Commercial Cleaning
Cleanable Square Foot (CSF)
Cleanable square footage (CSF) is the portion of a building’s floor area that is actually cleaned, excluding walls, fixed equipment, and uncleanable zones, and is the denominator used in accurate cost-per-square-foot pricing.
In Depth
Gross building area overstates the work because it counts space that is never serviced. CSF refines the estimate to floors, restrooms, and surfaces in scope, producing a defensible price and workload figure.
Why It Matters
Pricing off gross area instead of cleanable area distorts bids and makes vendors look cheaper or pricier than they are. CSF is the honest basis for comparison.
