Why this matters for compliance
Cal/OSHA sets portable toilet requirements by crew size, counted separately for each sex. In a city where the working population outnumbers residents by more than two hundred to one, the aggregate requirement is enormous and it sits entirely on employers rather than on residential demand.
California Code of Regulations, Title 8, Section 1526 - Toilets at Construction Jobsites
“A minimum of one separate toilet facility shall be provided for each 20 employees or fraction thereof of each sex.”8 CCR 1526(a)
“The number of toilets shall not be less than one half of the minimum required number of facilities.”8 CCR 1526
California requires one toilet facility for every 20 workers, or any fraction of 20, counted separately for each sex. Because the ratio is applied per sex rather than to the crew as a whole, California job sites routinely need close to double the units that federal OSHA would require for the same headcount.
Commonly got wrong: Most contractors and most competitor websites apply the 1-per-20 ratio to total headcount. Cal/OSHA applies it per sex. A 30-person crew split evenly needs two units, not one - and that difference is exactly what gets cited in an inspection.
