How many portable toilets you need in San Mateo
Jobsite counts follow OSHA 29 CFR 1926.51(c); event counts follow the ratios most health departments and event permits expect. Use this as a starting point, then tell us your exact San Mateo crew or guest count and we size the order to code.
| People on site | Jobsite (OSHA, full week) | Public event (peak crowd) | Hand-wash stations |
|---|---|---|---|
| Up to 20 | 1 toilet | 1-2 toilets | 1 station |
| 20 to 50 | 2 toilets | 2-3 toilets | 1 station |
| 50 to 100 | 2-3 toilets | 3-4 toilets | 1-2 stations |
| 100 to 250 | 3-5 toilets | 5-7 toilets | 2 stations |
| 250 to 500 | 5-8 toilets | 8-12 toilets | 3 stations |
| 500 to 1,000 | Ask for a site plan | 13-20 toilets | 4-5 stations |
OSHA sets the jobsite floor: 1 toilet for up to 20 workers, then 1 toilet and 1 urinal per 40 up to 200, and 1 per 50 above that, with a unit within about a 10-minute walk. Event ratios assume a multi-hour crowd with food and drink; add units for alcohol, all-day duration, or long lines. At least 5 percent of event units (minimum one) must be ADA accessible.

Which portable toilet do you need in San Mateo?
Two questions size every order: how many people, and for how long. Here is how the five unit types map to the most common San Mateo jobs.
Construction & jobsites
Standard units are the jobsite workhorse in San Mateo. OSHA 1926.51(c) sets the minimum at 1 toilet for up to 20 workers, then 1 toilet plus 1 urinal per 40, and a unit has to be within about a 10-minute walk. On San Mateo sites, from a driveway remodel on a narrow residential street to a commercial job near the bay, we confirm a level spot and truck access before committing a date, keep units off gutters, drain inlets, and low ground in the flood-prone bayside neighborhoods during winter storms, and plan any street placement around the city's encroachment permit.
Weddings & upscale events
Deluxe flushing units or a luxury restroom trailer are the guest-facing picks. A flushing bowl and in-unit sink change how the whole event is remembered. For 100-plus guests, one trailer plus standard units for peak load usually beats two trailers on cost.
Public & permitted events
The 2010 ADA Standards require at least 5 percent of single-user units at a public event to be accessible, minimum one, each marked with the accessibility symbol. Every unit has ground-level entry, grab bars, and a full turning radius. Tell us your guest count and we build the right ratio in.
Food service & health-code sites
Wherever food is served or sold, health codes expect hand-washing. Pair a hand-wash station (one per roughly four toilets) with your units. Food-heavy events get one station per two toilets, and inspectors look for one near the vendors.
Delivery & placement in San Mateo
Same-day and next-day drop-offs
We deliver across San Mateo with same-day and next-day availability in most of the area when you book early. Weekend event units arrive clean before your event and leave after.
Level ground, clear approach
Units place best on firm, level ground with a clear path for the delivery truck. Restroom trailers need a reasonably level spot and access for delivery, and we confirm the site details with you before the truck rolls.
Permits handled
Private-property placement in San Mateo generally needs no permit. Public streets, sidewalks, and permitted public events may require one. Tell us where the unit goes and we will confirm what your address needs.
Service & sanitation
4 service visits per month, built in
Every 28-day monthly rental in San Mateo includes 4 service visits, roughly weekly. Each visit pumps the tank, sanitizes the interior, and restocks paper, soap, and sanitizer, so compliance never depends on a phone call.
Sized to OSHA 1926.51(c)
The federal construction sanitation rule sets 1 toilet for up to 20 workers, then 1 toilet and 1 urinal per 40, with a 10-minute access rule. We size San Mateo jobsites to that standard and add units when crews grow or usage climbs.
Hand-wash stations to code
One hand-wash station serves roughly four toilet units, the ratio most health departments expect. For food-service events we recommend one station per two toilets, one near the vendors and one near the units.
