Conditions at a Glance
Climate figures: NOAA 1991–2020 normals from the Billings Logan Intl Ap, MT station, about 1 miles away.
Conditions for Events
DOE's Building America map puts Yellowstone County in the Cold climate region (IECC 2021 zone 6B, PNNL county guide). Winters in this region are long enough that freezing, not heat, is usually the main limit on units that carry water.
Freezing Nights
About 142 nights a year drop to 32°F or below, more than three in four U.S. places in our data, so freezing weather covers a large part of the year. Winter events here are cold-weather events: standard units without running water are the dependable choice, with sanitizer inside; if you want sinks or a trailer, ask for winterized or heated models.
Summer Hot Spells
About 32 days a year reach 90°F, more than most U.S. places in our data; hot spells come and go rather than lasting all summer. If the date falls in a hot spell, add a hand-wash station at each row and ask about an extra service visit.
Outdoor Season
Winter, not summer, is the season that limits outdoor events: from late fall into spring, choose units that do not depend on running water, or ask for winterized ones.
Local Settings
At open-field events on dry, exposed ground, ask for units to be staked. For winter events, clear and pack a path for guests and for the service truck before setup.
How Many Units
The Portable Sanitation Association International (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 |
| 1,000 | 4 | 6 | 8 | 8 | 9 | 9 | 11 | 12 |
| 2,000 | 5 | 6 | 9 | 12 | 14 | 16 | 18 | 20 |
| 5,000 | 12 | 15 | 20 | 25 | 31 | 38 | 44 | 50 |
| 10,000 | 15 | 25 | 38 | 50 | 63 | 75 | 88 | 100 |
For a full-day festival, take 5,000 people over six hours: the chart gives 38 units. If alcohol is served, PSAI adds 10–20%, which is 42 to 46 units after rounding up. For accessibility, 5% of 46 is 2.30, which rounds up to 3 ADA units in a single cluster; split into 2 clusters of 23, each cluster needs its own, so 4 ADA units in total.
Ask about servicing during an all-day event. See the PSAI event chart for the full table.
Placement and Access
Put restroom rows on firm, level ground the service truck can reach, away from food prep, with ADA units on an accessible route and hand-wash stations beside the rows.
Dry, Windy Sites
Only about 14 inches of precipitation falls in an average year, in the driest tenth of U.S. places in our data. At open-air fairs, races and lots, a tipped unit is a hazard; ask for anchoring on exposed sites.
Snow and Access
Average snowfall is about 57 inches a year, more than three in four U.S. places in our data, enough to bury a ground-level path several times a winter. Winter events need a cleared, packed path for guests and for the service truck, and an ADA unit needs that path cleared all the way to its door.
Who to Ask About Local Rules
Billings is an incorporated city with its own municipal government. For a special event on public property, a park reservation, or restroom rows on a street or sidewalk, ask the Billings city government before you book what applies.
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 for every cluster (at least 5%, rounded up) and hand-wash stations
- Winterized hand-wash stations for cold-season dates
- A cleared path for guests and the service truck
