Kennewick, WA Home Business: Customer Traffic Restrictions (2026)

Customer traffic is the most-cited home-occupation impact because neighbors notice it directly and because the KMC Title 18 framework distinguishes home-occupation tiers in large part by traffic intensity. Type 1 home occupations under KMC Title 18 typically permit a limited number of client visits per day, frequently expressed as 4 to 8 per day or 1 to 2 vehicles parked on-site at any time, with restrictions to daytime/evening hours (commonly 8 a.m. to 8 p.m. or 9 a.m. to 9 p.m. depending on the district). Off-street parking for clients is typically required if visits exceed a threshold; clients may not park on the residential street if doing so would displace residential parking or block driveways. Commercial deliveries are typically limited to UPS, USPS, FedEx, and similar light commercial vehicles; semi-trailer deliveries are usually prohibited as inconsistent with residential character. Type 2 home occupations (medical practitioners, attorneys, instructors with multiple students at once, contractor offices with employees and equipment) require a conditional-use permit from the Kennewick Hearing Examiner under KMC procedures and RCW 35A.63.170; approvals typically condition customer hours, maximum daily/weekly client count, required off-street parking, and screening. Persistent customer-traffic violations of permit conditions are grounds for revocation after notice and hearing. Land-use appeals follow the Land Use Petition Act (RCW 36.70C).
