What items are banned from roll-off dumpsters?
Hazardous materials top the list: paint cans, solvents, pesticides, motor oil, and anything with a flammability warning on the label. Batteries, whether car batteries or lithium packs, go elsewhere entirely, and so does anything with a compressed gas cylinder like a propane tank. Tires get rejected by most landfills outright. Electronics with circuit boards, old TVs, and refrigerants-holding appliances usually need a separate drop-off, not a bin. Medical waste, asbestos, and railroad ties are also off the table. If you're not sure whether something qualifies, check our dumpster rental cost page for guidance or call before you load it. Tempe Junction households doing a big cleanout often assume "trash is trash," but landfills that serve this area sort loads and bill back contamination fees. That single bad tire or leaking can costs more than the 10 yard dumpster rental itself. For anything under a construction context, pair your bin order with our construction dumpster rental guidance so your crew knows the rules before day one.
Can I put construction debris in a dumpster?
Yes, most construction debris is fine: drywall, lumber, shingles, concrete in smaller amounts, and general demo waste. The catch is weight, not category. A 30 yard dumpster rental filled with wet concrete or dirt can blow past its weight allowance fast, and overloaded bins get flagged before pickup. Review dumpster weight limits before you fill, especially on roofing tear-offs where shingles are dense. Renovation jobs across Tempe Junction generate a mix of debris, and separating clean wood from painted or treated wood matters if your hauler has different disposal streams. If you're gutting a kitchen or bath, our home renovation porta potty customers usually order the 20 yard dumpster rental for mid-size jobs, and it handles standard debris without issue. Full dumpster size comparisons are on dumpster sizes and dimensions if you're unsure what fits your pile.
Do I need a permit for dumpster placement?
Placement in the public right of way, like a street or sidewalk in Tempe Junction, needs confirming with the city before you order. We have not verified a specific permit rule or fee for this, so don't guess, call the city directly. If the dumpster sits fully on private property, driveway or yard, permitting is less likely to apply, but that assumption still needs a quick check against your specific address. Our dumpster permit requirements page walks through what to ask when you call. Delivery trucks also need roughly 60 feet of straight clearance behind the unit to place it safely, so measure your driveway or curb space before scheduling. Guadalupe sits about 3.5 miles southwest of Tempe Junction, and jobs out that way follow the same rule: confirm placement locally, every time, rather than relying on what worked at a different address.
Why does contamination cost extra on a dumpster rental?
Because sorting a mixed load by hand takes labor and time, and that gets billed back to you. A single battery, propane tank, or gallon of paint mixed into a load can trigger a contamination fee on top of your rental charge, sometimes exceeding the original weekly rate of $600 for a dumpster rental. Landfills that accept loads from this region inspect bins before processing, and flagged loads get returned or resorted at your cost. It's cheaper to separate hazardous items yourself and dispose of them through a dedicated facility. If your job also produces liquid waste, like grease from a food truck or event kitchen, that's a different stream entirely: see grease trap pumping rather than trying to dump it. For septic or holding tank waste generated on a job site, septic pumping service handles that safely, and it should never end up in a roll-off.

What happens if I put a banned item in my dumpster by accident?
Call us right away. We can often pull the item before pickup if you catch it early, avoiding a contamination charge. After pickup, the landfill's inspection determines the fee, and it gets added to your final invoice. Check dumpster rental cost for how these fees typically break down.
Are paint cans really not allowed in a roll-off?
Correct, wet or liquid paint is treated as hazardous waste in most disposal streams. Dried, empty cans are usually fine, so let cans dry out fully with the lid off before tossing them. When in doubt, set them aside and ask us directly rather than guessing.
Can I throw away a refrigerator or air conditioner?
Not in a standard roll-off. Appliances holding refrigerant need special handling because of the gas inside, and most landfills reject them outright without documentation that the refrigerant was removed. Ask us about a separate pickup option for large appliances.
What about yard waste and dirt?
Small amounts of yard waste are usually fine, but dirt, sod, and green waste in bulk add serious weight fast. See dumpster weight limits before filling a bin with soil, since a load that looks half full can still hit the ton limit.
Do event dumpsters have different rules than construction ones?
Not really, the banned list stays the same. Events tend to generate more mixed recycling and food waste rather than hazardous material, so contamination risk is usually lower. Pair your bin with event restroom rental for a full site setup.
