How many portable toilets do I need?
OSHA 1926.51(c)(1) sets the baseline for construction: one toilet facility for 20 workers or fewer, then one toilet seat and one urinal per 40 workers up to 200, and one per 50 at 200 or more. An event in a park needs different math, it's based on expected attendance and duration. A standard porta potty rental holds 60 to 70 gallons and measures about 44 by 48 inches on the ground. Read how many porta potties do I need for the full calculator, or call us with your headcount and we'll spec it right. Weddings, concerts and festivals in Seattle each have different rules for density and access.
What's the difference between a standard unit and a deluxe one?
A standard porta potty rental is a no-frills vault toilet. It works. A deluxe flushable porta potty adds a flushing mechanism, a foot pump, a higher-capacity waste tank and better hand sanitation, and costs more. If your crew or guests use the unit heavily or you need it to feel less like a construction site, go deluxe. If it's a safety backup or overnight use, standard does the job. Both types rent by the day, week, weekend or month, and we service them weekly per ANSI/PSAI Z4.3 baseline intervals.
Does Seattle require a permit for a portable toilet in my yard or driveway?
A porta potty permit requirements page covers the rules in depth. In Seattle, placement in the public right-of-way, a sidewalk or parking strip, requires a Street Use permit from the Seattle Department of Transportation (SDOT) under Seattle Municipal Code Title 15. A portable toilet on your own property, driveway or fenced yard does not need an SDOT permit. If you're unsure whether your placement counts as the right-of-way, call us before we deliver. We've rented to homeowners from Mercer Island to Federal Way and know the boundary lines. Storage containers and roll-off dumpster rental in the right-of-way do require SDOT permits, and we can walk you through that process too.
What if I need a restroom for an event or construction job that lasts weeks?
A restroom trailer rental is the answer. Trailers come in 2-stall, 4-stall and 8-stall sizes with hot water, soap, mirrors and towel dispensers that feel like real bathrooms. They're heated, lit and can run for months on a monthly rental. A 2 stall restroom trailer fits on most job sites in Seattle; a 4 stall restroom trailer serves 20 to 30 people comfortably. Trailers need about 60 feet of straight clearance behind the truck to deliver. Pricing runs higher than portable units but the user experience is worth it for crews who spend all day on site or for weddings and festivals where you want guests comfortable.
What if I also need a dumpster or septic pumping?
Seattle Porta Pros handles roll-off dumpster rental alongside toilets. If you're demolishing or renovating, rent a dumpster and portable units together and save on separate delivery fees. Septic pumping service is a separate call, residential tanks pump every 3 to 5 years depending on household size and tank volume, but we service both. A grease trap pumping job at a restaurant or food truck runs on a different schedule: grease interceptors pump when fats, oils and solids hit 25 percent of the liquid depth. Handwashing station rental rounds out job sites where crews apply paints, coatings or herbicides; 29 CFR 1910.141(d)(2) requires soap and towels, not hand sanitiser alone.
How much does a standard porta potty cost per day, week or month?
Pricing varies by duration and rental length. Daily rates run $100 to $350 for a standard unit; weekly is $130 to $500; monthly is $125 to $325. A delivery fee of $50 to $150 applies for weekend rentals depending on location. Call for a quote on your dates.
Can I rent a portable toilet for just a weekend?
Yes. A weekend rate typically runs $125 to $400 for a standard unit, plus delivery. Weekend porta potty rental fits events, camping trips and short job stretches. Book at least a week ahead in Seattle if you can.
What's an ADA-accessible portable toilet and when do I need one?
An ADA accessible porta potty has a 36 inch minimum clear width per ADA Standards section 403.5.1, a 32 inch door opening, a 60 inch turning circle, and meets 5 percent clustering rules. You need one if your event or job site expects visitors or employees with mobility limits. Seattle Parks and most public festivals require at least one accessible unit per cluster of 20 standard units.
How often do portable toilets get serviced?
We service rented units weekly. That's the baseline interval per ANSI/PSAI Z4.3 for up to 10 users over a 40 hour week. Heavy use or multiple units may need twice-weekly service. Ask about custom schedules.
