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

32B's Agricultural Lands regulations, states that agricultural activities conducted on designated farmland in compliance with acceptable agriculture practices are presumed reasonable and cannot be found a nuisance unless the activity has a substantial adverse effect on public health or safety. 200 expressly preserves that. 220 to be attached to development and building permits issued on or near designated farmland. Before a sale, exchange, gift, or lease-with-option-to-purchase closes on farmland or adjacent property within 1,300 feet, the seller must give the buyer the disclosure text and record an acknowledgment of receipt with the county auditor.

The disclosure text itself warns incoming residents that they may face noise, odors, fumes, dust, smoke, aircraft and machinery operation, manure storage and disposal, and chemical or organic fertilizer, herbicide, and pesticide applications from nearby farms. This structure means the protection runs with specific designated farmland parcels and their immediate 1,300-foot buffer, not with agricultural activity generally across the unincorporated county, and it applies only where the underlying practices meet the state-recognized acceptable agriculture practices standard.
