Why does the same crew get two different answers?
Two rules apply to a Florida construction site and you have to satisfy both. Florida Table PR II counts people on site and returns a restroom count. OSHA 29 CFR 1926.51(c) Table D-1 counts employees and returns a count of toilet seats and urinals. Different units of measurement applied to different populations, so they produce different numbers.
We ran both across crew sizes from 10 to 500 to see how far apart they actually sit.
| People on site | Florida Table PR II | OSHA Table D-1 seats | Florida multiple |
|---|---|---|---|
| 10 | 1 unit | 1 facility | 1x |
| 20 | 2 units | 1 seat | 2x |
| 30 | 3 units | 1 seat | 3x |
| 40 | 4 units | 1 seat | 4x |
| 50 | 5 units | 2 seats | 2.5x |
| 100 | 10 units | 3 seats | 3.3x |
| 200 | 20 units | 4 seats | 5x |
| 500 | 50 units | 10 seats | 5x |
The practical consequence
A contractor who sizes a Florida site to OSHA alone will be under-provisioned against the state rule at every crew size above 10. At 200 people the shortfall is 16 units. This is the most common sizing mistake we see, and the county health department is the body that enforces the figure being missed.
Which number governs
The stricter one, which on any Florida site above 10 people is the Table PR II figure. Size to Florida first, then check the result against OSHA, rather than the other way round. It is faster and it lands on the right answer.
How do you size an event?
Florida Table PR I is a two-variable table: attendance and duration together. A 1,000-person event running 8 hours requires 4 units. A 10,000-person event running 10 hours requires 30 units. Duration carries as much weight as headcount, because a crowd that stays ten hours uses a restroom several times over.
Two adjustments experienced planners make
Alcohol raises usage rate materially, and planners routinely add 15 to 20 percent above the code minimum when it is served. Queue tolerance is the second. The code figure is a sanitation minimum, not a queueing target, and a 30 minute line at a wedding is a compliant outcome that nobody wanted.
Daily servicing has to be designed in
Florida requires event units to be serviced at least daily. On a multi-day event a vacuum truck has to physically reach every unit once a day, which is a site plan question you answer before ordering, not on day two.
How many of them have to be accessible?
At least 5 percent of the units at each cluster, with a minimum of one. Where only one unit is provided anywhere, that unit must be accessible.
The phrase people miss is at each cluster
An event with 40 units split across four banks of 10 is not one cluster of 40 needing two accessible units. It is four clusters of 10, and each one needs its own. Sizing accessibility to the event total instead of to each bank is the most common ADA error in event sanitation planning.
The ground counts too
A compliant unit standing on soft sand or loose turf with no firm, stable, slip resistant approach does not meet the standard. The unit and the surface under it are assessed together.
How many hand wash stations does that require?
One for every ten portable restrooms, at special events and at remote locations where food is served. If your event has 22 restrooms, that is three stations, not two.
The food trigger catches out construction sites. A remote job site with a lunch truck or an on-site catered meal falls inside the rule in a way the same site without food does not.

Florida unit counts for construction and remote sites
Florida Administrative Code 64E-6.0101 Table PR II requires 1 portable restroom for 1–10 people, 2 for 11–20, and 3 for 21–30, plus one additional unit for every 10 additional people or fraction thereof.
| People on site | Portable restrooms required |
|---|---|
| 1–10 | 1 |
| 11–20 | 2 |
| 21–30 | 3 |
| Each additional 10 people or fraction thereof | +1 |

OSHA toilet requirements on construction sites
OSHA 29 CFR 1926.51(c) Table D-1 requires 1 toilet facility for 20 or fewer employees; for 20 or more employees, 1 toilet seat and 1 urinal per 40 workers; and for 200 or more employees, 1 toilet seat and 1 urinal per 50 workers.
| Number of employees | Minimum number of facilities |
|---|---|
| 20 or fewer | 1 toilet facility |
| 20 or more | 1 toilet seat and 1 urinal per 40 workers |
| 200 or more | 1 toilet seat and 1 urinal per 50 workers |
Under temporary field conditions, provisions must be made to assure not less than one toilet facility is available. The requirement does not apply to mobile crews that have transportation readily available to nearby toilet facilities.

Florida unit counts for special events
Florida Administrative Code 64E-6.0101 Table PR I scales required portable restrooms by expected attendance and event duration. As published examples, a 1,000-person event running 8 hours requires 4 units, and a 10,000-person event running 10 hours requires 30 units.
| Attendance | Event duration | Portable restrooms required |
|---|---|---|
| 1,000 | 8 hours | 4 |
| 10,000 | 10 hours | 30 |
Table PR I is a graduated table across the full range of attendance and duration. The two rows above are published reference points; confirm the exact figure for your attendance and duration against the rule text or with the county health department.

How many portable restrooms must be ADA accessible
Under the 2010 ADA Standards for Accessible Design, where multiple single-user portable toilet units are clustered at one location, at least 5 percent of the units at each cluster must be accessible and identified with the International Symbol of Accessibility.
| Units in the cluster | Minimum accessible units |
|---|---|
| 1 | 1: the single unit must be accessible |
| 2–20 | 1 |
| 21–40 | 2 |
| 41–60 | 3 |
| 61–80 | 4 |
| 81–100 | 5 |
The rule applies per cluster, not per event. An event with four separate restroom banks has four clusters, and each one needs its own accessible unit.

Frequently asked questions
How many porta potties do I need for 100 people?
For a 100-person construction crew, Florida Table PR II gives 3 units for the first 30 people plus one for each additional 10, which is 10 units. For a 100-guest event over a typical 4 to 6 hours, plan on 2 to 3 units and confirm the exact figure for your duration.
How many porta potties do I need for 500 people?
Table PR I sizes by attendance and duration together. The published reference point of 4 units for 1,000 people over 8 hours puts a 500-guest event of similar length meaningfully below that, and most planners land in the 4 to 8 unit range depending on duration and alcohol service. Confirm your figure with the county health department.
Does OSHA or Florida rule decide the number on a job site?
Both apply and you satisfy the stricter one. Our comparison across crew sizes from 10 to 500 found Florida higher at every size above 10 people, by as much as five times at 200 workers.
Do I need an accessible unit if I only rent one porta potty?
Yes. The 2010 ADA Standards state that where only one portable toilet unit is provided, that unit must be accessible. A single standard unit at a public event does not meet the standard.
How often do the units have to be serviced?
At least weekly at construction and remote sites, at least daily at special events. Those are legal minimums and high-traffic placements routinely need more.
