The Pros and Cons of Bringing Janitorial In-House

On paper, the scales look even. In California, each new compliance duty pulls the cons side lower until outsourcing to a registered partner is the decision that pays off.

Executive Summary

Hiring a couple of cleaners and bringing janitorial work in-house can look like a straightforward way to cut a contractor’s fee. Put the hoped-for savings on one side of the scale and the new employer duties on the other, and at first the pans look even.

However, in California, that decision does something else as well: it turns your company into a janitorial employer. From that point forward, Cal/OSHA, the Labor Commissioner, and your workers’ compensation carrier will treat the role for what it is. Janitorial employees work with chemicals, handle wet-floor and restroom cleaning, and, in many buildings, may reasonably be expected to come into contact with blood or other potentially infectious materials.

The savings on paper often disappear once the real requirements are counted:

• Training that is not optional. Employees need Hazard Communication (HazCom), product-specific hazardous materials instruction, and Bloodborne Pathogens training where exposure is foreseeable.
• Documentation that must stay current. That includes Safety Data Sheets available on every shift, an Injury and Illness Prevention Program that addresses the janitorial role, and job-specific Job Safety Analysis sheets.
• Insurance priced for cleaning, not for desks. The correct workers’ compensation classification can carry substantially higher costs than standard clerical or many warehouse categories.
• A labor market that does not sit still. High turnover can make janitorial positions difficult to keep staffed, while workers’ compensation issues and premium reporting add another layer of responsibility.
• PAGA and wage-and-hour litigation. Janitorial has been a frequent target of Private Attorneys General Act claims. Taking the work in-house puts your company, not a vendor, in the defendant’s chair.

Facility leaders often come to us after an audit, a claim, a failed hire, or an unexpected training gap. We see these issues up close and understand how quickly the perceived savings of in-house cleaning can become more complicated. This white paper explains the benefits companies hope to gain by self-performing, the California-specific risks that come with becoming a janitorial employer, and how a fully registered and trained partner can help protect your organization while keeping your facility clean.

Don’t take on a high-risk occupation simply to eliminate a line item. Understand the true cost of in-house cleaning, then contact JaniTek for a side-by-side comparison based on your facility.

Why Companies Consider Taking Janitorial In-House

The case for bringing cleaning in-house is usually built around four points, and there’s some truth to each one.

• Cost control. A monthly service invoice is easy to see. Wages may look cheaper until you factor in burden, insurance, supplies, supervision, and turnover.
• Schedule control. An employee reports directly to your supervisor and can be redirected the same day. That flexibility has value, but it can quickly disappear when that employee calls out.
• Access and security. Some owners prefer having only their own people hold keys and alarm codes. A vetted contractor can provide the same level of security with background-checked crews and documented key control.
• The belief that cleaning is simple. This is where the assumption can get expensive. Commercial janitorial work in California is a regulated occupation, not light housekeeping added to a warehouse or front-desk role.

Those benefits only hold if your company is prepared to operate like a cleaning employer. Most companies aren’t. Their core business is manufacturing, logistics, healthcare, education, distribution, or professional services. Cleaning isn’t their core business.

What Changes the Day Cleaning Is on Your Payroll

California runs its own OSHA-approved State Plan through Cal/OSHA. Those standards are often stricter than federal OSHA standards and apply to every employer, including offices, warehouses, clinics, schools, and plants that hire their own custodial staff.

Once janitorial is in-house, you own:

• A written, site-specific IIPP that actually covers custodial hazards, inspections, and training.
• Hazard Communication under Title 8 CCR §5194, which involves chemical inventory, labels, SDS access, and documented employee training.
• Bloodborne Pathogens compliance under Title 8 CCR §5193 wherever occupational exposure is reasonably anticipated.
• A PPE hazard assessment and employer-paid protective equipment under Title 8 CCR §3380.
• Correct workers’ compensation classification and payroll reporting.
• Wage-and-hour compliance for nights, weekends, and split shifts.
• A Workplace Violence Prevention Plan under Labor Code §6401.9 (SB 553), including after-hours work.

Cal/OSHA serious-violation penalties can reach $25,000 per violation, with higher exposure for willful or repeated violations. Labor enforcement in the janitorial sector has been active for years. Bringing the work inside does not move you out of that environment. It puts you on the employer side.