What renting a porta potty in San Mateo is actually like
San Mateo sits midway down the Peninsula between San Francisco and Silicon Valley, and we do not plan it like either end. Three local realities shape almost every San Mateo order: the San Mateo County Event Center, a 48-acre fair and expo campus that hosts the county fair every June and shows all year, a city event permit that has to be filed up to 90 days ahead, with a signed neighbor petition for a block party, and a bayside flood zone around Marina Lagoon where winter storms, not heat, decide where a unit can safely sit. Here is how each one changes what we recommend.
Mild Peninsula weather, winter storms, and the bayside flood zone
San Mateo's weather is mild most of the year, so heat rarely changes our service schedule here. What changes placement is water. The city says certain bayside neighborhoods have been mapped by FEMA as Special Flood Hazard Areas since 2001, with the latest flood map update effective October 11, 2024, and it created the North Shoreview Assessment District to fund the work to take those areas out of the flood zone. Voters approved a Community Flood and Storm Protection Fee in 2023 to maintain the city's aging storm drain system, and during big storms the city holds Marina Lagoon at lower levels and may staff it around the clock.
For a portable toilet, that means winter placement near the bay, the lagoon, or a creek takes more care. From November through March we keep units off low spots, gutters, storm drain inlets, and lagoon-edge lawns, set them on pavement or firm, level ground, and anchor them where storm winds come off the bay. When the city warns residents near a creek, lagoon, or hillside to shore up their property ahead of a storm, we check that a loaded service truck can still reach every unit and move any that sit in a spot likely to pond.
The San Mateo County Fair and a year-round Event Center calendar
The San Mateo County Event Center covers 48 acres, with seven buildings, more than 195,000 square feet of indoor exhibit space, and three large parking lots, and it has hosted events since the Little Flower Show in 1926. It is home to the San Mateo County Fair, which ran June 5 through June 14 in 2026 and is set for June 4 through June 13 in 2027, and it fills the rest of the year with consumer shows, trade events, and private gatherings. Vendors, exhibitors, and overflow parking areas around a large show often need extra restrooms and hand-wash stations beyond what the buildings provide.
For events at or around the Event Center, we plan units along the paths people actually walk between parking, food, and stages, add hand-wash stations wherever food is served, and service multi-day shows daily. Fair season in early June also books up delivery windows across the Peninsula, from graduations to neighborhood parties, so we recommend locking dates early. Tell us the show, the dates, the expected crowd, and where your booth or lot sits, and we build the unit count and delivery window around the event schedule.
Placement on city streets, block parties, and the San Mateo encroachment permit
Most San Mateo placements are private: a driveway remodel, a backyard party, a commercial lot, or a fenced jobsite. On private property with clear truck access, you generally do not need a city permit for a portable toilet. Because a unit on the street needs a permit here, we confirm a level spot on the driveway or lot, overhead clearance, and a route in before the truck rolls.
Street placements and events run on fixed city timelines. The City of San Mateo Public Works Department requires an encroachment permit for any work in the public right-of-way, submitted by email with insurance naming the city, a site plan or traffic control plan, a permit fee, and a security deposit. A public event on city property or a roadway, or a private event that affects one, from a festival or race to a farmers' market, needs a Special Community Events Permit filed at least 90 days ahead for a new event or 45 days for a repeat one. Closing a residential street for a block party takes a Residential Block Party Permit filed at least 20 business days ahead, with a petition signed by every affected resident. A unit can never block a sidewalk, curb ramp, driveway, or hydrant. Give us the address and whether the spot is private or public, and we confirm what the placement needs and coordinate before delivery. See the City of San Mateo encroachment permit requirements.

Porta potty rental in San Mateo, CA: FAQs
Common questions about portable toilet rental in San Mateo, California.
A standard portable toilet in San Mateo, CA starts at $345 for a weekend rental (up to 7 days) or $395 per month, with 4 service visits included in every 28-day rental. Upgrades: deluxe flushing units run $449/weekend, ADA-accessible units $449/weekend, luxury restroom trailers from $1610/weekend. Every San Mateo rate is all-inclusive: delivery, pickup, fuel, and environmental and local fees are built into the one price, so there are no surprise line items. Online orders are $0.39 higher than the phone price; either way, we deliver and service the unit ourselves. Enter your ZIP for your exact San Mateo rate.
