How big is a 20 yard dumpster?
The 20 yard dumpster sits in the middle of the standard roll-off lineup, and the dumpster dimensions 20 yard boxes share across most yards make it easy to compare quotes. Compare it to a 10 yard dumpster rental for small cleanouts or a 30 yard dumpster rental for full renovations, and you can see why contractors default to the 20 for kitchen remodels, garage cleanouts and small roofing jobs. Full dumpster sizes and dimensions, including 20 yard dumpster measurements, are worth checking before you commit, since the wrong size either wastes money or leaves debris piled outside the container. Placement matters too. A roll-off delivery needs about 60 feet of straight clearance behind the truck to set the box down safely, so measure your driveway or alley before scheduling. If you are working a construction site rather than a home job, pair the dumpster with our construction site services and a construction dumpster rental quote covering multiple boxes.
What are the dumpster sizes 20 yard options come in, and what can't go in one?
Across dumpster sizes, the 20 yard 20 yard dumpster size stays a fixed footprint no matter who delivers it, and paint, solvents, tires, batteries and most electronics are off limits, along with anything on our what cannot go in a dumpster list. Overloading is the other common mistake. Every roll-off has a rated capacity, and going over it means the driver cannot legally haul the box; see dumpster weight limits before you fill it with roofing shingles or concrete, which are heavier than general debris by volume. If you're not sure what a 20 yard box costs against other sizes, the dumpster rental cost page breaks down day, week and month pricing side by side.

|---|---|---|---|
| day | $51 | $75 | $112 |
| week | $426 | $600 | $778 |
| month | $91 | $108 | $500 |
Do I need a permit for a dumpster in Seattle?
Likely yes, if the box sits in the public right-of-way. Seattle Department of Transportation requires a Street Use permit for storage containers and residential dumpsters placed in the street, under Seattle Municipal Code 15.04.010, which makes it unlawful to use any public place without written permit approval first. Placement rules require the container to sit in a legal parking space, stay free-standing, and keep clear of intersections, driveways and fire hydrants by set distances. If the dumpster sits entirely on your own driveway or lot, this generally does not apply, but confirm your exact placement with the city before delivery. Full detail is on our dumpster permit requirements page, and the same right-of-way logic applies if you are also renting a storage container rental for the same project.
Seattle homeowners doing a kitchen or bath remodel should also look at our home renovation porta potty page, since most residential jobs need both a dumpster and a restroom on site. If your project sits outside city limits, delivery also reaches Mercer Island 8.9 miles southeast, Shoreline 11.8 miles north and Burien 12.4 miles south.

How long can I keep a 20 yard dumpster?
Rental periods run by the day, week or month, and pricing scales accordingly, with the day rate lowest and the month rate covering extended jobs. Most remodel projects book a week. Confirm your timeline when you request a quote so the pickup date matches your project finish.
What's the difference between a 20 yard and a 30 yard dumpster?
A 20 yard box handles single-room remodels and mid-size cleanouts. A 30 yard dumpster rental suits whole-house cleanouts or larger construction debris. If you're unsure, tell us the project type and square footage and we'll size it correctly.
Can I place a dumpster on the street in Seattle?
Only with an SDOT Street Use permit, since Seattle Municipal Code 15.04.010 prohibits using public right-of-way without one. Driveway or private lot placement usually skips this step. See dumpster permit requirements for the placement rules that apply either way.
Does the 20 yard dumpster work for roofing debris?
Yes, but shingles are heavy. Check dumpster weight limits before loading a full tear-off, since roofing material fills the weight limit long before it fills the box's volume.
How much clearance does delivery need?
About 60 feet of straight space behind the truck for the roll-off to be set down and picked up safely. Narrow alleys or tight driveways in older Seattle neighborhoods sometimes need a site visit first.
