What is RUBS?
RUBS stands for Ratio Utility Billing System. It splits a shared utility bill among residents using a pre-set formula.
When does RUBS apply?
- Multifamily One city water meter for the whole property. SNSHN divides the bill among occupied units.
- Single-family Single-family residents pay their own full water bill directly.
How does SNSHN calculate RUBS?
We use bedroom count across occupied units, not headcount.
Your charge = (Bedrooms in your unit ÷ Total bedrooms in all occupied units) × Total building water bill
Worked Example
Duplex. Total water bill $200.
| Unit / Resident | Bedrooms | Share | Amount |
|---|---|---|---|
| Unit A (Kevin) | 3 | 3/5 | $120.00 |
| Unit B (Karen) | 2 | 2/5 | $80.00 |
| Total | 5 | — | $200.00 |
Budget tip: Water is billed quarterly. A cycle covering March → June may post in late July and is due with August rent.
