Lumber, drywall, stucco, roofing, flooring, carpet, ceiling tile, cabinets, fixtures, office furniture, and general cleanout debris are all fine in a roll-off container.
The hard limits are statewide. CalRecycle puts it bluntly: disposing of hazardous waste in the garbage, down storm drains, or onto the ground is illegal. The list reaches paint of both kinds, solvents, pesticides and herbicides, pool chemicals, acids and oxidizers, antifreeze, motor oil and filters, every type of battery including car batteries, fluorescent and metal halide lamps, and LED lights. Propane tanks and other compressed gas cylinders are out. Tires are banned as well, for mosquito and fire reasons rather than toxicity.
Two building materials catch Santa Clara projects in particular, and both are specific to California. Treated wood, the preserved lumber in decks, fences, and raised beds, has to be managed as hazardous waste in this state and cannot ride in a standard container. Asbestos turns up in the 1950s and 1960s housing stock across the city, in floor tile and its adhesive, in pipe lagging, and in textured ceiling coatings, and it needs a licensed abatement contractor.
Electronics deserve a mention given what this city builds. Monitors, computers, servers, printers, and televisions all need an e-waste route rather than a container, which matters on an office clearance where the furniture and the hardware come out of the same room.
Mention anything unusual to your account manager when you book and the separate route for it gets arranged alongside the container.
