Every facilities manager has lived the same sequence. The cleaning contract is signed in January after three competitive bids, the first month is flawless, and by April the complaints start arriving in your inbox: restrooms stocked late, trash cans spotted full at 5 p.m., a lobby that somehow always looks clean except when a tenant walks a prospect through it.
The vendor rarely changed. The scope almost never did either. In most agreements I have seen from the vendor side over two decades, the scope of work was inherited from a document written 10 years and four property managers ago, built around a list of tasks rather than a definition of success. A scope like that cannot fail an audit, because it cannot be audited at all. Here is how to write one that can.
List What Everyone Forgets
The weekly task list is the part every scope gets right: restrooms daily, trash daily, vacuuming on a rotating pattern. The failures hide in the line items almost nobody writes down.
Start with high dusting. Anything above eight feet, including vents, ledges, and exposed ductwork, is invisible to occupants week to week and glaringly visible once a quarter. If the scope does not assign it a frequency, it will never happen, and you will discover it during a tour. Next, floor care cycles. The phrase “as needed” is where hard floor and carpet maintenance goes to die. Specify frequencies by surface and traffic zone, then attach square footage so the pricing is anchored in your actual building, not the vendor’s assumptions.
Day porter coverage deserves the same treatment. Fixed porter hours made sense for stable occupancy; hybrid schedules do not. Write coverage as triggers instead: peak traffic days, tenant events above a stated headcount, or seasonal spikes. Finally, decide who owns consumables and weather work. Paper goods, soap, entry matting service, and post-storm entryway recovery cause more invoice disputes than any other category, because each side assumed the other had it.
Write Service Levels, Not Task Lists
A task list tells the vendor what to do. A service level tells the building what to expect, and only the second one can be audited. The conversion is simpler than it looks: Take every task and restate it as an observable condition with a standard and a check.
“Clean glass entry doors weekly” becomes “entry glass free of smudges and handprints at 8 a.m. daily, verified on the morning walkthrough.” “Disinfect restrooms” becomes “restroom touchpoints disinfected twice daily, documented on posted logs.” When the condition is the standard, any inspector, including one who has never seen the contract, can score a visit in minutes.
Then make inspection part of the contract rather than a favor. Quarterly condition audits with photo documentation work for a reason: They create a shared record before anyone is arguing about one. Give the vendor’s supervisor the same scoring sheet you use, and grade together at least once. When a standard is missed, the contract should define the response, whether that is re-performance within 24 hours or a service credit, and the cure window before it counts against the vendor’s record.
Build a 90-Day Probation Into Every Contract
Even a well-written scope needs a proving period. A 90-day probation is not adversarial; it is how both sides learn the building while the relationship is still cheap to exit.
Begin with a baseline condition survey at kickoff: a room-by-room photographic record with simple scores for floors, restrooms, entries, and high surfaces. That document ends every later debate about whether conditions improved. During the probation window, require weekly service reports rather than monthly ones, and hold a joint walkthrough at days 30, 60, and 90 against the baseline. Staffing, chemistry, and scheduling problems surface inside the first two walkthroughs; vendors who will struggle long-term always struggle on camera.
Close the loop with an exit ramp that is explicit: After written notice and a defined cure period, either party may terminate for performance with 30 days’ notice. Vendors who know the ramp exists outperform the ones who learned about it during a dispute.
A scope of work is the only part of a cleaning contract your building will ever experience daily. Tenants judge the art by the lobby, and audits judge the vendor by your paperwork. If the document defines conditions you can verify, season by season, the vendor will meet them, or the next one will.
