Most household and remodeling debris can go in your container. California's disposal laws and the County landfill set the limits.
CalRecycle says it's illegal to dispose of hazardous waste in the garbage, down storm drains, or on the ground. The state's list includes lights and batteries, household and garden chemicals, paint and solvents, and car-related waste like motor oil. It also covers electronics, mercury items like old thermostats, and building materials such as asbestos and treated wood.
Orange County's landfills add their own rule. The County stopped taking treated wood waste at its landfills in 2021, so fence posts, decking, and other treated lumber need a separate route.
Liquids, fuel, and compressed gas cylinders don't belong in a dumpster either. Long, bulky items are accepted but may cost more to dispose of, so mention them when you book.
If you're unsure about an item, ask your account manager before it goes in.
