Frequently Asked Questions in South San Francisco, CA

OSHA 1926.51(c)(1) sets the minimum: one toilet facility for 20 workers or fewer, then one toilet seat and one urinal per 40 workers from 20 up to 200, and one toilet seat and one urinal per 50 workers at 200 or more. A 10-person crew needs one unit. A 60-person job needs two toilets and two urinals, which often means two or three portable units depending on layout. Check your site plan, some supervisors add an extra unit for convenience even when code allows fewer. Call South San Francisco Porta Pros to discuss your headcount and we'll size it right. See our OSHA portable toilet requirements guide for the full breakdown.

A standard portable toilet holds 60 to 70 gallons and measures about 44 by 48 inches on the ground, standing 92 inches tall. It has a gravity flush, a toilet seat, a urinal and hand soap. A deluxe flushable unit adds an electric flush valve, running water in the sink, and an inside tank flush for better sanitation. Deluxe models cost more per day or week. Both fit standard delivery trucks. For standard porta potty rental work, standard units work fine. For offices, events or sites where users prefer flush toilets, deluxe pays off. South San Francisco Porta Pros can deliver either within 24 hours.

One service visit per week for up to 10 users over a 40-hour week is the baseline interval under ANSI/PSAI Z4.3. Heavy use sites, 20 or 30 workers, need two or three visits. We pump during your work hours or after hours. A standard unit holds 60 to 70 gallons; once that tank fills, it needs emptying. South San Francisco Porta Pros schedules pumping on your calendar. See how often porta potties are cleaned for more detail on frequency by site type.

Yes. We rent roll-off dumpsters in 10, 20, 30 and 40-yard sizes. A 10-yard fits residential cleanouts and small renovations. A 20-yard handles kitchen remodels and light construction debris. A 30-yard suits larger projects. A 40-yard takes major demolition and earth moving. Pricing runs by the week and month. See our roll-off dumpster rental page and dumpster weight limits before you order, some materials cost extra or cannot go in. South San Francisco Porta Pros delivers and picks up; a roll-off needs about 60 feet of straight clearance behind the truck.

Restroom trailers have stalls, running water, flushing toilets and sinks inside a wheeled unit. They're cleaner and faster than portable toilets for large events. South San Francisco Porta Pros rents 2-stall, 4-stall and 8-stall models. See our restroom trailer rental page for pricing and 2-stall, 4-stall and 8-stall options. Trailers cost more than standard units but handle 50 to 200 people per day depending on stall count. Book early for summer events; they fill fast.

See our handwashing station rental page for pricing and handwashing requirements.

ADA Standards section 213.2 requires that where single-user units are clustered, at least 5 percent, and never fewer than one, be accessible.
