Renting a Dumpster for Large Construction or Demolition Projects


Before renting a roll-off dumpster for your next large construction or demolition project, you have to consider the type of materials you’re working with, the volume of debris you’ll accumulate, duration of the project and availability of your dumpster. If you can plan at least a few of these factors out, you will reduce your rental cost by being prepared. 

For example, if you have a large job that ideally needs three 40-yard dumpsters, but you can only find a company with six 20-yard dumpsters, you are going to end up paying more for the smaller ones because you will end up needing twice as many.

Here’s a few numbers to associate with the above example based on nationwide dumpster rental pricing:

Dumpster Size

Average Cost

10 yards


20 yards


30 yards


40 yards


Generally, it is more cost effective to rent the biggest dumpster available that is suitable for the amount of debris you are generating at your job site. If the larger dumpster could prevent you from needing a second or third dumpster, you could save a few hundred dollars on disposal costs. 

How Much Debris will I generate?

A critical estimate to make is determining how much debris you think you will generate during your project. If you have an idea of that number, then choosing the correct dumpster size will be easier. The Federal Emergency Management Agency (FEMA) uses the following basic formula to estimate debris:

Building Demolition: Length x Width x Height x 0.33 / 27 = Cubic Yards of Debris 

Single-Family Home Demolition: Length x Width x S x .20 x VCM = Cubic Yards of Debris

S = number of stories

VCM = vegetative cover multiplier, or yard waste

For reference, one ton of construction and demolition debris equals about 2 cubic yards.

High density, low volume debris like shingles or concrete, is best disposed of in smaller dumpsters instead of a 40 yard dumpster. 

Planning Benefits for Dumpster Rentals

Although you may have an accurate idea of how big your dumpster needs to be, there are some more planning aspects that will make your rental experience smooth for you and the dumpster company that you shouldn’t forget to consider.

  • BE EFFICIENT: Talk to your dumpster rental company about all details of the dumpster delivery, pick-up and swap-out processes. Make sure you are clear about your disposal needs and schedule so you can reduce or eliminate any delays or misunderstandings in the process.
  • BE SAFE: Dispose of all of your debris immediately in the dumpster instead of piling it up to maintain a safer job site. Always make sure safety on the job site is a top priority by maintaining a clean work environment as you complete the job. 
  • BE PREPARED: Estimate the number of total dumpsters you will need to finish the job, and account for container swap-outs or live-loading as a part of the removal. Before booking a dumpster, make sure the company can meet your needs. If you don’t ask, you won’t know. 

Hopefully these considerations will help you for your next large construction or demolition job.
