Rental registration in Benton County depends on your city. Prosser requires a rental business license — $10 to register, $5 to renew yearly — with a safety inspection every five years. Kennewick, Richland, West Richland, and the unincorporated county run no registration program.
Washington lets cities run rental inspection programs under RCW 59.18.125, and in Benton County only Prosser, the county seat, has adopted one. Prosser landlords buy a rental business license — $10 initial, $5 annual renewal — and each unit must pass a health-and-safety inspection every five years, done by the city for a fee or by a qualified private inspector the owner hires. Kennewick, Richland, West Richland, and unincorporated Benton County require no rental registry, license, or routine inspection. Landlords everywhere still owe the smoke and carbon-monoxide detector, deposit, and habitability duties in RCW 59.18.
In Prosser, renting without the required license or skipping the five-year inspection can bring code-enforcement penalties and orders to correct. Outside Prosser, there is no county registration requirement to violate.
