Household Hazardous Waste


Effective June 22, 2021, fully vaccinated members of the public visiting County operated facilities are not required to wear face coverings or physically distance themselves from others. Unvaccinated members of the public visiting County operated facilities are required to wear face coverings and physically distance themselves from others.

Facility Hours:

Beginning January 2, 2021 hours of operation will be Wednesday - Saturday from 8:00am - 4:00 pm. This change will provide staff additional time to process the high volumes of incoming materials at the facility. Hours for businesses disposing of hazardous waste are by appointment only. 

Household hazardous wastes (HHW) are household products that contain potentially hazardous ingredients that require special care when disposing of them. HHW’s are products
that contain corrosive, toxic, ignitable, or reactive ingredients, such as oil-based paints, cleaners, oils, batteries, and pesticides. Improper disposal of HHW can pollute the environment and pose a threat to human health.

The Snohomish County HHW facility is free to residential customers, with the exception of latex based paint (see below). For loads larger than 40 gallons call prior to arrival. Conditionally exempt small quantity generator businesses may use the facility for a fee, and by appointment only. Call for fees and more information.
