What size dumpster do I need?
Start with the job, not the yardage. A garage cleanout or small landscaping job usually fits a 10 yard dumpster rental, while a kitchen remodel or roofing job in South San Francisco tends to fill a 20 yard dumpster rental fast. Bigger construction jobs, additions, or whole-house cleanouts push toward a 30 yard dumpster rental or a 40 yard dumpster rental. Weight matters as much as volume: heavy debris like concrete or shingles can hit the truck's limit before the box looks full, so check dumpster weight limits before you load. If you're not sure what goes in the box at all, what cannot go in a dumpster covers the common rejects. For a driveway or tight lot, a roll-off delivery needs about 60 feet of straight clearance behind the truck, which rules some units out before size even enters the conversation.
10 yard dumpster measurements
10-yard dumpster dimensions typically run around 12 feet long, 8 feet wide and just over 3 feet tall for 10 yard dumpster sizes, though exact dimensions vary by manufacturer. That footprint fits most driveways in South San Francisco without blocking a garage door or a neighbor's access. It's the right call for a single-room cleanout, a small deck demo, or yard debris after a trim job. If you're doing a home renovation porta potty job alongside the dumpster, the two often get delivered together to save a trip. For pricing on this size and others, see dumpster rental cost. Homeowners near San Bruno, 5.5 miles southwest of South San Francisco, often start with this size for a single-story remodel before deciding they need to size up mid-project.
20 yard dumpster measurements
Step up to a 20 yard dumpster and you're looking at roughly 22 feet long, 8 feet wide and about 4.5 feet tall, again depending on the manufacturer's build. This is the size most contractors default to for a kitchen gut, a bathroom remodel, or a mid-size cleanout in South San Francisco. It holds noticeably more than the 10 yard without needing much more clearance on-site, though you still want that same straight shot for the delivery truck. If the job is ongoing rather than one-and-done, ask about a monthly porta potty rental to pair with it, since most remodel jobs need both a dumpster and a toilet on-site for the crew. Construction crews working sites that also require sanitation should check OSHA portable toilet requirements and OSHA 1926.51(c), which sets toilet counts at one facility for 20 or fewer workers.
30 yard dumpster size
Dumpster dimensions 30 yard generally measure around 22 feet long, 8 feet wide and closer to 6 feet tall, the added height doing most of the work over the 20 yard box. This size handles roofing tear-offs, major renovations, or a full interior demo where volume piles up fast. It needs more room to maneuver, so confirm your access matches what a roll-off dumpster rental truck needs before delivery day. Larger commercial and construction projects across South San Francisco, including sites near Burlingame, 7.6 miles south, often run a 30 yard alongside a construction dumpster rental package that bundles fencing and toilets. If the property line or public sidewalk is involved, dumpster permit requirements is worth reading first; placement in the public right of way needs confirming with the city, since South San Francisco's specific rule was not part of what we verified here.
Do dumpster sizes affect price?
Yes. Bigger boxes cost more to rent and to haul, and rental duration changes the math too. A short 10 yard rental for a weekend cleanout costs less than a 30 yard box rented for a month of construction debris. Here's how the bands break down:
| unit | duration | low | typical | high |
|---|---|---|---|---|
| dumpster | day | 51 | 75 | 112 |
| dumpster | weekend | 390 | 440 | 497 |
| dumpster | week | 426 | 600 | 778 |
| dumpster | month | 91 | 108 | 500 |
Delivery fees run separately from the box rental itself, typically landing between 100 and 500 dollars depending on distance and timing. Full detail on how these add up lives on dumpster rental cost. For homes farther out, like Millbrae at 7.2 miles south or Foster City at 15.5 miles southeast, delivery distance can push that fee toward the higher end of the band. Pair this with a porta potty rental cost page if the job needs both.
How much clearance does a roll-off truck need?
A roll-off delivery needs about 60 feet of straight clearance behind the truck to place the box safely. Narrow driveways, low tree branches, or parked cars along the curb in South San Francisco can shrink that space fast, so measure before booking. If your site can't clear that distance, ask about placement options when you call South San Francisco Porta Pros to schedule.
What is the difference between a 20 yard and 30 yard dumpster?
The 20 yard box runs about 4.5 feet tall while the 30 yard adds roughly a foot and a half of height on a similar footprint. That extra volume matters most on roofing and demo jobs where debris is bulky rather than dense. Weight limits still apply either way, so check dumpster weight limits before loading heavy material.
Can I put a dumpster in the street in South San Francisco?
Street placement usually requires checking with the city first, and that specific permit rule was not something we could verify for this page. Read dumpster permit requirements for what we do know, and call the city directly before planning street placement for your project.
What size dumpster fits a typical driveway?
Most residential driveways in South San Francisco handle a 10 or 20 yard dumpster without issue, since both stay under 8 feet wide. Wider driveways or corner lots can sometimes fit a 30 yard box, but the 60 foot clearance behind the truck matters more than driveway width alone.
Do I need a permit for a roll-off dumpster on private property?
Dumpsters placed entirely on private property, like a driveway or yard, typically avoid the permit questions that come with street placement. Confirm this with the city if your lot line is close to the curb. See dumpster permit requirements for related guidance.
