How far is Foster City from San Mateo?
Foster City sits 4.7 miles east of San Mateo. The drive runs about 9 minutes most days, which means San Mateo Porta Pros can dispatch a truck and have a unit on your site the same morning you call. Construction site services often need speed. We stock standard units, deluxe flushable models, and ADA accessible units in both San Mateo and the surrounding region, so whether you're in Foster City proper or just outside it, we've got inventory ready.
Delivery costs money. For Foster City jobs, expect a delivery fee in the 100 to 150 dollar range each way. Most customers rent weekly or monthly, which spreads that cost and makes the math work. A weekly porta potty rental averages 200 dollars, and a monthly rental runs around 200 dollars as well. If you're renting for a weekend event in Foster City, the unit itself costs 250 dollars for the two days, plus the delivery. Event restroom rental is common work for us.
The permit situation in Foster City is straightforward but worth confirming before you order. Placement in the public right of way needs verifying with the city. We recommend you call ahead or ask your general contractor to check. San Mateo Porta Pros will coordinate with the city if you need us to, but the rule itself comes down to what Foster City permits in that specific block.
What size unit do I need for my Foster City job?
A standard portable toilet holds 60 to 70 gallons and measures about 44 by 48 inches on the ground. It stands roughly 92 inches tall. That fits most sites. If you have 20 workers or fewer on a construction job, OSHA 1926.51(c) requires one toilet facility. If you're running 40 to 60 workers, you'll need two units.
For an event in Foster City, a wedding, festival or corporate gathering, the math is different. You're not under OSHA rules. Count your guests and add one unit per 50 to 100 people as a baseline. If the event runs all day and people are eating, you'll want to go heavier. A wedding restroom rental with 150 guests should have at least two units. Festival restroom rental and concert restroom rental often use three or four because guests drink and the portable toilet gets heavy use.
If Foster City workers are applying paint, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) requires handwashing facilities with soap and towels or a hand drying device on site. Hand sanitizer alone doesn't meet code. San Mateo Porta Pros rents handwashing stations that meet that standard. A single station runs about 100 to 150 dollars per day. Portable sink rental gives you the same setup in a different format.

Do I need an ADA unit in Foster City?
If your event or job site is open to the public or required to comply with Americans with Disabilities Act standards, yes. One accessible unit per cluster of portable toilets is the ADA minimum, and never fewer than one. Foster City hosts public parks and recreation facilities that draw diverse crowds. An ADA accessible porta potty costs 230 dollars per day on average. It's wider, has a grab bar, and features a level entry ramp meeting the 1:12 slope requirement.
If you're a contractor and Foster City has awarded you a public works project, your bid should include an accessible unit from the start. It's easier and cheaper than retrofitting. San Mateo Porta Pros has four accessible units on the roster, and we service all service areas from San Mateo through Foster City and the surrounding communities.
Private events get more leeway. A wedding in a backyard doesn't require an accessible unit unless the venue is required by local law or the event is advertised as accessible. Check with your venue planner or the property owner first.
How often does my Foster City portable toilet get pumped?
Once per week under ANSI/PSAI Z4.3, the industry standard for sanitation. That baseline applies to most sites. Construction jobs with heavy daily use may need twice-weekly pumping. A standard porta potty rental includes one service call per week. If you need an extra pump-out, San Mateo Porta Pros charges a service fee around 60 to 100 dollars per visit.
Can I rent a portable toilet in Foster City for a weekend event?
Yes. A weekend rate in Foster City runs 250 dollars for the unit, plus delivery. A deluxe flushable unit costs more but delivers a better experience for guests. Most event planners in Foster City go with standard units for casual gatherings and deluxe for upscale weddings.
