Investigators have identified a suspect in the fires, said Leslie Hynes, spokeswoman for Snohomish County Fire District 1.
No injuries were reported, she said.
The fires broke out between about 4:45 p.m. and 5:15 p.m. in the Cypress Way area, south of Lynnwood.
It's not clear in what order they were set, Hynes said.
One fire was in a garbage bin at a minimart at the intersection of Cypress Way and Larch Way.
One was in a garbage can next to a house in the 20400 block of Cypress Way.
That fire burned a small area of siding and caused about $7,500 damage, Hynes said.
Another fire was reported in a garbage can that was set out by the street in the 1800 block of W. Cypress Way.
The Snohomish County Fire Marshal and Sheriff's offices are investigating.
