How Many Dumpsters Are Needed to Demolish a House?

Updated June 24, 2025

How many dumpsters are needed to demolish a house? The number of roll-off dumpsters required for house demolition varies based on the size of the home and the materials used. On average, demolishing a single-family home requires between three and eight 40-yard dumpsters. Factors like square footage, wood vs. brick construction, and presence of heavy materials, like concrete or roofing, all impact the dumpster estimate. Understanding this helps homeowners estimate demolition costs more accurately and avoid overpaying for debris disposal.

Here is a rough estimate of how many 40 yard dumpsters it will take to dispose of common-size houses that are conventionally framed...

**How Many Dumpsters Does House Demolition Require?**
House Size	Amount of Debris	# of 40-yard Dumpsters
1,000 sq. ft.	135 cubic yards	4
2,000 sq. ft.	270 cubic yards	7
3,000 sq. ft.	405 cubic yards	11

How Many Dumpsters Are Needed to Demolish a 2,000 Square Foot House?

Demolishing a typical 2,000 sq. ft., two-story stick-built, or conventionally framed, house will generate approximately 245 cubic yards of debris, not including the concrete foundation or yard waste. This usually requires six to seven 40-yard dumpsters or eight to nine 30-yard dumpsters.

Factors That Affect the Number of Dumpsters Needed

Size and number of stories
Wood vs. brick construction
Basement vs. slab foundation
Salvaging materials before demolition
Additional debris (concrete, trees, etc.)

Formula for Estimating Demolition Debris Volume (Cubic Yards)

(Length × Width × Height × 0.33) ÷ 27 = Total cubic yards of debris

Here's an example...

House Dimensions = 40 ft (L) × 25 ft (W) × 20 ft (H)

Estimated Debris Volume = (40 × 25 × 20 × 0.33) ÷ 27 = 244.4 cubic yards

How Many Dumpsters You'd Need for 244.4 Cubic Yards:

Dumpster Size	Debris Capacity	Estimated Dumpsters Needed
30 yard	~30 cubic yards	8-9 dumpsters
40 yard	~40 cubic yards	6-7 dumpsters

Note: Does not include foundation concrete or green waste.

Let's take a more detailed look at how many dumpsters a typical stick-built 2,000 sq. ft. house will require...

Keep in mind that, because all houses are different, your exact results may vary considerably, but regardless of how big your house is, you'll have to consider the size of the general structure, the roofing materials, the foundation, and any surrounding green waste.

First, let's calculate how many cubic yards of construction and demolition (C&D) debris the home will have from materials like wood, siding, roofing, lathe or drywall, and other miscellaneous components making up the home.

Here, we are looking at only debris from the home. We're not including the concrete foundation and any tree canopy or green waste to remove. Those will be calculated separately.

Calculating the cubic yards of demolition debris is simple and involves converting the cubic footage of the structure to cubic yards, while also accounting for the air space in the building (0.33).

For our 2,000 square foot house example, let's assume our home is two (2) stories and the dimensions are 40 feet x 20 feet.

The formula and calculations are:

(Length (ft) x Width (ft) x Height (ft) x 0.33) ÷ 27 = cubic yards of demolition debris

So our house example's formula would be: (40 ft L x 25 ft W x 20 ft H x 0.33) ÷ 27 = 244.4 cubic yards of debris

To get the number of dumpsters needed for this portion of the debris, we divide our roughly 245 cubic yards of debris by the cubic yard capacity of the dumpster...

245 cubic yards of debris ÷ 30 cubic yard dumpster ≈ 8 dumpsters
245 cubic yards of debris ÷ 40 cubic yard dumpster ≈ 6 dumpsters

For the C&D debris in our 2000 sq ft house demolition example, you would likely need eight to nine 30 yard dumpster loads or six to seven 40 yard dumpster loads. This does not include dumpsters for the concrete foundation or green waste.

How Many Dumpsters Are Needed for a Concrete Foundation?

Removing the concrete slab from a 2,000 sq. ft. home will generate approximately 25 cubic yards of concrete debris, or roughly 50 tons. Because of concrete’s extreme weight, this debris typically requires 14 or more 10-20 yard dumpsters, depending on the dumpster's weight capacity and the hauler's equipment.

Why Concrete Is Calculated Separately

Concrete must be hauled in dedicated dumpsters (aka "clean concrete" loads). These cannot be mixed with wood, drywall, or other demolition debris because:

Recycling centers may accept clean concrete at a lower cost than landfills
Landfills often reject concrete or charge high fees
Hauling limits (both legal and mechanical) restrict how much weight can be placed in one container

Slab Foundation Calculation Example

To estimate concrete debris volume...

Formula:

(Length × Width × Thickness) ÷ 27 = Cubic yards of concrete

For a 40 ft × 25 ft slab, 8 inches thick (0.67 ft)...

(40 × 25 × 0.67) ÷ 27 = 24.8 cubic yards of concrete

Weight of Concrete Debris

1 cubic yard of concrete ≈ 4,000 lbs

25 cubic yards × 4,000 lbs = 100,000 lbs (50 tons)

Most haulers cannot pick up a 30- or 40-yard dumpster filled with this much concrete. It’s too heavy for the truck and may exceed road weight restrictions, so it will require multiple dumpsters to complete the job.

Dumpster Requirements for Concrete

Dumpster Size	Weight Limit (Capacity)	Estimated Loads
10 yard	~4,000-6,000 lbs	~15-25 loads
15 yard	~5,000-8,000 lbs	~12-20 loads
20 yard	~6,000-10,000 lbs	~10-15 loads

Concrete removal typically requires around 15 or more dumpsters, depending on size and local hauling limits.

