Dumpster Size for a Garage or Basement Cleanout

A cleanout is one of the easiest jobs to oversize a box for, because clutter looks bigger than it hauls. The smart move is the same one a pro makes: sort first, then size the dumpster for what is actually left.

Quick answer: A single-car garage or partial basement purge usually fits a 10-yard dumpster. A two or three-car garage, a full basement, or both together usually calls for a 20-yard, the homeowner favorite. Sort and donate before the box lands and you often drop a full size. See the residential rental options or the cost guide.

Why should you sort before the dumpster shows up?

Sorting first is the single biggest cost lever on a cleanout, and almost nobody does it. Pull the keepers, the donations, the recyclables, and anything sellable before the box lands, and what remains is usually a size smaller than the full pile looked. A weekend of sorting can turn a 20-yard job into a 10-yard job, and that gap is real money on the flat rate.

Here is the order that works. First, set aside anything in good shape for donation: furniture, tools, sporting goods, and working appliances move fast at local thrift and reuse outlets. Second, pull recyclables and scrap metal, which many KC-metro scrap yards will take and some will even pay for. Third, list anything with resale value. Only then do you size the box, because now you are paying to haul trash, not treasure.

What size dumpster fits a typical KC cleanout?

For most homeowners, a 20-yard is the right call, which is why it is our most-rented box across the metro. It swallows a full basement or a packed two-car garage without towering over the driveway. A smaller, single-room purge or a half-garage often fits a 10-yard. The trick is matching the box to the leftover pile after you sort, not the wall-to-wall clutter you started with.

Older homes drive a lot of this work on the Missouri side. The pre-war houses around Brookside and the mid-century stock in Independence have deep full basements that collect decades of stored things. Those are classic 20-yard jobs. Newer tracts in Overland Park and Olathe lean toward big three-car garages, which fill a 20-yard fast once a family decides to clear it out.

What can’t go in a cleanout dumpster?

Garages and basements hide more prohibited items than any other cleanout, so this matters. Paint, motor oil, car batteries, propane tanks, tires, and any appliance holding refrigerant cannot go in the box. Old electronics and household chemicals are usually off-limits too. These need separate disposal, and pulling them out as you sort keeps your pickup from stalling on a load the driver cannot legally haul.

This is exactly why sorting and the box go hand in hand. As you make your donate, recycle, and sell piles, build a fourth pile for the hazardous and prohibited stuff. Most KC-metro cities run periodic household hazardous waste drop-offs for paint and chemicals, scrap yards take the metal and batteries, and tire shops take old tires. Our accepted-debris guide walks through the full list so nothing surprises you on load day.

What does a cleanout dumpster cost in Kansas City?

A residential roll-off for a 7-day rental in the metro usually runs $250 to $450 depending on the size you need, with disposal included up to the tonnage allowance. A 10-yard sits at the low end, around $250 to $350, and a 20-yard usually runs $350 to $450. Both are flat rates: drop-off, pickup, and disposal are built in, so a clean household load rarely hits overage.

Household debris is light compared to roofing or concrete, so most cleanouts stay well under the included tonnage and the volume cap is what matters. A few levers still move the price. Haul distance to the farther suburbs like Blue Springs or Lee’s Summit costs a little more to service, extra days past the week usually run about $10 to $20 each, and a street-placement permit, rarely needed for a driveway drop, usually runs $25 to $100. We give you the all-in number before you book.

Frequently asked questions

What size dumpster do I need for a garage or basement cleanout?

A single-car garage or a partial basement purge usually fits a 10-yard dumpster. A two or three-car garage, a full basement, or both at once usually calls for a 20-yard, which is the homeowner favorite in the metro. Sort and donate first, because the right size depends on what is left after you pull the keepers, sellers, and donations.

Should I sort before the dumpster arrives or just toss everything?

Sort first, every time. Pulling donations, recyclables, and anything sellable before the box lands often drops you a full container size and saves real money. A weekend of sorting can turn a 20-yard job into a 10-yard job. We deliver on your schedule, so plenty of homeowners sort over a week and have us drop the box the day they are ready to load.

What can’t go in a cleanout dumpster?

Paint, motor oil, car batteries, propane tanks, tires, and appliances that hold refrigerant cannot go in the box, and they are common in garages. Old electronics and chemicals are also off-limits in most cases. These need separate disposal, so set them aside as you sort. We will tell you what is prohibited before the drop so nothing stalls your pickup.

How long can I keep the dumpster for a cleanout?

The flat rate covers a 7-day rental, which fits most cleanouts even if you load over a few evenings and a weekend. If your project runs long, extra days usually run about $10 to $20 per day. Cleanouts are a natural fit for a longer window, so tell us your timeline and we will price the rental to match the work.

Will the dumpster fit and not wreck my driveway?

A 10 or 20-yard roll-off fits a standard driveway without taking the whole thing. We place boards under the rails to protect the surface and set the box where you want it, not where it is easiest for us. If access is tight or the drive is new concrete, tell us when you book and we will plan the drop to keep your surface clean.
