OSHA's construction toilet standard, 29 CFR 1926.51(c)(1), sets the minimum by crew size. For 20 or fewer workers it requires one facility. Interpretation letters add that a toilet should be reachable in less than ten minutes, and an unsanitary toilet does not count toward the minimum.
Key takeaways
- For 20 or fewer workers, OSHA 1926.51(c)(1) requires one toilet facility on a construction site.
- For 20 or more workers the standard counts toilet seats and urinals per group of workers, and the ratio changes again at 200 workers.
- OSHA's interpretation letters start the access test at whether an employee can reach a toilet in less than ten minutes.
- A toilet in an unsanitary condition does not count toward the minimum, so servicing is a compliance question as well as a comfort one.
- Under temporary field conditions, provision must be made to assure that at least one toilet facility is available.
- Washing facilities are part of the job, and the number of wash stations is a planning decision for the crew.
What does the 1926.51(c)(1) table actually say?
The table sets the toilet count by crew size, and it changes at 20 workers and again at 200. Quote the table as written, because the rows overlap at 20 and a one-unit-per-20 rule is not what it says.
The first row covers 20 or fewer workers and requires one facility. The second row covers 20 or more workers and sets one toilet seat and one urinal per 40 workers. The third row covers 200 or more workers and sets one toilet seat and one urinal per 50 workers. Those are the figures as the standard states them, and they are the figures a site plan should quote. A plan that restates the table in its own words is more likely to drift from the rule when someone later changes the crew list.
Because the first two rows both touch 20 workers, a crew of exactly 20 can read the table either way. Plan to the reading that gives the crew more toilets, check the count against the actual crew on each shift, and keep the table with the site plan so anyone reviewing the site sees the same numbers the crew used. Treat the table as a floor for planning, not as a target to hit on the day the crew is smallest.
How is a toilet 'provided' on a site?
Provision is about access as much as count. OSHA's interpretation letters start the test at whether an employee can reach a toilet in less than ten minutes.
A unit at the far end of a lot does not satisfy the standard just because it exists on the site plan. The letters ask whether workers can get to a toilet quickly from where they actually work. A site that spreads a crew across a long lot, a multi-level structure or a wide framing area needs units placed near the work, not only near the gate or the trailer. The first thing a reviewer will ask is how long it takes a worker on the far side of the site to reach the nearest unit.
This matters most on large sites where the work moves. A unit that was close to the crew in the first week may be far from the new work by the sixth. Re-check distances whenever the work area changes, and move units with the crew rather than leaving them where the first foundation was poured. A construction site toilet plan should be reviewed at each phase change, not only at the start of the job.
When does an unsanitary unit stop counting?
A toilet in an unsanitary condition does not count toward the minimum. That makes servicing a compliance question as well as a comfort one.
The rule is simple to state and easy to miss. A unit that is full, unlocked, out of supplies or overdue for a visit can fail the standard even though it is still standing on the site. The count on paper is not the count in use, and a reviewer who walks the site will check the units themselves rather than the plan. Treat every unit as a unit that has to be fit to use at all times, not only on the day of the servicing visit.
Set the servicing schedule before the first delivery and write it into the rental agreement or the work order. Check units at the start of each shift, and log any unit that needs an extra visit. In Jacksonville heat, a schedule that worked in March may not hold in August, so review it every few weeks and adjust it when the crew grows. A servicing and pumping plan that is written down and checked is the simplest way to keep every unit on the count.
What does 'temporary field conditions' require?
Under temporary field conditions, provision must be made to assure that at least one toilet facility is available. Count that as the floor, then apply the crew-size table above it.
Temporary field conditions describe the early stages of a job, before permanent plumbing is in and the building has a finished bathroom. A new build, a teardown and a remodel can all be in that state for a long stretch. The floor is one facility at minimum, and the crew-size table gives the count once the crew is on the site. A small crew on a remodel can meet the floor with one unit, but only if that unit is reachable and serviced on schedule.
Plan for the transition from temporary to permanent facilities. Permanent facilities can come online in stages, and rented units often stay in service after the building has a toilet. A practical rule is to keep the portable count going until the permanent facility is usable and clean, and not to treat the first working toilet in the building as the end of the need. Write the handover date into the site plan so the crew knows when the portable count is allowed to drop.
What about handwashing on the job?
The standard requires washing facilities on a site, and the number of stations is a planning call for the crew. Place stations near the toilets and the work, and keep them stocked.
