Frequently asked questions
How many portable toilets do I need?
The math depends on how many people use them and for how long. OSHA 1926.51(c)(1) requires 1 toilet facility for 20 workers or fewer on a construction site; from 20 to 40 workers you need 1 toilet seat and 1 urinal; at 200 or more workers the ratio is 1 toilet seat and 1 urinal per 50 workers. For events, estimate 1 unit per 75 to 100 guests for a 4-hour gathering. A standard porta potty holds 60 to 70 gallons and needs weekly service under normal use. Encinitas Porta Pros will size your order based on your crew count and event length. Call with those numbers and we'll quote what works.
How often are porta potties cleaned?
Service frequency matters more than most renters realize. One service visit per week for up to 10 users over a 40-hour week is the baseline interval under ANSI/PSAI Z4.3, the portable sanitation service standard. Busier sites need twice-weekly or even daily service. Encinitas Porta Pros schedules service on a weekly cycle by default, but can adjust for your actual demand. Weekend service and emergency same-day pumping are available. Tell us your foot traffic and we'll set a schedule that keeps the unit usable.
What about ADA accessibility?
Accessible units exist and must meet ADA Standards section 213.2: at least 5 percent of clustered single-user units must be accessible, and never fewer than one. An ADA accessible porta potty has a wider door, interior grab bars, and enough space for a wheelchair. A standard unit is about 44 by 48 inches on the ground; an accessible unit occupies more space and costs more to rent. Encinitas Porta Pros stocks ADA compliant units for construction sites and events in Encinitas that require them. Ask whether your job qualifies and whether placement in the public right of way needs confirming with the city.
What can't go in a roll-off dumpster?
Many items are forbidden: hazardous waste, paint, batteries, electronics, tires, appliances and liquids of any kind. Asbestos, medical waste and radioactive material are illegal. Some materials require separate disposal or special containers. Check your demolition plan before loading anything questionable. Encinitas Porta Pros will tell you on the phone what the dumpster weight limits allow and what stays out. A 20-yard dumpster holds roughly 6 tons; overloading costs more and delays pickup.
How much does a restroom trailer cost compared to porta potties?
Trailers cost more upfront but serve larger events and longer rentals better. A restroom trailer is a full bathroom on wheels with running water, flushing toilets and sinks. A standard porta potty is a tank and a seat. Trailers run 150 to 1650 dollars weekly depending on size and amenities; standard units run 130 to 500 dollars weekly. Delivery adds 50 to 150 dollars per week. For a 3-day festival in Encinitas, rent a trailer. For a 2-week construction job, porta potties make sense. Compare options by event size and duration.
