What Class Code 9015 Covers
Class code 9015 applies to commercial building cleaning and janitorial operations including office cleaning, restroom sanitation, floor stripping and waxing, carpet extraction, window washing at ground or reachable height, and general building maintenance cleaning. Commercial janitorial companies that service office buildings, retail centers, schools, medical facilities, and industrial facilities all fall under this classification.
Residential maid and house cleaning services are also generally classified under 9015 when performed by employees of a cleaning company. The residential cleaning exposure is similar to commercial cleaning — the same chemicals, the same physical demands, and similar injury patterns — so the classification treatment is consistent.
High-rise window washing — cleaning windows on exterior surfaces of tall buildings using rope descent systems, scaffold, or swing stage equipment — is a fundamentally different exposure and is NOT included under 9015. High-rise window washing carries its own elevated classification and should be discussed separately with your broker if your company performs exterior high-rise work.
Who This Code Applies To
Janitors, custodians, commercial cleaners, floor technicians, carpet cleaners, window washers (ground and ladder-height access only), and cleaning crew supervisors are all covered under 9015. The workforce demographics of California's commercial cleaning industry are distinctive — a large majority of cleaning workers are immigrants, and Spanish is the primary language for a significant portion of the workforce.
Office administrative staff at a janitorial company — dispatchers, schedulers, account managers, billing staff — should be classified under 8810 (Clerical Office), not 9015. This is a meaningful payroll split for larger janitorial companies with substantial office operations. Separating administrative payroll from field cleaning payroll at audit requires contemporaneous time records, so documentation of who works in the office versus the field should be maintained systematically.
Rate Calculation Example
At the WCIRB advisory rate of $4.22 per $100 of payroll, a commercial janitorial company with $400,000 in field worker payroll faces an estimated gross premium of approximately $16,880 before carrier LCM. High turnover — a defining characteristic of the cleaning industry — creates significant audit complexity, as the actual payroll reported at audit frequently differs from the estimated payroll at policy inception.
Janitorial companies with high turnover often face audit adjustments in both directions. When crews are fully staffed for the full policy period, premium may increase at audit. During periods of understaffing or contract loss, actual payroll may come in lower. Accurate mid-term payroll estimates and regular communication with your broker about payroll changes help avoid large audit surprises in either direction.
Common Misclassifications
High-rise window washing is the most consequential misclassification risk for cleaning companies. A company that performs both ground-level cleaning and exterior high-rise window washing should not classify all operations under 9015. The fall exposure from rope-descent systems and exterior swing stage work is dramatically higher than interior cleaning operations, and carriers write these exposures differently. If your company has crews performing exterior high-rise window washing, disclose this explicitly to your broker and carrier.
Maid service in private homes versus commercial cleaning is generally treated the same under 9015, but some carriers distinguish their appetite between residential and commercial cleaning companies. A company that does primarily residential house cleaning may find different carrier options than one that does primarily commercial janitorial. When applying for coverage, be specific about the residential versus commercial split in your business.
Independent contractor crews used for cleaning work present a significant classification and coverage gap issue. California's AB5 law has made it very difficult to properly classify cleaning workers as independent contractors. A janitorial company that uses 1099 crews without verifying that those crews have their own WC coverage faces both AB5 liability and potential WC premium liability for those workers at audit. Requiring COIs from any subcontracted cleaning crews before they work on your contracts is essential.
Underwriting Considerations
Bilingual safety training materials are a genuine underwriting credit for janitorial accounts with Spanish-speaking workforces. Carriers underwriting California cleaning companies understand that a workforce where many employees have limited English proficiency presents real communication challenges for safety training. An IIPP and chemical safety training program available in both English and Spanish demonstrates that the employer is actually communicating safety information to the workers who need it — not just maintaining a document for regulatory compliance. Some California carriers explicitly credit Spanish-language IIPP programs in their schedule rating.