OSHA's construction sanitation rule, 29 CFR 1926.51(c)(1), sets the floor: 1 toilet for 20 or fewer workers; 1 toilet seat and 1 urinal per 40 workers from 20 up to 200; and 1 toilet seat and 1 urinal per 50 workers above 200. OSHA also expects a worker to reach a toilet within about a 10-minute walk. On a San Mateo construction site we size to the OSHA table and the crew's real traffic rather than the mild weather, add a hand-wash station at the break area, and in winter keep units on firm, raised ground away from drainage paths near the bay and Marina Lagoon. Tell us the crew size and we will size the order to the standard.
Our standard San Mateo monthly rental includes 4 service visits over the 28-day period, roughly weekly. Each visit pumps the tank, sanitizes the interior, and restocks paper, soap, and hand sanitizer. San Mateo's mild weather means heat rarely forces extra visits, so frequency here follows use: a busy jobsite crew, a multi-day show at the Event Center, or a large party can fill a tank before the week is out, and on those we add visits or service daily. In winter we check units after storms, especially near the bay, Marina Lagoon, and creeks, and move any that sit where water collects. Service is built into the rate, so it never depends on anyone remembering to call.
For an event open to the public, yes. The 2010 ADA Standards for Accessible Design require that at least 5 percent of the single-user portable toilets in each cluster be accessible, with a minimum of one, and each accessible unit is marked with the International Symbol of Accessibility. (Units provided only for construction workers are exempt.) In practice a small San Mateo event needs at least one accessible unit; a larger one needs one per every 20 standard units. ADA units in San Mateo run $449 for a weekend. The accessible unit has ground-level entry, interior grab bars, and a full wheelchair turning radius, and it needs firm, level ground with a clear approach path. Tell us your guest count and we will build the right ratio in.
On private property with clear truck access, a driveway, a backyard, a commercial lot, or a fenced jobsite, you generally do not need a city permit for a portable toilet in San Mateo. If any part of the unit sits in a public street, on a sidewalk, or in a public easement, the City of San Mateo Public Works Department requires an encroachment permit, with insurance naming the city, a site plan or traffic control plan, a fee, and a security deposit. Events on city property or roadways need a Special Community Events Permit filed 90 days ahead for new events or 45 days for repeat events, and a block party needs a Block Party Permit 20 business days ahead. A unit can never block a sidewalk, curb ramp, driveway, or hydrant. Tell us the exact address and whether the spot is private or public, and we confirm what your placement needs and coordinate with the city before delivery.
A standard unit is the jobsite and everyday-event workhorse: enclosed, stocked, and cost-effective at $345/weekend. A deluxe flushing unit adds a foot-pump flushing bowl and an in-unit sink for guest-facing events like weddings and corporate functions at $449/weekend. A luxury restroom trailer is a climate-controlled, multi-stall unit with porcelain toilets, running-water sinks, and mirrors, indistinguishable from a fine-venue bathroom, from $1610/weekend. Pick by how guest-facing the site is and how long the rental runs.
Yes. We deliver and service portable toilets throughout San Mateo and the surrounding San Mateo metro area, with same-day and next-day drop-offs available in most of the area when you book early. Weekend event units are delivered clean before your event and picked up after. Enter your ZIP or call (866) 858-3867 and we will confirm the soonest available delivery for your address.
Yes. A freestanding hand-wash station pairs with any toilet unit and needs no power or water hookup: it has a foot-pump faucet, soap, and paper towels, stocked at delivery and every service visit. One station serves roughly four toilet units, the ratio most health departments expect. For food and drink events in San Mateo, plan a station near the vendors and one near the toilets to cover both inspection points.
Start with the city's timeline. If your event uses city property or a roadway, or will affect one, San Mateo requires a Special Community Events Permit filed at least 90 days ahead for a new event and 45 days ahead for a repeat event. A residential block party that closes the street needs a Block Party Permit at least 20 business days ahead, with a petition signed by all affected residents. Events on private property that do not affect the street need no permit and can be booked on a shorter timeline, but early June fills up around the San Mateo County Fair, so book early then. Give us the date, the site, and the guest count, and we size the order and lock the delivery window.
