Sanitation That Keeps A Job Site Legal
A construction site restroom is the same physical unit as a standard rental, put to work in a much harder setting and specced against a rule rather than a preference. OSHA requires accessible toilet facilities on construction sites, and the ratio it works from is one unit per ten workers, serviced at least weekly. That is the number your general contractor will ask about and the number an inspector will count against. We supply job site sanitation across Marin County on monthly rates with the weekly service visit included, from a single unit on a residential remodel in Fairfax through to banks of units and hand washing stations on multifamily work in San Rafael. Delivery is one to two business days, the rental is month to month, and units come back the week you finish rather than at the end of a term you are still paying for.
Why Contractors Stay With Us
Site sanitation is a small line on a construction budget and a large problem when it fails. A missed service on a Monday means eighteen people dealing with it on Tuesday, and the super who has to make that phone call remembers which company made it necessary. We run fixed service days rather than rolling windows, our drivers know which Marin addresses need the smaller truck, and we would rather tell you a unit cannot be reached where you want it than quietly skip it for three weeks. Contractors who move between towns here end up consolidating onto one vendor for that reason.
- Fixed weekly service days, so your site knows when the truck comes and can keep the access clear.
- One to two business day delivery across the county, and same-day out of our San Rafael yard when a truck is already loaded.
- Monthly rates that include four service visits, with no separate delivery or collection charge at either end.
- We spec the unit-to-worker ratio with you rather than selling one unit and letting the site outgrow it.
- Units repositioned as the job moves, which matters on multifamily and balcony work where the crew shifts every few weeks.
- Standard, ADA and enclosed units off one yard, so a site that needs a mix gets it on one invoice.
Reasons A Job Site Needs Its Own Restroom
Beyond the obvious, these are the situations that make it a requirement rather than a courtesy:
OSHA requires it above a certain crew size
The federal construction standard requires toilet facilities on site, working from one unit per ten workers. Below twenty workers that is one unit; above that the count rises. Sites without it get cited, and a citation is expensive next to a monthly rental.
The general contractor will not let you start without it
On any managed site in Marin, sanitation is part of mobilization. Subs who show up without it lose a day. If you are the GC, it is normally one of the first things on the ground.
The building has no plumbing yet or no longer has any
Ground-up construction has no facilities until well into the build, and a gut remodel loses them on day one. Both leave a window of months where the only option is a rental.
Crews are losing time driving to find a bathroom
Twenty minutes each way, several times a day, several people. That adds up to real money within a week, and it is the calculation that usually ends the debate about whether to rent.
Neighbors are complaining
This comes up constantly on residential streets in Mill Valley, San Anselmo and Fairfax. It is the fastest route from a routine job to an unhappy code enforcement visit, and a unit on site is the entire fix.
The site is remote or spread out
Road work, utility jobs, ranch and vineyard work, trail crews. When the crew is a mile from the nearest building, sanitation has to travel with them, and we can reposition a unit as the work moves along.

How We Work
Quote on the phone, delivery in two days, weekly service on a fixed day, pickup when you say.
1. Site walk or a phone spec
For most jobs a phone call is enough: crew size, duration, address, and whether a truck can get within twenty-five feet. On larger or awkward sites we come out, because getting the placement wrong on a six-month job costs more than the visit.
2. Delivery and placement
Units are set where they will still be reachable in month four, not just week one. That usually means near the site entrance rather than in the middle of a pad that is about to be built on, and it is the single most useful thing we bring to a first delivery.
3. Weekly service on a fixed day
Pump out, wash down, recharge the deodorizer, restock paper and sanitizer. Ten minutes, nobody needs to be present, and the same day every week so it can be planned around.
4. Scale up, reposition, or collect
Headcount doubles and we add a unit. The crew moves to the far end of the site and we move the unit with them. The job finishes and we collect, with the removal already inside the price.
Job Site Sanitation In Detail
The things that come up on real Marin job sites:
How many units a site needs
OSHA works from one unit per ten workers on a construction site, serviced at least weekly. That is the floor rather than the target: a site with twelve people on one unit will be unpleasant by Thursday. Where a crew has a lot of women on it, or works long shifts, we usually suggest going a unit above the minimum.
Hand washing on site
OSHA 1926.51 requires accessible hand washing on construction sites, and a sanitizer dispenser inside the toilet does not satisfy it on its own. A separate portable hand washing station beside the units is the standard answer and is what inspectors expect to see.
