Book your delivery date first, then count heads, pick a unit type, and confirm ground access before the truck shows up. A standard unit needs about 44 by 48 inches of ground space, and most Portland deliveries clear in a day. Miss the access check and your delivery gets rescheduled.
Start with headcount and duration, because those two numbers drive everything else on this checklist. If you are building on a job site, OSHA portable toilet requirements apply: OSHA 1926.51(c) sets 1 toilet for 20 workers or fewer, and 1 toilet plus 1 urinal per 40 workers once you pass 20. Agricultural crews fall under a different rule; OSHA 1928.110 calls for one facility per 20 hand-labor employees, reachable within a quarter mile. Next, decide between a standard porta potty rental and a deluxe flushable porta potty, then check whether anyone on site needs an ADA accessible porta potty. ADA Standards section 213.2 requires at least 5 percent of a cluster to be accessible, never fewer than one unit. If this is a backyard project rather than a work crew, home renovation porta potty needs are lighter, but you still want the unit placed before concrete trucks or dumpsters block the driveway.
Pick flat, stable ground with a clear path for the service truck, and settle this before delivery day, not after. A standard unit stands about 92 inches tall and needs level footing so it does not tip in wind off the Willamette. Check the porta potty placement guide for setback distances from doors and windows. ADA Standards section 403.5.1 requires a 36 inch clear route to any accessible unit, and section 304.3.1 calls for a 60 inch turning circle in front of it, so do not wedge an ADA unit into a tight side yard. If you are also renting a roll-off dumpster rental for the same project, remember it needs roughly 60 feet of straight clearance behind the delivery truck, which usually means the dumpster and the toilet cannot share the same curb cut. Confirm whether placement sits in the public right of way; that needs confirming directly with the City of Portland, since we found no verified rule to cite here. For events, pair this with the porta potty rental in Portland hub page for delivery zones near downtown venues.
Match unit count to headcount and rental length before you request a quote, since both change your price. A single standard unit runs in the $100 to $350 per day range depending on duration and add-ons, while a week-long rental for the same unit type runs higher than any single day, and a month runs higher still.
| Unit type | Day | Week | Month |
|---|---|---|---|
| Standard | $100 - $350 | $130 - $500 | $125 - $325 |
| ADA | $200 - $400 | $240 - $400 | - |
| Deluxe | $85 - $1200 | $150 - $290 | - |
Weekend rates for a standard unit run $125 to $400 as a flat block rather than a per-day charge. Delivery itself is usually billed separately, often $100 to $500 for a one-time trip. For exact numbers tied to your job, check porta potty rental cost or porta potty rental per day. Projects running past a month should look at monthly porta potty rental instead of stacking weekly rates. ANSI/PSAI Z4.3 sets the baseline service interval at once weekly for up to 10 users over a 40 hour week, so a crew of 30 will need either more units or more frequent pumping than the baseline covers.
Water and handwashing are separate line items, and OSHA 1926.51(a)(1) requires potable water at every jobsite regardless of restroom setup. If your crew works with paint, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) requires washing facilities beyond the toilet itself, and 29 CFR 1910.141(d)(2) specifies soap and towels or a hand-drying device; hand sanitizer alone does not meet it. A handwashing station rental or portable sink rental covers that gap, and handwashing station requirements walks through the specifics. Check the handwashing station requirements page again if OSHA compliance is the reason you are renting at all. Long-duration projects in Portland should also plan for winter: freezing nights change service intervals, covered in porta potty in winter. If the project includes a septic tank on site rather than a public sewer tie-in, note that a residential tank is typically pumped every 3 to 5 years depending on tank size and household size; see septic pumping service or how often to pump a septic tank for that separate schedule. Sites near Milwaukie or Lake Oswego sometimes combine a toilet order with a temporary fence rental for the same perimeter.
Book standard units at least a few days out and ADA or trailer units earlier, since accessible inventory is smaller. Event weekends fill fast. If your date is inside a week, call rather than emailing; emergency porta potty rental covers same-day gaps but costs more than a planned order.
Placement on private property generally does not need a permit, but curb or right-of-way placement in Portland needs confirming with the city directly. See porta potty permit requirements before you finalize a curbside spot.
It depends on headcount, event length, and whether alcohol is served. Use how many porta potties do I need to run the numbers instead of guessing; construction crews should reference OSHA 1926.51(c) ratios instead.
Usually yes, but availability is tighter than for standard units. Confirm site access meets ADA Standards 405.2 for ramp slope if the unit sits above grade, and book the swap as early as possible through request a quote.
A porta potty is a single self-contained unit; a restroom trailer rental has multiple stalls, running water, and often climate control. Trailers cost more but suit events over 100 guests better than stacking standard units.
