How to use this chart:
- Determine how many hours the event will last. If it is multiple days, use the longest day.
- Determine how many people will attend. If there are multiple days, determine the peak day.
- Use the chart to calculate the number of portable restrooms needed for adequate sanitation conditions.
NOTE: If alcohol is being served, add 15 – 20% more restrooms. Add one ADA portable toilet per 20 portable restrooms, or a minimum of one for events open to the public. Adequate hand washing should also be provided with restrooms in all food service areas.
