Do you need a rental license to rent out property in Washington?

Washington does not license landlords at the state level. What the state sets is the floor: the Residential Landlord-Tenant Act, chapter 59.18 of the RCW, applies in every city and county. It covers deposits, notices, repairs and the landlord’s basic duties, including working smoke alarms and written information for tenants about fire safety and mold.

Fees and program details change. Confirm the current version with each city before you rely on any line above.

Tacoma treats renting out property as a business. A landlord needs a current City of Tacoma business license, and it has to be in the name of the owner of record. Without one, a Tacoma landlord cannot raise the rent or pursue an eviction.

The seller’s license does not transfer at closing, so apply in your own name, or your LLC’s, once the deed records. The license is the first item in a longer set of Tacoma rules that took effect in 2026, including a 180-day notice for rent increases and relocation assistance in some cases, and what Tacoma’s 2026 landlord rules mean for a buyer walks through the rest.

Kent runs a Rental Housing Registration and Inspection Program under chapter 10.02 of its city code. Rentals that are not owner-occupied are registered with the city on a one-year term, and a registration can carry over to a buyer for the rest of that term. Buildings other than single-family houses, condos and townhomes also need a rental housing business license, and those properties are inspected once every three years by a qualified rental housing inspector. A detached single-family house, a condo and a townhouse are exempt from the license and the inspection, though a detached house still registers. A property whose certificate of occupancy is less than four years old, with no code violations, is also exempt from inspection.

Get Kent’s current checklist before you schedule anything. In general these inspections look at basic health and safety items, many of them in the basement or utility closet:

• Smoke alarms and carbon monoxide alarms where they are required, and working.
• A water heater that is strapped, with a relief valve line that runs where it should.
• An electrical panel with its cover on and no open slots.
• A working heat source, and bedroom windows that open wide enough to get out.

If you are buying a Kent triplex or a small building on East Hill, ask the seller for the most recent inspection certificate and proof the registration is current. An item that failed and was never fixed becomes your repair the day you close.

The City of Spokane requires a landlord to hold a Washington business license with a City of Spokane endorsement and to register each long-term rental in the city’s rental registry every year. Code Enforcement treats tenant complaints as its top priority for inspections, and it also runs proactive inspections in an order it sets, including exterior checks of registered single-family rentals from the street. None of that replaces your own inspection before you buy.

Check which city the parcel is actually in. A Spokane mailing address does not always mean the City of Spokane: Spokane Valley is its own city with its own codes, and parts of the area are unincorporated Spokane County. If you are looking at older houses near Gonzaga, the license is one of several city rules to confirm, and buying a student rental near Gonzaga covers the others.

The Tri-Cities are three separate cities in two counties, and they do not share a rental program. Pasco is in Franklin County. Kennewick and Richland sit across the Columbia River in Benton County, and West Richland is its own city as well. Before you close, call each city’s code enforcement and business licensing offices and ask what a landlord needs there: a license, a registration, any inspection and how often.

This matters when you compare two similar duplexes on either side of the river. The purchase prices may look alike while the holding costs and the paperwork differ.

Auburn sits in both King and Pierce Counties, and it is a good example of a city where the only reliable answer comes from the city itself. The same goes for any Washington town not covered here. This is the order I would work in:

1. Pull the parcel record from the county assessor and confirm the property is inside city limits.
2. Search the city’s website and municipal code for “rental registration,” “rental housing” and “business license.”
3. Call the permit center or code enforcement. Ask whether the city requires a license or registration, whether it inspects and how often, and whether there are open code cases on the address.
4. Ask the seller in writing for any license, registration, inspection certificate or notice of violation, and read them before your inspection contingency ends.
5. If the property has a second unit, confirm it was permitted. A basement apartment the city does not know about cannot be registered as a rental, and the page on buying rentals in Washington covers what an unpermitted unit may need before it can be rented legally.

Licensing and inspection costs belong in the analysis as real line items. There is the license or registration fee, usually every year. There is the inspector’s fee every cycle in a city like Kent. And there are the repairs an inspection finds, which on an older house can be the biggest of the three.

There is also the cost of skipping it. In Tacoma, a missing business license stops a rent increase or an eviction. In other cities it can mean code enforcement penalties and a harder conversation with a tenant’s attorney. When I run a property, I enter the city’s current fees where I can confirm them and leave a reserve for inspection repairs on anything built before the 1970s.

City programs change, sometimes with little notice. Confirm current requirements with the city itself, and take anything your purchase depends on to a Washington landlord-tenant attorney.
