For a construction crew, OSHA 1926.51(c) sets the baseline: 1 toilet for up to 20 workers. For an event, plan on 1 unit per 50 guests for a 4-hour event, more if you're serving alcohol or running past 6 hours. Gardena Porta Pros builds every quote around your headcount, your hours and your site.
Start with your crew size, then check it against OSHA 1926.51(c): 1 toilet seat for 20 workers or fewer, 1 toilet seat plus 1 urinal per 40 workers once you're between 20 and 200, and 1 seat plus 1 urinal per 50 workers at 200 or more. A 15-person framing crew in Gardena needs one standard porta potty rental. A 75-person crew crosses into the second bracket and needs roughly two seats and two urinals, which usually means two standard units plus a urinal-equipped unit or a small bank of them. Bigger commercial jobs, the kind running near West Rancho Dominguez 3.1 miles east, often mix in a handwashing station rental since OSHA 1926.51(a)(1) requires potable water at the site regardless of toilet count. If your crew is spraying paint, coatings, herbicides or insecticides, 1926.51(f)(1) kicks in separately and calls for washing facilities beyond a sink with sanitizer, since 29 CFR 1910.141(d)(2) specifically excludes hand sanitizer as a substitute for soap and towels. Check our OSHA portable toilet requirements guide before you finalize a headcount, and see construction site services if you're bundling toilets with a dumpster.
| guests | duration | units |
|---|---|---|
| 50 | 4 hours | 1 to 2 |
| 100 | 4 hours | 2 to 3 |
| 250 | 4 hours | 4 to 6 |
| 500 | 6 hours | 8 to 10 |
These are starting ranges, not fixed rules. A wedding of 150 guests running 5 hours in Gardena typically lands at 3 to 4 standard porta potty rental units, or step up to a deluxe flushable porta potty for a nicer feel near the ceremony. If alcohol is served, add roughly 1 extra unit per 100 guests since bathroom trips run more frequent and longer. Multi-day festivals need a service plan on top of unit count: ANSI/PSAI Z4.3 sets a baseline service interval of once per week for up to 10 users over a 40-hour week, which is far too infrequent for a weekend crowd, so expect daily servicing built into your quote. For weddings specifically, see wedding restroom rental, and for larger festival counts, festival restroom rental walks through staging and generator needs.
Yes, if you're clustering portable toilets for public use. ADA Standards section 213.2 requires that at least 5 percent of clustered single-user units be accessible, with a minimum of one no matter how small the cluster. That means even a 3-unit event setup in Gardena needs one ADA accessible porta potty. The accessible unit has to sit on a stable, firm, slip-resistant surface under ADA 302.1, with a 60 inch turning circle inside per ADA 304.3.1 and a 32 inch clear door opening under ADA 404.2.3. Approach paths matter too: ADA 403.5.1 calls for a 36 inch clear route to the unit, and any ramp needed to reach it can't exceed a 1:12 slope under ADA 405.2. Job sites with any public-facing component, not just events, should default to including one. Full detail lives on our ADA restroom requirements page.
One standard unit almost always covers a single-family renovation crew of 1 to 5 people. Homeowners doing a kitchen remodel or an addition in Gardena usually rent for the length of the permit, often several weeks, which makes a monthly porta potty rental cheaper per day than repeated short bookings. If the crew is just 2 to 3 people for a bathroom gut, a weekly rental through porta john rental or straight portable toilet rental covers it without paying for capacity you don't need. See home renovation porta potty for placement tips specific to residential lots, where driveway space and neighbor sightlines usually decide the spot more than headcount does.
Dumpster size depends on debris volume, not toilet count, but the two get ordered together constantly. So how many feet is a 10 yard dumpster and how many cubic feet does it hold? A 10 yard dumpster runs about 12 feet long, which answers how many feet is a 10 yard dumpster, and holds roughly 2,700 cubic feet, which answers how many cubic feet in a 10 yard dumpster, good for a single-room cleanout. A 20 yard dumpster is about 22 feet long, holds close to 5,400 cubic feet, and answers how many tons does a 20 yard dumpster hold with roughly 2 to 3 tons before hitting weight limits. A 30 yard dumpster holds around 8,100 cubic feet and answers how many tons can a 30 yard dumpster hold with roughly 3 to 4 tons depending on material density. A 40 yard dumpster holds about 10,800 cubic feet, which answers how many cubic feet in a 40 yard dumpster, and answers how many tons does a 40 yard dumpster hold with roughly 4 to 5 tons. Heavier debris like concrete or shingles hits the weight ceiling long before the volume fills, so check dumpster weight limits before you order. Full breakdowns of each size sit at 10 yard dumpster rental, 20 yard dumpster rental, 30 yard dumpster rental and 40 yard dumpster rental, with dimensions compared side by side on dumpster sizes and dimensions.
Yes. A one-day event and a three-day festival with the same headcount need different plans, because units fill up and servicing has to keep pace. ANSI/PSAI Z4.3 treats once-weekly servicing as baseline for light use, but a multi-day event with hundreds of daily guests needs at least daily service, sometimes twice daily for units near food or bar areas. Budget for that service frequency, not just the initial unit count, when you request a quote. Overnight camping events near Gardena should also plan lighting: OSHA 1926.56(a) sets minimum illumination levels for work areas, and while that standard targets job sites, event organizers use the same logic for safe nighttime paths to restrooms. Pair your restroom order with a light tower rental if the event runs past dusk. For race-day or endurance events spread across a course, see marathon and race restrooms, and for golf outings with hole-by-hole placement, golf tournament restrooms.
Take a 300-guest outdoor event running 6 hours with beer service, roughly 6.7 miles from Hermosa Beach on the coast-facing side of Gardena. Start at the 250-guest bracket of 4 to 6 units, then add one unit for the extra 50 guests and one more for alcohol, landing at 7 to 8 standard units. Add one ADA accessible porta potty to satisfy the 5 percent minimum under ADA 213.2. If the event has a VIP or bridal area, swap one or two standard units for a deluxe flushable porta potty or step up to a compact restroom trailer rental like a 2 stall restroom trailer. Add a handwashing station rental near any food service. Once you've got a working number, check porta potty rental cost or porta potty rental per day to price it out, and confirm placement against the porta potty placement guide before delivery day.
Plan on 2 to 3 standard units per 100 guests for a 4-hour event. Add units if alcohol is served, if the event runs longer, or if there's a big gap between food service and restroom placement. A short kids' event needs fewer than an adult party with a bar.
A 30 yard dumpster typically carries around 3 to 4 tons, though it depends heavily on what's inside. Mixed construction debris fills the volume before it hits the weight cap. Dense material like concrete, brick or roofing shingles hits the weight limit fast, often well before the container looks full.
A 20 yard dumpster holds close to 5,400 cubic feet of volume. It runs about 22 feet in length. That size covers a mid-size renovation, a roof tear-off, or a garage cleanout without needing a second pull.
Yes, add roughly one extra unit per 100 guests. Alcohol increases bathroom frequency and trip length, and lines form fast once the bar opens. Events running past dark should also budget lighting near the restroom bank so guests aren't navigating a dark path after a few drinks.
As long as your project needs, from a single weekend to several months. Short jobs work fine on a daily or weekly rate, but permitted renovations running multiple weeks usually save money on a monthly porta potty rental instead of restarting a weekly contract.
Yes, that's standard practice. Most job sites and events use a mix of standard porta potty rental units for general use and add an ADA accessible porta potty to meet the 5 percent minimum under ADA 213.2, keeping the accessible unit on a stable, level surface with a clear approach path.
