity is the priority and utility rates are relatively stable.
Regulations and Compliance Requirements
Utility billing in multifamily housing comes with a maze of federal, state, and local rules. Property managers need to navigate these regulations carefully to avoid fines, legal troubles, and operational disruptions.
Key U.S. Regulations
Utility billing rules vary widely across the United States. Some states enforce strict mandates, while others take a more relaxed approach. For instance, California mandates submeters in all new multifamily buildings as of January 1, 2018. This ensures tenants are billed based on their actual utility use, encouraging conservation efforts [8][9].
In New York City, Local Law 88 requires submetering for buildings over 50,000 square feet and tenant spaces exceeding 10,000 square feet. The deadline for compliance is January 1, 2025, with the aim of promoting energy efficiency and holding tenants accountable for their usage [8].
Other states have introduced targeted measures. Georgia, under the 2010 Water Stewardship Act, requires submeters in new residential, retail, and light industrial buildings permitted after July 1, 2012. Tenants must be billed based on their water and wastewater use [9]. Similarly, Washington mandates hot water submetering in multifamily buildings, while Seattle enforces submetering for buildings over 20,000 square feet or tenant spaces larger than 2,500 square feet [8][9].
Beyond installation requirements, many states demand transparency in billing practices. For example, landlords may recover administrative costs tied to submetering, but these fees must be clearly disclosed to tenants. Meter accuracy standards and dispute resolution processes are also common regulatory requirements.
| State | Submetering Regulations |
|---|---|
| Arizona | Allows submeters for utilities like gas, water, electricity, trash removal, and wastewater [8] |
| California | Requires submeters in new multifamily residential buildings as of January 1, 2018 [9] |
| Connecticut | Permits submetering in specific cases, such as buildings using renewable energy or combined heat systems [8] |
| District of Columbia | Allows submetering if outlined in the rental agreement or lease [8] |
| Florida | Permits submetering for residential and commercial properties [8] |
| Georgia | Mandates water submetering for new multi-unit residential and certain other buildings permitted after July 1, 2012 [8] |
| Maryland | Requires submeters for gas and electricity in residential units in apartment houses, offices, or shopping centers [9] |
| New York | Allows submetering across residential, commercial, industrial, and government-owned properties [8] |
| Washington | Mandates hot water submetering in multifamily buildings [9] |
Fee transparency is another area where states are tightening rules. For example, Colorado HB25-1090, effective January 1, 2026, requires landlords to advertise rental units with all mandatory fees included in a single, prominent total price. It also caps utility markups at 2% or $10 per month [11]. Similarly, Massachusetts will, starting September 2, 2025, require landlords to clearly present total rental costs, including all fees, in advertisements [11].
Virginia HB 2430, effective July 1, 2025, mandates itemized charge disclosures on lease agreements, while Nevada AB 280 requires a detailed appendix of mandatory and optional fees. For variable fees, landlords must disclose actual costs, and fixed fees must reflect current rates. Any undisclosed fees are prohibited [11].
Proposed legislation like California AB 1248 could further reshape the landscape. If passed, it would require certain charges - like trash or pest control fees - to be included in rent, with steep penalties for non-compliance [11]. Staying informed about such changes is critical when determining the most compliant billing methods.
Penalties for Non-Compliance
Ignoring these regulations can result in severe consequences. Penalties range from fines and lawsuits to, in extreme cases, property shutdowns. Legal disputes can quickly rack up costs, while financial penalties can strain cash flow [12][13]. In some instances, violations may even lead to the loss of a real estate license [13].
Fair housing violations are another significant risk, carrying heavy fines and potential legal action. These issues can tarnish a property manager's reputation and disrupt operations [13]. Adding to the complexity, rising insurance costs have left 61% of multifamily property owners facing higher deductibles [12].
Nicole Upano, Assistant Vice President of Housing Policy and Regulatory Affairs at the National Apartment Association, highlights the importance of staying proactive:
"We have been very actively engaged in federal regulatory advocacy in response to the White House blueprint for the Renters' Bill of Rights" [10].
