Portland Rental Registration: Schedule R Guide
Updated October 2026 · 5 minutes
All residential rental units in Portland, including houses, duplexes, and rooms in a house, must be registered annually via Schedule R, whether or not a fee is owed.
Understanding Portland Residential Rental Registration
The City of Portland requires all residential rental property owners to maintain compliance through the Residential Rental Registration program. For property managers and landlords, this means that Portland residential rental registration is not a one-time task but an annual obligation that must be synchronized with your business tax filings.
The Role of Schedule R
The core of this compliance requirement is the Schedule R form. It must be completed and attached to your City of Portland and Multnomah County Business Tax Return, and it lists the addresses of all residential rental units you own within the city. Owners of 10 or more units, or those who want to file electronically, should use the city's Residential Rental Registration Import Sheet. The form defines a residential rental unit as a dwelling unit, as defined by ORS 90.100, that is rented or offered for rent for more than thirty consecutive days. That includes, but is not limited to, rental houses, cottages, mobile homes, duplexes, apartments, condominiums, and rooms in a house.
Fee Structure and Exemptions
The city lists the registration fee as $70 per unit for tax years 2023, 2024, and 2025. Residential rental units regulated at or below 60% of the Area Median Income (AMI) are exempt from the annual registration fee when you file Schedule R. Those units must still be included on Schedule R, and you must indicate which units are affordable. To confirm or request an exemption, contact the city's Rental Services Office. Units not regulated by the City need a copy of their regulatory agreement.
Deadlines and Penalties for Non-Compliance
The city says that failing to submit the Business Tax Return and related documents, including Schedule R, may result in penalties. Late fee payments bring late payment penalties and interest. Maintaining a proactive tracking system for these annual filings helps you avoid these costs.
Managing Compliance Across Your Portfolio
For portfolio-level operators, tracking these requirements manually across multiple properties can be complex. Ensuring that your Schedule R filings are accurate and submitted alongside your business taxes is a critical component of your operational compliance. By centralizing your registration data, you can keep your portfolio in good standing with the City of Portland.