Monthly and long term rental rates
Construction rentals are priced monthly with four service visits included, and the per-day cost is a fraction of an event rate. Most Marin jobs run three to six months. There is no term commitment beyond the first month and no charge for finishing early.
Securing units on open sites
Units on unfenced sites get used by the public, tipped over on Friday nights, and occasionally tagged. Staking, siting them inside the fence line and positioning them where they are visible from the street all help. Where a site keeps having trouble we will swap the unit rather than keep repairing it.
Multifamily, balcony and repipe work
These jobs move around a building for months, which makes a fixed placement useless by week six. We reposition units as part of the rental rather than charging a move fee, which is why this kind of work makes up a lot of our Larkspur and Greenbrae route.
Accessible units on public and commercial work
Public agency contracts and many commercial GCs require an accessible unit on site regardless of crew composition. That is a different unit with a ramp and grab bars, covered on the ADA portable restroom page, and it needs a firm level pad to actually be usable.
Winter access on Marin sites
A unit that sat on hardpack in September can be in six inches of mud in February. On long rentals we will move it to gravel, a plywood pad or the road edge before winter rather than lose service stops, and it costs nothing to do it that way round.
What Job Site Sanitation Costs
A standard unit on a Marin construction site runs roughly $150 to $250 a month with weekly service included. A unit plus a hand washing station is typically $225 to $350. What moves it:
- How many units. Additional units on the same site are cheaper than the first, because the delivery and the service stop are already happening.
- Service frequency. Weekly is included in the monthly rate. Twice weekly costs more and is worth it above roughly fifteen people per unit.
- Unit type. Standard is the baseline. Accessible units cost more, and enclosed units more again, which matters on occupied-property remodels.
- Duration. The monthly rate is the same in month one and month six, so long jobs are where the economics work. Anything under a month is priced as a short-term rental instead.
- Location and access. Nothing extra across our nine towns. Hillside and canyon addresses that need a smaller truck take longer to service and are quoted accordingly.
- Hand washing. A station is a separate line, and on any site with a crew it is a requirement rather than an upgrade, so it belongs in the budget from the start.
Quotes are flat monthly numbers with the delivery, the weekly servicing and the final pickup inside them. If the job is short or a one-off, the standard porta potty rental page covers the shorter-term pricing, and the full range of units we run across the county is on our Marin portable restroom rental overview.
Frequently Asked Questions
Do you provide restrooms for construction sites?
Yes, and it is most of what we do. OSHA requires one unit per ten workers on job sites, serviced at least weekly, and that is how we spec an order. We deliver across Marin in one to two business days, run a fixed weekly service day, and rent month to month so units go back the week the job finishes.
How many portable toilets do I need for my crew?
Start from one unit per ten workers. A ten-person framing crew needs one; a twenty-five person site needs three. Long shifts, a crew with a lot of women on it, or a site where the units are a long walk from the work all argue for going one above the minimum, because the alternative is people driving off site to find a bathroom.
Is a hand washing station required on a construction site?
In most cases yes. OSHA 1926.51 requires accessible hand washing facilities, and the sanitizer dispenser inside the toilet does not satisfy it by itself. A separate station beside the units is what inspectors look for, and it is what we supply as standard alongside job site orders.
Is there a minimum rental period for a job site?
One month. That is the industry standard for construction and it is how our monthly rate is built. After the first month it is genuinely month to month, so a job that wraps up early does not carry a cancellation charge.
Can you move the unit as the job progresses?
Yes, and on multifamily, balcony and repipe work we expect to. Repositioning within the same site is part of the rental rather than a billed move. Just give us a day or two of notice so it goes on the route properly.
What happens if the unit gets tipped over or vandalized?
Call us and we will come out. On an unsecured site this happens occasionally and we would rather deal with it than have your crew try to right a full unit. Normal wear and the odd knock are on us; repeated deliberate damage is a conversation about siting and, if needed, a swap.
How much room does the delivery truck need?
A standard unit needs roughly a 4×4 ft footprint on level ground. The truck needs at least 10 ft of clearance width and overhead access, and the service hose runs about twenty-five feet from where it can park. On tight Marin streets we bring a smaller truck, but the hose distance is the constraint that does not change.
Need a restroom in Marin?
Dates, numbers and an address are all we need. We call back inside one business hour with a free estimate and a flat price.
