If You’re Billed by Unit Count, Not by Meter — There’s a Real Question You Can’t Answer Without Checking
Many multifamily and high-rise properties are billed a flat, fixed rate by the municipality — based on unit count or occupancy, not actual metered use. If that’s you, your master water meter may genuinely not affect this year’s bill. But it’s still the only tool that can tell you whether you’re overpaying, and whether that number is quietly working against your property’s value.
Direct answer: Some municipalities bill multifamily properties on actual metered volume, and some bill flat-rate by unit count or Equivalent Dwelling Unit (EDU), disregarding the master meter reading entirely. Which one applies to you changes everything about whether meter accuracy matters — and the only way to know for certain is to check your own rate schedule or ask your utility directly. This page walks through both scenarios honestly, including the one most owners never think to check: what an accurate meter reading could tell you about switching billing methods.
Two Very Different Situations — And They Call for Different Answers
Before anything else, it’s worth knowing which one actually describes your property.
Your Utility Bills You on Actual Metered Volume
How you bill your tenants — occupancy, RUBS, flat per-unit — is a separate, internal decision. If the utility charges your ownership entity based on the master meter’s actual reading, meter accuracy directly determines your bill.
Your Utility Bills You Flat-Rate, by Unit Count or EDU
Programs like NYC’s Multi-Family Conservation Program, or many EDU-based tariffs, bill a fixed annual charge per unit — regardless of what the master meter shows. The meter typically stays in place for leak detection and engineering records only.
If You’re on Path 2, There’s a Detail
Almost Nobody Checks
Flat-rate and EDU billing programs typically don’t work the way most owners assume. The relationship
between actual usage and your bill is not balanced both ways.
If your actual usage is lower than the flat rate assumed: you’re overpaying, every single year — and unless you specifically pull your own master meter data and compare it, there’s no mechanism that tells you. The utility isn’t going to volunteer a refund. The only way to find out is to look.
Why an Accurate Meter Reading Still Matters, Even on Flat-Rate Billing
You can’t know whether switching to metered billing would save you money without accurate data — and if your master meter is over-registering, the picture you’re looking at is wrong in exactly the direction that hides the opportunity. An over-reading meter makes your real usage look higher than it actually is, which can make metered billing look like a worse deal than it would actually be.
Correcting the meter first means that if you do decide to evaluate a switch — or request a comparison under a program that allows it — you’re working from a number you can actually trust, instead of one that’s been quietly overstating your usage the whole time.
This Is Where NOI Comes In — And Why
Housing Assets Feel It Directly
For multifamily and high-rise properties, water and sewer cost is one of the largest controllable operating expenses on the books. Under the income approach used by most lenders and many municipal assessors, Property Value = Net Operating Income (NOI) ÷ Cap Rate. Every dollar you’re overpaying — whether from an inflated meter or from staying on a flat-rate program that no longer fits your actual usage — is a dollar suppressing your NOI, and by extension, your property’s appraised value.
One Important Distinction: It's Your Value That Moves, Not the Cap Rate
Your cap rate is set by the market — comparable sales, investor return expectations, asset class, and location. Nothing about correcting your own meter or switching billing methods changes that number. What moves is NOI, and because value is NOI divided by cap rate, a lower expense at the same market cap rate produces a real, calculable increase in appraised value.
In practice, that means: if switching to metered billing turns out to be favorable, and the meter feeding that new bill is corrected with the FCD so it reflects actual usage rather than an inflated reading, the resulting drop in water and sewer expense flows straight to NOI — and at the same cap rate your property already trades at, that can translate into a meaningful increase in what the property is worth.
The only way to know whether that applies to your property is to get an accurate metered reading and have it properly analyzed against your current billing method. Without that, you genuinely cannot know whether you’re leaving money — and value — on the table.
What a Free Review Actually Involves — and What It Doesn’t
We start by figuring out which path you’re actually on — not by assuming.
You’re Billed on Metered Volume
If your master meter shows signs of over-registration, correcting it reduces your water and sewer bill directly, starting the next billing cycle.
You’re Billed Flat-Rate or by EDU
We help you get an accurate reading first, then flag whether your actual usage suggests a metered comparison is worth pursuing with your utility — with the real trade-offs explained, not oversold.
There’s Nothing to Find
If neither applies to your property, we’ll tell you that directly. The review is free either way, and there’s no obligation.
