OSHA 1910.141: 45 office employees, how many toilets required?

OSHA 1910.141 requires three toilets for 45 office employees. The standard specifies: 1, 15 employees, one toilet; 16, 35, two; 36, 55, three. Your renovation displacing 45 staff to a temporary trailer falls under general industry rules, so three units are mandatory.

Unit types matter for comfort. A standard portable toilet is basic and cost-effective. A deluxe unit with a flushing bowl and sink feels more like an office restroom. For accessibility, the ADA 5 percent cluster rule applies if you cluster units, since three is a cluster, you need at least one ADA-compliant portable toilet. A restroom trailer with multiple stalls might cover all needs in one unit but requires level ground, power, and water access.

Service and placement are key. Office use is steady over weeks or months, so weekly service visits are standard. Ensure the spot is on level ground with truck access for pumping. No alcohol or food service changes the math, OSHA’s minimum is based solely on headcount.

Anyone dealt with a similar office setup? How did you handle the ADA unit alongside standards?

OSHA 1910.141 requires three toilets for 45 office employees. The standard specifies: 1 to 15 employees, one toilet; 16 to 35, two; 36 to 55, three. Since you have 45 employees, three units are mandatory under general industry rules.

For a temporary office setup, consider unit types. A standard portable toilet is basic with a non-flushing holding tank. A deluxe unit offers a flushing bowl and sink for more comfort. If clustering units, the ADA 5 percent cluster rule applies, requiring at least one ADA-compliant portable toilet for accessibility. A restroom trailer with multiple stalls could consolidate needs but requires level ground, power, and water access.

Weekly service visits are standard for office use. Ensure placement on level ground with truck access for pumping. Costs depend on unit type, rental duration, service frequency, and delivery distance.
