How many portable toilets do I need?
Compliance depends on your worker count. Under OSHA 1926.51(c), a construction site with 20 workers or fewer needs 1 toilet facility. Sites with 40 workers need at least 1 toilet seat and 1 urinal. At 200 workers, you're looking at 1 toilet seat and 1 urinal per 50 workers. Learn how to calculate your exact count. Event rules differ: a wedding, festival, or corporate gathering in Rialto has different math based on crowd size and duration. The baseline is one standard porta potty per 50 to 100 people over an 8-hour event, but that shifts with temperature, alcohol service, and whether restrooms are indoors nearby.
What does a standard unit include?
A standard unit holds 60 to 70 gallons and measures roughly 44 by 48 inches on the ground, standing about 92 inches tall. It includes a toilet seat, urinal, and waste tank. A standard rental comes with weekly service, that's waste removal, deodorizer, and restocking of toilet paper and hand sanitizer. For worksites where employees apply paints, herbicides or other harmful contaminants, OSHA 1926.51(f)(1) requires washing facilities with soap and towels; handwashing stations meet that need and include hot and cold water. Storage containers, dumpsters, and temporary fencing round out what we offer Rialto contractors and event planners.
How often is a unit serviced?
Once per week is the baseline for up to 10 users over a 40-hour workweek, per industry standard ANSI/PSAI Z4.3. High-traffic sites, construction with 40+ workers, outdoor festivals, or film sets, need twice-weekly or daily service. Rialto Porta Pros can adjust the schedule to your traffic and weather. Summer heat and large crowds drive demand up. Read our cleaning frequency guide for specifics. Weekend and emergency calls cost more; call for same-day pricing.
What's the difference between standard and deluxe?
Deluxe models include a foot-flush or hand-crank flush, running water, a sink, and upgraded interiors. They cost more than standard units but feel like a real restroom. Standard units are chemical toilets without flush or running water, they're lighter, cheaper, and better for remote or rough terrain. For Rialto construction sites and farm work, standard is industry norm. Deluxe works for weddings, corporate events, and upscale outdoor venues where guests expect comfort. Compare both in our cost guide.
Can I place a portable toilet in the street or my yard?
Placement in the public right of way needs confirming with the City of Rialto. Call your local permitting office to verify current rules. Private property, your yard, driveway, or parking lot, is usually fine if the ground is level and the unit has clear access. A roll-off dumpster delivery needs about 60 feet of straight clearance behind the truck. Check our placement guide for setback, level ground, and utility line safety. Rialto Porta Pros will advise on site conditions once you describe the space.
Do you service nearby towns?

How much does a porta potty cost per day?
Daily rates for a standard unit run $100 to $350 per day, depending on delivery distance and service frequency. See full pricing for standard, deluxe, and ADA models. Weekend rates typically run $125 to $400 for a standard unit.
Do you rent ADA accessible units?
Yes. ADA accessible portable toilets meet ADA Standards. Where units are clustered, at least 5 percent must be accessible, never fewer than one (ADA Standards section 213.2). They feature a 32-inch clear door opening (ADA Standards section 404.2.3), a 60-inch turning circle (ADA Standards section 304.3.1), and firm, slip-resistant flooring (ADA Standards section 302.1).
Can I rent a septic pumping service?
We pump septic tanks and grease traps. A residential tank is typically pumped every 3 to 5 years, depending on tank size and household size. Septic pumping costs and emergency service are available. Call Rialto Porta Pros for an estimate.
What can't go in a dumpster?
Hazardous waste, batteries, tires, and appliances are banned from most roll-off rentals. Paint, solvents, and asbestos require special handling. Read our full guide on restricted materials. Ask before you load.
How do I rent a restroom trailer?
Restroom trailers come in 2, 4, and 8-stall sizes. Trailers include running water, flushing toilets, sinks, and climate control, ideal for extended events and large crews in Rialto. Call for availability and pricing.
