Frequently Asked Questions in Berkeley, CA

OSHA requires 1 toilet facility for every 20 workers or fewer on construction sites, then 1 toilet seat and 1 urinal per 40 workers from 20 up to 200 workers, and 1 toilet seat and 1 urinal per 50 workers at 200 or more under OSHA 1926.51(c)(1). The count depends on how long people stay on site and whether you have both men and women. An event in Berkeley with 60 guests needs fewer than a 10-hour construction shift with the same count. Call us with your worker count or guest list and we'll size it correctly. See our guide to how many porta potties you need for more detail on events, construction and agricultural work.

Standard units are the baseline: a toilet seat, a urinal and a holding tank. A deluxe flushable porta potty adds a flush mechanism, hand soap and a sink, which makes it feel more like a real bathroom. Deluxe rents higher but matters most when guests will use the toilet for hours, not minutes. Construction sites usually choose standard. Weddings, festivals and outdoor office work often go deluxe because people care about comfort and cleanliness. Both get serviced weekly under the baseline interval. Compare standard porta potty rental and deluxe to see which fits your budget and use case.

Yes, if you have employees or guests with disabilities who need to use the restroom. An ADA accessible porta potty has a 36 inch minimum clear width of the accessible route under ADA Standards section 403.5.1, and a 32 inch minimum door opening width under ADA Standards section 404.2.3. If you cluster multiple units, at least one must be accessible under ADA Standards section 213.2. Berkeley employers and event hosts are responsible for meeting access rules. We can place an ADA unit alongside standard ones. Contact us to discuss your setup.

Weekly is the baseline interval for up to 10 users over a 40 hour week under ANSI/PSAI Z4.3. Busy sites and events may need twice-weekly or daily service. We pump the tank, replace toilet paper, clean the seat and urinal, and restock soap. The holding tank on a standard unit is 60 to 70 gallons, so sites with heavy use fill faster. Tell us your user count and we'll set up the right service schedule. How often are porta potties cleaned covers the details.

Restroom trailer rental works for weddings, festivals, concerts and film sets where you need multiple stalls with running water, flushing toilets and mirrors. A 2 stall trailer fits 20 to 30 people per event hour. A 4 stall or 8 stall restroom trailer handles larger crowds. Trailers need about 60 feet of straight clearance behind the delivery truck, level ground and access to a water hookup or portable water tank. See restroom trailer rental cost for pricing by stall count and duration.

Yes. A roll-off dumpster rental takes construction debris, yard trimmings, broken drywall and general demolition. Different sizes fit different jobs: a 10 yard dumpster works for small renovations, a 20 yard for medium jobs, and a 30 yard dumpster or larger for major cleanups. We deliver it, you load it, and we haul it away. See dumpster rental cost and our guide to what cannot go in a dumpster before you book.