Celeste Rivas from Residential Rentals underscores the broader implications of compliance:
"Following relevant laws is not simply about avoiding fines; it is the only way to maintain tenant safety, protect your assets and reputation, and ensure smooth operations." [12]
To mitigate risks, property managers should regularly audit their compliance practices, identifying and addressing any gaps before they escalate. Training staff on safety protocols, legal requirements, and tenant rights is equally essential. Subscribing to industry newsletters, joining professional associations, and using regulatory update services can help property managers stay ahead of evolving regulations [12].
With the regulatory environment changing rapidly, staying vigilant is no longer optional - it's a necessity for successful property management [13].
How to Keep Tenants Informed
After outlining billing methods and regulatory requirements, maintaining open communication with tenants is essential for smooth operations. Transparent utility billing not only builds trust but also helps reduce disputes. When tenants clearly understand how their charges are calculated, they’re more likely to accept their bills without hesitation.
Explaining Billing Methods to Tenants
A good starting point for effective utility billing is providing clear explanations upfront - ideally during the lease signing process. Don’t wait until the first bill arrives to explain how charges are calculated. Whether you use a Ratio Utility Billing System (RUBS), submetering, flat fees, or an all-inclusive rent model, make sure tenants understand the system. For example, if you’re using RUBS, explain how factors like unit size or the number of occupants determine each tenant’s share of the total utility cost.
Be thorough - include details about the calculation method, billing cycle, and any administrative fees in the lease agreement or as part of a utility billing addendum. Highlighting the conservation benefits of the system can also help tenants see how responsible usage might lead to lower overall costs.
Creating Clear Billing Statements
Well-organized and detailed billing statements go a long way in preventing confusion. Break down the total utility costs for the billing period and clearly show how each tenant’s portion was calculated. Including historical data can help tenants track their usage trends and understand any changes in their bills.
If administrative fees are part of the charges, list them separately from the utility costs. For submetered units, consider including actual meter readings - both previous and current - along with the rate calculation. This level of transparency provides tenants with all the details they need to verify their bills, minimizing disputes and misunderstandings.
Resolving Tenant Disputes
Even with clear communication, disputes about utility bills can still happen. When they do, addressing them promptly is key to maintaining trust. Aim to respond to tenant inquiries within 24 to 48 hours, and use a standardized process to document and resolve disputes. If an error occurs - like a miscalculation or overcharge - correct it immediately and explain the issue to the tenant.
To further improve communication, train staff to handle billing questions professionally and provide additional resources, such as an FAQ document covering common billing topics. These efforts can help ensure tenants feel heard and valued, reinforcing a positive relationship between management and residents.

Common Property Manager Problems
Beyond the challenges tied to billing methods and regulatory requirements, property managers often encounter additional obstacles when implementing utility billing systems in large multifamily communities. These issues can disrupt operations and affect tenant satisfaction, making it crucial to address them effectively.
Dealing with Changing Utility Rates
Fluctuating utility rates can be a headache for property managers, making it tough to predict monthly expenses and, in turn, impacting a property's net operating income (NOI). For instance, a 12.8% rate hike could add over $30 a month to utility costs, with Tier 1 electricity rates jumping from 34.1 to 42 cents per kWh - potentially increasing some bills by $69[17].
To navigate these challenges, property managers can take a few proactive steps:
- Conduct regular rate audits to catch billing errors and inefficiencies[15].
- Negotiate fixed-rate energy plans with utility providers to avoid sudden price spikes and ensure more consistent budgeting[16].
- Implement energy-efficient upgrades, such as LED lighting and smart thermostats, and participate in demand response programs to lower consumption and stabilize costs.
These strategies not only help manage fluctuating rates but also address broader concerns, like outdated infrastructure in older buildings.
Adding Submeters to Older Buildings
Retrofitting older properties with submeters can be both technically and financially demanding[19]. Many buildings built before the 1990s lack the necessary infrastructure for individual unit metering due to shared risers or outdated electrical systems.
