Most construction and cleanout debris is fine. California's trash bans and the receiving facility set what's off limits.
Electronics are the big one. The City's disposal guide says e-waste can't go in trash or recycling containers because it contains hazardous materials. That includes anything with a cord or batteries. CalRecycle adds every type of battery, fluorescent tubes, LED bulbs, and mercury items to the state's banned-from-trash list.
Paint and household chemicals are out too, along with motor oil, antifreeze, pesticides, and propane tanks. California also keeps tires and chemically treated wood out of the trash, and asbestos needs special handling.
On top of that, hazardous waste, liquids, solvents, and fuel can't go in a standard dumpster. Residents can take many of those items free to the Community Household Hazardous Waste Collection Center at UCSB, open Saturday, 9 a.m. to 3 p.m., and Sunday, 11 a.m. to 3 p.m.
If you're unsure about an item, ask your account manager before it goes in.
