Why North Carolina owners are submetering now

One meter pays for every unit

On a master meter, the owner pays for every running toilet and long shower in the building. A meter on each unit puts each resident's use on that resident's bill.

Billing has to come from a meter

North Carolina lets owners bill residents for water only from each unit's own meter, at the utility's usage rate plus a small monthly fee. Formulas that split the master bill are not allowed.

Rates keep climbing

Durham raised water and sewer rates about 12% and Greensboro about 11% for fiscal 2027. In Chapel Hill and Carrboro, usage charges run about $81 a month for a typical apartment. See the table below.

Leaks show up fast

We read every unit each month, so a stuck flapper or a hidden leak shows up at the next read. That matters here: residents can't be billed for a leak they didn't know about or had reported.

North Carolina water billing rules at a glance

TopicWhat the rule saysHow AQUEES applies it
Who may billG.S. 62-110(g) lets owners of rental housing, condominium associations and townhome associations in planned communities charge residents for water and sewer. The Utilities Commission's Rule R18 covers owners of 15 or more rental homes in an apartment complex or manufactured home park.We confirm with you which rules apply to your property before billing starts.
Certificate of authorityUnder Rule R18-3, an owner of 15 or more rental homes needs a certificate from the Utilities Commission for each property before charging for water. No bond is required. If the Commission doesn't act within 30 days of a complete application, it is deemed approved. When the property is sold, the seller and buyer file Form WR2 to transfer it.We supply the rates, sample bill and meter plan for your application. The certificate is in the owner's name.
Metered use onlyApart from the administrative fee, every charge must be based on the unit's metered use (G.S. 62-110(g); Rule R18-6). Formulas that split the master bill are not allowed, apart from a narrow, Commission-approved exception for some buildings built before 1989 (Rule R18-8).Every unit gets its own meter, read every month.
Price limitThe usage rate charged to residents must equal the supplier's usage rate, with no markup (Rule R18-6(a)). Rate changes can be passed through on 14 days' notice (Rule R18-6(b)).Unit bills use your utility's published rate, and we update them when the utility changes its rates.
Administrative feeA Commission-approved fee of up to $3.75 a month may be added for meter reading, billing and collection (Rule R18-6(a)).The fee is set in your application and shown as its own line on each bill.
Bills and collectionBills go out at least monthly, with a due date at least 25 days after the billing date and a toll-free number for questions. No late, connection or disconnection fees, and no water shutoff for nonpayment. Excess use from a leak the resident didn't know about, or had reported, can't be billed (Rule R18-7).Our bill format is built to Rule R18-7, and leak alerts at every monthly read help you fix leaks quickly.
Resident disclosures and recordsAt lease signing, residents get the rates, the rules, a copy of Chapter 18 and the Public Staff's contact details (Rule R18-7(g)). Billing records stay available at an on-site or North Carolina office (Rule R18-5).We prepare the disclosure packet for your leases and the monthly billing records for your office.
InstallationMeter installation is plumbing work, normally done under a local plumbing permit. Residents are told how meters are read, and meter testing follows the Commission's Rules R7-28 to R7-33 (Rule R18-7(h)).Your preferred plumber pulls the permit and installs the meters we specify.

North Carolina water submetering FAQ

Is water submetering legal for apartment buildings in North Carolina?

Yes. G.S. 62-110(g) and the Utilities Commission's Rule R18 let owners bill residents for water and sewer from each unit's own meter, at the supplier's usage rate plus an administrative fee of up to $3.75 a month. Owners of 15 or more rental homes need a certificate from the Commission for each property before billing.

Do I need a certificate from the North Carolina Utilities Commission?

If you own 15 or more rental homes in an apartment complex or manufactured home park, yes. Rule R18-3 requires a certificate of authority for each property before you charge for water. No bond is required, and a complete application is deemed approved if the Commission doesn't act within 30 days. When you sell, you and the buyer file Form WR2 to transfer it.

Can I add a markup or late fee?

No. Residents pay the supplier's usage rate for their metered use, plus the approved administrative fee of up to $3.75 a month. Late, connection and disconnection fees are not allowed, and water can't be shut off for nonpayment.

Can condominium and townhome associations bill on metered use?

Yes. G.S. 62-110(g) also covers condominium unit owners' associations and owners' associations for townhomes in planned communities. Charges must be based on each unit's metered use, at no more than the supplier's usage rate. We review your declaration with you before billing starts.
