Most construction and cleanout debris is fine. The limits come from California rules and from what the county landfill will take.
The Fink Road landfill turns away hazardous waste, household chemicals, fluorescent bulbs, liquids, paint thinners, used oil, car batteries, and closed containers. TVs, computers, and other electronics have to be declared at the gate so they can be recycled. Appliances, mattresses, and tires also have their own pricing and must be declared.
Hazardous waste, liquids, paint, solvents, fuel, and asbestos can't go in a standard dumpster either.
Stanislaus County runs a household hazardous waste facility at 1710 Morgan Road in Modesto for chemicals and paint. Treated wood from fences and decks needs special handling, so let us know if your load includes it.
When you're unsure about an item, ask your account manager before it goes in.
