Most remodel and cleanout debris can go in. The limits come from Washington State rules and from King County's list of what its facilities refuse.
Washington law says mercury-containing lights, such as fluorescent tubes and CFL bulbs, can't knowingly be put in the trash for a landfill. Pull them out before loading and take them to a collection site.
King County's disposal restrictions add more. TVs, computers, monitors, laptops, phones, and tablets are not accepted. Major appliances like fridges, washers, stoves, and water heaters are refused for disposal and must be recycled. Rechargeable, car, and button batteries are turned away, and asbestos needs County approval first.
Hazardous waste, liquids, paint, solvents, and fuel can't go in a standard dumpster either.
