What size dumpster do I need for a cleanout or remodel?

Pick the size by two things at once: how much space the debris takes up and how much it weighs. For most home cleanouts and single-room remodels a 20-yard roll-off is the usual choice. A whole-house cleanout or a large renovation usually needs a 30-yard, and a 40-yard is for big remodels and construction jobs. Heavy debris such as concrete, dirt and roofing goes in a smaller box, because it reaches the weight limit long before it fills the space.

The sizes you will be offered

A "yard" here is a cubic yard of space. WM's Richmond rental page lists 20-yard, 30-yard and 40-yard roll-off containers.^[1] Its 20-yard box measures 7 feet wide, 3 feet 6 inches high and 21 feet 11 inches long, and its 30-yard box is the same footprint at 5 feet 2 inches high.^[1] WM rates them at about 8, 14 and 16 pickup loads, lists 10 tons for each size, and includes a 7-day rental.^[1] Other haulers, especially local ones, also rent 10- and 15-yard boxes, and their sizes and allowances can differ, so ask for the exact dimensions and weight allowance of the box you are being quoted.

WM describes the 20-yard as ideal for heavy-debris home clean-outs and remodeling cleanup, the 30-yard for large home renovation projects or junk removal, and the 40-yard for large construction and large remodeling projects.^[1]

Match the size to the job

These are starting points, not rules. Your house, your debris and your hauler's allowances decide the final answer.

• Garage, attic or basement cleanout: a 10- or 20-yard box, depending on how full the space is. Furniture and boxes are bulky but light.
• One bathroom or a small kitchen: a 10- or 20-yard box. Tile, plaster and cabinets add weight fast.
• A large kitchen or several rooms: a 20- or 30-yard box.
• A whole-house cleanout or a full renovation: a 30- or 40-yard box, or more than one haul.
• Concrete, brick, soil or a roof tear-off: a small box, often 10 yards, filled only partway with the heavy material. Shingles from a roof are best left to the roofer, who usually arranges the container as part of the job.

The quickest way to estimate is in pickup-truck loads. Picture how many full beds of debris the job would fill and compare that with the hauler's own figures.

Weight matters as much as volume

Every quote includes a weight allowance, and debris weighs very different amounts for the same space. EPA's volume-to-weight table puts mixed construction and demolition debris at 417 pounds per cubic yard,^[2] so a full 20-yard box of it would weigh about twenty times that, a little over four tons.^[2] The same table lists concrete at 860 pounds per cubic yard, dirt and sand at 929, asphalt roofing at 731, gypsum board at 467 and clean dimensional lumber at 169.^[2] For a cleanout, uncompacted mixed residential, institutional and commercial trash runs 250 to 300 pounds per cubic yard.^[2]

That is why a hauler will often put dirt or concrete in a small box. Ten yards of dirt at that rate is ten times 929 pounds, more than four tons,^[2] while a large box of furniture and cardboard rarely gets near its limit. If your job mixes both, ask whether a separate small load of the heavy material costs less than one big overweight box.

Measure the spot before you book

WM's 20- and 30-yard boxes are 21 feet 11 inches long,^[1] and the truck that drops it needs more room than that to back in and tilt its bed. Before you book, measure the driveway or yard, look up for low wires and branches, and check for soft ground, septic lines or a thin driveway the truck would have to cross. Many homeowners lay boards under the container's rails to spread the load on a driveway; ask the hauler what it suggests. If there is no room on your property, the container goes on the street, and that usually needs a permit. See whether you need a permit to put a dumpster on the street in Virginia.

Where the debris goes, and what that costs

A roll-off is usually the simplest way to move remodel debris because local drop-off sites often will not take it. Montgomery County's consolidated sites do not take construction or demolition waste, including renovation and remodel waste, and say some unacceptable items may be taken to the Montgomery Regional Solid Waste Authority.^[3] There, the Authority's 2026-2027 rates, effective July 1, 2026, charge $53.00 per ton for construction waste and $76.00 per ton for household municipal solid waste.^[4] Fees like these, at whichever landfill or transfer station your hauler uses, are a large part of what you pay for extra weight. For how the price is put together, see how much it costs to rent a dumpster in Virginia.

Some things should not go in the box at all, whatever its size. See what you can't put in a dumpster in Virginia before you start loading.

Stop and call a pro if

• The debris includes old flooring, ceiling texture, pipe insulation or siding you suspect contains asbestos. EPA says you generally cannot tell whether a material contains asbestos just by looking at it, that remodeling can disturb such materials, and that if in doubt you should treat it as asbestos and leave it alone.^[5]
• The project means taking down walls, a deck, a roof or another structure. That is contractor work, and the contractor usually sizes and orders the container.
• The only place for the container is a steep driveway, a soft lawn or a busy street.
• You find the job is far bigger than one container, such as a hoarded house or a full estate. A cleanout crew can sort, donate and haul in one visit.
