Common areas versus tenant suites
Lobbies, corridors, elevators, and shared restrooms should be scoped and priced separately from tenant space so both sides can see what is included.
Building type
Office building cleaning in Greater Philadelphia
The short answer: for office buildings, service frequency is usually the largest single lever on monthly cost, followed by cleanable square footage. Common areas, restroom density, and floor count explain most of what remains.
Office buildings span single-tenant suites to multi-floor multi-tenant properties, and the cleaning program should be scoped to match how the building is actually used.
What shapes the program here
Frequency
Five-night service costs more per month than twice-weekly service, but less-frequent service requires more work per visit because soil and waste accumulate between cleanings.
Floor count and layout
Travel paths, elevator access, and supply staging affect productivity. Two buildings of identical square footage can require different labor hours.
Appearance standards
Lobby presentation, glass, and entryway matting carry disproportionate weight in how a building is judged relative to their share of labor.

Common questions
What does office cleaning cost per square foot?
Cost per square foot is an output, not an input. It falls as buildings get larger and rises with restroom density, food areas, activity, and frequency.
Do you clean multi-tenant office buildings?
Yes. Common areas and tenant suites can be scoped and priced separately for building management and individual tenants.
How often should an office building be cleaned?
Most occupied office buildings are served three to five nights per week. Compare frequencies side by side — monthly investment and average cost per cleaning — to see the tradeoff for your building.
