Key Takeaways
- • 15-yard: garage cleanouts, bathroom remodels, medium landscaping projects
- • 20-yard: full kitchen/bath renovations, shed demolitions, estate cleanouts
- • Dumpster prices are rental only — you load it
- • When in doubt, choose the 20-yard to avoid running out of space
Ordering the wrong dumpster size is the most common mistake we see. Go too small and you're paying for a second pickup and redelivery. Go too big and you're paying for space you didn't use — though that's the better of the two problems.
This guide breaks down the sizes we currently offer for dumpster rental in Chicagoland, what fits, what doesn't, and how to pick the right one for your project.

When to use each size
15-Yard Dumpster
The most popular size for suburban homeowners. Handles most single-project cleanouts comfortably.
- ✓ Garage cleanout — typical 2-car garage
- ✓ Kitchen or bathroom renovation debris
- ✓ Medium deck (150–250 sq ft) demolition
- ✓ Basement cleanout (moderate amount)
Step up to a 20-yard if: garage is packed floor-to-ceiling or you're adding basement items.
20-Yard Dumpster
The contractor's standard for mid-size renovations and larger property cleanouts.
- ✓ Estate cleanouts — whole-house clearing
- ✓ Full kitchen and bath renovation combined
- ✓ Large shed or garage demolition
- ✓ Roofing projects (1,500–2,000 sq ft home)
- ✓ Construction debris removal from remodel
Call us if your job is larger than a 20-yard rental — we can recommend the right next step.

The two most common sizing mistakes
Ordering too small is the more expensive mistake. If your 15-yard fills up halfway through the job, you're paying for the pickup, then paying for a new delivery. The small step up to a 20-yard often beats a redelivery fee.
Ordering too big costs a bit more upfront but gives you the flexibility to add "one more thing" without stress. Empty air in a dumpster is far cheaper than overflow charges or a second trip.

Frequently asked questions
What size dumpster do I need for a garage cleanout?
A 15-yard handles most garage cleanouts. For a garage packed floor-to-ceiling, or if you're adding basement or attic items, a 20-yard gives comfortable room.
How much does a dumpster rental cost in Chicagoland?
Dumpster rental only is $450 for a 15-yard and $495 for a 20-yard. You load it; junk removal labor is separate. Overweight fees apply if debris exceeds the weight limit.
Can I put roofing shingles in a roll-off dumpster?
Yes — shingles are allowed but heavy. A full square of architectural shingles weighs ~350 lbs. For a roofing project, always discuss weight expectations with us before booking to get the right container and avoid overweight fees.
