Commercial cleaning across
San Bernardino County.

Distribution and fulfillment buildings set the pace for the rest of the county's commercial real estate. As CalMatters reported in January 2023, warehouses occupied about 1 billion square feet of the Inland Empire, up from 234 warehouses in 1980 to more than 4,000 — nearly 40 square miles of the region under warehouse roofs. Much of that sits along the I-10, I-15 and SR-60 corridors through Ontario, Fontana, Rancho Cucamonga and Chino.

Alongside the logistics footprint sits a large K-12 and higher-education base — in Ontario alone, two school districts rank among the city's largest employers — plus office space such as Inland Empire Health Plan's operation in Rancho Cucamonga, the city's largest employer at 3,511 people. Janitorial services and day porter services cover the recurring load across all of it.

That concentration — nearly double the national share, per the U.S. Bureau of Labor Statistics — means many San Bernardino County facilities run multiple shifts, and the cleaning visit has to fit around them. A distribution center's admin offices, driver break rooms, restrooms and entry vestibules take the highest foot traffic; the warehouse floor itself usually needs floor care — burnishing, scrubbing, occasional strip-and-refinish on painted concrete or sealed slab — on a slower cycle than a retail or office floor.

• Dock-area vestibules and driver break rooms — highest-frequency touch points, cleaned every shift
• Warehouse mezzanine offices and conference rooms — daily janitorial, weekly detail
• Break rooms and restrooms serving 24-hour operations — multiple passes per day, not once
• Warehouse floor and dock apron — pressure washing and floor maintenance on a scheduled, not reactive, cycle

In practice, that means pressure washing and parking lot sweeping around loading docks, trash enclosures and drive aisles is scoped to contain and properly dispose of wash water rather than let it run to a storm drain. A written scope states who's responsible for that containment before a truck shows up — worth checking in any existing cleaning contract, because it's easy to leave out.
