EXECUTIVE SUMMARY
Commercial cleaning contracts often charge for square footage footprints that include vacant areas or unserviced utility spaces, creating 10% to 18% in annual overspend. Output-based auditing aligns cleaning schedules with actual facility occupancy.
Most janitorial contracts price service on a per-square-foot basis, which is simple to administer but rarely reflects the space that actually requires cleaning. A static square footage formula treats every area as if it were in full, daily use — even when it is not.
Vacant offices, storage rooms, mechanical spaces, and portions of the footprint that are rarely occupied all remain in the billed square footage long after their cleaning needs have changed. Because the contract does not automatically adjust as occupancy shifts, the property manager continues to pay for service that is no longer being consumed.
The cumulative effect is an overpayment of 10% to 18% annually — hidden inside a routine invoice that appears unchanged and therefore goes unquestioned.
Restructuring custodial services does not require lowering quality. It requires shifting the basis of billing from a static footprint to actual output and occupancy, so that service levels match what each area truly needs.
Measure which areas are genuinely cleaned and remove vacant or unserviced space from the billing basis.
Align the schedule of cleaning visits with how often each zone is actually used, right-sizing frequency without sacrificing cleanliness.
Move from "clean the building" to specific, measurable tasks so pricing reflects defined work rather than undifferentiated square footage.
Use the corrected footprint and task list to secure market-rate pricing through a competitive review.
