Whatcom County, WA Right to Farm: Farm Nuisance Protection (2026)

Adopted to protect Whatcom County's agricultural economy, WCC § 14.02.030 states that no land-based farm operation conducted for commercial purposes and run consistent with current good management practices 'shall be or become a nuisance or a disorderly house...or a breach of peace,' regardless of later changes in the surrounding area's zoning or land use. The protection covers commercial production of land-based farm products such as dairy, livestock, berries and produce, and expressly includes noise, dust, odors, flies, chemical drift, aerial spraying and equipment operated at any hour (WCC § 14.02.020).

The county pairs that liability shield with mandatory notice to newcomers: under WCC § 14.02.040, anyone selling real property within one-half mile of land mapped as agriculture or rural, or within one-half mile of an active farm operation, must have the buyer sign a recorded disclosure warning that noise, manure spreading and pesticide application 'may occur...for certain periods of limited duration' and that the county 'will not consider to be a nuisance' those impacts. Discretionary development permits issued within the same half-mile radius, per WCC § 14.02.050, must include a covenant binding the developer and future owners to refrain from suing the county or the neighboring farm over lawful agricultural activity; the hearing examiner may lift that covenant only on a finding that removing it will not increase liability risk. The chapter does not override state or federal law and does not exempt a farm from odor, pesticide or water-quality rules that otherwise apply.
