Deluxe Restroom Trailer Rentals in South San Francisco, California

Plan on a spot about the length of the trailer plus a few feet at each door for the steps or ramp. A 2-Station fits most single-car driveways. On sloped streets in Westborough or Paradise Valley, we level the trailer with jacks and blocking, so a gentle grade is fine. Very steep driveways or low wires may call for a curb placement instead, so send us photos first.

The trailer on your own driveway does not need its own permit. The event may: South San Francisco asks for a private event permit when 75 or more people attend a party at a home or rented hall. Townhome and condo HOAs sometimes limit street parking or trailers, so check your rules and tell us early. A curb placement on a public street can need city sign-off.

Probably not for a full evening. A 2-Station is comfortable for about 50 to 75 guests over a few hours. For 150 guests and five or six hours with an open bar, a 3-Station or a 5-Station keeps the line short. Tell us your guest count, the hours and whether there is a bar, and we will size it.

Yes. We offer attendants for long receptions, formal dinners and festivals. The attendant keeps the sinks and floors dry, restocks paper and soap, checks every room through the night and takes care of small issues fast. Shorter parties usually do fine with our full stock and setup at delivery.

Yes, and guests notice right away. A porta potty is a plastic box with a holding tank and no sink. Our trailers have separate women’s and men’s rooms, flushing china toilets, sinks with running water, mirrors, lights, heat and air conditioning. They look and feel like a nice indoor bathroom.

Our units are staged in the Bay Area and run up and down the Peninsula every week. For weddings and parties, we usually deliver the day before and pick up the day after. For campus events east of 101, we deliver early in the morning or the evening before to avoid airport-area traffic. Film crews get delivery before call time.

We set the trailer once and service it on a schedule, usually weekly. That covers pumping the waste tank, refilling fresh water, cleaning and restocking. Lab buildouts and office remodels often keep a unit for months as the clean restroom for owners, architects and visiting clients.

As early as you can. June graduation weekends and September Saturdays book first in South City, partly because Concert in the Park and Festa Italiana land in September too. Couples who call in winter or early spring get the unit and size they want. Last-minute requests still get a call back, and we will check what is open.

No. Every trailer carries its own fresh water tank and a sealed waste tank, so it works on a bare lot or a lawn. A hose connection can help on a multi-day event, but it is not required. The waste never drains on site. Our service truck pumps it.

For the 2-Station, 3-Station and 5-Station, yes, if the outlet is on its own 20 amp, 120 volt circuit. The 9-Station and the ADA + 2 need two circuits. If your outlets are shared with other loads or too far away, we bring a quiet generator.

Afternoon west winds are common in South City, especially near Oyster Point and the east side. The trailer itself is heavy and stable once the jacks are down. We tie down canopies and signs near the entry and face the doors away from the wind when the site allows.

Start with the busiest hour, not the total guest list. A backyard reception in Avalon Park with 120 guests, a buffet and an open bar will see most people use the restroom between dinner and the first dance. A 2-Station handles about 50 to 75 guests over a few hours. A 3-Station, with two women’s rooms and one men’s room, is the better choice from about 100 to 175 guests. Above that, or past five hours, the 5-Station is the safe pick, since it carries three women’s stalls, a men’s stall and a urinal. Kids and grandparents add more trips than you expect, so round up when in doubt.

Plan at least one accessible room if any guest uses a wheelchair, a walker or a cane. The ADA + 2 covers that with a ramp and still gives you a women’s room and a men’s room. Federal accessibility guidance is a good reference for public events. Give us your count, your hours, and whether the bar is open all night, and we will size the unit with you on the phone.

Hillside streets on the west side of South City are the trickiest drops we make here. The questions we ask are simple. How steep is the driveway? Is there a sharp turn at the bottom of the street? Are there low wires, trees or a parked RV in the way? A phone photo of the street from the curb, plus one of the driveway from the sidewalk, answers most of them. A gentle grade is fine because our stabilizer jacks and blocking set the trailer level. A steep grade toward the street usually means a smaller unit or a curb placement.

Curb placements on a public street may need city sign-off, so leave time for that. Keep the path from the yard to the steps clear and lit, and mark any step-down at the curb. Run power from a garage outlet on its own circuit, or let us bring a generator. Give neighbors a heads-up about the trailer and the delivery truck. Most of them are glad the party is not using the house bathroom.

Facilities teams on the east side juggle security, loading docks and shift changes, so the restroom plan needs to fit those rules. Ask which lot or lawn the event will use, where the fire lanes run, and whether the parking structure has a height limit. Ask who signs off on delivery windows and whether the trucks need an escort. Find out where the nearest outlet is and how many circuits it can spare. The answers decide the unit size, the placement and whether we bring a generator.

Next, confirm the guest count by hour, not just the total. A picnic with families and a band peaks at lunch, while a launch party peaks right after the speeches. If the event spills onto a public street or needs city coordination, the special event permit asks for a site plan filed at least 60 days ahead. Ask for an attendant on any event longer than four hours, and plan an accessible unit next to the main trailer.

South San Francisco sits where ocean air pushes through the hills toward the bay, so afternoon west winds of 10 to 25 miles per hour are normal from late spring through summer. Fog rolls in by evening. For a mobile restroom trailer that means three things. Tie down canopies, banners and anything light near the doors. Face the doors away from the wind when the site allows. Turn the heat on before guests arrive so the rooms are warm when the fog comes in.

Winter is the wet season, and the storms of December 2022 and January 2023 showed how fast lawns turn to mud. Between November and March we set trailers on pavement, gravel or plywood rather than soft grass. We also add mats at the steps and keep an eye on gutters and low spots near the drop. Checking the forecast a few days out lets us adjust the plan before the truck rolls.

National Weather Service forecast for South San Francisco

A broken water main can shut the restrooms in a restaurant on Grand Avenue in a single morning. A sewer backup can do the same to an office near Gateway. Without working restrooms, most businesses have to close. A temporary bathroom trailer in the back lot or at the curb keeps the doors open while the plumber works. Our units carry their own water and waste tanks, so they do not depend on the building’s broken pipes. Call us with the address and how many people use the restrooms each day, and we will size the unit.

Homeowners face the same problem on a smaller scale. A remodel that pulls the only toilet in a Buri house can last weeks. A 2-Station in the driveway, serviced weekly, keeps the family at home instead of in a hotel. Tell us how long the job should run. We can extend the rental week by week if the work runs long.
