OSHA publishes a table. Most contractors reference it. The table is a floor, not a guarantee.
It assumes uniform forty-hour-a-week usage with average demand. Real jobsites don't operate that way.
Trade-stacked weeks triple effective headcount. Hot weather doubles hydration and demand. Demo days and concrete pours concentrate usage. Overtime stretches the demand window past the table's assumptions.
Working rule for Tamalpais-Homestead Valley: peak daily headcount divided by ten, rounded up. Add a unit if any single day is twenty percent above average. Swap one for a compliant variant if you have food, public access, lead, or asbestos.
This produces a count slightly above OSHA minimum. The cost difference is smaller than one under-rented day on a fifteen-person crew.
Same day before mid-morning. Next morning otherwise. No rush fee.
