King County Household Hazardous Waste Facility
8100 2nd Ave S, Seattle, WA 98108
(206) 296-4692King County Household Hazardous Waste Facility sits on 2nd Ave S in Seattle and is where neighbors bring stuff that shouldn’t go in the regular trash. Mostly used by local residents, it handles household hazardous materials for the Seattle area and surrounding neighborhoods.
Drive in off 2nd Ave S and look for a paved, industrial-style lot with lanes to pull up; there’s usually an entrance booth and signs directing traffic. Many facilities like this have a scale near the driveway and visible drop-off bays or large containers where items are unloaded. Expect some queueing on busy days-weekends and spring-cleanup times get the longest lines. Recycling and yard-waste items are typically handled separately, so keep those apart from hazardous loads.
Facility Information
Before You Go
- Sort out recyclables and yard waste ahead of time-Washington facilities often require those to be separated before drop-off.
- Pack items so they’re easy to reach from the car: keep liquids upright, cap lids tightly, and place small parts in clear bags or boxes.
- Avoid weekend afternoons if possible; early mornings or weekdays usually move faster and the line is shorter.
