Janitorial Inspection Checklist: How to Inspect Commercial Cleaning, Room by Room

What is a janitorial inspection for?

If you manage a building, you’ve probably had a week where the cleaning looked fine on Monday and drew three complaints by Thursday. An inspection is how you find out which week you’re in before your tenants or staff tell you.

A good inspection does three jobs. It tells you whether the work meets the standard in your contract. It gives you and the vendor the same record to talk about, so a disagreement is about a dated photo instead of two memories. And over a few months, it shows you whether quality is holding or drifting.

It isn’t a task audit. A crew can wipe every desk on the list and still leave a room at Level 3, because the list didn’t say what “wiped” should look like. So the checklist below judges outcomes: what you see, touch and smell when you walk in.

Before you inspect: agree the standard

An inspection needs something to measure against. Without it, every score is an opinion.

The most practical yardstick is the APPA five levels of clean, from Level 1, orderly spotlessness, to Level 5, unkempt neglect. Set a target level for each type of space in your scope of work: restrooms, entrances and break rooms at Level 2 in most buildings, offices at Level 2 or 3, storage lower. Our guide to APPA cleaning levels explains what each level looks like and what it costs to hold.

Then agree how you’ll score. There’s no official formula that turns an APPA level into a percentage, and APPA doesn’t publish an audit form, so every facility sets its own. Write the method into the contract before the first walk, so nobody argues about the scale after a bad score.

The janitorial inspection checklist, room by room

This is the part to print. Each line describes what a pass looks like at Level 2, the most common target. If your target for a space is Level 3, a little more dust on ledges and some corner buildup on floors is acceptable. The descriptions follow APPA’s criteria for floors, surfaces, trash and lights, plus the items most inspection programs add for each room.

Restrooms (score these first)

Entrances and lobby

Offices and open work areas

Break rooms and kitchenettes

Corridors, stairs and elevators

High-touch points (check in every room you walk)

Light switches, door handles and push plates, elevator buttons, handrails, faucet handles, shared keyboards and phones where they’re in scope. These should be wiped every clean. If they’re disinfected, ask which EPA-registered product the vendor uses and how long it stays wet, because a disinfectant only works for its full label contact time.

High dusting and lights (check once a month)

Vents and diffusers, the tops of door frames, light fixtures, and burned-out lamps. APPA’s criteria treat dirty fixtures and lamps that are out as a sign of Level 4. High dusting usually runs on a monthly or quarterly schedule in the scope, so inspect it on that schedule.

How do you score a janitorial inspection?

Keep the scoring simple enough that you, your vendor’s supervisor and a new facilities coordinator would give the same room the same score.

A method we’d recommend:

1. Score each item pass or fail against the description for that room’s target level.
2. Score the room as a whole on the APPA scale. If the target is Level 2 and the room looks like Level 2, it passes. If it looks like Level 3, it’s a finding, even if most items passed. Grading on the level scale keeps the score honest. A 90 percent task score can hide a restroom that smells.
3. Weight restrooms more. They’re where complaints start. Cleaning managers report restrooms draw almost half of occupant complaints, with another fifth about paper supplies. Counting each restroom twice in your building score is a reasonable way to reflect that.
4. Report the building score as the share of rooms at or above target, alongside the list of findings. A single percentage with no list tells you nothing to fix.

What’s a good score? There’s no industry standard to point to. Some programs set a threshold in the 85 to 90 percent range, and KIPP Atlanta’s school custodial RFP asked for a 90 percent average on audits. Pick a number in your contract, then watch the trend and the repeat findings, which tell you more than the number does.

How often should commercial cleaning be inspected, and by whom?

There’s no standard frequency either. What works depends on the building and the risk. A pattern that holds up for most commercial buildings:

• Every visit: the vendor’s supervisor inspects before the crew leaves. This is the inspection that catches problems before your staff do.
• Weekly or every two weeks: a short walk by you or your facilities coordinator, focused on restrooms, entrances and whatever drew complaints.
• Monthly: a joint walk with the vendor’s supervisor, using the full checklist and a sample of every room type. Findings get assigned and dated on the spot.
• Quarterly: a short occupant survey, because the people using the building notice things an inspector walking through at 7 a.m. won’t.

Sample rather than walk every room. Walk every restroom in a small building, a few of each other room type, and rotate which ones so the crew can’t predict the route. In larger portfolios, sampling is how inspection programs stay practical: Purdue University’s custodial team, for example, inspects academic buildings twice a year and high-visibility spaces quarterly, and checks new custodians at 30, 60 and 90 days.

What happens when an inspection item fails?

A finding only matters if it gets closed. The federal GSA’s quality assurance model for custodial contracts is a good template, and it’s simple:

1. Record it. Room, item, date, photo, and who inspected.
2. Notify the vendor the same day, in writing.
3. Re-clean. GSA’s model expects deficiencies fixed immediately or by the next visit. Many contracts, KIPP Atlanta’s among them, set 24 hours.
4. Re-inspect the same item after the re-clean, and record the result.
5. Get the cause in writing. Ask the vendor what caused it and what changes so it doesn’t happen again. Under the GSA model, the contractor answers with the cause, the corrective action and how it’ll prevent a repeat.

Watch for the same finding in the same room three walks running. That points to something structural: the scope doesn’t include the task, the crew doesn’t have the time, or nobody on the vendor’s side is checking. That’s the conversation our guide on whether to change your cleaning vendor walks through.

Contracts can also attach a consequence. Public contracts sometimes set a cure period and a fee deduction for repeated failures. One California court’s janitorial agreement, for example, allows 10 business days to cure and a deduction of up to 10 percent of the monthly management fee per failure. Most private buildings don’t need that much structure, but it’s worth knowing the option exists.

Should you use ATP testing?

ATP meters swab a surface and measure organic residue, and they give you a number instead of a judgment call. That’s their appeal. ISSA’s Clean Standard pairs ATP readings with a traditional sight, smell and touch audit for that reason.

Know the limits before you buy a meter. ATP measures residue from both microbes and other organic matter, so it isn’t a germ count. The CDC notes that it’s unclear whether a threshold for a “clean” hospital surface can be set, and that some disinfectants, including bleach, can lower the reading. Used as an occasional spot check on high-touch points, it adds an objective data point. As a pass or fail test on its own, it can mislead you.

Where it earns its place is in facilities where residue on a surface is a health question, not a looks question. At Craddock’s, we use ATP testing occasionally in schools, daycares and medical facilities, and more often when we’re doing deep cleaning or disinfection in those same buildings. We rarely use it in offices or warehouses, where a visual inspection tells you what you need to know. Whether ATP is part of the quality measures gets agreed up front, when we set the cleaning standard and the KPIs for your account.

What your cleaning vendor should hand you

You shouldn’t have to build the whole inspection record yourself. A vendor with a working quality system should give you:

• Dated records of each visit, showing what was cleaned and who checked it.
• Their own inspection results, including the items they found and fixed before you saw them.
• A log of your findings, with the re-clean date and the cause for each one.
• The names of the products used for disinfection, if disinfection is in your scope.

If your vendor can’t produce those, you’re doing their quality control for them.
