Most debris from remodels, cleanouts, and yard projects is fine. California's statewide rules decide what has to stay out.
CalRecycle, the state's recycling agency, keeps a list of waste banned from the trash. It sorts the list into groups: lights and batteries, household and landscape chemicals, paints and solvents, car-related items, building materials, and electronics. That means no batteries, fluorescent tubes, pool chemicals, pesticides, latex or oil-based paint, antifreeze, or motor oil.
Two building materials catch people off guard. Asbestos can turn up in older roofing, flooring, and siding, and lumber treated with chemical preservatives has to be handled as hazardous waste. Tires are banned from the trash too, not because they're toxic, but to prevent mosquito breeding and tire fires.
Hazardous waste, liquids, paint, solvents, fuel, and asbestos can't go in a standard dumpster. If you have wet concrete to wash out, mention it when you book, since that needs its own arrangement.
Ask your account manager about anything you're not sure of before you load it.
