Short-term rental permit rules in Benton County, WA — also called Airbnb permits, vacation rental licenses, or STR registration — list the application steps, fees, and operating requirements for hosting.
Unincorporated Benton County has no short-term-rental permit or licensing chapter. STRs operate under county zoning plus a Washington state business license. The Tri-Cities regulate rentals within their own limits.
Benton County's code, current through Ordinance 663 in 2025, contains no dedicated short-term-rental chapter, so a whole-home rental near Red Mountain wine country or one housing a Hanford contractor isn't specially permitted or capped by the county. It must simply fit the zoning district and carry a Washington State business license obtained through the Business Licensing Service. That's a lighter touch than tourist-heavy Washington counties. Inside the cities it varies: Kennewick is notably STR-friendly and requires only a general city business license with no special STR permit, while Richland, West Richland, and Prosser set their own rules. Always check HOA covenants first.
With no county STR ordinance, there's no county permit to violate, but operating without the required Washington business license exposes hosts to Department of Revenue penalties, and zoning violations draw county code enforcement.
