How many porta potties do I need for a construction site?
OSHA 1926.51(c) sets the baseline: 1 toilet facility for 20 workers or fewer, then 1 toilet seat and 1 urinal per 40 workers once you pass 20, and 1 seat and 1 urinal per 50 workers at 200 or more on site. A 12-person crew in Port Saint Lucie needs one unit. A 45-person crew crosses into the next bracket and needs two. Bigger commercial jobs scale from there. Most contractors renting standard porta potty rental units budget on a weekly basis since crews stay put for months, and pricing runs by the week rather than daily turnover. If your crew works with paint, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) kicks in separately and requires washing facilities beyond what the toilet count covers, which is where a handwashing station rental earns its keep. Field crews in agriculture follow a different rule entirely: OSHA 1928.110 requires one facility per 20 hand-labor employees, reachable within a quarter mile walk, which matters for the citrus and row-crop operations west of the city. Check OSHA Portable Toilet Requirements for the full bracket table before you order.
How many porta potties do I need for an event?
Event math runs off headcount and hours, not worker brackets. A rough guide: one unit per 50 guests for events under 4 hours with no alcohol, tightening to one per 35 to 40 guests once beer or wine is served, since drinks mean more bathroom trips per person. Multi-day festivals need service scheduled between days, not just more units sitting idle. A 300-person wedding reception in Port Saint Lucie running 6 hours with a bar typically lands around 8 to 10 standard units, or fewer if you upgrade to a restroom trailer rental with multiple stalls. Golf outings, fun runs and church festivals all scale differently, so check Event Restroom Rental or the specific guides for Wedding Restroom Rental, Festival Restroom Rental, and Marathon and Race Restrooms before locking a number. Standard event pricing typically falls in the 200 to 800 dollar range depending on unit count and duration, per the measured event rate band.
| headcount | duration | alcohol | units |
|---|---|---|---|
| 50 | 4 hours | no | 1 |
| 100 | 4 hours | no | 2 |
| 150 | 6 hours | yes | 4 to 5 |
| 300 | 6 hours | yes | 8 to 10 |
What adjustments do I make for alcohol or multi-day events?
Alcohol adds roughly 30 to 40 percent more bathroom trips per guest, so tighten your ratio from one per 50 down to one per 35. Multi-day events need a service visit built into the plan, not an afterthought. ANSI/PSAI Z4.3 sets the baseline service interval at once per week for up to 10 users over a 40-hour week, which works fine for a single-day event but breaks down fast over three or four days with hundreds of guests. A weekend festival in Port Saint Lucie running Friday through Sunday should plan on at least one mid-event service call, sometimes two if the crowd is large. Weekend rates for standard units run higher than a single weekday because of that extra handling, so ask your vendor to confirm timing before the gates open. If your event needs an accessible unit, ADA Standards section 213.2 requires at least 5 percent of clustered single-user units to be accessible, never fewer than one, so a 10-unit event needs at least one ADA accessible porta potty on-site regardless of headcount math.
How many cubic feet are in a 10 yard dumpster?
A 10 yard dumpster holds about 270 cubic feet of debris, roughly matching a small bathroom gut or a garage cleanout. Physically it runs about 12 feet long and around 6 feet wide, which is why people asking "how many feet is a 10 yard dumpster" usually mean the footprint on their driveway, not the volume. It's the smallest size most companies stock and it's the right call for single-room renovations. Pair it with a porta john rental if the crew's on site more than a day or two. Full dimensions and weight capacity are broken down on Dumpster Sizes and Dimensions, and pricing sits in the daily-to-monthly bands covered on Dumpster Rental Cost.
How many tons does a 20 yard dumpster hold and how many feet is it?
A 20 yard dumpster holds roughly 3 tons of mixed debris and runs about 540 cubic feet, with a footprint close to 16 feet long. That's the size most kitchen remodels and mid-size roof tear-offs land on. Weight limits vary by material, heavier for shingles and concrete, lighter for bulky low-density trash, so check Dumpster Weight Limits before loading it past the rim. Renting a 20 yard dumpster rental alongside a temporary fence rental is common on residential jobs where a work zone needs to stay separated from the rest of the yard. A roll-off delivery needs about 60 feet of straight clearance behind the truck, so measure your driveway or street access before booking.
How many tons does a 30 yard dumpster hold, and what about a 40?
A 30 yard dumpster holds around 4 to 5 tons and roughly 810 cubic feet, while a 40 yard dumpster holds close to 5 to 6 tons and about 1,080 cubic feet. Those two sizes cover most whole-house cleanouts, large renovations, and new construction debris in Port Saint Lucie. The 30 yard dumpster rental is the workhorse for roofing and framing jobs, while the 40 yard dumpster rental suits commercial demolition and big landscaping clears. Neither size belongs on a residential street without checking clearance and weight rules first, and materials like concrete or dirt fill the weight limit long before they fill the box, which is covered in more depth on What Cannot Go In a Dumpster. Construction crews running both a dumpster and a toilet on the same site should read Construction Site Services for how the two get scheduled together.
Do I need an accessible unit on my site or event?
Yes, if you're clustering multiple single-user units. ADA Standards section 213.2 requires at least one accessible unit, and at least 5 percent of the total once you scale past a handful. An accessible unit needs a 60 inch turning circle per section 304.3.1, a 32 inch clear door opening per section 404.2.3, and a stable, firm, slip-resistant surface underneath per section 302.1. Weekly rental for an ADA unit runs in a lower band than daily rates scaled out, which matters for jobs lasting more than a few days. Most Port Saint Lucie job sites and public events need at least one regardless of total headcount, so build it into the count from the start rather than adding it after the fact. Full compliance detail lives on ADA Restroom Requirements and ADA Accessible Porta Potty.
Where do I start if I am not sure what my job needs?
Start with headcount and duration, then match it against the OSHA bracket or event ratio above. A 15-person renovation crew working two weeks in Port Saint Lucie needs one standard unit and probably a small dumpster; a 400-person festival needs a mixed fleet of standard units, at least one ADA unit, and a service schedule built around the event's length. If the job's near the coast, crews working out of Jensen Beach or Stuart sometimes combine orders since both towns sit within 15 miles.

How many porta potties do I need for 100 guests?
Two units minimum for a 4-hour event without alcohol, three if drinks are served. Longer events or hot Florida afternoons push people toward the units more often, so err toward the higher count if the party runs past 4 hours.
How many porta potties does OSHA require for a 30-person crew?
One toilet facility per 20 workers or fewer, then one seat and one urinal per 40 workers past that under OSHA 1926.51(c). A 30-person crew crosses into the next bracket and typically needs two units.
How many tons does a 30 yard dumpster hold on a roofing job?
Around 4 to 5 tons, though shingles are dense and can hit that weight limit before the box looks full. Ask your hauler about per-ton overage charges before loading heavy tear-off material.
Do I need more porta potties if alcohol is served?
Yes. Alcohol increases bathroom frequency, so tighten your ratio from one unit per 50 guests down to about one per 35. Multi-hour events with an open bar should plan on the higher end.
How many cubic feet does a 40 yard dumpster hold?
About 1,080 cubic feet, roughly double a 20 yard box. It suits large demolition and commercial cleanouts more than typical residential jobs.
Can I rent one accessible unit for a small event?
Yes. ADA Standards section 213.2 requires at least one accessible unit regardless of total count, so a small event with just two or three standard units still needs one ADA-compliant unit included.
