How many porta potties do I need?
Start with your headcount and the hours worked. OSHA 1926.51(c) sets the baseline for construction crews: one toilet for 20 workers or fewer, then a toilet plus urinal for every 40 workers once you pass that mark, scaling down to one per 50 at 200 or more. Farm crews fall under a different rule; OSHA 1928.110 requires field sanitation facilities within a quarter mile walk, one per 20 hand-labor employees. Events run on a different math entirely, driven by guest count and how long the bar stays open. The full breakdown, with worked examples, lives on our porta potty count guide. If you are still guessing between a couple of standard units and a small restroom trailer, get a headcount first, then call. Pomona job sites with tight parking often do better with two units on opposite ends than four bunched together, and that spacing choice belongs on your checklist too, not just the total number.
What permit do I need for placement in Pomona?
Confirm placement in the public right of way with the City of Pomona before you commit to a spot; check with the city on any right-of-way or sidewalk closure. That is not verified block by block on this page, so treat it as a phone call, not an assumption. If your unit sits entirely on private property, set back from the curb, permitting is usually simpler, but the city still has final say. Our permit requirements page walks through what to ask when you call, and the placement guide covers ground clearance and access. Roll-off deliveries need their own look: a dumpster truck needs about 60 feet of straight clearance behind it to set the box down, which matters on narrow Pomona streets or shared driveways. If you are running a construction dumpster alongside your toilets, check both placements in the same call so the crew is not moving trucks twice.
What ground and access does the unit need?
Flat, stable ground matters more than people expect. ADA Standards 302.1 calls for surfaces that are stable, firm and slip resistant, and that standard is a good bar for any unit, not just accessible ones. A standard unit runs about 44 by 48 inches on the ground and stands roughly 92 inches tall, so measure your spot before delivery day, not after. If you are placing an ADA unit, the route to it needs a 36 inch clear width under ADA Standards 403.5.1, the door opening itself needs 32 inches clear under ADA Standards 404.2.3, and the unit needs a 60 inch turning circle inside per ADA Standards 304.3.1. Where you cluster several portable restrooms at one Pomona site, ADA Standards 213.2 requires at least 5 percent of the cluster, and never fewer than one, to be accessible. Check overhead clearance too. Trees, power lines and low awnings are the most common reason a Pomona delivery gets rescheduled.
Do I need handwashing or water service too?
Depends on the job. OSHA 1926.51(a)(1) requires an adequate supply of potable water at any place of employment, and 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at wash stations, not hand sanitizer alone. If your crew is applying paint, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) kicks in specifically for that work, requiring washing facilities beyond the general rule. A standalone handwashing station or portable sink covers both cases cheaply, and pairing one with your toilet order is usually simpler than adding it later. For food service or catering at a Pomona event, a grease interceptor also needs attention on the back end; it gets pumped once fats, oils, grease and solids reach 25 percent of the liquid depth, which is worth flagging to your caterer, not just your restroom vendor. See handwashing requirements for the full list, and grease trap pumping if food waste is part of your event.
| unit | day | week | month |
|---|---|---|---|
| standard | 100-350 | 130-500 | 125-325 |
| ada | 200-400 | 120-240 | - |
| deluxe | 85-1200 | 150-290 | - |

How far ahead should I book for a weekend event in Pomona?
Book 3 to 5 days ahead for a standard weekend order. Weekend rates for a standard unit run higher than a weekday day rate, so lock your count early. Trailers and ADA units have fewer units in rotation, so those need more lead time than a basic porta john.
Can I place a unit on the street in Pomona?
Only with the city's sign-off. Right-of-way placement is not something to assume; call the City of Pomona and confirm before delivery day. Private-property placement, set back from the curb, is generally the easier path and skips that call entirely.
What size clearance does a dumpster delivery need?
About 60 feet of straight clearance behind the truck, so it can set the box down without backing through tight turns. Check your driveway or alley length against that before scheduling a roll-off dumpster alongside your toilets.
Does a portable toilet rental include handwashing?
Not automatically. Many standard units are a toilet only, so add a hand sanitizer station or a full handwashing unit if your job involves food, paint or medical work covered under OSHA's washing rules.
How often does a septic tank need pumping compared to a rental unit?
A residential septic tank typically needs pumping every 3 to 5 years, based on tank and household size. Rental units get serviced weekly under the ANSI/PSAI Z4.3 baseline instead, since they see continuous public use rather than one household's flow.
