Baltimore runs three commercial cleaning markets that a single rate cannot describe. There is a very large hospital and biomedical sector, a working port with the industrial space attached to it, and a downtown of old building stock where access costs are real. Only the third resembles what the published commercial rates in this record measured.
Hospital and biomedical space is a clinical specification
Cleaning in a teaching hospital is an infection-control function: zoned by risk rather than by floor, audited rather than inspected, with terminal cleaning as a defined procedure. None of the per-square-foot figures in this record applies, and a bid built on them has misread the building.
Port and industrial space is crew hours
Warehousing, maintenance and terminal space are priced on machine hours or crew hours against an access window that operations controls, with the soil named in the scope. It belongs on its own schedule, split from any office portion.
The old downtown carries access costs
Narrow service access, stairs instead of service lifts, original floor materials and frequently no dedicated janitorial provision consume crew time before cleaning happens. That is a genuine premium and it is invisible in a per-square-foot comparison against modern suburban space.
Winter salt and the entrance line
Mid-Atlantic winters put grit and de-icing salt through entrances for months. Matting, a raised winter entrance frequency and a spring floor programme belong in the contract as a named seasonal shape rather than as an annual argument.
Questions people ask about commercial cleaning baltimore
Do the published figures apply to a hospital?
No. They are general commercial and office rates; clinical space is specified and staffed differently and none of them measured it.
Should one contractor cover office and port space?
Usually, with two schedules. A blended rate hides which half the money is going to.
Is the old stock more expensive to clean?
Per square foot, generally yes, and the reason is access rather than standard.
