What size dumpster do I need in Spokane?
Short answer: three roll-off sizes serve Spokane, and most home projects land on the 20 yard. The 16 yard is the one that fits a tight driveway, and the 30 yard is for a full remodel or a whole-house clear-out.
Below are the real dimensions, what each box is rated to hold, how much room it needs on your property, and how the rental window works. If you would rather not load it yourself at all, compare with full-service junk removal.

What are the roll-off dumpster sizes in Spokane?
Sixteen, twenty, and thirty cubic yards. The differences that matter are footprint and wall height, not volume alone.
| Size | Dimensions | Rated capacity | Best fit |
|---|---|---|---|
| 16 yard | About 12 ft long, 8 ft wide, 6 ft high | Fits 8 loads | Construction job sites and placement in tight spots |
| 20 yard | About 22 ft long, 8 ft wide, 4 ft high | Fits 10 loads | The popular size for medium to large projects |
| 30 yard | About 22 ft long, 8 ft wide, 6 ft high | Fits 15 loads | Major cleanouts, remodeling, large-scale construction |
Dimensions, capacities, and fit descriptions above are the dumpster operator's own published specifications for the Spokane roll-off line.
Why is the 20 yard longer but shorter than the 16?
Because they are shaped for different problems. The 16 yard is short and tall: it packs volume into a small footprint, which is what a cramped driveway or a tight job site needs. The 20 yard is long and low, and those four-foot walls are the reason it is the popular one. You can walk a broken vanity or a stack of drywall over the side instead of lifting it above your head. The 30 yard is the 20 yard's footprint with the 16 yard's wall height, which is how it gets to fifteen loads.
If you are throwing heavy, awkward things over the side by hand all weekend, wall height will matter more to you than an extra few yards of capacity.
Which size fits your project?
Most people overthink this. Two questions settle it: how much, and how much room do you have.
When is the 16 yard the right call?
When space is the binding constraint rather than volume. A narrow city driveway in Browne's Addition, a shared alley, a lot where the box has to sit beside the house instead of in front of it. It is also the operator's stated fit for construction job sites, where a compact footprint keeps the work area usable. If your project is a single-room gut, a bathroom, or a roof section on a small house, the volume is usually there.
When is the 20 yard the right call?
Most of the time, for most Spokane homeowners. Garage and basement clear-outs, a kitchen tear-out, a deck removal, a multi-room decluttering, a roof on an average house. It is described by the operator as the popular size for medium to large projects, and the low walls are why. If you genuinely cannot decide between the 16 and the 20, and the driveway will take the length, the 20 is the safer miss.
When is the 30 yard the right call?
Whole-house cleanouts, a full remodel running across several rooms, an estate clear-out, or large-scale construction. Also the right answer any time the alternative is renting a smaller box twice, because a swap costs you a second delivery, a second pickup, and a gap in the middle of the project where there is nowhere to put anything.
What if you guess wrong?
Under-sizing is the more expensive mistake. An overfilled box cannot be legally hauled, so material has to come back out before it moves, which is the one part of this that genuinely wastes a day. Over-sizing costs you footprint on the driveway. Given the choice, describe the project honestly on the phone and let the operator size it: they have loaded a few thousand of these and you have loaded one.
How much room does a roll-off dumpster need?
More than the box itself, because the truck has to get it off and back on.
The box is eight feet wide, so plan on a clear lane wider than that. Length is the part people miss: a 20 or 30 yard box is roughly 22 feet, and the truck needs clearance in front of it to slide the container off the rails and to winch it back up on pickup day. Overhead matters too, because the truck's arm goes up well past the height of the box. Low branches, a carport, and utility lines running across the driveway are the three things that turn a routine delivery into a phone call.
- Clear the placement area of cars, bikes, and anything that cannot be moved quickly.
- Look up before you decide the spot. Branches and service lines are the usual obstruction.
- Think about the side you will load from and leave yourself working room on it.
- Plywood under the wheels is a common way people protect a driveway surface.
- Decide on the spot before delivery day so the driver is not guessing.
How fast can a dumpster be delivered in Spokane?
The operator's published answer is within a day or two, with same-day delivery available. On the back end, pickup is aimed at within one business day of your call. The rental window itself is flexible, running from 7 days to several months, so a slow weekend purge and a full kitchen tear-out both fit without racing a clock.
Do you need a permit to put one on the driveway?
On your own property, typically not, though local rules and neighborhood associations can have their own requirements. Street placement is a different question with a real city process behind it, and it is covered on the Spokane dumpster permit page.
What can you put in a Spokane roll-off dumpster?
Most of a house and most of a job site, with the same chemical exclusions as any hauler.
The operator's stated list covers most household items, construction debris, yard waste, and some appliances. Practically, that means furniture, carpet, drywall, lumber, cabinetry, roofing tear-off, brush, fencing, and general clutter all belong in the box.
What does not belong is the same short list that keeps items off a hauling truck: paint and solvents, motor oil, pesticides, propane cylinders, car batteries, and anything with asbestos in it. Those go to a household drop-off, and the reasoning plus destinations are on the what junk removal cannot take page. Load the heavy flat material first and low, keep the load level with the top rail, and the pickup goes without a conversation.
