The Benefits of Submetering for Multifamily Properties
Key Takeaways
- Submetered properties hit 85-95%+ cost recovery compared to 70-85% for RUBS and 0% for utilities rolled into rent.
- The EPA's WaterSense program documents 15-40% consumption reduction in submetered multifamily — price signals change behavior overnight.
- A 300-unit example shows a 1.8-year payback and $546,000 in 10-year net benefit when recovery and conservation stack.
- Water comes first, electric next for properties with individual HVAC — sewer usually rides on the water meter.
- Residents push back against unfair charges, not fair ones; the transition communication matters more than the billing method.
Master-metered multifamily properties have a structural problem: the property pays the utility bill, but the residents consume the utilities. Without individual measurement, there's no accountability, no conservation incentive, and no way to accurately recover costs.
Submetering solves all three.
By installing individual meters on each unit, you measure actual consumption, bill residents for what they use, and create the price signal that drives conservation. The result: higher recovery rates, lower consumption, better resident fairness, and a direct improvement to NOI.
In our RUBS vs. Submetering comparison, we covered the trade-offs between the two main billing methods. This post goes deeper on why submetering specifically makes sense for multifamily operators.
The Financial Case
Higher Recovery Rates
Submetered properties consistently achieve 85-95%+ cost recovery, compared to 70-85% for RUBS and 0% for properties that include utilities in rent.
For a 300-unit property spending $180,000/year on water and sewer:
- No billing: $0 recovered (property absorbs 100%)
- RUBS at 80% recovery: $144,000 recovered ($36,000 absorbed)
- Submetering at 92% recovery: $165,600 recovered ($14,400 absorbed)
The difference between RUBS and submetering alone is $21,600/year — before accounting for the conservation effect.
Consumption Reduction
This is the stat that changes the math. The EPA's WaterSense program documents that submetering reduces water consumption by 15-40% in multifamily properties. When residents pay for what they use, they use less.
Applying a conservative 25% reduction to that $180,000 water bill:
- New annual cost: $135,000
- Annual savings from conservation alone: $45,000
The ROI Math
| 300-Unit Property Example | |
|---|---|
| Submeter installation cost | $120,000 (at $400/unit) |
| Annual conservation savings | $45,000 |
| Annual recovery improvement (vs RUBS) | $21,600 |
| Total annual benefit | $66,600 |
| Payback period | 1.8 years |
| 10-year net benefit | $546,000 |
Improved Cash Flow
With RUBS, billing cycles often lag because you're waiting for the master bill before you can calculate allocations. With submetering, you have real-time consumption data and can bill on your schedule. Faster billing means faster collection and improved cash flow.
The Operational Case
Resident Fairness
The #1 complaint about RUBS is fairness — conservation-minded residents subsidize high-usage neighbors. Submetering eliminates this entirely. Each resident pays for exactly what they consume. Fair billing means fewer disputes, fewer complaints, and higher resident satisfaction.
Data Visibility
Submeters generate consumption data that enables:
- Leak detection — a unit with sustained high consumption likely has a running toilet or dripping faucet
- Anomaly alerting — sudden spikes flag issues before they become costly
- Benchmarking — compare consumption across similar units to identify outliers
- Trend analysis — track consumption patterns over time to inform capital planning
This data feeds directly into billing strategy optimization and helps operators find the hidden revenue in their billing operation.
Regulatory Positioning
As we track in our 2026 Compliance Guide, the regulatory trend strongly favors measurement over estimation. Submetering positions you ahead of compliance requirements:
- Ohio's HB 173 would place submetering companies under PUCO oversight — but measurement-based billing is what regulators prefer
- States restricting RUBS push operators toward submetering as the compliant alternative
- Record-keeping requirements are easier to meet when you have actual meter data vs. allocation formulas
What to Submeter First
Not every utility needs submetering simultaneously. Prioritize by ROI:
Common Concerns (and Reality)
"The installation cost is too high"
At $200-600/unit, it's a real capital expenditure. But with payback periods of 2-3 years and benefits that continue indefinitely, it's one of the highest-ROI capital investments a property can make. Many operators finance submeter installations through the utility savings themselves.
"We'll disrupt residents during installation"
A professional installation team can install water submeters with minimal disruption — typically a few hours of water shutoff per building. Electric meter installation often requires no unit access at all (CTs are installed at the electrical panel). See our guide to professional submetering services for what to expect.
"Our property is old and the plumbing won't work"
Some older properties have plumbing configurations (shared risers, inaccessible pipes) that make water submetering impractical. In those cases, RUBS is the right interim solution. But electric submetering is almost always feasible regardless of building age.
"Residents will push back"
Residents push back against unfair charges, not fair ones. When you show residents that submetering means they only pay for what they use — and that conservation directly lowers their bill — most respond positively. The transition communication matters more than the billing method.

Talk to the TeamGetting Started
If you're considering submetering for your multifamily portfolio:
- Assess your properties. Which ones have the highest utility costs and the most units? Start there for maximum ROI.
- Choose your utility priority. Water first for most properties. Electric if units have individual HVAC.
- Get a site assessment. A professional provider will evaluate your plumbing/electrical and recommend the right meters. See our meter solutions page for what we offer.
- Plan the billing transition. If you're currently on RUBS, plan for a parallel billing period. If you're not billing at all, submetering is the path to immediate recovery.
- Budget for the long term. Include ongoing maintenance in your projections — not just installation.
The operators who submeter their properties recover more, spend less on utilities, and have the data to prove it. The ones who don't are leaving money on the table every month.