Washing is a separate need from toilet use. A crew that works with concrete, mortar, paint or fuel needs water it can use close to the job, and a toilet does not provide it. A handwash station with its own supply serves the crew without a long walk to the trailer, which keeps the work moving and keeps the wash point close to where the dirty work is done.
Heat raises the need. A crew working through a Jacksonville summer drinks more water and washes more often, so stations should be planned for the hottest months rather than the average. Count them alongside the toilets, place them on the same route, and check them on the same schedule. The number of stations is a decision for the crew and the site, not a figure to copy from another job.
How does a large project change the count?
A large site has more crews, more phases and more distance to cover, and the count has to follow the work rather than the first plan. A single plan from day one will be wrong by the middle of the job.
Large projects run in phases: excavation, framing, finishes and then site work, each with a different crew and a different footprint. Each phase can need a different count and a different placement, so plan the toilets by phase and move units with the crews. A plan drawn for the foundation will not describe the finishing stage, and the reviewer will expect the plan to match the work actually under way that week.
Keep a running count on site, updated with the crew list each week. Ask the company how it moves units between phases, and make sure the moves do not leave a crew far from any toilet during the change-over. A move that leaves a crew without a nearby unit for a stretch is exactly the kind of gap the ten-minute access test is meant to catch, and it is easier to prevent than to explain afterward.
What belongs on the site plan?
The plan should show where each unit sits, which crews it serves, the servicing schedule and any accessible placement. Keep it current with the site, not with the first delivery.
A site plan that marks toilets, wash stations and the walking route between them makes the access test easy to answer. Draw the crew areas, the units and the distance from each area to the nearest unit. Label the accessible placement if the job has one, and show the service route the truck will take so that the servicing visits can be checked against the plan.
Update the plan when the work moves, and date each version. A dated plan with the servicing log beside it shows what was provided and when, which is the kind of record a reviewer asks for first. Keep copies on site and in the project file, so the plan is available to the crew, the reviewer and the company at the same time.
Does a Jacksonville job need a Florida permit for its toilets?
The company that pumps and hauls the units needs an annual operating permit under Florida's rule on portable restrooms. That permit belongs to the service company, and the job has to check that the company holds it.
The state rule on portable restrooms and holding tanks is Florida Administrative Code rule 62-6.0101, administered by the Florida Department of Environmental Protection. A service company must hold an annual operating permit for the county where it has an office or storage yard. A company working in a neighboring county with no office there does not need a separate permit for that county, but its service staff must carry proof of the current annual operating permit and of the vehicle inspection.
For a job, the practical step is simple: confirm that the company servicing your units holds the permit and that its staff carry the proof. Ask for both on the phone, and keep a copy in the job file. Local fee and inspection details are not covered in this guide, so take those questions to the company rather than assuming an answer. Florida does not license the trade the way it licenses plumbing, so the permit held by the service company is the document to ask for.
Frequently asked questions
How many toilets does a crew of 20 need?
The table's first row says one facility for 20 or fewer workers. The second row starts at 20 or more and counts toilet seats and urinals per 40 workers. The rows overlap at 20, so a crew of exactly 20 can read either way, and the plan should use the reading that gives the crew more toilets.
Is one portable toilet enough?
Under temporary field conditions, at least one toilet facility must be available, and the crew-size table sets the count above that floor. One unit is only enough for a small crew that can reach it quickly and that is serviced on a schedule the crew can rely on.
How far is too far?
The starting point in OSHA's interpretation letters is whether an employee can reach a toilet in less than ten minutes. A site that places units near the work meets that test more easily than one that puts them at the gate, and the test should be checked again whenever the work area moves.
Do hand-wash stations count as toilets?
No. Washing facilities and toilet facilities are separate needs under the standard, and the count of wash stations is a planning decision for the crew. Put both on the site plan, and check them on the same route and schedule.
Does Florida license portable toilet companies?
Florida does not license the portable restroom trade the way it licenses plumbing. It does require the service company to hold an annual operating permit under rule 62-6.0101, and its staff must carry proof of that permit. Call (888) 351-0294 and ask the company for proof before the first delivery.
Who should I ask about the job site count?
Ask the company that takes your call to set the servicing schedule and the placement, and check the count against your crew list. Keep the schedule and the site plan together in the job file, and update both when the crew or the work area changes.
