Florida porta potty calculator
This calculator returns the number of portable restrooms required by Florida Administrative Code 64E-6.0101 and OSHA 29 CFR 1926.51, plus the accessible units required by the 2010 ADA Standards and the hand wash stations required by Florida rule. Construction figures are exact; event figures are a clearly labelled conservative estimate.
Governing requirement
3 portable restrooms
- Florida Table PR II: 3 units for 25 people on site.
- OSHA Table D-1: 1 toilet seat and 1 urinal (1 per 40 workers).
- Governing figure: the stricter of the two, which is 3.
- ADA accessible units: 1 across 1 cluster, at least 5% of the units in each cluster, minimum one per cluster.
- Minimum servicing: at least weekly under Florida rule.
How this is calculated
Construction figures are exact. Florida Administrative Code 64E-6.0101 Table PR II requires 1 restroom for 1–10 people, 2 for 11–20, 3 for 21–30, plus one for every additional 10 people or fraction thereof. OSHA 29 CFR 1926.51(c) Table D-1 requires 1 toilet facility for 20 or fewer employees, 1 toilet seat and 1 urinal per 40 workers at 20 or more, and 1 per 50 workers at 200 or more. Both apply; the stricter governs.
Event figures are an estimate, deliberately. Florida Table PR I is a graduated table and we will not publish numbers we cannot cite. The two published reference points are 4 units for 1,000 people over 8 hours and 30 units for 10,000 people over 10 hours. This calculator anchors to the stricter of those two, 2,000 person-hours per unit, which means at large attendances it will return a higher number than Table PR I itself. Confirm your exact figure against the rule or with your county health department before you finalise an order.
ADA is per cluster. The 2010 ADA Standards require at least 5% of units at each cluster to be accessible, and where only one unit is provided it must be accessible. Splitting an order into more banks increases the accessible-unit total.
The rules this tool applies, as published
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.

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.

Hand wash station ratio in Florida
Florida requires one hand wash facility for every ten portable restrooms at special events and at remote locations where food is served.

Minimum servicing frequency at construction and remote sites
Florida requires portable restrooms at construction and remote sites to be serviced at least weekly to prevent insanitary conditions.

Minimum servicing frequency at special events
Florida requires portable restrooms at special events to be serviced at least daily. On a multi-day event this means service vehicle access has to be planned into the site layout before the units are ordered.

Why we published this instead of a quote form
Almost every portable restroom site in Florida hides the unit count behind a contact form, which puts you in a position where you cannot check whether the number you are quoted is right. The rules are public. Reproducing them, with a tool that applies them, costs us nothing and gives you the one thing you need before comparing quotes.
If you find an error in how this applies a rule, call (407) 537-0536 and tell us. We will fix it and note the date.
Calculator questions
How does this calculator work out the number?
For construction sites it applies two published tables exactly: Florida Administrative Code 64E-6.0101 Table PR II (1 unit for 1–10 people, 2 for 11–20, 3 for 21–30, plus one per additional 10 or fraction thereof) and OSHA 29 CFR 1926.51(c) Table D-1 (1 facility at 20 or fewer employees, 1 toilet seat and urinal per 40 workers at 20 or more, per 50 at 200 or more). It returns the stricter of the two.
Why is the event number called an estimate rather than the code figure?
Because Florida Table PR I is a graduated table and we only cite published reference points for it, 4 units for 1,000 people over 8 hours, and 30 units for 10,000 people over 10 hours. Rather than invent the intermediate values, the calculator anchors to the stricter of those two, at 2,000 person-hours per unit. At large attendances that returns a higher number than the table itself. Confirm your exact figure with the county health department.
Why does adding more restroom banks increase the accessible unit count?
The 2010 ADA Standards apply the 5% requirement at each cluster, not to the event total. Forty units in one bank needs two accessible units; forty units split across four banks needs four, one per bank. Splitting an order for coverage genuinely increases what accessibility costs.
Does the calculator account for alcohol?
Yes, as a 20% uplift on the event estimate. That is a planning convention rather than a legal requirement, Florida rule does not distinguish, but alcohol service materially raises usage rate and under-provisioning is the most common complaint at events that served it.
Is this a quote?
No. It is a unit count. Porta Potty Rental Florida is a referral service: call (407) 537-0536 with the number this produces and we will route you to portable restroom companies permitted to service your county. We take no payment and add no markup.
