How many units do I actually need?
Start with headcount, then check OSHA 1926.51(c). It sets 1 toilet for 20 workers or fewer on a construction crew, then 1 toilet and 1 urinal per 40 workers once you pass 20. For events, most planners lean on our how many porta potties do I need guide because foot traffic and beer sales change the math fast. A backyard remodel in Tempe usually gets by with one standard porta potty rental, while a weekend festival needs a cluster plus at least one accessible unit. ADA Standards section 213.2 requires that where single-user units are grouped, at least 5 percent be accessible, and never fewer than one. If you're building a crew schedule around a construction job, our construction site services page walks through staging alongside dumpsters and fencing. Don't guess on quantity. Under-ordering means lines, and lines mean complaints that land on the general contractor, not the renter.
What size and type of unit fits my job site?
A standard unit runs about 44 by 48 inches on the ground and stands roughly 92 inches tall, so measure your placement spot before delivery day. Tempe job sites near tight alleys or fenced lots should confirm clearance, especially if a roll-off dumpster rental is sharing the same pad. If you want a nicer option for a wedding or backyard party, look at the deluxe flushable porta potty or step up to a 2 stall restroom trailer for guest comfort. Every accessible unit needs a 60 inch turning circle inside per ADA Standards section 304.3.1, and the door opening has to clear 32 inches per section 404.2.3. If your crew includes a wheelchair user or you're required to provide access, order the ADA accessible porta potty up front rather than swapping units later. Ramps, if used, can't exceed a 1:12 slope under section 405.2.
Where should the unit go on my property?
Surface stability matters more than most renters expect. ADA Standards section 302.1 calls for stable, firm, slip-resistant ground, which rules out soft dirt or loose gravel for any accessible unit. Our porta potty placement guide covers clearance from doors, windows, and property lines in more detail. If delivery involves a roll-off too, remember a roll-off truck needs about 60 feet of straight clearance behind it to drop the box safely, so plan driveway access accordingly. Placement in the public right of way in Tempe needs confirming with the city before delivery, since we can't state a blanket rule here. If you're near Guadalupe, about 3.5 miles southwest of Tempe, or coordinating a multi-site job, check our service areas page for coverage. For events with heavy foot traffic, keep operable parts like door latches easy to use with one hand and under 5 pounds of force, per ADA Standards section 309.4, so units stay functional for every guest.
When should I schedule delivery and service?
Book delivery at least a few days ahead for standard weekend rentals, and further out for anything overlapping a holiday or a big Tempe event. ANSI/PSAI Z4.3 sets a baseline of one service visit per week for up to 10 users across a 40 hour week, which works for a small job site but not a three-day festival. Multi-day events need daily or twice-daily service instead. Check our how often are porta potties cleaned page if you're planning service intervals for a long build. For anything urgent, same-day options exist through emergency porta potty rental. If your event includes food service, pair your restroom order with a handwashing station rental, since 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at wash stations, not sanitizer alone. Weddings and races both benefit from locking in event restroom rental or marathon and race restrooms scheduling early, before weekend slots fill.

Do I need a permit for a porta potty in Tempe?
Maybe, depending on where you place it. Confirm placement rules with the city directly since specifics vary by property and zoning. Our porta potty permit requirements page outlines what to ask about before you book delivery.
How far in advance should I book for an event?
Book two to four weeks out for weekend events, longer for large festivals or races. Standard units book faster than restroom trailer rental options, which have limited inventory during Tempe's busy event season.
Can I get an ADA unit added to an existing order?
Yes, but add it early. ADA Standards section 213.2 requires at least one accessible unit in any cluster, and swapping a standard unit for an accessible one after delivery costs more than ordering it upfront.
What happens if a unit runs low on service between visits?
Call for an extra visit. High-traffic events strain the 60 to 70 gallon tank faster than a quiet job site, so flag expected heavy use when you book to avoid a mid-event overflow.
Do I need handwashing if my crew uses paint or solvents?
Yes. OSHA 1926.51(f)(1) requires washing facilities where workers apply paints, coatings, herbicides or insecticides. A portable sink rental or handwashing station covers that requirement on site.
