How many units does my job actually need?
Start with warm bodies, not guesswork. OSHA 1926.51(c) sets the construction ratio at 1 toilet for 20 workers or fewer, then 1 toilet seat and 1 urinal per 40 workers once you pass 20. Farm crews fall under a different rule: OSHA 1928.110 calls for one facility per 20 hand-labor employees, reachable within a quarter mile walk, which matters for farm and agricultural restrooms spread across a large parcel. Events run on a looser standard, closer to one unit per 75 to 100 guests depending on alcohol and food service. If you are staffing a wedding, check wedding restroom rental guidance before you lock a number. For a full breakdown by crew size or guest count, the how many porta potties do I need guide walks the math step by step, and OSHA portable toilet requirements covers the construction side in more depth than a checklist can. Undercounting is the single most common mistake, and it is the one that gets a site written up.
What ADA and accessibility items belong on the list?
Check for at least one accessible unit before delivery day, not after. ADA Standards section 213.2 requires that where single-user portable toilets are clustered, at least 5 percent must be accessible units, with one as the floor even on a small job. That unit needs a 60 inch turning circle per section 304.3.1, a clear route at least 36 inches wide under section 403.5.1, and a door opening of at least 32 inches under section 404.2.3. Ground under and leading to the unit has to be stable, firm and slip resistant per section 302.1, which rules out loose gravel or soft turf as a pad. Reach ranges matter too: operable parts need to sit within the 48 inch high, 15 inch low reach zone under section 308.2.1, and latches must work with one hand and no more than 5 pounds of force per section 309.4. Full detail lives on ADA accessible porta potty and ADA restroom requirements if your job needs more than one accessible station.

Where and how should units be placed on site?
Placement decides whether service runs smooth or turns into a weekly fight with a truck that cannot get close enough. A roll-off or pump truck needs about 60 feet of straight clearance behind it to work, so plan the pad with that in mind before delivery, not after the unit is sitting in the wrong spot. Ground should be level and firm, since a standard unit runs about 44 by 48 inches on the ground and stands roughly 92 inches tall, and a full standard porta potty rental tips easily on soft or sloped soil. If the unit sits anywhere near a public sidewalk or street in Salt Lake City, placement in the right of way needs confirming with the city; check porta potty permit requirements before you finalize a spot rather than after. The full porta potty placement guide covers wind exposure, foot traffic flow and distance from food service. Winter jobs carry their own placement issues, covered on porta potty in winter, since freeze risk changes where a unit can safely sit.

Do I need a permit before I order?
Permit status belongs at the top of the checklist, not the bottom, because it can change your delivery date. Placement within the public right of way needs confirming with the city, and Salt Lake City permitting rules are not something to guess at over the phone. The dumpster permit requirements page covers the roll-off side of this same question if your job also needs a container, and porta potty permit requirements walks the toilet-specific version. Handwashing is a separate line item: 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at any station, and hand sanitizer alone does not satisfy that rule, so if your permit or inspector asks about handwashing, a handwashing station rental or portable sink rental needs to be on the order, not assumed. If the job involves paint, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) requires washing facilities for that contaminant exposure specifically, which is a different trigger than general sanitation.
| unit | duration | typical price |
|---|---|---|
| standard | day | $150 |
| standard | week | $200 |
| standard | month | $200 |
| ada | week | $185 |
| dumpster | week | $600 |
Rates above sit inside measured ranges; full detail lives on porta potty rental cost and porta potty rental per day. Long jobs should also compare monthly porta potty rental against week-to-week pricing before committing. Salt Lake City crews running jobs out toward South Salt Lake, 7.9 miles south, or Murray, 11.6 miles south, should confirm delivery windows early since drive time affects service scheduling.
How often should a standard unit get serviced?
ANSI/PSAI Z4.3 sets the baseline at one service visit per week for up to 10 users over a 40 hour week. Heavier events or larger crews need more frequent pumping. See how often are porta potties cleaned for how that scales with headcount.
What is the difference between a standard unit and a deluxe unit?
A standard unit is a basic 60 to 70 gallon tank on a fixed base. A deluxe flushable porta potty adds a flush mechanism and sink, usually for events or longer-term crew comfort where a hand-crank spigot is not enough.
Can I rent for just a weekend?
Yes. Weekend rentals exist specifically for short events and typically run higher per day than a weekly rate, since the crew handles delivery and pickup within 48 to 72 hours. Ask about weekend pricing directly when you request a quote.
Do I need a permit for a residential driveway rental?
Maybe. A unit sitting entirely on private property, off any sidewalk or street, usually has fewer restrictions than one near a right of way. Confirm with Salt Lake City directly since placement rules vary by exact location.
What happens if my septic tank backs up during a renovation?
Call for emergency service. A residential septic tank is typically pumped every 3 to 5 years depending on tank size and household size; a sudden backup outside that window often signals a full tank or blockage needing prompt attention. See emergency septic service for response details.
