Emergency Biohazard Cleanup Near Downtown Addy Addy, WA

Addy is an unincorporated community and census-designated place in Stevens County, Washington, located on the Colville River along U.S. Route 395 between Colville to the north and Chewelah to the south.

Addy was first settled in 1851 by Magnus Flett, a retired Hudson's Bay Company employee, and fellow HBC retiree Thomas Stensgar obtained the area's first homestead in 1867.

The community began as a Swiss dairy settlement and was named in 1890 by E. S. Dudrey, the local storekeeper and first postmaster, for his wife Adeline, who was nicknamed "Addy."

Addy became a stop on the Spokane Falls and Northern Railway at the end of March 1892 and was platted the following year, in 1893.

In 1975 Alcoa built a magnesium smelter at Addy that became the largest employer in Stevens County, but the company closed the plant in 2001 because of unfavorable market conditions.

Addy was not tracked by the 2000 census and first appeared as a census-designated place in 2010, when it counted 268 residents; by the 2020 census its population had fallen about 22 percent to 210.

The town's first school was built in 1884, but the last Addy school closed in 1967 and students have been bused to Chewelah ever since.

Today Addy is a small highway town with a gas station, a coffee shop, and one restaurant, serving a primarily agricultural local economy.

Addy has a humid continental climate under the Köppen classification, with warm to hot summers and cold, sometimes severely cold, winters typical of northeastern Washington.
