30 Yard Dumpster Rental in Concord, CA
Short answer: a 30 yard roll-off costs $765 with 3 tons included and measures 18 by 7.5 by 6 feet. It holds around 150 garbage bags or 9 pickup loads, and it is the container we bring for demolition and estate clearing across Concord.
Everything below the 30 gains capacity mostly through length. This container gains it through height. Six foot walls instead of four and a half is what lets cabinetry, framing and furniture go in whole, without the labour of breaking material down to fit a shorter box.
That changes the economics of a demolition job. The cost of a crew cutting debris into smaller pieces, or waiting on a second delivery, is almost always higher than the $150 step up from a 20 yard.
Volume Is the Point, Not Weight
Three tons sounds generous until the material is dense. Thirty squares of composition shingle runs close to 3.75 tons on its own, and a load of plaster or tile reaches the ceiling with the walls half empty. On those jobs the extra height is capacity you cannot legally use, and a 10 yard or the flat rate container costs less.
Where the 30 earns its price is bulk: kitchen cabinets, closet systems, framing lumber, mattresses, office furniture and cleared vegetation. All of it fills space quickly and weighs very little relative to the volume it occupies.
Access Matters More at This Size
Eighteen feet of container needs a straight approach and roughly 60 feet of clearance. On narrow lots, shared driveways and hillside streets in Concord and Walnut Creek, that is the constraint that decides the size rather than the debris.
We ask about gate width and turning room before dispatching a 30, because a truck that cannot place the container still costs a trip. If access is tight, two 15 yard deliveries often solve the job at a similar total price, since a 15 needs only 12 feet.
Estate Clean-Outs Are the Other Common Job
Alongside demolition, a full estate clean-out is the other job that reliably fills a 30 yard: decades of furniture, appliances that still work but nobody wants, boxes of belongings sorted room by room. Unlike a single-room remodel, that kind of job rarely produces dense debris, which is exactly why the height matters more than the weight allowance here.
Commercial and Multi-Day Work
On builds that run for weeks, the 30 is usually rented on a swap schedule rather than a single haul. You call, we pull the full container and drop an empty on the same visit, so the crew never stops. Rentals run from 1 to 21 days, and swaps are scheduled on request rather than on a fixed route day.
