GMP Janitorial Contractors: What FDA Requires and How to Qualify One

A drug manufacturer can use an outside janitorial contractor, but FDA does not treat that as handing off the responsibility. Under 21 CFR 211.56, sanitation procedures apply to work performed by contractors or temporary employees as well as full-time staff. In practice, the contractor must work to your written procedures, with trained people, approved materials and records your quality unit can stand behind.

This guide explains what the regulations say, how to divide responsibilities, how to qualify a contractor and how to oversee the work afterward. It is written for quality, facilities and procurement teams at pharmaceutical and biotech sites. For the cleaning steps themselves, see our separate guide to cleanroom cleaning procedures.

What FDA Requires

Part 211 does not contain a chapter on janitorial contractors or a set method for qualifying one. The obligations come from general sanitation, personnel and quality provisions, which together shape what a contractor must do at a finished pharmaceutical site:

Regulation	What it says	What it means for a contractor
21 CFR 211.56 (a)	Buildings used to manufacture, process, pack or hold a drug product must be kept clean, sanitary and free of pests, with waste disposed of promptly	The scope reaches storage and holding areas, not only production rooms
21 CFR 211.56 (b)	Written procedures must assign responsibility for sanitation and describe schedules, methods, equipment and materials, and they must be followed	The contractor’s tasks need to be defined in, or traceable to, your written procedures
21 CFR 211.56 (c)	Written procedures are required for cleaning and sanitizing agents and pest control materials, to prevent contamination	Products should be approved before they come on site
21 CFR 211.56 (d)	Sanitation procedures apply to contractors and temporary employees as well as full-time employees	Contract crews are held to the same procedures as your own staff
21 CFR 211.28 (a), (c)	Personnel wear clean, appropriate clothing and protective apparel, and only people authorized by supervisory personnel may enter limited-access areas	Gowning rules apply, and someone must formally authorize crew access
21 CFR 211.25 (a)	Each person engaged in manufacturing, processing, packing or holding must have the education, training or experience for the assigned functions, with continuing CGMP training	The prudent approach is to train and document contract cleaners who work in GMP areas
21 CFR 211.22 (c)	The quality control unit approves or rejects procedures that affect the identity, strength, quality and purity of the drug product	Your quality unit, not the contractor, has the final word on these procedures

International guidance points the same way. ICH Q10, the pharmaceutical quality system guideline, says the company is ultimately responsible for making sure processes are in place to control outsourced activities. For sites supplying Europe, EU GMP Chapter 7 calls for a written contract covering outsourced work, review of its records and results, and the right to audit it.

Sanitation findings are not limited to sterile suites. GMP Compliance reported in 2024 on an FDA warning letter that cited 21 CFR 211.56(a) after inspectors found insects and animal waste in a sampling and product storage area, along with mould-like deposits in the air conditioning system.

Who Is Responsible for What

Most contractor problems come from assumptions about who owns a decision. Write the split down and get both sides to agree to it:

Topic	Your site and quality unit	Janitorial contractor
Procedures	Write, approve and control them	Follow the current version and flag anything unclear
Cleaning agents	Select and approve agents, dilutions and contact times	Use only what is approved, as directed
Training	Define the content and confirm it is complete	Deliver or attend it, keep records and retrain when needed
Access	Authorize named individuals and areas	Send only authorized people and report staffing changes
Records	Define the format, review and retain	Complete them accurately at the time of the work
Validation and monitoring	Own cleaning validation and environmental monitoring programs	Perform work as defined and report problems
Deviations	Investigate and decide on product impact	Report events promptly and support the investigation
Regulatory inspections	Lead them and answer for compliance	Provide records and people on request

Map the Facility Before You Hire

A single scope for the whole site usually fails, because it applies too little control in critical areas or too much in the office wing. Classify each space first. The zones below are a practical starting point, and your quality unit should set the final map.

Zone	Typical spaces	Typical approach
Non-GMP	Offices, conference rooms, cafeterias, visitor areas	Standard janitorial service under a written scope, with tools kept separate from GMP areas
GMP support	Corridors, locker and gowning rooms, warehouses and holding areas, material airlocks	Site procedures, approved products, cleaning logs, and attention to pests, spills and waste
Production and controlled	Compounding, filling, packaging, classified rooms, some laboratories	Exact adherence to SOPs, site-trained crews, gowning qualification, logs reviewed by quality
Equipment and product-contact surfaces	Process equipment, utensils	Usually kept with manufacturing staff, because 21 CFR 211.67 sets separate equipment cleaning requirements

Be explicit about what is excluded. A contractor that is excellent on warehouse floors may not be right for a filling suite, and it is better to find that out on paper.

