What Are the Dumpster Sizes and Dimensions in Seattle, WA?
Picking the right box comes down to footprint and height, not just yardage. Ten yard dumpster measurements land around 12 by 8 by 3.5 feet, the smallest box we roll out and a good fit for a garage cleanout or a bathroom remodel. Move up to 20 yard dumpster measurements and you are looking at roughly 22 by 8 by 4.5 feet, the size most Seattle homeowners land on for a kitchen tear-out or a deck demo. Dumpster sizes 20 yard also cover midsize roofing jobs where shingles pile up fast. A 30 yard dumpster size keeps the same 22 by 8 footprint but climbs to about 6 feet of wall height, built for framing debris and whole-house cleanouts. If you are unsure which one fits your driveway or your alley, our dumpster sizes and dimensions guide is the pillar page behind this one, and our roll-off dumpster rental page walks through delivery basics for the whole city.
How Much Space Does a 10 Yard Dumpster Need?
A 10-yard dumpster dimensions footprint is small, but the truck delivering it is not. Seattle Porta Pros needs about 60 feet of straight clearance behind the truck to set the box down safely, which matters on narrow streets in Capitol Hill or Ballard where parking is tight. Ten yard dumpster sizes work well for single-room renovations, yard debris after a windstorm, or clearing out a rental unit between tenants. If your alley or driveway cannot give the truck a straight shot, check our porta potty placement guide for the same sightline logic we use on toilets, or call ahead so we can plan the approach. Homeowners doing a bathroom gut job usually pair a 10 yard box with a standard porta potty rental if the house water gets shut off mid-project. For pricing across sizes, our dumpster rental cost page breaks down day, week, and month rates side by side.
What Fits in a 20 Yard Dumpster?
Twenty yard dumpster measurements make this the workhorse size for mid-scale jobs: a full kitchen remodel, a garage teardown, or several rooms of flooring and drywall. At 22 feet long and about 4.5 feet high, it holds more volume than the 10 yard without adding footprint length, since both share roughly the same base. Contractors running a job inside Seattle often pair a 20 yard box with construction dumpster rental service and a temporary fence rental around the work zone, especially near sidewalks where OSHA 1926.25 requires debris cleared from work areas regularly. If you are not sure whether 10 or 20 yard fits your scope, our dumpster sizes and dimensions comparisons and our 10 yard dumpster rental and 20 yard dumpster rental pages lay out the difference project by project.
Why Does a 30 Yard Dumpster Cost More Than a 20 Yard?
A 30 yard dumpster size holds more debris in the same footprint by adding height, not length, which means hauling weight climbs fast and that drives price. Dumpster dimensions 30 yard come in at 22 by 8 by roughly 6 feet, a foot and a half taller than the 20 yard. That extra volume is why weekly rates for larger boxes run higher across our measured pricing, and why weight limits matter more on a 30 yard than a 10. Our dumpster weight limits page explains what pushes a box over its cap, and 40 yard dumpster rental covers the largest option if your teardown outgrows even a 30. Debris chutes and enclosures on multi-story demo work fall under OSHA 1926.252, worth knowing if your crew is dropping material from height into the box.
Do I Need a Permit for a Dumpster in Seattle?
Yes, in most cases. Seattle requires a Street Use permit from the Seattle Department of Transportation before a dumpster sits in the public right-of-way, under SMC 15.04.010, which makes it unlawful to use a public place without written permission from the Director of Transportation or another named authority. SDOT's placement rules for containers in the right-of-way require them to sit in a legal parking spot, stay free-standing, and keep clear lines of sight: at least 30 feet from intersections, 10 feet from driveways, and 15 feet from fire hydrants. If your box sits entirely on private property, a driveway or a private lot, this requirement may not apply, but check with SDOT before delivery day. Full detail lives on our dumpster permit requirements page and our porta potty permit requirements page covers the same right-of-way logic for toilets.
| dumpster size | length | width | height | typical use |
|---|---|---|---|---|
| 10 yard | 12 ft | 8 ft | 3.5 ft | single room, small cleanout |
| 20 yard | 22 ft | 8 ft | 4.5 ft | kitchen remodel, roofing |
| 30 yard | 22 ft | 8 ft | 6 ft | framing debris, whole-house cleanout |
Renting for a full week or longer usually costs less per day than a short one or two day rental, so if your project in Seattle runs past a weekend, ask about weekly rates before booking daily. See our dumpster rental cost page for the full pricing table across sizes and durations.
Whether you are working a job site 8.9 miles southeast toward Mercer Island or closer in near downtown, delivery clearance and permit rules stay the same across the city. Pair your dumpster with a portable restroom rental if crews are on-site all day, and check what cannot go in a dumpster before loading anything questionable, since certain materials can void the rental or trigger extra fees.
What size dumpster do I need for a kitchen remodel?
Most kitchen remodels fit a 20 yard dumpster, which handles cabinets, countertops, and flooring debris without needing the taller 30 yard box. If you are also demoing walls or replacing subflooring, size up. Our 20 yard dumpster rental page has more scope-specific guidance.
Can a 30 yard dumpster fit in a residential driveway?
Usually, yes, since the footprint matches a 20 yard box at 22 by 8 feet. The difference is height, not length, so if a 20 yard fits your driveway, a 30 yard will too. Confirm delivery clearance with roll-off dumpster rental.
How is dumpster yardage measured?
Yardage measures cubic volume, not weight. A 10 yard box holds 10 cubic yards of debris, calculated from its length, width, and height. Heavier materials like concrete or shingles fill the weight limit before the volume limit, which our dumpster weight limits page explains.
Is a permit required for a dumpster on a Seattle street?
Yes, placement in the public right-of-way needs an SDOT Street Use permit under SMC 15.04.010. Placement entirely on private property may not require one, but confirm with SDOT first. See dumpster permit requirements for details.
What is the difference between a 10 yard and 20 yard dumpster?
The 20 yard is nearly double the length, 22 feet versus 12 feet, with more height too. A 10 yard suits single-room jobs; a 20 yard handles multi-room remodels or roofing tear-offs. Compare both on dumpster sizes and dimensions.
