Tenant Rights for Sub-Metering vs. Master Meter Utilities in Oregon

Understanding your rights around utility billing is crucial as a renter in Oregon. Whether your apartment is individually sub-metered or you pay utilities based on a master meter, Oregon law protects how landlords can bill you and what information they must provide. This guide explains your rights, the difference between sub-metering and master metering, and exactly what to do if you think you’re being charged incorrectly—as defined by Oregon’s rental laws and government agencies.

What Are Sub-Metering and Master Metering?

When it comes to utilities like water, gas, and electricity, Oregon rental properties generally use one of two billing methods:

  • Sub-Metering: Each unit has its own meter, and renters pay based on the exact amount they use.
  • Master Metering: The whole property is measured with one meter, and the landlord divides the total bill among the tenants, usually by unit size, number of tenants, or similar method.

These systems affect how much you pay and how billing disputes are handled.

Your Rights as a Renter in Oregon

Oregon’s landlord-tenant laws require landlords to follow strict rules regarding utility billing, particularly if a service is sub-metered or master-metered. The key legislation is the Oregon Residential Landlord and Tenant Act (ORS Chapter 90). Here are your basic rights:

  • Written Disclosure: Your written rental agreement must state exactly how utility charges are calculated and whether your unit is sub-metered or master-metered.
  • Itemized Billing: If sub-metered, you must only pay for what you use—never extra for common areas or other tenants. If master-metered, landlords must use a fair and reasonable method to divide costs.
  • Access to Billing Information: You have the right to see the bill from the utility provider and the calculations used to determine your share.
  • No Extra Fees: Landlords cannot add surcharges or "handling fees" beyond what the utility company charges unless your lease explicitly allows it.

Official Forms: Utility Billing Disclosure

  • Form Name: Utility or Service Billing Notice
    • When to Use: If your landlord changes how utilities are billed, or begins charging for previously-included services, they must provide an updated notice per Oregon Housing and Community Services requirements.
    • Example: If your building moves from master metering to sub-metering mid-lease, your landlord issues this notice to update your records.

Common Utility Billing Problems and Solutions

Disputes can arise when billing isn’t clear or seems unfair. Here’s what Oregon renters can do:

  • Request Documentation: If you don’t understand your bill, ask your landlord for the calculation details and copies of the main utility bill.
  • Know Your Agreement: Make sure the way utilities are billed matches your signed lease or rental agreement.
  • Put It in Writing: If you have concerns, communicate in writing and keep a copy for your records.
  • Contact Oregon’s Tribunal: For unresolved disputes, you can contact the official residential tenancy dispute body, the Oregon Judicial Department (OJD), which oversees landlord-tenant cases through its civil court system.

How to File a Utility Billing Complaint in Oregon

If your complaint isn’t resolved with your landlord, here’s a step-by-step overview:

  • Step 1: Send a written complaint to your landlord asking for a billing explanation.
  • Step 2: If no resolution, consider using Oregon’s official Small Claims complaint process (Oregon Small Claims Court).
  • Step 3: Complete the "Small Claim and Notice of Small Claim" form (varies by county). This form starts the complaint process for financial issues like overcharged utilities.
  • Step 4: Attend a hearing scheduled by the court to present your documentation and evidence.

Your county court website will provide the most up-to-date forms and procedures for small claims cases.

If you believe you are being overcharged for utilities or not provided with the required disclosures, gather all documents and contact a local tenant resource before taking legal action.