To tackle these challenges, property managers can explore financing options, including:
- Energy service agreements
- Multifamily green loans from Fannie Mae, Freddie Mac, or the FHA
- State rebate programs[18]
Advancements in modular wireless submetering now allow for installation with minimal modifications, making the process more feasible[19].
Before diving into submetering, it’s essential to assess the building’s existing utility setup. Properties where each unit has its own riser are typically better suited for submetering, making it a more cost-effective choice. For buildings where full submetering isn’t practical, a RUBS (Ratio Utility Billing System) can be a viable alternative. Rolling out these systems in phases can also help minimize tenant disruptions[19]. However, technical upgrades aren’t the only hurdle - tenant concerns also need to be addressed thoughtfully.
Managing Tenant Perception Issues
Tenant concerns often arise when utility billing methods seem unfair or unclear. Addressing these worries requires clear and transparent communication. Property managers should explain how the billing system works and highlight the benefits of conservation. For example, studies show that RUBS can cut water and utility usage by 5% to 27%[5], while fair billing practices can reduce overall utility consumption by 5–10% or more[20].
Providing detailed billing statements is another key step. Breaking down charges - such as usage, unit size, and shared area contributions - helps tenants understand their responsibilities and builds trust[21]. Educational initiatives can further empower residents by showing them how their consumption impacts their bills and offering practical tips to save water and energy.
Lastly, having a clear dispute resolution process in place is crucial. Property managers should respond promptly to tenant concerns, perform regular meter calibrations, and conduct system audits to ensure accuracy. These measures not only resolve disputes but also reinforce the property’s commitment to fairness and transparency.
Side-by-Side Comparison of Billing Methods
To build on the earlier discussion of operational and regulatory challenges, here's a detailed comparison of how different utility billing methods affect key performance factors. Deciding which method best suits your multifamily property depends on balancing these factors with your unique needs.
Comparison Table
| Factor | RUBS | Submetering | Flat Fees | All-Inclusive Rent |
|---|---|---|---|---|
| Implementation Speed | Fast – can be set up quickly [4] | Slower due to required meter installation | Fast – ready to go immediately | Fast – included in lease terms |
| Upfront Costs | Minimal [22] | $550–$900 per unit [22] | None | None |
| Accuracy | Moderate – relies on allocation formulas | High – measures exact consumption | Low – fixed charge regardless of usage | Low – no tracking of usage |
| Administrative Burden | Low to moderate | High – involves ongoing meter maintenance | Very low | Very low |
| Tenant Conservation Incentive | Moderate | High – ties directly to usage | None | None |
| Utility Cost Reduction | 20% decrease in owner costs [22] | Varies depending on conservation | None | Predictable budgeting only |
| Usage Reduction Potential | 5% to 27% reduction [14] | Significant potential | None | Usage may increase |
| Ongoing Fees | Minimal | Up to $4.75 or 25% of billed amount [23] | None | Included in rent |
This table highlights the strengths and weaknesses of each billing approach, helping you weigh the trade-offs. For example, RUBS strikes a balance between cost savings and ease of implementation. As David Bitton, Co-founder of DoorLoop, explains:
"RUBS is also fast to implement, so you and your tenants can start saving money through its adoption quickly." [4]
Submetering, on the other hand, offers unmatched accuracy but comes with higher upfront costs. For larger properties - like those with 300+ units - installation costs can surpass $225,000, based on an average of $750 per unit [2]. However, the precision of individual metering often makes the investment worthwhile in newer buildings designed for such systems.
Flat fees and all-inclusive rent models prioritize simplicity but lack incentives for conservation. These methods can be practical in markets with frequent tenant turnover or where predictable monthly costs are more appealing than usage-based billing.
The right choice depends on your building's layout, budget, and operational goals. Before deciding, consider conducting an energy assessment to better understand your property's specific needs [2].
Conclusion
Key Takeaways
Choosing the best utility billing method for your multifamily property involves balancing cost, accuracy, and the impact on your tenants. Each option has its own strengths and trade-offs, which can directly affect your bottom line and tenant satisfaction.
