City government in Washington (state)
City classes 
Legally, a city in Washington can be described primarily by its class. There are five classes of cities in Washington:
- First class cities (3.6% of cities in the state)
- Second class cities (3.2%)
- Towns (24.6%)
- Unclassified cities (one city)
- Code cities (68.3%)
First class cities are cities with a population over 10,000 at the time of reorganization and operating under a home rule charter. They are permitted to perform any function specifically granted them by Title 35 RCW (Revised Code of Washington). Among them are Seattle, Tacoma, Spokane, Vancouver, and Yakima.
Second class cities are cities with a population over 1,500 at the time of reorganization and operating without a home rule charter. Like first class cities, they are permitted to perform any function specifically granted them by Title 35 RCW. Among them are Port Orchard, Wapato, Omak, and Colville.
Towns are municipalities with a population of under 1,500 at the time of reorganization. Towns are not authorized to operate under a charter. Like the previously listed cities, they are permitted to perform any function specifically granted them by Title 35 RCW. Among them are Steilacoom, Friday Harbor, Eatonville, and Waterville. In 1994, the legislature made 1,500 the minimum population required to incorporate.
Unclassified cities are cities which are not operating under any other class. Only one city—Waitsburg, in Walla Walla County—is unclassified. It operates under the 1881 territorial charter under which it was organized, eight years before Washington was admitted to the Union in 1889.
Code cities were created by the state legislature in order to grant the greatest degree of local control to municipalities possible under the state constitution and general law. This classification has been adopted by the majority of municipalities in Washington, including Renton, Bellevue, Olympia, Longview, Pullman, and University Place.
Code cities (shorthand for optional municipal code cities, as encoded by Title 35A RCW) are authorized to perform any function not specifically denied them in the state constitution or by state law. They may perform any function granted to any other city classification under Title 35 RCW.
Governmental forms 
A city in Washington can be described secondarily by its form of government. Cities and towns are specifically authorized three forms of government:
The city of Shelton is the only one still using the three-member commission form of government.
In addition, code cities (see above), if their population is over 10,000, may incorporate as charter code cities. They may then "set out any plan of government deemed 'suitable for the good government of the city'" (RCW 35A.08.050), which need not be a commission, mayor-council, or council-manager form. No charter code city has opted for a different type of government as of 2012[update].