Required Training: HazCom, Hazardous Materials, and Bloodborne Pathogens

In-house programs often staff the role by adding hours to a warehouse associate, a receptionist, or the first applicant willing to work nights. California training law does not follow that convenience. Training is based on the chemicals used and the exposures reasonably anticipated, not on the employee’s other job title.

Hazard Communication (HazCom) — Title 8 CCR §5194

Every employer whose employees use or may be exposed to hazardous chemicals must maintain a written Hazard Communication program. Commercial cleaning products qualify, including many products marketed as “green.” Disinfectants, bowl cleaners, degreasers, floor finishes, strippers, and glass cleaners routinely carry corrosive, irritant, sensitizer, or combustible classifications.

A compliant program requires:

• A written HazCom plan covering labels, SDS management, and training.
• A current inventory of every hazardous chemical, tied to the matching Safety Data Sheet.
• GHS-compliant container labels, including secondary spray bottles.
• SDS access on every shift, including nights and weekends.
• Training at initial assignment, when a new chemical hazard is introduced, and within 30 days after the employer receives a new or revised SDS.

Training must cover employee rights, where the written program and SDS file are kept; how to read GHS labels and pictograms; the hazards of products in the work area; how to detect a release; and the protective measures employees must use. Materials must match employees’ language and literacy. A one-time English-only slide deck is not a program.

Proposition 65 can add another duty. If products contain listed chemicals known to cause cancer or reproductive harm, clear and reasonable warnings must be provided before exposure.

Hazardous Materials Handling

Most nightly cleaners are not hazardous-materials technicians, and full HAZWOPER certification is not required for routine restroom and office work. That is not permission to skip chemical competence. In-house janitors mix concentrates, pour acids and bases, handle aerosols and solvents, clean up spills they create, and discard product residue. Those tasks require:

• Product-specific SDS training and secondary-container labeling.
• Correct dilution. Over-concentrating disinfectant or bowl cleaner is a frequent cause of burns, breathing problems, and damaged finishes.
• Incompatible-chemical awareness. Mixing bleach with ammonia or acid-based toilet cleaners can release chloramine or chlorine gas.
• A clear stop-work rule when a spill exceeds what the employee is trained and equipped to handle.
• PPE specified by the SDS and a written hazard assessment, provided at no cost.

If the building includes labs, manufacturing, healthcare, or any process that can leave hazardous residue, the janitorial role may cross into higher-tier requirements. That is a site-specific determination, not a guess made at hiring.

Bloodborne Pathogens — Title 8 CCR §5193

Cal/OSHA’s Bloodborne Pathogens standard applies wherever occupational exposure exists: reasonably anticipated contact with blood or other potentially infectious materials (OPIM). The standard is not limited to nurses. Janitorial and housekeeping employees can fall inside it when they clean restrooms, handle sanitary waste, empty trash that may contain sharps, respond to injuries, or work in schools, clinics, gyms, labs, or any facility where that contact is foreseeable.

Where the standard applies, the employer must maintain a written Exposure Control Plan, use engineering and work-practice controls, provide PPE, offer hepatitis B vaccination at no cost, train at hire and at least annually, keep a written cleaning and decontamination schedule, and follow post-exposure procedures. Even where §5193 does not formally apply, an IIPP is not effective if it ignores a discarded syringe or a blood spill in a restroom.

This is a standing medical and training program. Most non-healthcare employers do not already have one. Building it for two or three custodians is disproportionately expensive compared with contracting a firm that already operates the program.

SDS Compliance Is an Operating System, Not a Binder

Employers must have a Safety Data Sheet (SDS) for every hazardous chemical they use, and those sheets must be available to employees on every shift. In-house programs fail this requirement in familiar ways:

• Products are purchased at a big-box store or online with no SDS file created.
• Secondary bottles are unlabeled or marked only with a nickname (“blue stuff”).
• The SDS binder is years out of date, or lives on a drive the night crew cannot open.
• A new disinfectant is added after flu season, or an inspection scare, and nobody updates the inventory, IIPP, or training roster within 30 days.
• Employees cannot explain the pictograms or find first-aid information.

SDS records also drive PPE selection, first-aid planning, spill kits, storage rules, and Proposition 65 warnings. When an inspector, an injured worker’s attorney, or a workers’ compensation examiner asks for the SDS and the training record that matches the product on the cart, “we keep that with the old vendor,” is not an answer if you are now the employer.

