15. Restroom Facilities

SECTION 15

RESTROOM FACILITIES

OSHA and the Louisville Metro Department of Public Health and Wellness require an event producer provide one chemical-type toilet for every 500 people and one handicap chemical-type toilet per every ten units (if permanent restroom facilities are not available at an event venue). If total number of units is less than ten, one handicap chemical-type toilet should be made available.

Louisville Metro cannot provide portable restroom facilities for events. A list of vendors who can

provide these facilities can be found in the Louisville Event Resource Guide (available online at

www.louisvilleky.gov/communityrelations).

Permanent restroom facilities may be available at certain Louisville Metro-owned venues.

(See Venues – Louisville Metro, Section 22) Event Planners may find the following guide helpful

Chart is from the "Sanitarium & Health Official Guide & Portable Restroom Requirements at Special Events and Crowd Gatherings" from the University of Missouri-St. Louis study.

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.

Plan for more if food and beverages are being served and if there are intermissions causing a surge in people seeking restrooms.

If alcohol is being served, add 15-20% more restrooms.

Don’t forget to order handicapped units and hand sanitizers for each unit.

Keep in mind that this is an estimate. One unit provides approximately 200 uses.
