APPA Cleaning Levels Explained — and What Each One Costs You to Staff

By Ludovic Martin, Co-Founder, taskforse · Last updated: August 20, 2026

APPA cleaning levels are five defined standards of cleanliness — from Level 1, "Orderly Spotlessness," down to Level 5, "Unkempt Neglect" — published in APPA's custodial staffing guidelines. Each level maps to a staffing density: the cleaner the target, the fewer square feet one custodian can cover, and the more the building costs to maintain.

Key takeaways

  • The five levels run from Level 1 (Orderly Spotlessness) to Level 5 (Unkempt Neglect) — lower number, cleaner building, more labor.
  • Staffing density swings roughly 4–5× across the scale: industry summaries put Level 1 near 10,000–11,000 sq ft per custodian per shift versus 45,000–50,000 at Level 4.
  • On a 100,000 sq ft building at a loaded janitorial cost of about $23/hour, the gap between Level 1 and Level 4 staffing is on the order of $350,000 a year.
  • Most office space is bought at Level 2; Level 3 is the budget compromise. The level belongs in the contract, not in everyone's head.
  • APPA's own examples show the cliff: an office custodian assigned 24,000 cleanable sq ft lands at Level 5 — no amount of effort talk changes the arithmetic.

What are the five APPA cleaning levels?

APPA — the association of physical plant administrators, mostly in education — first correlated cleaning staffing with visible outcomes in its 1992 Custodial Staffing Guidelines, revised in 1998 and republished in 2012 as Operational Guidelines for Educational Facilities: Custodial. The book defines 33 room types, integrates ISSA's cleaning-time data, and names five appearance levels:

LevelNameWhat it looks like
1Orderly SpotlessnessFloors shine, fixtures gleam, no dust or streaks anywhere — showpiece condition
2Ordinary TidinessClean and presentable; minor dust or marks visible only up close
3Casual InattentionNoticeable dulling, dust and smudges; still functional and acceptable at a glance
4Moderate DinginessVisible dirt buildup, dull floors, marred walls — the building looks tired
5Unkempt NeglectSustained neglect; cleaning is essentially reactive only

Descriptions per OrangeQC's summary of the standard and industry guides. The fourth edition also tags each level with the environment it suits — Level 1 "Showpiece Facility" through Level 5 "Crisis" — which is useful shorthand in a client conversation.

The levels were written for campuses, but they have become the industry's common language for cleaning quality anywhere, because they solve a contract problem: "keep the building clean" is an argument waiting to happen, while "maintain Level 2 in patient-facing areas, Level 3 in storage" is a specification you can inspect against.

How does an APPA level map to staffing?

Directly — that is the whole point of the guidelines. The cleaner the target, the fewer cleanable square feet (CSF) one custodian can be assigned per shift.

Exact figures depend on room type and edition, and sources vary. Industry summaries of the APPA benchmarks put Level 1 at roughly 10,000–11,000 sq ft per custodian per shift and Level 4 at roughly 45,000–50,000, with Level 2 in between. APPA's own published examples are room-type specific: a custodian assigned about 17,000 CSF of classroom space should produce Level 2, while an office custodian assigned 24,000 CSF or more should be expected to deliver Level 5. The spread between those two framings is real — treat any single level-to-square-feet table with suspicion and workload by room type, the same way you blend production rates by area.

The direction, though, is never in dispute: moving one level up the scale means detail tasks move from "weekly or on request" to "every visit," and that multiplies hours.

What does each level cost to staff?

Work a 100,000 sq ft building, single shift, five nights. The BLS median janitorial wage is $17.27/hour (May 2024); with a typical labor burden that loads to roughly $23/hour, and a full-time custodian costs about $48,000 a year loaded (2,080 hours). Apply the density bands:

Target levelDensity used (sq ft/custodian)Custodians neededApprox. annual labor cost
Level 1 — Orderly Spotlessness10,5009.5≈ $458,000
Level 2 — Ordinary Tidiness17,0005.9≈ $283,000
Level 3 — Casual Inattention27,0003.7≈ $178,000
Level 4 — Moderate Dinginess47,5002.1≈ $101,000

Densities for Levels 1 and 4 follow the published bands above; Level 2 uses APPA's classroom example; Level 3 is interpolated — an operator rule of thumb to validate against your own workloading, not a published standard.

