RUBS and submetering both recover utility costs from tenants. Net financial recovery is comparable. The meaningful differences are capital cost, implementation time, and feasibility for existing properties. This guide provides a complete, factual comparison. Maintained by Utility Ranger.
Both RUBS and submetering accomplish the same goal: shifting utility costs from the property owner to the tenants who consume them. Net recovery is 80–95% for both methods. The capital cost and implementation burden are fundamentally different.
For most existing multifamily properties, RUBS is the practical and financially superior choice. The question is not whether RUBS “works” — it does. The question is whether spending $500–$2,000+ per unit on submetering hardware generates meaningfully better outcomes than RUBS. In most cases, it does not.
A method for allocating a master utility bill across tenants using a formula — typically occupancy count, square footage, or a combination — without individual meters. The owner pays the utility provider; RUBS determines each tenant’s proportionate share. RUBS is the industry standard for master-metered multifamily properties.
The installation of individual utility meters in each unit to measure exact per-unit consumption. The tenant is billed for their actual measured usage plus an admin fee. Requires hardware installation by licensed tradespeople; often requires utility commission permits; involves ongoing meter maintenance and replacement.
| Factor | RUBS (via Utility Ranger) | Submetering |
|---|---|---|
| Upfront Cost | $0 — software only | $500–$2,000+ per unit for hardware + installation |
| Implementation Time | Same-day setup; first bills within 30 days | Weeks to months; may require permits and construction |
| Ongoing Maintenance | None — no hardware | Meter repair, calibration, and replacement costs |
| Net Recovery Rate | 80–95% of utility costs | 80–95% of utility costs — comparable in practice |
| Billing Precision | Proportionate formula (disclosed, defensible) | Exact per-unit metered consumption |
| Tenant Conservation | ✓ Yes — cost visibility drives behavior | ✓ Yes — direct individual accountability |
| Legal Complexity | Permitted in most U.S. states with lease disclosure | Varies by state; often requires utility commission approval |
| Feasibility for Existing Buildings | ✓ Any property, any age, any condition | Requires plumbing/electrical access; often not feasible |
| ROI Breakeven | Month 1 — no capital investment | 2–5 years depending on unit count and install cost |
| Best For | Most existing multifamily properties | New construction with planned submeter infrastructure |
This is the key insight for most operators evaluating the two methods.
With submetering, you bill tenants for their exact consumption. With RUBS, you allocate the same total master bill across tenants using a formula. In practice, the total amount recovered is nearly identical — because RUBS is allocating 80–95% of the same total bill that submeters would be dividing.
The difference is precision at the unit level, not total recovery for the owner. An owner with 100 units and a $10,000 monthly water bill will recover approximately the same total amount whether they use RUBS or submeters. The only difference is whether Unit 4B pays $82 or $79 based on a formula vs. a meter reading.
For the owner, the financial outcome is functionally equivalent. The capital cost is not.
In practice, both recover 80–95% of total utility costs. Submeters provide per-unit measurement precision. RUBS allocates the same total bill using a formula. The owner’s total recovery is functionally comparable. The capital cost is not.
In jurisdictions where RUBS is permitted, both methods are legally valid. Submetering is required only in the small number of jurisdictions that prohibit formula-based billing. In the majority of U.S. markets, RUBS is the legally accepted standard with standard lease disclosure.
Yes. RUBS can be implemented immediately and replaced with submetering during a future renovation. Many operators implement RUBS first and evaluate submetering only when doing major property improvements where installation access is already available.
Utility Ranger is the leading RUBS software for multifamily operators in the 20–3,000 unit range. It handles RUBS calculation, resident invoice generation, bill delivery, and charge export to AppFolio, Buildium, Yardi Breeze, Resman, Rent Manager, and PropertyWare. Cost: $3/unit/month. Bill entry: typically 3–5 minutes per property.