High employee turnover is both an operational reality and an underwriting concern for janitorial companies. High turnover means a continuous stream of newly hired workers who are at elevated injury risk before they learn the job. Carriers will ask about your average employee tenure, your new hire safety orientation process, and how you document training for workers who may be replaced within weeks or months. Structured new hire safety onboarding with documented completion — even for short-tenure employees — demonstrates risk management maturity.
Subcontractor COI verification is important for commercial cleaning companies that use crews from other companies to fulfill contracts. If you are the general cleaning contractor on a large commercial contract and you use subcontracted cleaning crews, those crews must carry their own WC coverage. Without COIs on file, their workers' injuries may become your WC liability at audit.
Common Injury Types
Slip-and-fall injuries are the most frequent and most ironic claim type for janitorial workers — the same wet floors, freshly waxed surfaces, and cleaning-in-progress conditions that create hazards for building occupants also affect the cleaning crews. Janitors mopping hallways, stripping and waxing floors, and cleaning restrooms work in the very conditions most likely to cause a slip. Non-slip footwear enforcement and wet floor signage during cleaning operations reduce both frequency and liability for employee injuries.
Chemical exposure from cleaning products is a significant but underappreciated injury source. Strong cleaning chemicals — bathroom disinfectants, floor strippers, degreasers, oven cleaners, and drain openers — can cause respiratory irritation, chemical burns to skin and eyes, and occupational asthma with chronic exposure. Workers who mix cleaning chemicals incompatibly (creating toxic chlorine gas by mixing bleach with ammonia or acid cleaners, for example) are at risk of acute poisoning. SDS documentation and chemical safety training are not bureaucratic exercises — they address real and serious hazards.
Back strains from mopping, pushing commercial floor cleaning equipment, and carrying cleaning supply buckets represent a consistent source of musculoskeletal claims. Ergonomic mopping equipment — particularly mop wringing systems and commercial floor machines with proper handles — reduces the strain of repetitive floor cleaning operations. New employee injuries from manual labor they are not yet conditioned for are particularly common in the first weeks of employment.
Risk Mitigation
SDS binder maintenance and chemical safety training are the foundation of a chemical safety program for janitorial companies. Every chemical used in cleaning operations must have a current Safety Data Sheet on file and accessible to employees. Annual chemical safety training — ideally in both English and Spanish — covering the hazards of the chemicals used, proper PPE for each chemical, and emergency response for chemical exposure is both an OSHA requirement and a meaningful risk reduction measure. Carriers offering schedule credits to janitorial accounts consistently cite chemical safety programs as a factor.
Wet floor signage protocols with clear accountability — who places signs, when they are placed, and when they are removed — reduce both employee injuries and the company's general liability exposure from visitor slip-and-falls. A simple written protocol ("signs go out before mopping begins, signs stay until floor is dry, the cleaning worker is responsible for sign placement") is more effective than a general expectation with no specific accountability.
Ergonomic mopping and cleaning equipment reduces the physical strain of commercial cleaning operations. Self-wringing mop systems eliminate the twisting and exertion required to wring traditional mops. Commercial ride-on floor scrubbers for large floor areas eliminate hours of manual mopping. Lightweight vacuum systems reduce back and shoulder strain from carrying heavy traditional units. These equipment investments reduce claim frequency and improve worker retention — two outcomes that compound in their financial benefit to the janitorial company over time.
Best Carriers for Class Code 9015
ICW Group is active and competitive for California janitorial accounts with clean loss histories. EMPLOYERS Insurance has historically had strong appetite for cleaning companies. State Fund writes commercial cleaning accounts broadly and is often an important option for accounts with moderate claims history or high turnover that creates underwriting concerns for admitted carriers.
For larger commercial cleaning companies with revenues above $2 million, program markets that specialize in the janitorial and building services industry may offer better terms and pricing than individual market placement. AmTrust and other specialty carriers have at times operated programs specifically for commercial cleaning companies that bundle WC, general liability, and commercial auto with favorable pricing for accounts that meet minimum safety requirements.
