Summary
Washington County's AF-5 Agriculture and Forest District carries a built-in right-to-farm protection: CDC § 348-1 warns rural residents they 'will be subject to normal and accepted farming and forestry practices,' and § 348-4.2 requires most new rural uses to sign a recorded waiver giving up the right to complain about neighboring farm operations.
The purpose of this agricultural and forestry district is to promote agricultural and forest uses on small parcels in the rural area, while recognizing the need to retain the character and economic viability of agricultural and forest lands, as well as recognizing that existing parcelization and diverse ownerships and uses exist within the farm and forest area.

Full Breakdown
Rather than a standalone right-to-farm ordinance, Washington County builds farm protection directly into its agricultural zoning. ' That protection is enforced through the permit process rather than left as aspirational language. Nearly every Type I and Type II use approved in the AF-5 District, from a home occupation to a family day-care provider to a replacement dwelling, must come with a waiver 'of the right to remonstrate against commonly accepted farm or forest practices' recorded with the county's Department of Assessment & Taxation. 203(2)(c), or forestry uses on adjacent lands devoted to farm or forest use,' before the same waiver of remonstrance is recorded.
Together the two provisions mean a new neighbor in the AF-5, AF-10 or AF-20 Districts cannot later use nuisance complaints, code enforcement, or a land-use appeal to shut down ordinary farm noise, dust, spraying or equipment traffic next door. 2 for dwelling replacements. These protections apply only within the county's farm and forest zoning districts in the unincorporated area; land inside Hillsboro, Beaverton, or another city is not subject to this waiver requirement.
Violations & Fines
Approving a Type II or Type III use in the AF-5, AF-10 or EFU Districts without the recorded waiver of remonstrance violates the permit conditions under CDC § 215-1, and the county can deny or condition a later building permit over the missing waiver under § 215-2. Confirmed violations are prosecuted under Washington County Code Chapter 1.14 (§ 215-3), and a property owner who files a nuisance complaint against an adjacent farm despite having recorded the waiver risks having that complaint dismissed as inconsistent with the recorded document.