Your IIPP and Job Safety Analysis Sheets Must Cover the Janitorial Role

Title 8 CCR §3203 requires every California employer to establish, implement, and maintain an effective written Injury and Illness Prevention Program. There is no size exemption. The required elements are responsibility, compliance, communication, hazard assessment, accident investigation, hazard correction, training, and recordkeeping.

The word that matters is effective. An IIPP written for office or warehouse work does not become effective for janitorial work because someone changed the cover page. Adding custodians means the program must address that role, in that building, with those products and those hours.

Updating the IIPP for janitorial means:

• Naming the person with authority for custodial safety, not only the person who owns the office IIPP.
• Adding janitorial to hazard identification and periodic inspections, including when new chemicals or equipment are introduced.
• Reaching night and weekend cleaners in the languages they use.
• Investigating custodial injuries and near misses on their own terms. A chemical splash is not a lift-truck incident.
• Training before the employee starts the task, and retraining when products or procedures change.

Job Safety Analysis (JSA) sheets should exist for the work actually performed:

• Restroom cleaning and disinfection, including blood or OPIM response.
• Mixing concentrates and filling secondary containers.
• Floor care: mopping, auto-scrubbing, stripping, and finishing.
• Trash and recycling, liner changes, and sharps recognition.
• Vacuuming, dusting, overhead work, and ladder use.
• After-hours work in unoccupied buildings, including workplace-violence and lone-worker risks.
• Outdoor or unconditioned work, where California’s Heat Illness Prevention standard may also apply.

Each JSA should drive the PPE list, the training module, and the inspection checklist. If those three documents do not match, the IIPP is a file, not a program. That gap is exactly what citations and claims later turn on.

Workers’ Compensation: The Classification That Changes the Math

California does not let employers pick a convenient class code. The Workers’ Compensation Insurance Rating Bureau of California (WCIRB) assigns payroll based on the work performed. Janitorial is not clerical work. It is not standard warehouse or administrative work. Treating it as either one is how companies underprice the job and how they get assessed at an audit.

WCIRB advisory pure premium rates effective September 1, 2026, include:

Pure premium is the loss-cost piece only. Carriers add expense loading, often in the 25–50 percent range, then apply the employer’s experience modification. Actual billed rates are therefore higher. Even at the advisory figure, $500,000 of janitorial payroll carries about $38,140 of pure premium before loading and mods. The same payroll coded as clerical 8810 carries about $1,070.

A company that self-performs cleaning inside its own building may fall into the property-operation or “all other employees” class rather than the contractor code 9008. That is not a loophole back to the clerical rate. The exposure — wet floors, chemicals, waste, ladders, repetitive motion — is still there, and the rate still prices far above office or many warehouse categories.

Auditors look at duties, not job titles. A “facilities associate” who spends the shift mopping restrooms and mixing disinfectant is not a clerical employee, even if they log work orders at a desk. A warehouse worker who is “also the cleaner” can pull the higher-hazard class onto payroll that was previously coded as warehouse. If records do not cleanly separate duties, the higher-rated classification can be applied more broadly than expected, including retroactive additional premiums after an audit.

Turnover: The Cost That Never Appears in the First Comparison

The janitorial industry has one of the highest employee turnover rates in the service economy. There is no single official average, and some marketing figures of 200–400 percent circulate without a solid primary source. The documented picture is still severe:

• In widely cited contractor benchmarking (ISSA/BSCAI), 41 percent of building-service contractors reported annual turnover of 50 percent or more. Only about one in five kept turnover under 10 percent.
• Operators commonly report annual turnover in the 50–150 percent range.
• The Bureau of Labor Statistics projects hundreds of thousands of janitor openings nationally each year, driven largely by replacement rather than growth.
• Recruiting, screening, onboarding, uniforms, and lost productivity for a single cleaner commonly run $1,500–$3,000 before that person is competent on your floor plan and chemical set.

High turnover is not only an HR headache. It is a compliance multiplier. Every new hire restarts HazCom training, SDS orientation, Bloodborne Pathogens training, if applicable, IIPP and JSA instruction, workplace violence training, PPE issue, and site security briefing. Every departure creates a coverage gap and a quality dip. A single-site employer with two custodians has no bench. A professional contractor does.

