Frequently asked questions

How many porta potties does OSHA require on a construction site?

OSHA 29 CFR 1926.51(c)(1), Table D-1: 1 toilet for 20 or fewer employees; 1 toilet seat and 1 urinal per 40 workers when there are 20 or more; 1 toilet seat and 1 urinal per 50 workers at 200 or more. Mobile crews with transport to nearby toilets are exempt.

Do construction porta potties need to be ADA accessible?

No. The 2010 ADA Standards exempt portable toilets used only by construction personnel (§203.2). Sites that the public uses are a different matter.
