Submetering only saves money if you can actually bill from it — and billing tenants for utilities is governed by a patchwork of state and local rules. Get the meter right but the paperwork wrong, and you expose yourself to disputes or penalties. This guide covers the legal building blocks of tenant utility billing, with specifics for Pennsylvania.
Three Ways to Recover Utility Costs
Owners generally recover tenant utility costs one of three ways. Submetering installs a meter on each tenant's load and bills actual measured usage — including common-area loads in multifamily buildings. Ratio utility billing (RUBS) divides a master bill among tenants by a formula such as square footage or occupancy, with no individual meters. Flat fees fold a fixed utility charge into rent. Submetering is the fairest and most defensible because tenants pay for what they actually use — but it is also the most regulated.
Why Submetering Is Usually the Defensible Choice
Because submetering charges measured consumption, it both promotes conservation and withstands scrutiny far better than estimated methods. RUBS, by contrast, can be challenged as inaccurate or arbitrary, and some jurisdictions restrict it. When the dollars are significant, measured billing protects the owner.
Pennsylvania Rules
Pennsylvania permits landlords and property managers to install submetering systems and bill residents for individualized utility usage. State legislative activity has worked to define "submetering" — broadly, meters owned by a landlord ratepayer and installed to bill individual tenant usage or support energy efficiency. As with every jurisdiction, the details — disclosure requirements, what you may bill, and how — are set by statute and utility commission rules, so confirm current requirements before you bill. (In New York, for example, Local Law 88 sets a hard tenant-submetering deadline that operates on a different timeline.)
Accuracy Is a Legal Requirement, Not Just a Technical One
If you bill from a meter, that meter's accuracy can be challenged. This is why revenue-grade metering (ANSI C12.20, typically Class 0.5 or better) matters for billing applications: it is the accuracy standard that holds up when a tenant questions a charge. Operational-grade meters are fine for dashboards but risky for invoices.
Transparency and Disclosure
Whatever the jurisdiction, defensible billing shares common practices: disclose the billing method in the lease, show tenants the meter readings and calculation, bill consistently, and keep auditable records. Hidden markups and opaque math are where disputes and regulatory trouble begin.
What to Put in the Lease
A clean submetering arrangement is documented up front: state that utilities are submetered and billed on measured usage, identify what is included, describe how readings convert to charges, and explain dispute resolution. Clarity in the lease prevents most conflicts before they start.
Submetering gives you the fairest, most defensible basis for billing tenants — but only when paired with revenue-grade accuracy, lease disclosure, and compliance with your state's rules. In Pennsylvania, submetering is permitted; confirm the current statutory and utility-commission specifics before you bill.