Workers’ Compensation Fraud Risk in the Janitorial Role

Janitorial work sits in a difficult claims environment. The job is physical, often unsupervised at night, and rich in the kinds of incidents that generate frequent claims: slips on wet floors, shoulder and back strains, chemical exposure, and alleged bloodborne incidents. California has one of the most active workers’ compensation anti-fraud programs in the country, and the janitorial sector appears in that record from both directions — inflated or questionable claims, and employer premium fraud through underreported payroll or misdescribed duties.

That is not a stereotype. Public enforcement files include janitorial company owners who were arraigned after investigators alleged more than $2.4 million in underreported payroll and hundreds of thousands of dollars in premium losses. Insurers underwrite this class cautiously because small, frequent claims move an experience modifier quickly, high-turnover crews are hard to document, and the sector has a history of both claim abuse and payroll concealment.

For a company taking the work in-house, that means:

• You inherit the risk profile. Slip, strain, and exposure claims are easier to allege in a wet, chemical, after-hours job.
• You must run claims with discipline. Early reporting, return-to-work options, and documentation matter. Most non-cleaning employers do not have the muscle for a two-person night crew.
• Misclassification is its own problem. Coding custodians as clerical or warehouse staff to suppress premiums is the conduct that premium-fraud units look for.
• One bad claim changes the spreadsheet. A single contested injury can erase assumed contractor-fee savings and then linger in the experience modifier.

Other California Requirements That Attach to an In-House Crew

Training, SDS, IIPP, and workers’ compensation are the center of the risk. They are not the whole list.

• Workplace Violence Prevention Plan (SB 553 / Labor Code §6401.9). Most California employers must maintain a written plan, train employees, and keep a violent-incident log. Janitorial work is often performed alone, at night, in unlocked or semi-public buildings. A daytime office plan that never mentions the night cleaner is incomplete.
• Ergonomics (Title 8 CCR §5110). Repetitive-motion injuries are common in mopping, vacuuming, and liner pulls. A pattern of those injuries can trigger a formal program.
• Heat illness (Title 8 CCR §3395). Outdoor trash runs, unconditioned spaces, and movement between buildings can bring the Heat Illness Prevention standard into play.
• Respiratory protection (Title 8 CCR §5144). If any product or task requires a tight-fitting respirator, a medical evaluation, fit-testing, and a written program are required.
• Wage and hour. Cleaning schedules produce overtime, split-shift, meal-and-rest, and wage-statement risk. California Labor Commissioner actions in this industry have reached into the hundreds of thousands and millions of dollars.
• Harassment prevention and other mandated training. When combined with IIPP, HazCom, Bloodborne Pathogens, and workplace-violence training, the custodial role becomes a standing training calendar rather than a one-hour orientation.

Separately, companies that later return to outsourcing still have duties under the Property Service Workers Protection Act. Contracting with an unregistered janitorial provider can expose the building owner to fines of $2,000–$10,000 for a first violation and $10,000–$25,000 for subsequent ones, plus successor and joint-liability risk. In-house is not a way around California’s janitorial rules. It is a different, heavier set of rules.

PAGA Exposure: Janitorial Has Been a Frequent Litigation Target

California’s Private Attorneys General Act (Labor Code §2698 et seq.) lets an employee sue as a private attorney general for Labor Code violations, seeking civil penalties on behalf of other aggrieved employees. Seventy-five percent of those penalties go to the state; twenty-five percent go to the employees. PAGA is often filed alongside a class action. Even after the 2024 reforms, it remains one of the most expensive employment risks a California employer can take on.

Janitorial has been a frequent — and expensive — target of that litigation. Cleaning schedules produce the exact violations plaintiff’s firms look for: missed meal and rest periods on short or split shifts, off-clock time before or after the posted schedule, unpaid travel between sites, inaccurate wage statements, unreimbursed supplies or mileage, and overtime that does not show up when the building “just needs a little extra.” Those problems tend to be systemic. One missed break policy can be alleged across every pay period for every cleaner.

The industry’s claim history is public. Large cleaning employers have resolved wage-and-hour and related PAGA matters in the eight- and nine-figure range. Smaller janitorial companies routinely settle in the mid-six figures. The California Legislature treated the exposure as distinctive enough to create a rare, industry-specific PAGA carve-out for certain union janitorial employees working under a qualifying collective bargaining agreement (SB 646). That carve-out is narrow. It does not protect a warehouse, office, clinic, or plant that puts two custodians on its own payroll.