Hauling Tip: Always check with your dumpster rental company. Not all haulers can manage heavy loads of concrete, and the lifting mechanism on the truck (e.g., hook-lift or cable) needs to match the weight you're disposing of.

Let's take a more detailed look at how many dumpsters average concrete foundation removal requires...

The number of dumpsters needed for the concrete foundation should be calculated separately from the other house demolition debris. The concrete should be in separate loads so it can be recycled.

A "clean concrete" load (dumpster containing only concrete) can be dumped at the concrete recycler rather than the landfill, so don't mix other debris in with the concrete. Some landfills will not accept concrete, and dumping concrete at a recycler is generally much cheaper than the cost to dump at a landfill.

The average foundation is somewhere between 8 and 10 inches thick.

For our example, we'll assume 8 inches (.67 ft) and that our 2,000 sq. ft. home was built on a slab. If you have a basement or crawl space, you'll need to calculate the floor and the four concrete walls separately (same formula for each section), and then add it all together.

Concrete slab foundation

(Length (ft) x Width (ft) x Height (ft)) ÷ 27 = cubic yards of debris

So our foundation example's formula would be: (40 ft L x 25 ft W x 0.67 ft H) ÷ 27 = 24.8 cubic yards of concrete debris

Because concrete is so heavy, you won't be able to fill up a single 30 yard dumpster with 25 cubic yards of concrete. The concrete debris will weigh over 50 tons, and the hauler will never be able to pull the dumpster up onto the truck. It's just too heavy. There are also weight restrictions on the roads that would be problematic.

Concrete weighs about 4,000 lbs per cubic yard. So, in our example... roughly 25 cubic yards of concrete debris x 4,000 lbs/cubic yard = 100,000 lbs, or 50 tons of concrete.

Dumpster rental companies' ability to pick up and haul very heavy loads of concrete varies considerably, so be sure to ask your hauler about the capabilities of their truck and hook lift system that pulls the dumpster up onto the truck.

A 40 ft. x 30 ft. concrete slab foundation that is 8 inches thick would produce 50 tons of concrete to remove. At least fifteen 10-yard dumpsters or ten 20-yard dumpsters would be required, depending on their weight limit.

How to Account for Green Waste During House Demolition

If your home is surrounded by trees that will need to be removed prior to demolition, this is something that you’ll need to take into account. Generally speaking, the best way to handle tree removal is to hire a tree removal specialist prior to demolition. They will then haul off the yard waste or convert the wood to chips on-site.

If the demolition provider will be removing any nearby trees or yard waste during the demolition process, you will need to include this in your estimates for cubic yards of debris and the total number of dumpsters necessary to haul it away.

A common way to do this is by using what’s called a vegetative cover multiplier (VCM). Developed by FEMA, it accommodates for the vegetative debris, or green waste, that will be included in the demolition of a home within a subdivision or neighborhood.

For new home developments where more ground is visible than trees and canopy cover is thin, VCM = 1.1
For homes that have an equal amount of open space and canopy cover, VCM = 1.3 (Most common)
For homes found in mature neighborhoods or the canopy cover completely covers the ground/home, VCM = 1.5

Tip: If you're not using a tree removal company, double-check that the dumpster service will haul green waste. Most will... but green waste generally can't be mixed with other types of waste. The entire load must be a 'clean load' of only yard waste...no general trash or other demo debris.

How Weight Limits Affect the Price of Disposal

Dumpsters, and the trucks that haul them away, have weight limits. Wood, lathe, concrete, and other demolition debris is very heavy. So, when comparing pricing from dumpster services, consider the amount of included weight for the price. The more generous the weight allowance, the lower your overall disposal cost will be.

The chart below can help you roughly understand the weight of common types of demolition debris per cubic yard.

**Weight of Common Demolition Debris per Cubic Yard**
Material	Lbs/Cubic yd	Notes
Burned debris/ash	800-1,000 1,500-1,800 2,300	Loose/dry Wet for dust suppression Wet mixed with soil
Asphalt or concrete	2,400
Wood, un-compacted	400	Increase up to 100% if compacted using heavy machinery
Metals, un-compacted	600	Ex. appliances, metal siding
Earth	2,100 3,000	Loose/dry. Increase 30% if compacted Excavated/wet
Gravel or crushed stone	2,600	Increase 20% if wet
Standard red clay bricks	3,400

Here are some examples of "included weight" for general construction debris:

10 yard dumpsters: 2,000-4,000 lbs (1-2 tons)
20 yard dumpsters: 4,000-6,000 lbs (2-3 tons)
30 yard dumpsters: 8,000-10,000 lbs (4-5 tons)
40 yard dumpsters: 12,000-16,000 lbs (6-8 tons)

Note: These are examples of included weight. Each company's weight limits are different, so be sure to check with your dumpster provider. And know what happens when your dumpster exceeds the weight limit. What is the additional cost per ton of additional weight?

How to Determine a Dumpster Provider's Availability

For any significant demolition project, the hired dumpster service will need to be available for multiple trips back and forth to the landfill or recycling center.

The dumpster company will deliver a container (or more in some cases) to the site of your intended demolition. You then fill up the dumpster, and the company loads it onto their truck, hauls it to the landfill/recycling facility, empties the container, and brings it back to the demo site, repeating this process until all the debris is gone.

Plan ahead so the dumpster company can dedicate a truck or two to your job for part or all of a day.
