We Only Have One Water Meter. Can We Bill Residents for Utilities?
Yes. If your building runs on one master water meter, you can bill residents their share using RUBS, as long as your lease discloses it and your state allows it. You take the real bill, subtract common areas, and allocate the rest across occupied units. No new meters, no construction, no waiting on a contractor.
This is the most common situation I see. Older buildings, duplexes, fourplexes, and plenty of newer small properties were built with one meter because it was cheaper for the builder. The owner inherits the problem.
Why not just put meters in?
You can. Most owners price it once and walk away. One property manager I know spent $10,000 submetering a four unit building. It will take the owner roughly five years just to break even, and that's before meter reading fees, replacement, and the occasional unit where plumbing makes the install harder than quoted.
RUBS has no hardware. You are billing from the master bill you already receive.
What if only some units pay for utilities?
Real buildings are messy, and this is where a lot of billing systems fall over. A recent client of ours runs a 13 unit property. Four residents pay utilities. Others are Section 8 and are handled differently. A rigid system wants to treat every unit the same.
What we did: combined the non-paying units into one line for simpler billing while keeping the occupancy details, so the math stays right and the paying residents are billed on a clean number. The utility allowance for subsidized units is accounted for instead of ignored.
Ask any vendor you are considering how they handle mixed buildings. If the answer is "we bill every unit the same," that is a sign the system was built for large corporate portfolios, not for you.
What happens when a resident moves in mid-month?
Charges should prorate by days occupied. A resident who moves in on the 18th should not carry a full month, and the vacant days should fall back to the owner. Prorating by hand is where small landlords lose hours every month and get disputes. Software should do it for you.
What do you need to start?
- Your last few master bills for each utility
- Unit list with square footage and occupant counts
- A lease addendum that discloses the utilities, the method, and any fee
- A decision on common area deduction (what you keep)
Setup on our platform takes about 15 minutes per property. For a new building, I recommend starting billing about 30 days after the first resident moves in.
What to look for in a partner when you only have one meter
Three things matter more than anything on a features page:
- Can you see and edit the calculation? With one meter, every number comes from your master bill. You should be able to trace each resident charge back to it.
- Are you the contact, or is the vendor? When a resident asks why the bill moved, you want to answer in one sentence. Outsourced call centers read from an account record, not your building.
- Is there a minimum? Many larger vendors have unit minimums that make small properties not worth their time. We charge $3 per unit per month with a $30 minimum, which covers up to 10 units.

FAQ
Can a landlord bill tenants for water without individual meters?
Yes, using RUBS, where permitted. The lease must disclose it, and some states and cities limit how and when.
Do I need to install submeters to bill residents?
No. Submetering is one option. RUBS is the alternative when meters aren't practical or the payback is too long.
How do I bill residents in a mixed building with subsidized units?
Account for the utility allowance on those units and bill the paying units on their real share. Your software should handle this without workarounds.
What if a unit is vacant?
Vacant units carry no resident share. The owner absorbs that portion and the remainder is allocated across occupied units.
How long does setup take?
About 15 minutes per property on our platform, once you have your bills and unit data.
