How many units do I actually need?
Start with worker or guest count, then match it against the ratio in OSHA 1926.51(c). For construction crews, that's 1 toilet for 20 workers or fewer, climbing to 1 toilet seat and 1 urinal per 40 workers once you pass 20, then 1 per 50 at 200-plus. Events run differently since people cluster around programming, not workstations. A wedding at 150 guests needs more capacity than a job site with the same headcount spread across eight hours. Chandler Porta Pros walks through both scenarios on the how many porta potties do I need page, but the checklist habit is this: count heads first, pick standard units or a restroom trailer second. If your crew is doing paint, coatings, or pesticide work, washing facilities fall under OSHA 1926.51(f)(1), which is a separate requirement from toilet counts. Farms and hand-labor operations follow OSHA 1928.110 instead, with one facility per 20 workers inside a quarter mile walk, which matters for farm and agricultural restrooms around the Chandler area.
What size clearance does the delivery truck need?
A roll-off or restroom trailer delivery needs about 60 feet of straight clearance behind the truck, so walk your driveway or lot before the delivery window opens. A standard portable unit is a smaller footprint, about 44 by 48 inches on the ground and 92 inches tall, which fits most side yards and construction pads without a second thought. Tight urban lots near downtown Chandler are where clearance actually bites. If you're renting a roll-off dumpster alongside your restrooms for a renovation job, check the dumpster sizes and dimensions page before you commit to a delivery date, because a blocked alley means a rescheduled truck and a delayed start. For events at parks or open lots, sketch out placement ahead of time using the porta potty placement guide, especially if you're also bringing in a light tower or temporary power pole that needs its own access lane.
Do I need an ADA accessible unit?
Yes, if you're clustering portable toilets for an event or job site, ADA Standards section 213.2 requires at least 5 percent of the units be accessible, and never fewer than one. An ADA accessible unit needs a 60 inch turning circle inside per ADA 304.3.1, a 32 inch clear door opening under ADA 404.2.3, and a 36 inch clear approach route per ADA 403.5.1. Ground underneath has to be stable and slip resistant per ADA 302.1, which rules out loose gravel or soft turf as a pad. Operable parts like door latches can't require tight grasping or more than 5 pounds of force under ADA 309.4. Chandler venues hosting public events, from festivals to golf tournaments, should treat this as a checklist line item, not an afterthought. Full detail lives on the ADA restroom requirements page.
When should I schedule service and pickup?
Book service on a weekly cadence at minimum. ANSI/PSAI Z4.3 sets one visit per week as the baseline for up to 10 users across a 40 hour week, so a busy event or high-traffic job site needs more frequent stops, not fewer. Multi-week construction projects in Chandler typically run monthly rentals with service built into the contract, while a weekend wedding or block party usually books a single delivery and a single pickup. Check the how often are porta potties cleaned page for what a standard visit covers. If you're running a septic pumping job at the same property, note that a residential tank is typically pumped every 3 to 5 years depending on tank size and household size, which is a different clock than your rental units entirely. Handwashing stations need soap and towels or a hand dryer under 29 CFR 1910.141(d)(2); hand sanitizer alone does not satisfy that rule, so budget for a real handwashing station rental if you expect food service or a mobile crew.
| item | day | week | month |

How far in advance should I book?
Book construction rentals as soon as you have a start date, since monthly units get committed fast during busy building seasons. Events should book 3 to 4 weeks out, and holiday weekends need more lead time. Chandler Porta Pros can often accommodate short notice, but emergency porta potty rental requests cost more and have fewer size options.
What's the difference between a standard unit and a deluxe unit?
A standard unit has a 60 to 70 gallon holding tank, a hand sanitizer dispenser, and basic ventilation. A deluxe flushable unit adds a flush mechanism, a sink, and better interior finish. Weddings and corporate events usually choose deluxe; job sites usually choose standard.
Can I place a unit in the street or right of way?
That needs confirming with the City of Chandler before you commit to a spot. Placement rules for right-of-way vary by location and use case, so check with the city directly rather than guessing, and see the porta potty permit requirements page for what to ask about.
Do I need a permit for a dumpster too?
Possibly, depending on where it sits. If the dumpster goes on a street or public easement, check with the city first. The dumpster permit requirements page covers what to confirm before delivery day.
What can't go in my rented dumpster?
Certain hazardous and prohibited materials are off-limits regardless of dumpster size. Check the what cannot go in a dumpster page before loading, since violations can mean extra fees or a rejected pickup.
