Full Breakdown
Portland City Code § 33.110.100.B.8-10 grades agricultural use by zone: allowed outright in the RF and R20 single-dwelling zones, a conditional use requiring case-by-case approval in R10 and R7, and prohibited in R5 and R2.5 unless the use qualifies under Chapter 33.237's Food Production and Distribution rules for a Market Garden. Section 33.110.020 confirms the RF zone itself "is intended to generally be an agricultural zone," though it's labeled Residential Farm/Forest for reference. There is no separate right-to-farm nuisance-protection ordinance in the city code.
Violations & Fines
Farming in a zone where Agriculture is prohibited or without required conditional-use approval is a zoning code violation, enforced by the Bureau of Development Services through its code compliance process.