How to Qualify a Janitorial Contractor

Handle the contractor through your supplier qualification process, scaled to the risk of the areas involved. A workable sequence looks like this:

1. Define the scope by zone. List rooms, tasks, frequencies and exclusions. Our guide to writing a janitorial scope of work provides a framework, and the zone map adds the GMP layer.
2. Walk the site with quality and facilities together. The contractor should see gowning, material flow and the areas it will serve, and should review the relevant SOPs.
3. Assess the company. Review how it trains and supervises people, controls documents, handles complaints and corrective actions, screens employees and manages insurance. For higher-risk areas, carry out a formal audit. General vetting guidance is in our article on choosing a custodial company.
4. Put the responsibilities in writing. Cover the responsibility split, approved materials, deviation reporting times, your audit rights, subcontracting limits and how changes are approved.
5. Train before entry. Crew members should complete and document site training before they work unsupervised in GMP areas.
6. Authorize named people. Record who may enter which areas, and remove access when people leave the account.
7. Approve materials and tools. Confirm agents, wipes, mops and equipment against your approved list, and define where tools are stored.
8. Start under observation. Have quality or a site supervisor observe early shifts and review the first logs before moving to routine oversight.

If this is a replacement rather than a new relationship, plan the handover carefully. Our guide on how to switch commercial cleaning companies covers notice, handover items and worker retention rules.

What Contractor Training Should Cover

Generic janitorial experience does not teach someone why a shortcut matters in a GMP building. At minimum, training should cover:

• Basic CGMP principles and why documentation matters
• The site SOPs for each area the person will clean
• Gowning and hand hygiene, with qualification where your program requires it
• Personnel and material flow, including one-way routes and airlocks
• Approved agents, dilution, contact time and safe handling
• Tool segregation by zone
• Good documentation practices
• How to report spills, damage, pests, missed work and health conditions

Set a retraining trigger for SOP revisions and new agents, as well as a regular refresher. Because cleaning crews often see turnover, the training matrix needs to be checked against the actual roster, not just filed.

The Records to Keep

If an inspector asks how a room was cleaned on a given date, you should be able to show it. Depending on your procedures, the file normally includes:

• The agreement and responsibility split
• Supplier qualification or audit records
• The training matrix and individual training records
• Access authorizations by person and area
• The approved list of agents and tools
• Completed cleaning logs for each GMP area
• Inspection results and corrective actions
• Deviation reports involving the contractor

Logs should be completed at the time of the work by the person who did it. Pre-signing a log, or filling it in at the end of a shift from memory, is a data integrity problem as well as a cleaning problem. Our cleanroom guide lists the documentation quality teams ask for in controlled areas.

Oversight, Deviations and Change Control

Qualification is the beginning of the relationship. Routine oversight keeps it valid:

• Review logs regularly, looking for gaps, identical entries and late completion.
• Walk the areas with the contractor’s supervisor and record the findings.
• Hold periodic performance reviews, with quality in the room.
• Requalify when things change, such as a new supervisor, new areas or a sustained run of problems.

Agree in advance what counts as a reportable event: a wrong or expired agent, a missed clean, a spill, damaged equipment, a gowning breach or evidence of pests. The contractor’s job is to report it quickly and factually. Your quality unit decides what it means for the product.

Changes should flow through your change control process. That includes a different disinfectant, a new tool or a revised frequency, however minor it may seem to the crew.

Red Flags

• Claims to be “FDA approved” or “GMP certified.” Part 211 has no approval or certification program for janitorial companies. Ask what the claim actually refers to.
• Reluctance to work from your SOPs, or a preference for its own standard process
• Bringing products on site without your approval
• New crew members appearing without training records
• Pre-signed or perfectly uniform logs
• No named supervisor, or a supervisor who has never read your procedures
• Offering to assess compliance or product impact on your behalf

Medical Device and Other Regulated Sites

The citations above are specific to finished pharmaceuticals. Medical device manufacturers work under the Quality Management System Regulation at 21 CFR Part 820, which took effect on February 2, 2026 and incorporates ISO 13485:2016, so contractors are normally handled through those purchasing and work environment processes. Dietary supplement and food facilities have their own rules under 21 CFR Parts 111 and 117. The approach in this guide carries over, but the citations do not, so confirm the requirements with your regulatory team.

Frequently Asked Questions

Can a regular janitorial company clean a GMP facility?

Yes for non-GMP areas such as offices, if the work is kept separate from GMP spaces. For GMP areas, the company must be able to follow your procedures, train people on them, use approved materials and keep the required records.

Does FDA certify janitorial contractors?

No. FDA’s Part 211 rules apply to drug manufacturing and contain no certification program for cleaning companies. The manufacturer remains responsible for showing that sanitation meets its requirements.

Do contract cleaners need GMP training?

Those working in GMP areas should have documented training on CGMP basics and the site procedures for their areas. 21 CFR 211.56(d) applies sanitation procedures to contractors, and 21 CFR 211.25 sets training expectations for people engaged in drug manufacturing or holding.

Who writes the cleaning SOPs?

The manufacturer is responsible for them and the quality unit approves them. A contractor can provide practical input, but it should not change a procedure on its own.

Does a pharmaceutical warehouse need GMP cleaning?

21 CFR 211.56(a) covers buildings used for holding drug products as well as making them, so storage areas need to be clean, sanitary and free of pests under written procedures. Our warehouse cleaning checklist is a useful starting point for the general tasks, which you can then bring under your own procedures.

Should the contractor clean production equipment?

Usually not. Equipment cleaning has separate requirements under 21 CFR 211.67 and normally stays with trained manufacturing staff. Any exception should be a deliberate decision by the quality unit.
