    What Size Dumpster Do I Need? A Miami Homeowner's Guide

    Published 2026-06-18

    10, 20, 30, and 40-yard dumpsters explained for Miami homeowners. What fits in each size, permit notes for Miami-Dade, and how to pick the right one.

    Why size matters more than you think

    Picking the wrong dumpster costs you money either way. Too small and you pay for a second haul or a swap-out mid-project. Too big and you pay for space you never fill. Most homeowners overestimate what they need because they picture everything spread across the garage floor. Once it goes into a dumpster, it compresses. Here is what each size actually holds and when to use it.

    10-yard dumpster

    • Dimensions: roughly 12 ft long, 8 ft wide, 3.5 ft tall.
    • Holds about 3 pickup truck loads.
    • Best for: a single bathroom remodel, a small deck tear-out, a garage cleanout that is mostly boxes and light furniture.
    • Not enough for: anything involving drywall from more than one room, or any job with concrete or tile.
    • This is the most common size for a single-room project where you are doing the demo yourself over a weekend.

    20-yard dumpster

    • Dimensions: roughly 22 ft long, 8 ft wide, 4.5 ft tall.
    • Holds about 6 pickup truck loads.
    • Best for: a kitchen gut, a full roof tear-off (single layer, under 2,000 sq ft), a medium estate cleanout, or a garage plus shed cleanout combined.
    • This is the workhorse size. If you are not sure, this is probably the one. About 60% of our residential rentals are 20-yard.

    30-yard dumpster

    • Dimensions: roughly 22 ft long, 8 ft wide, 6 ft tall.
    • Holds about 9 pickup truck loads.
    • Best for: a whole-house cleanout (3+ bedrooms of furniture and junk), a large renovation with mixed debris, or a major landscaping overhaul with dirt and brush.
    • At this size you need to think about weight. Miami-Dade disposal facilities charge by ton, and 30 yards of construction debris gets heavy fast. We will tell you if a weight-based surcharge is likely before you book.

    40-yard dumpster

    • Dimensions: roughly 22 ft long, 8 ft wide, 8 ft tall.
    • Holds about 12 pickup truck loads.
    • Best for: new construction cleanups, commercial build-outs, large multi-unit cleanouts, or full gut renovations of a house.
    • Residential driveways sometimes cannot fit a 40-yard. Measure first: you need at least 60 feet of straight clearance for the roll-off truck to drop it. If it has to go on the street, you need a permit.

    Miami-Dade permit and placement notes

    If your dumpster sits on your own driveway or property, no permit is needed. If it has to go in the street or on the swale (the strip between the sidewalk and the curb), Miami-Dade County requires a right-of-way permit. The city of Miami has its own process on top of the county one. We handle the paperwork, but it adds 1 to 3 business days, so plan ahead. Also: Miami-Dade prohibits placing dumpsters within 10 feet of a fire hydrant or blocking a sidewalk. HOAs often have their own restrictions on top of that, and some ban dumpsters entirely. Check with your association before booking.

    FAQ

    Can I mix different types of debris in one dumpster?

    Yes, for most materials. You can mix furniture, drywall, wood, metal, and general junk in a single container. The exceptions are dirt, concrete, and roofing shingles, which are heavy and priced by weight. Mixing heavy material with light junk means you pay the heavy rate for the whole load. If you have a lot of concrete or dirt, ask us about a separate heavy-debris container.

    How long can I keep a dumpster?

    Standard rental is 7 days. Extensions are available for ongoing projects, usually in 7-day increments. If your project wraps up early, call us and we will pick it up sooner at no extra charge.

    What happens if I fill it past the top?

    The load cannot extend above the rim of the container. It is a safety and DOT regulation: the truck cannot legally haul an overloaded dumpster on public roads. If material is above the rim when we arrive, we will either need to remove the excess or bring a second container.

    Do I need to be home for delivery and pickup?

    No. As long as the placement spot is clear and accessible, we can drop off and pick up without you there. Just make sure cars, hoses, and basketball hoops are out of the way.
