What Is a Standard Porta Potty?
It is the plain box you picture when someone says porta potty. No sink, no flush handle, just a holding tank and a door that locks. A standard unit measures about 44 by 48 inches on the ground and stands roughly 92 inches tall, so it fits tight side yards and job site corners without eating much space. Inside sits a 60 to 70 gallon holding tank, enough for steady use across a week between services under the ANSI/PSAI Z4.3 service interval, which sets one visit a week as the baseline for up to 10 users over a 40 hour week. That is the standard porta potty size and shape you will see on almost every construction site services job and plenty of backyard parties around Alameda. If you need something nicer for a wedding or a company picnic, look at the deluxe flushable porta potty instead, and if a guest uses a wheelchair, an ADA accessible porta potty is the right call, not a standard unit. Some folks call it a porta john rental, others just say portable toilet rental. Same box, different name.
How Much Does a Standard Porta Potty Rental Cost?
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | $100 | $150 | $350 |
| Weekend | $125 | $250 | $400 |
| Week | $130 | $200 | $500 |
| Month | $125 | $200 | $325 |
| Event | $200 | $400 | $800 |
Basic porta potty rental cost depends on how long you keep the unit and where it sits on the island. A single-day rental for a driveway project costs less than a week on an active job site, and a month-long rental for a remodel crew usually beats booking four separate weeks. Most delivery fees land between 100 and 500 dollars for a day rental, and 120 to 420 dollars if you are renting monthly, so ask what is included before you compare two quotes side by side. For a deeper breakdown of what drives standard porta potty rental prices up or down, see our porta potty rental cost page, or check porta potty rental per day if you only need one for a Saturday. Longer jobs should look at monthly porta potty rental instead of renewing weekly.
How Many Standard Porta Potties Do I Need?
For construction crews, OSHA 1926.51(c)(1) sets the baseline: one toilet for 20 workers or fewer, then one toilet seat and one urinal per 40 workers once you pass 20, and one per 50 once the crew hits 200 or more. A five-person framing crew in Alameda needs one unit. A 45-person crew building out a warehouse near the estuary needs two. For farm labor jobs, OSHA 1928.110 requires one facility per 20 hand-labor employees, reachable within a quarter mile walk, plus potable water under OSHA 1926.51(a)(1). Events run differently. Plan on more units per guest than a job site because everyone shows up in the same two-hour window instead of spreading use across a shift. Run the numbers with our how many porta potties do I need guide before you book, especially if you are also renting a temporary fence rental or a light tower rental for the same site and need to plan the whole footprint at once.
Where Can I Place a Standard Porta Potty in Alameda?
Placement rules in Alameda are not fully settled in this guide, and putting a unit in the public right of way needs confirming with the city before delivery day. What we can tell you: keep the ground level and stable, since a tipped unit is a mess nobody wants, and leave clear walking space so ADA Standards section 403.5.1's 36 inch clear route guidance is easy to meet if the site also needs an accessible unit. If you are staging a roll-off dumpster rental or a storage container rental on the same lot, plan porta potty placement around truck access, because a delivery truck needs roughly 60 feet of straight clearance behind it to drop a roll-off cleanly. Our porta potty placement guide covers ground surface, doorway swing and neighbor sightlines in more detail. Renovation jobs inside Alameda's older housing stock often need the unit close to the curb but off the sidewalk, so measure twice before the truck shows up. If your event or job also needs temporary power pole service or a handwashing station rental, coordinate all three deliveries together to save on separate trip charges.
Frequently asked questions
What is the difference between a standard and a deluxe porta potty?
A standard unit has no sink and no flush, just a seat over a 60 to 70 gallon tank. A deluxe flushable porta potty adds a flush mechanism and hand sanitizer, and it costs more per day. Choose standard for job sites, deluxe for weddings or office parties where guests expect more.
How often does a standard porta potty get serviced?
Weekly service is the baseline under ANSI/PSAI Z4.3 for up to 10 users over a 40 hour week. Busy job sites or events with heavier traffic need more frequent pumping. Ask your provider to match the service schedule to your actual headcount, not just the calendar.
Do I need a permit for a porta potty in Alameda?
Placement permitting is not confirmed in our records, so check with the City of Alameda before delivery if the unit sits near a sidewalk or street. Private property placement, like a backyard or a fenced job site, is usually simpler. See our porta potty permit requirements page for what to ask when you call.
Can I rent a standard porta potty for just a weekend?
Yes. Weekend rentals for a standard unit typically run higher per day than a full week booking but lower than a single scattered day rate, since the provider is only making one delivery and one pickup trip. Piedmont and Emeryville customers 10 to 12 miles north book the same weekend rate structure we offer in Alameda.
What size crew needs more than one standard porta potty?
Once a construction crew passes 20 workers, OSHA 1926.51(c)(1) calls for a second toilet seat and a urinal, scaling further at 40 and 200 workers. Event crowds need units figured differently, based on guest count and event length rather than shift size. Use how many porta potties do I need to size it right the first time.
