California Construction Site Toilet Requirements Explained
What Cal/OSHA requires on a California job site, how it differs from federal OSHA, and how heat and farm-labor rules add to it.
How many toilets does Cal/OSHA require on a construction site?
Cal/OSHA Title 8 §1526 requires at least 1 toilet for every 20 employees of each sex on a California construction site. Urinals may count toward the total, but toilets must make up at least half. When fewer than 5 employees work on site, one toilet for all genders is enough.
| Crew | Cal/OSHA §1526 | Federal OSHA 1926.51(c) |
|---|---|---|
| Under 5 workers | 1 all-gender toilet | 1 toilet |
| 20 workers of one sex | 1 toilet for that sex | 1 toilet |
| 40 workers of one sex | 2 toilets | 1 toilet + 1 urinal |
| 100 workers of one sex | 5 toilets | 3 toilets + 3 urinals |
| 200+ workers | 1 per 20 of each sex | 1 toilet + 1 urinal per 50 |

What else does Cal/OSHA require besides the toilet count?
Cal/OSHA also requires job-site toilets to be kept clean, private and stocked with toilet paper. Under temporary field conditions, no fewer than one toilet must be available. Washing facilities must be kept sanitary under federal OSHA 1926.51(f), so most crews add a hand-washing station.
- Weekly service keeps units clean and stocked; see what happens during service.
- Lockable doors provide privacy.
- Add a hand-washing station for crews that eat on site.
How does California's heat rule affect job-site restrooms?
California's heat illness rule, Cal/OSHA §3395, requires shade for outdoor workers once temperatures pass 80°F and high-heat procedures at 95°F. Workers who drink the required water need restrooms close by. Santa Clarita July highs average 93°F, so summer sites should add service visits and shaded placement.
Read Cal/OSHA §3395 and the summer heat tips.
What do farm and field crews need under California rules?
Farm and field crews in California need 1 toilet and 1 handwashing facility for every 20 employees under Cal/OSHA §3457, placed within a quarter-mile walk or 5 minutes, whichever is shorter. Toilets are separate for each sex. Service records must be kept for 2 years.

Job-site rule questions
Does a one-person job site need a porta potty?
Cal/OSHA requires toilet facilities for employees. A self-employed owner with no employees is not covered the same way, but inspectors and clients often still expect one.
Can workers use a nearby business restroom instead?
Cal/OSHA allows nearby toilet facilities only when they are readily available to workers throughout the shift. Most contractors place a unit on site to avoid the question.
Do construction sites need wheelchair-accessible units?
Units used only by construction workers are exempt from the ADA accessible count under §203.2 of the 2010 ADA Standards. Add one when a worker or visitor needs it.
