How Big Is a 20 Yard Dumpster?
A 20 yard roll-off runs about 22 feet long, 8 feet wide, and 4 to 5 feet tall on the walls, though exact dumpster dimensions 20 yard units vary a little by manufacturer. That footprint holds enough volume for a full construction dumpster rental on a mid-size remodel or a whole-house declutter. If you're between sizes, compare it against a 10 yard dumpster rental for smaller jobs, a 20 yard dumpster rental for mid-size loads, or a 30 yard dumpster rental for framing and demo debris. Full specs across the lineup live on dumpster sizes and dimensions. Every roll-off delivery needs about 60 feet of straight clearance behind the truck, so check your driveway or alley in Boulder before booking. Tight lots near older Boulder neighborhoods sometimes need street placement instead, which raises the permit question below, and a look at the porta potty placement guide can help if you're siting a restroom on the same lot.
What Does a 20 Yard Dumpster Cost in Boulder?
Pricing depends on rental length, not just size. Here's what a 20 yard roll-off dumpster rental typically runs:
| duration | low | typical | high |
|---|---|---|---|
| day | 51 | 75 | 112 |
| week | 426 | 600 | 778 |
| month | 91 | 108 | 500 |
Delivery is usually billed separately, and a day-rate delivery fee typically falls between 100 and 500 dollars depending on distance and access. For a full rundown of what drives the number up or down, see dumpster rental cost and the general porta potty rental cost guide for combo bookings with restrooms, or check roll-off dumpster rental for the wider lineup. If your load is mostly heavy material like concrete or shingles, ask about dumpster weight limits before you fill it, since overage fees aren't in this table.
Do I Need a Permit for a 20 Yard Dumpster in Boulder?
That depends on where the dumpster sits. Placement in the public right of way, meaning on a street or city sidewalk rather than on your own driveway, needs confirming with the City of Boulder before delivery. We can't quote a specific ordinance number here because permit rules vary by placement and haven't been verified for this page. If you're planning a driveway drop only, you likely skip the permit question entirely, though it's worth a quick read of porta potty permit requirements too if restrooms share the same spot. For anyone renting near Valmont, 3.5 miles east of Boulder, or out toward Louisville, 9.4 miles southeast, the same right-of-way question applies with that jurisdiction instead. Full detail on what's allowed and what to ask sits on dumpster permit requirements, and the broader construction site services page covers how dumpsters, fencing and restrooms get scheduled together. Loading a chute or enclosure at a job site also falls under OSHA 1926.252 for waste disposal, and general site housekeeping is covered by OSHA 1926.25, both worth knowing if you're running a crew rather than a solo cleanout.
Pair the dumpster with sanitation if you've got workers on site: OSHA 1926.51(c) sets toilet counts by crew size on construction jobs, and a standard porta potty rental alongside your dumpster covers that requirement in one call. Bigger crews or longer jobs might prefer a monthly porta potty rental billed on the same schedule as the dumpster, and sites needing ramps or crowd routes can add a temporary fence rental to keep the lot organized.
What can't go in a 20 yard dumpster?
Paints, solvents, tires, batteries and most hazardous liquids are excluded from standard roll-off loads. Check the full list on what cannot go in a dumpster before you load, since violations can mean a rejected pickup or an extra fee.
How long can I keep a 20 yard dumpster?
Day, week and month terms are all available, and Boulder customers most often book by the week for remodel timelines. Monthly rates run lower per day than short-term rentals, so a longer job usually costs less overall than repeated short pulls.
Can I combine a dumpster with a porta potty order?
Yes, most Boulder job sites order both together. A single delivery run for a portable toilet rental and a roll-off saves a separate delivery fee and keeps one point of contact for service.
Is a 20 yard dumpster big enough for a roof tear-off?
Usually, for roofs up to about 3,000 square feet with asphalt shingles. Larger or multi-layer tear-offs often need a 40 yard dumpster rental instead, so measure your roof area first.
What if I need the dumpster same day?
Same-day and rush delivery is sometimes possible depending on route and truck availability that day. Call ahead and ask, since the emergency porta potty rental team can often coordinate a rush dumpster drop on the same trip.
