Portland rental compliance guides

Portland requires residential rental property owners to register through the Residential Rental Registration program, an annual obligation centered on Schedule R. The form is completed and attached to the City of Portland and Multnomah County Business Tax Return and lists the addresses of all residential rental units owned within city limits, with a residential rental unit defined as any dwelling unit, including houses, cottages, mobile homes, apartments, or individual units. For the 2025 tax year, the registration fee is $70 per unit. Units regulated as affordable housing at or below 60% of Area Median Income may be exempt from the fee, though they still must be registered and their status indicated on the Schedule R form. If the city identifies unregistered units through data matching, it issues a notice, and an owner who fails to respond may face civil penalties in addition to the standard registration fees. The city's Rental Housing Maintenance program sets inspection standards requiring rental units to meet basic habitability and safety requirements, including functioning structural, electrical, plumbing, and heating systems and working smoke and carbon monoxide detectors. Regular internal audits help identify potential issues before they are flagged by the city, and keeping a detailed record of maintenance activities and repairs demonstrates a proactive approach. Compliance is a continuous process rather than a one-time hurdle. Below are Tusk's plain-language guides to the requirements currently covered in our library.
