California Cleaning Services Glossary of Terms
The cleaning industry in California operates under a layered set of regulatory, contractual, and technical terms that carry precise legal and operational meanings. This glossary defines the core vocabulary used across residential, commercial, and specialty cleaning contexts — from licensing and labor classifications to chemical compliance and service agreements. Understanding these terms accurately helps property owners, facility managers, and cleaning businesses navigate California's specific regulatory landscape. The definitions below reflect state-level statutes, California Labor Code provisions, and industry-standard usage.
Definition and scope
A glossary of terms in the cleaning services context is a structured reference document that establishes consistent, operationally grounded definitions for terminology used in service contracts, regulatory filings, worker classification decisions, and compliance documentation. Unlike a general dictionary, an industry glossary assigns jurisdictional specificity — a term like "employee" carries different weight under California Assembly Bill 5 (AB5) than under federal common law tests.
Scope of this glossary: The definitions below apply to cleaning operations conducted within the State of California, governed by California state law including the California Labor Code, Health and Safety Code, Business and Professions Code, and applicable California OSHA (Cal/OSHA) standards administered by the California Department of Industrial Relations (DIR). Terms related to federal OSHA standards, EPA chemical registration, or interstate commerce regulations fall outside this glossary's primary scope, though cross-references are noted where federal and state definitions diverge. This glossary does not cover cleaning operations conducted in other states, even by California-registered businesses.
Core terms defined:
-
Janitorial Services — Routine cleaning and maintenance of interior spaces, including sweeping, mopping, vacuuming, restroom sanitation, and trash removal. Under California's Janitorial Contractor Registration Act (Labor Code §1420 et seq.), any contractor providing janitorial services to a commercial property must register with the Labor Commissioner's Office.
-
Disinfection — The reduction of viable microorganisms on a surface to a level judged safe by public health standards, using EPA-registered disinfectants. Distinct from sterilization (complete elimination of all microbial life) and sanitization (reduction to a regulatory threshold, typically used in food-service contexts per California Retail Food Code).
-
Green Cleaning — Cleaning practices and products that minimize environmental and occupant health impacts. California schools are required by the Healthy Schools Act (Education Code §17608) to use only green-certified cleaning products, a requirement that does not automatically extend to private commercial facilities. See California green cleaning regulations for expanded coverage.
-
Remediation — Abatement or correction of a hazardous condition, such as mold, biohazard contamination, or post-fire residue. Remediation services are regulated more stringently than standard cleaning and may require contractor licensing from the California Contractors State License Board (CSLB) — for example, an asbestos-related abatement requires a C-22 Asbestos Abatement license.
-
Bonding — A surety bond purchased by a cleaning business to protect clients against theft, property damage, or incomplete work. California has no single statewide bonding minimum for general cleaning companies, but janitorial contractors registered under the Labor Commissioner must maintain a $25,000 surety bond (California Labor Code §1429). For broader coverage, see California cleaning service bonding requirements.
-
Independent Contractor (IC) — A worker classified as self-employed rather than an employee. Under AB5 (effective January 1, 2020), California applies the ABC test: a worker is presumed an employee unless the hiring entity proves all three prongs — (A) the worker is free from control, (B) the work is outside the hiring entity's usual business, and (C) the worker is engaged in an independently established trade. Most cleaning workers fail prong B, making IC classification rare and legally risky for cleaning companies.
-
Workers' Compensation — Mandatory insurance covering medical expenses and lost wages for employees injured on the job, required under California Labor Code §3700 for all employers, including cleaning companies with a single employee. See California cleaning company workers' compensation.
-
Proposition 65 (Safe Drinking Water and Toxic Enforcement Act of 1986) — California law requiring businesses to warn consumers before knowingly exposing them to chemicals listed by the California Office of Environmental Health Hazard Assessment (OEHHA) as carcinogens or reproductive toxicants. Dozens of common cleaning chemicals — including formaldehyde, trichloroethylene, and certain quaternary ammonium compounds — appear on the Prop 65 list. See California Prop 65 and cleaning chemicals.