- RUBS (Ratio Utility Billing System) offers a practical mix of cost efficiency and quick implementation. With little upfront investment and the potential to cut utility usage by 5% to 27% [5], it’s a fair alternative when submetering isn’t an option [4]. However, its reliance on allocation formulas rather than precise usage measurements means it may not be the most accurate.
- Submetering delivers unmatched accuracy and encourages conservation, but it comes with a higher initial cost. For properties - especially newer ones - designed to accommodate individual meters, this precision often justifies the investment.
- Flat fees and all-inclusive rent focus on simplicity rather than conservation. While they ease administrative tasks, they don’t motivate tenants to reduce their utility consumption and may even lead to higher usage.
Navigating local regulations is another critical factor. Utility billing rules are becoming more stringent, and staying up-to-date can help property managers avoid fines and legal complications [25]. Regularly reviewing regulatory updates and potentially working with specialized utility billing providers can ensure accuracy and compliance [25].
Finally, transparency is essential. When tenants clearly understand what they’re being billed for, it fosters trust and improves overall satisfaction [24].
These points provide a foundation for making an informed decision.
Final Thoughts
Your choice of utility billing method should reflect your property’s infrastructure, budget, and tenant preferences. For larger properties with 300 or more units, scalability and administrative complexity become even more important, highlighting the need for a tailored approach.
Before deciding, take a close look at your property’s energy profile. Utility expenses often rank among the largest operational costs for property managers [26], making this decision a critical factor in overall financial performance.
FAQs
What should property managers consider when selecting a utility billing method for a large multifamily apartment complex?
When deciding on a utility billing method for a large multifamily apartment complex, there are several important factors property managers need to weigh.
Infrastructure plays a major role. Submetering, for instance, offers precise tracking of each unit's utility usage, but it comes with higher upfront installation costs. On the other hand, RUBS (Ratio Utility Billing System) is a budget-friendly alternative that divides utility costs based on factors like unit size or the number of occupants.
Regulatory compliance is another key consideration. State laws often set rules around billing practices, cost recovery limits, and the level of transparency required. Ensuring your method aligns with these regulations is non-negotiable.
It’s also worth considering tenant preferences and the value of clear communication. Transparent billing - whether through detailed usage breakdowns or steady flat fees - can go a long way in keeping tenants happy.
Lastly, assess how easy the system is to implement and maintain. Look at potential hurdles like ensuring billing accuracy or managing customer service issues. By carefully balancing these factors, you can choose a billing approach that fits your property’s needs while keeping both tenants and compliance in mind.
How do state regulations affect the way utility billing systems are implemented in multifamily apartments?
State regulations have a big influence on how utility billing systems operate in multifamily apartment communities. These laws are designed to ensure fair and transparent billing, often requiring detailed energy usage reports and banning hidden fees. For instance, some states insist on submetering or specific billing disclosures, while others control how charges are calculated and restrict certain billing methods.
On top of that, many states have tenant protection rules in place. These can include limits on disconnection practices and strict oversight of billing standards. For property managers, keeping up with local regulations is a must. These rules can differ greatly from state to state, and staying informed is key to maintaining clear billing practices and avoiding legal complications.
How can property managers clearly explain utility billing to tenants and handle disputes effectively?
Building Trust Through Clear Utility Billing Practices
Property managers can strengthen tenant relationships by offering straightforward explanations of utility billing methods. Whether it's RUBS (Ratio Utility Billing System), submetering, flat fees, or inclusive rent, take the time to explain how charges are calculated. Providing this information in writing - especially during lease signings or tenant onboarding - can go a long way in reducing misunderstandings. A quick refresher through regular updates or reminders can also help keep everyone on the same page.
When disputes come up, prioritize open communication and fairness. Hear out tenant concerns, keep detailed records of all interactions, and refer back to the lease agreement or established billing policies to address issues. By having clear policies in place and resolving concerns quickly, you not only build trust but also ensure compliance with local regulations.
