Troutdale, OR Rental Property Rules: Rental Registration (2026)

Portland City Code 7.02.890 requires every residential rental owner within city limits to register each unit annually through the Rental Services Office (administered by the Revenue Division). The 2024/2025 Residential Rental Registration fee is $60 per unit, paid with the Business License. Nonpayment adds to a landlord's Business License Tax bill and disqualifies the owner from deducting rental expenses on their City/County business tax. Registration data feeds the Portland Housing Bureau's landlord outreach and the FAIR ordinance compliance system. Gresham Revised Code Chapter 7.80 (Residential Rental Housing Program) requires landlords to obtain a rental license, pay an annual fee (~$55/unit in 2024), and pass periodic inspections by the Rental Housing Inspector for compliance with the Oregon Residential Landlord-Tenant Act and ORSC habitability. Troutdale and Fairview have lighter registration requirements. Unincorporated Multnomah County does not license rental units but enforces statewide habitability under ORS 90.320 and the Oregon Residential Specialty Code through county building officials. All Oregon rental units built before 1978 require lead-based paint disclosure per federal Title X and EPA RRP rule. Smoke alarms and CO detectors mandated under ORS 479.270 and OAR 837-047.