-
SDS (Safety Data Sheet) — A standardized document (formerly called MSDS) providing chemical hazard, handling, storage, and emergency response information for a cleaning product or chemical. Cal/OSHA's Hazard Communication Standard (Title 8, CCR §5194) requires employers to maintain SDS for all hazardous substances in the workplace and to make them accessible to workers during each shift.
How it works
Glossary terms in the cleaning industry function at two levels: regulatory compliance and contractual definition. At the regulatory level, precise terminology determines which licenses a business must hold, which training Cal/OSHA mandates, and which chemicals require disclosure under Prop 65 or the California Cleaning Product Right to Know Act of 2017 (AB 1884 / SB 258). At the contractual level, terms embedded in cleaning service contracts and agreements determine liability, scope of work, and dispute resolution pathways.
A critical distinction exists between cleaning, sanitizing, disinfecting, and sterilizing:
| Term | Pathogen Reduction Target | Regulatory Authority | Typical Setting |
|---|---|---|---|
| Cleaning | Physical removal of dirt/debris | None (baseline practice) | All facility types |
| Sanitizing | Reduction to food-safe threshold | CA Retail Food Code | Restaurants, kitchens |
| Disinfecting | Kill ≥99.9% of listed pathogens | EPA registration required | Healthcare, schools |
| Sterilizing | 100% elimination of all microbial life | FDA (medical devices) | Surgical/medical |
This hierarchy matters operationally: a California medical facility cleaning services contract specifying "disinfection" carries EPA registration and documentation obligations that a standard office cleaning contract does not.
Common scenarios
Scenario 1 — Misclassified IC dispute. A janitorial company contracts with 12 workers as independent contractors, issuing 1099 forms. The California Labor Commissioner investigates and applies the AB5 ABC test. Because the workers perform janitorial services — the company's core business — prong B fails. All 12 workers are reclassified as employees, triggering back payroll taxes, workers' compensation premiums, and potential penalties under Labor Code §226.8, which sets civil penalties between $5,000 and $25,000 per violation (California Labor Code §226.8).
Scenario 2 — Prop 65 warning obligation. A commercial cleaning company uses a floor stripper containing methylene chloride (listed OEHHA carcinogen) in a retail building. Under Prop 65, a clear and reasonable warning must be provided before exposure — either posted signage meeting OEHHA's safe harbor format or direct written notice to the property owner. Failure to warn carries civil penalties up to $2,500 per day per violation (California Health and Safety Code §25249.7).
Scenario 3 — Green cleaning compliance in schools. A school district hires a cleaning contractor for 8 campuses. The Healthy Schools Act requires that all cleaning products be certified by a third-party organization such as Green Seal or UL Environment (EcoLogo). A contractor substituting a non-certified product — even temporarily — violates the Act and exposes the district to parent-notification obligations. Full context appears under California school and educational facility cleaning.
Decision boundaries
When applying glossary terms operationally, three boundary distinctions drive the most compliance errors:
Employee vs. Independent Contractor: Under AB5, the default classification in California is employee. Any cleaning business engaging workers must satisfy all three prongs of the ABC test before treating a worker as an IC. The burden of proof rests on the hiring entity, not the worker. Federal independent contractor tests (IRS 20-factor test, FLSA economic reality test) are irrelevant to California state wage and hour enforcement.
Cleaning vs. Remediation: Standard cleaning services do not require a contractor's license from the CSLB. Remediation work — including mold remediation and cleaning services, asbestos abatement, or lead paint disturbance — triggers CSLB licensing requirements, Cal/OSHA-specific training mandates, and in the case of asbestos, notification to the California Air Resources Board (CARB). Offering remediation services under a general cleaning contract without the correct license violates Business and Professions Code §7028.
Sanitizing vs. Disinfecting (Regulatory Trigger): Sanitizing claims on a product label require EPA registration under FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act), but the specific label claim governs what the product can legally be marketed to accomplish.