The lesson survives every quibble about the exact densities: each step down the scale cuts staffing cost by roughly a third to a half, and each step up buys visible quality with real payroll. When a client asks why Level 1 lobby service costs what it costs, this table is the answer — you are not selling effort, you are selling headcount density.

Which level do typical buildings actually buy?

As operator rules of thumb — validate against your market:

  • Corporate offices buy Level 2 for occupied space, with Level 1 expectations in the lobby and executive floor whether they say so or not. Inspection practice reflects this: OrangeQC notes that a contract written at Level 2 should be scored on a 2–5 scale so "spotless" is not silently demanded at a tidiness price.
  • Schools and universities target Level 2 in showcase and health-sensitive areas but under budget pressure often staff much of the campus at Level 3 — shifting service between areas within the same spend rather than raising it.
  • Medical and clinical space is a different regime: patient-facing areas carry disinfection protocols on top of appearance, which is why clinical production rates run 1,800–2,500 sq ft/hr against 3,500–5,000 for offices. Appearance level is the floor there, not the spec.
  • Warehouses and back-of-house are bought at Level 3–4, and honestly so; nobody strips the floor in a loading dock for appearance.

How do I use APPA levels in bids and client conversations?

Three moves, all cheap:

  1. Write the level into the scope, by area. "Level 2 throughout, Level 1 lobby, Level 3 storage" is one sentence, and it converts every future quality dispute into a measurement. It also arms you at renewal: a client demanding Level 1 outcomes on Level 3 staffing is asking for a 2–4× labor difference, and now you have the published scale to show it.
  2. Price level changes as workload changes. When the client wants the building "a bit cleaner," re-run the square-footage math at the new level's density instead of guessing a percentage. A level step is never a 10% tweak.
  3. Inspect against the contracted level. Score walkthroughs on the level scale, attach photos, keep the history per site. That record is renewal ammunition — proof of delivered quality is exactly what most incumbents cannot produce, and its absence is one of the quiet ways contracts lose money and renewals.

The scale's power is that it makes quality a number both sides agreed to. Without it, "the building doesn't look clean" is unanswerable; with it, the answer is a staffing table and a signature.


taskforse is building scope, service levels and per-site inspection history into a CRM for janitorial companies — so the level you sold is the level you can prove at renewal. If defending quality with records instead of arguments appeals to you, join the waitlist.

Frequently asked questions

What are the five APPA levels of clean?
Level 1 Orderly Spotlessness, Level 2 Ordinary Tidiness, Level 3 Casual Inattention, Level 4 Moderate Dinginess, and Level 5 Unkempt Neglect. Lower numbers mean cleaner buildings and more labor. The levels come from APPA's custodial staffing guidelines, first published in 1992 and now standard language for defining cleaning quality in contracts.
What APPA level should an office building be cleaned to?
Most corporate office space is bought at Level 2, Ordinary Tidiness — clean and presentable, minor dust visible only up close. Level 1 is showpiece territory reserved for lobbies and executive floors, and Level 3 is the budget-pressure compromise common in schools and back-of-house areas. Treat those mappings as operator rules of thumb and pin the level in the contract either way.
How many square feet can one custodian clean at each APPA level?
Published figures vary by room type and edition, so sources disagree on exact numbers. Industry summaries put Level 1 near 10,000–11,000 cleanable square feet per custodian per shift and Level 4 near 45,000–50,000, while APPA's own room-type examples show a classroom custodian at 17,000 square feet producing Level 2 and an office custodian at 24,000 producing Level 5. Workload by room type, not by a single campus-wide ratio.
Are APPA levels only for universities?
No. The guidelines were written for educational facilities, but the five appearance levels have become general industry language for specifying cleaning quality in offices, healthcare-adjacent space and government buildings. Commercial contractors use them in SLAs and inspections because they turn 'keep it clean' into a definition both sides can score.
