At least one accessible unit is required whenever portable toilets are clustered on a jobsite or event site, per ADA Standards section 213.2, and that ratio holds even for small setups. Portland Porta Pros sets accessible units on every order over a handful of toilets, no separate request needed.
An ADA unit is bigger, and the numbers matter more than they look. Under ADA Standards section 304.3.1, the interior needs a 60 inch turning circle so a wheelchair can rotate without backing out the door. The door itself has to open at least 32 inches clear, per ADA Standards section 404.2.3, wider than the swing on a standard porta potty rental. Grab bars sit at a fixed reach range, and per ADA Standards section 308.2.1 controls can't sit higher than 48 inches or lower than 15 inches from the floor. Door hardware also has to work with a closed fist, not a pinch or twist, under ADA Standards section 309.4. Portland Porta Pros stocks these as a distinct line, separate from the deluxe flushable porta potty upgrade, because the compliance specs are fixed regardless of finish. You can browse the unit itself on the ADA accessible porta potty page, or start from the portable toilet rental hub if you're still deciding what fits the site.
One accessible unit per cluster is the floor, never zero, per ADA Standards section 213.2. That's a minimum, not a formula for total headcount. OSHA 1926.51(c) still sets the base ratio for construction crews: one toilet for 20 workers or fewer, then one seat and one urinal per 40 workers once you're above that, and per 50 once a site hits 200 workers. So a 60-person Portland framing crew needs toilets under the OSHA ratio, and at least one of whatever cluster you place has to meet the accessible spec. Event organizers run the same math differently. A wedding at a Portland venue with 150 guests works off headcount and hours, not labor law, and our how many porta potties do i need guide walks through that split. For general OSHA planning across a whole site, the OSHA portable toilet requirements page covers the full ratio table.
Path and ground matter as much as the unit. ADA Standards section 302.1 requires the ground under and around the unit be stable, firm and slip resistant, which rules out loose gravel or soft turf without a mat underneath. The route to the door needs a minimum 36 inch clear width, per ADA Standards section 403.5.1, and if there's any grade change getting there, a ramp can't exceed a 1:12 slope under ADA Standards section 405.2. That's a serious constraint on a sloped Portland lot or a downtown build site with limited flat ground. We check placement before delivery, since a Portland jobsite 8.9 miles southwest in Raleigh Hills has different grading than a flat commercial lot near the river. Our porta potty placement guide covers surface and clearance in more depth, and the porta potty rental checklist is worth running before delivery day so nothing gets set on the wrong spot.
Yes, and for larger events it's often the cleaner path to compliance. A restroom trailer rental with a dedicated ADA stall covers the same turning circle and door width specs as a standalone unit, but inside a climate controlled trailer with running water. That matters for weddings and formal events where a standalone accessible unit feels out of place. Our 2 stall restroom trailer and 4 stall restroom trailer options both include an ADA-compliant stall as standard, and the larger 8 stall restroom trailer scales that up for festivals or multi-day builds. Handwashing has to hold up too: 29 CFR 1910.141(d)(2) requires soap and a towel or air dryer at any washing station, not just sanitizer, and our handwashing station rental units are built to that standard. If you're planning a Portland event and unsure which format fits, the event restroom rental and wedding restroom rental pages break down trailer versus standalone by guest count.
An ADA unit typically runs $230 a day or $185 a week in Portland, similar to a standard unit but priced slightly higher for the larger footprint. Multi-week jobsites usually save by locking in the weekly rate up front. Full pricing detail sits on the porta potty rental cost page.
Placement in the public right of way needs confirming with the city before delivery. If your unit sits fully on private property, that's usually simpler, but check the porta potty permit requirements page and confirm with Portland before delivery day, especially for sidewalk or street-adjacent placement.
Often yes, for a guest count under the threshold where a second cluster becomes required. ADA Standards section 213.2 sets the floor at one unit whenever toilets are clustered, not a headcount trigger by itself. Our how many porta potties do i need guide runs the math for your specific guest count.
A standard unit runs about 44 by 48 inches on the ground and 92 inches tall, per our own measured specs. ADA units are built larger inside to fit the 60 inch turning circle required under ADA Standards section 304.3.1, with a wider door opening too.
