Most household and remodeling debris is fine to load. California's rules on hazardous waste set most of the limits.
The state recycling agency, CalRecycle, says it's illegal to put hazardous waste in the garbage. That covers every kind of battery, fluorescent tubes, paint and paint thinner, pesticides, antifreeze, motor oil and filters, and propane tanks.
Some construction materials are on the list too. Asbestos, found in some older roofing, flooring, and siding, can't go in a dumpster. Wood treated with chemical preservatives has to be handled as hazardous waste.
California also bans tires from the trash, even though they aren't hazardous. Electronics like TVs, computers, and phones need to be recycled instead of thrown away.
For household items, Vacaville residents get a free annual landfill pass for up to 1,000 pounds, which you can request through your City garbage service.
If you're not sure about an item, ask your account manager before it goes in.