Taking janitorial in-house does not reduce PAGA risk. It relocates it. The defendant is no longer a cleaning contractor with payroll systems, timekeeping protocols, and employment counsel built for this workforce. The defendant is your company, and the claims can reach back through the group of custodians who worked the same schedules and break practices. Night work, split shifts, and high turnover make clean time records harder to keep and easier to attack.

A Clearer Cost Picture

A responsible comparison is not “contractor monthly fee versus two wages.” It is the contractor fee versus the full internal stack.

Why This Matters to Building Owners and Managers

Failing to price these duties correctly can lead to unexpected premium audits, untrained employees handling chemicals and restrooms, quality swings every time a cleaner quits, PAGA and wage-and-hour exposure on night and split-shift schedules, and claims that follow the company for years through the experience modifier. In contrast, outsourcing to a registered, trained partner such as JaniTek keeps the operational burden where it belongs: with a cleaning employer that already maintains the programs, the bench, the correct workers’ compensation class, and the payroll practices this workforce requires.

That is why subcontracting done correctly pays off. You are not buying a mop. You are transferring training, SDS control, IIPP and JSA maintenance, classification, recruiting, claims administration, and representative-action risk to a company built to carry them. Self-performing can still be rational for an organization that already has a mature safety function, competitive wages, low turnover, and a finance team willing to model workers’ compensation at the correct class. Those conditions are uncommon outside professional cleaning companies. For everyone else, in-house janitorial work is a compliance project dressed up as a cost-reduction.

JaniTek’s Commitment to Excellence and Compliance

JaniTek Cleaning Solutions is fully registered with the DLSE and maintains the internal programs California expects of a janitorial employer: Hazard Communication and SDS control, Bloodborne Pathogens protocols where the work requires them, IIPP and job-specific safety practices, workplace-violence planning, and workers’ compensation coverage in the correct classification. We invest in training, supervision, and a more stable workforce than the industry average, so clients are not managing chemical carts, claim files, and recruiting pipelines on top of their own business.

Our approach is the same one we take on PSWPA registration: meet the standard, document the work, and give building owners a partner they can verify, not a low bid that shifts risk back onto the facility.

Best Practices Before You Bring Cleaning In-House

Complete this list honestly. A “not yet” is a reason to keep the work contracted.

1. Confirm the correct WCIRB classification for the actual duties, and have your broker confirm the rate and audit treatment.
2. Rewrite the IIPP for janitorial hazards. Do not append a paragraph to an office or warehouse plan.
3. Build JSAs for restrooms, chemicals, floor care, waste, ladders, and after-hours work.
4. Stand up a written HazCom program, a complete chemical inventory, and SDS access on every shift.
5. Train before employees use products, in the languages they speak, and again within 30 days of any new or revised SDS.
6. Determine whether the Bloodborne Pathogens standard applies. If it does, write the Exposure Control Plan before the first restroom shift.
7. Specify PPE by hazard assessment and SDS, stock it, and issue it at no cost.
8. Make sure the Workplace Violence Prevention Plan addresses lone and night cleaning.
9. Budget for 50 percent-plus annual turnover, not for a stable two-person crew that never changes.
10. Decide who investigates a 2 a.m. claim and who watches for fraud indicators.
11. Include supervision, chemicals, equipment replacement, and training hours in the model, not only wages.
12. If you contract instead, verify DLSE registration, insurance, training records, and classification. Unregistered vendors create their own fines under the Property Service Workers Protection Act.
13. Confirm meal-period, rest-period, split-shift, timekeeping, and wage-statement practices before anyone clocks in. Those are the issues that feed PAGA notices in this industry.

Conclusion: Keep Cleaning With a Company Built for the Risk

Taking janitorial in-house in California trades a visible contractor invoice for a less visible bundle of employer duties. Those duties are specific: Hazard Communication and SDS discipline, hazardous-materials competence at the product level, Bloodborne Pathogens controls where exposure is foreseeable, an IIPP and JSA set that describe the real work, workers’ compensation priced for cleaning rather than for desks or warehouse aisles, a labor model that can survive one of the highest turnover rates — and one of the more fraud-exposed claim environments — in the service economy, and the PAGA and wage-and-hour exposure that has followed this industry for years.

The organizations that do this well are cleaning companies. That is their operating system. Outsourcing to a fully registered partner is how building owners keep the building clean without inheriting the occupation. JaniTek exists so that owners in California’s Greater Central Valley and Central Coast do not have to become janitorial employers themselves.
