Item: House paint (latex and oil-based), paint cans, stains, varnishes, thinners Jurisdiction: Seattle city limits, Washington (King County) Last updated: July 2026
Quick Answer
Seattle residents have three routes for paint disposal. (1) King County HHW facilities — North Seattle (12550 Stone Ave N) or South Seattle (8100 2nd Ave S) — accept oil-based paint free of charge, no appointment needed. (2) PaintCare drop-off sites accept latex and oil-based paint, stains, and varnishes free for all Washington residents, businesses, and government agencies. (3) Home Collection Program (206-296-4692) provides in-home HHW pickup for King County residents 65+ or with disabilities who cannot drive — operates Wednesdays 9am-3pm, but does not accept latex paint. For latex paint only: if it is fully dried or hardened, it can go in the regular trash with the lid off so the hauler can verify it is solid.
Do not put liquid latex paint in the garbage. It can damage septic and sewage systems. Always harden latex paint completely before throwing it away.

Does Seattle Offer Curbside Paint Pickup?
No standard curbside pickup exists for household hazardous waste paint in Seattle. Paint is classified as hazardous waste and requires special handling.
Home Collection Program (Exceptions)
King County offers a Home Collection Program for residents who cannot transport HHW themselves.
- Eligibility: King County residents 65 years or older, or with a disability that prevents driving.
- Phone: 206-296-4692 to schedule.
- Operating hours: Wednesdays 9am-3pm.
- Cost: Free for eligible residents.
- Important limitation: The program does NOT collect latex paint, tires, electronics, or medications. It collects oil-based paint and other HHW.
- Preparation: Wastes must be sealed and placed upright in boxes for pickup.
If you are eligible but have latex paint to dispose of, you will need to use PaintCare drop-off, HHW drop-off, or harden the latex and put it in the trash.
King County HHW vs. PaintCare
Seattle has two complementary drop-off systems that together cover all paint types.
1. King County HHW Facilities
These county-run facilities accept household hazardous waste — including oil-based paint, paint thinners, solvents, and strippers — free of charge for King County residents.
| Facility | Address | Hours | Notes |
|---|---|---|---|
| North Seattle HHW | 12550 Stone Ave N | Sun-Tue 9am-5pm | Free, no appointment |
| South Seattle HHW | 8100 2nd Ave S | Thu-Sat 9am-5pm | Free, no appointment |
| Factoria HHW | 13800 SE 32nd St, Bellevue | Tue-Fri 8am-4pm, Sat-Sun 9am-5pm | Free, no appointment |
| Auburn Wastemobile | 1101 Outlet Collection Way | Sat-Sun 10am-5pm year-round | Free, no appointment |
All facilities are closed major holidays. No appointment is needed at any location.
What is accepted: Oil-based paint, paint thinner, paint stripper, solvents, stains, varnishes, and other HHW.
2. PaintCare Drop-Off
PaintCare is a statewide program funded by paint manufacturers. It is separate from the county HHW system.
- Who can use it: Free for all Washington residents, businesses, and government agencies.
- What is accepted: House paint and primers (latex and oil-based), deck and concrete sealers, clear finishes, stains, and varnishes.
- What is NOT accepted: Paint thinners, paint strippers, solvents — these must go to King County HHW facilities.
- Where to find a location: Visit paintcare.org and enter your ZIP code.
- Quantity limits per visit: Not confirmed in available sources. Check with the specific PaintCare location.
Which one should you use?
| If you have... | Go to... |
|---|---|
| Latex paint (liquid) | PaintCare or harden and trash |
| Oil-based paint | PaintCare OR HHW facility |
| Paint thinner, stripper, solvent | HHW facility only |
| Stains and varnishes | PaintCare |
| Small quantity of dried latex | Regular trash (lid off) |
Latex vs. Oil-Based Paint — Different Rules
This is the most important distinction in paint disposal. Latex and oil-based paints are handled completely differently.
Latex Paint
Latex paint is water-based and not classified as hazardous waste once it is fully dried or hardened.
How to harden latex paint for trash disposal:
| Method | How to do it |
|---|---|
| Air dry | Pour thin layers (under 1 inch) into a cardboard box or container and let air dry completely. |
| Cat litter | Mix an equal amount of cat litter into the paint can. Stir and let it sit until solid. |
| Paint hardener | Use a commercial paint hardener product following package instructions. |
After hardening:
- Leave the lid off the paint can so the garbage hauler can verify it is solid.
- Place in your regular trash cart.
- Do NOT pour liquid latex down drains or into the ground. It can damage septic systems and sewage infrastructure.
Oil-Based Paint
Oil-based paint (also called alkyd paint) is classified as hazardous waste. It cannot go in the garbage, even if dried.
Options for oil-based paint:
- Take to any King County HHW facility (free, no appointment).
- Take to a PaintCare drop-off location (free for all WA residents).
- Schedule Home Collection Program pickup if eligible (does not accept latex but does accept oil-based).

What to bring

- Paint in original labeled containers with secure lids.
- If containers are unlabeled, ask staff about acceptance.
- Limit loose containers to a reasonable household quantity.
Business and Bulk Quantity Rules
Unlike many city programs, PaintCare does accept paint from businesses and government agencies free of charge. This makes it a good option for contractors and property managers.
King County HHW facilities may have quantity limits for commercial users. Businesses with large volumes should:
- Call 206-296-4692 to verify quantity limits and requirements.
- Consider PaintCare's bulk pickup options for very large quantities.
- Contractors with regular paint waste should set up a commercial account with a licensed hazardous waste transporter.
Apartment and Renter Edge Cases
Paint disposal in Seattle is building-agnostic — apartment and condo residents can use the same drop-off options as homeowners.
- King County HHW facilities and PaintCare drop-off sites are open to all King County residents regardless of housing type.
- The Home Collection Program is available to eligible seniors/disabled residents regardless of whether they live in a house or apartment.
- Property managers with bulk paint from multi-family units should contact King County HHW or PaintCare for guidance on large quantities.
How to Prepare Paint for Disposal
For PaintCare or HHW Drop-Off
- Keep paint in original containers with legible labels.
- Secure the lid so it will not leak during transport.
- Place containers upright in a sturdy box or tub to prevent tipping.
- Transport in the trunk or cargo area — not in the passenger cabin.
For Home Collection Program
- Wastes must be sealed and placed upright in boxes.
- Call 206-296-4692 for preparation instructions specific to your items.
For Garbage Disposal (Dried Latex Only)
- Harden completely using air drying, cat litter, or commercial hardener.
- Leave the lid off so the hauler can see the paint is solid.
- Place in regular trash cart.
Donation
If you have unused, unopened paint in good condition, consider donating it to:
- Schools and theater groups
- Nonprofit organizations
- Community art programs
- Habitat for Humanity ReStore
Call the organization first to confirm they accept paint donations.
