How many units do you need?
Start with headcount, not guesswork. OSHA 1926.51(c) sets the baseline for construction crews: one toilet for 20 workers or fewer, then one toilet seat and one urinal per 40 workers once you pass that line, dropping to one per 50 once you hit 200 workers. Events run differently, since people cycle through faster and drink more. ANSI/PSAI Z4.3 uses one unit per 10 users across a 40 hour week as its baseline service interval, which is a decent starting ratio for a single-day event too. If you're not sure which category you fall into, How Many Porta Potties Do I Need in Spokane, WA walks through both. Weddings, fun runs and fairs each pull different numbers, and our wedding restroom rental and marathon and race restrooms pages break those down by guest count and course length.
What size and type of unit fits the job?
A standard unit holds 60 to 70 gallons and sits about 44 by 48 inches on the ground, standing roughly 92 inches tall. That's the workhorse for job sites and most outdoor events, and you can see current rates on our standard porta potty rental page. If the client expects something nicer, a deluxe flushable porta potty adds a flush mechanism and a sink. Federal accessibility rules require at least 5 percent of a cluster to be accessible, and never fewer than one, per ADA Standards 213.2, so any event over roughly 20 units needs an ADA accessible porta potty on-site. For larger builds, a 4 stall restroom trailer or 8 stall restroom trailer beats lining up a dozen single units, and it looks a lot better for weddings or festivals. Check the portable toilet rental and portable restroom rental pages if you're still comparing formats before you call.
Where should the units go?
Placement decides whether delivery goes smoothly or gets rescheduled. Units need a flat, stable surface, since ADA Standards 302.1 requires ground that's firm and slip resistant, and that rule matters even if you're not ordering an ADA unit, because tipped toilets are a real problem on gravel or soft turf. Leave a clear path at least 36 inches wide per ADA Standards 403.5.1 so anyone using a wheelchair or walker can actually reach the door, and make sure the door opening clears 32 inches per ADA Standards 404.2.3. If you're renting a roll-off dumpster alongside your restrooms, the truck needs about 60 feet of straight clearance behind it to set the container down, so map that route before delivery day. Our porta potty placement guide covers slope, access and distance from structures in more depth, and porta potty permit requirements is worth a read if the unit will sit anywhere near a public sidewalk or street in Spokane. Placement in the right of way needs confirming with the city directly, since that call varies by block and by permit.
Do you need anything besides toilets?
Most job sites need more than toilets alone. OSHA 1926.51(a)(1) requires an adequate supply of potable water at every workplace, and 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device wherever handwashing is provided, since hand sanitizer alone doesn't satisfy that rule. A handwashing station rental or portable sink rental solves both at once. If your crew is applying paint, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) kicks in specifically for that work and requires washing facilities beyond the general minimum. Construction sites juggling debris, fencing and temporary power should look at construction site services as a starting point, and if you're renting a temporary fence rental or a light tower rental for the same job, bundling delivery saves a trip. Ag operations have their own standard: OSHA 1928.110 requires field sanitation within a quarter mile walk of hand-labor employees, one facility per 20 workers, which our farm and agricultural restrooms page covers in detail.

How far in advance should I book?
Book as soon as you have a date and headcount, especially for weekend events, since trailers and ADA units book up faster than standard toilets. Spokane crews building a schedule around a construction dumpster rental or temporary fence rental should request all services together through Request a Quote in Spokane, WA.
Do I need an ADA unit for a small backyard party?
Not usually. ADA Standards 213.2 applies to clustered units at public or commercial events, not private residential gatherings. If you're hosting anything open to the public in Spokane, plan on at least one accessible unit.
What if I only need a toilet for a weekend?
Weekend rentals are common for parties and small jobs, and pricing differs from a full week or month. See Porta Potty Rental Per Day in Spokane, WA for how that compares.
Can I rent a dumpster and porta potty together?
Yes, and it's common on renovation and construction jobs. Check Roll-Off Dumpster Rental in Spokane, WA or 10 Yard Dumpster Rental in Spokane, WA alongside your restroom order to schedule one delivery window.
Does Spokane Porta Pros serve towns outside Spokane?
Yes. Spokane Porta Pros delivers to Town and Country, 4.6 miles north, Cheney, 17.4 miles southwest, and other nearby towns listed on Service Areas in Spokane, WA.
