How Many Units
The PSAI chart sizes event restrooms by crowd and hours, assuming no servicing during the event:
| Crowd | 1 hr | 2 hrs | 3 hrs | 4 hrs | 5 hrs | 6 hrs | 7 hrs | 8 hrs |
|---|---|---|---|---|---|---|---|---|
| 500 | 2 | 4 | 4 | 5 | 6 | 7 | 9 | 9 |

| 5,000 | 12 | 15 | 20 | 25 | 31 | 38 | 44 | 50 |
| 10,000 | 15 | 25 | 38 | 50 | 63 | 75 | 88 | 100 |
For a five-hour event of 1,000 people, the chart gives 9 units; with alcohol, 10 to 11, and at least 1 accessible unit per cluster.
Who Handles Local Rules
For a special event on public property, a park reservation, or restroom rows on a street or sidewalk, the government to ask depends on where the site is. Of the 86 listed Iowa places, 86 are incorporated. In an incorporated place, ask the city, town, village or borough; in an unincorporated community, ask the county. We don't say whether a permit is needed; each city page names who to ask.
What to Ask For
- Expected attendance, including staff, vendors and volunteers
- Event hours and whether it runs over several days
- Whether alcohol or food will be served
- ADA units (at least 5% of each cluster) and hand-wash stations
- Delivery and pickup windows the venue allows
