Janitorial Suppliers in Northern California (2025 Directory)

They can apply to you. A warning is required when a business knowingly exposes people to a listed Prop 65 chemical above safe harbor levels — and for janitorial work that exposure usually comes from concentrates and the diluted solutions your crew uses on site. Pull the SDS for every product in your closet, compare the ingredients against the current Prop 65 list, and decide from that assessment rather than assuming the label upstream covers you.

Start with the SDS, since that is where the chemical identities live, then check those chemicals against the Prop 65 list. The question is not simply whether a listed chemical appears, but whether the exposure your crew or your client's occupants receive exceeds safe harbor levels. Concentrates and the diluted product at point of use are two different exposure pictures, so evaluate both before you conclude a warning is unnecessary.

Usually no. California's ABC test under AB 5 sets a high bar, and it makes classifying janitorial workers as contractors difficult in practice. The safe default is that your crews are W-2 employees unless a statutory exception clearly and specifically applies to your arrangement. Guessing here is expensive, so treat 1099 janitorial labor as the exception you have to justify, not the starting point.

Two things carry real consequence. First, run the Prop 65 assessment on your product list using SDS documents and the current list, so you know whether a warning obligation exists at the sites you service. Second, settle worker classification against the ABC test before payroll starts, because retroactive reclassification of a crew is far more painful than hiring them as employees on day one.
