Who enforces OSHA in Wisconsin commercial cleaning
Wisconsin has a unique split jurisdiction. The private sector — including virtually all private commercial janitorial contractors — is covered by federal OSHA through four Wisconsin area offices under OSHA Region V (Chicago): the Milwaukee Area Office (Milwaukee, WI 53203; (414) 297-3315); the Madison Area Office (Madison, WI 53704; (608) 733-2822); the Appleton Area Office (Appleton, WI 54914; (920) 734-4521); and the Eau Claire Area Office (Eau Claire, WI 54701; (715) 832-9019). All private-sector employers are covered by federal 29 CFR Parts 1910, 1926, and 1904. Wisconsin's public sector (state agencies, counties, municipalities, school districts, universities) is separately covered by DSPS — the Wisconsin Department of Safety and Professional Services, Division of Industry Services (1400 E. Washington Ave., Madison, WI 53707; (608) 266-2112) under Wis. Stat. §101.055, which requires DSPS to adopt and enforce safety and health standards at least equal to federal OSHA. A janitorial contractor cleaning a Wisconsin public school answers to both: federal OSHA covers the contractor's employees; DSPS covers the school district's own workers. Federal OSHA retains 11(c) anti-retaliation authority statewide.
Top-cited standards (janitorial NAICS 561720)
- 29 CFR 1910.147 — Lockout/Tagout: The top nationally cited standard for NAICS 561720 (19 federal citations, $322,101 in FY2025 penalties). Wisconsin's large manufacturing sector (food processing in Green Bay, Oshkosh, and Sheboygan; paper mills along the Fox River Valley; automotive parts in Milwaukee) means contract cleaning crews regularly work around powered industrial equipment requiring documented LOTO procedures.
- 29 CFR 1910.1030 — Bloodborne Pathogens: Required ECP, annual training, and HBV vaccine offer for cleaning staff at Froedtert Health, Advocate Aurora Health, and the UW Health system. Wisconsin's large dairy-processing and food-manufacturing sector also creates potential BBP exposure through animal-blood contact in facility cleaning.
- 29 CFR 1910.1200 — Hazard Communication: Full GHS compliance for cleaning chemicals. Wisconsin's chemical and plastics manufacturing corridor (Racine, Kenosha, Appleton) means some industrial-facility cleaning staff encounter concentrated acids, bases, and solvents requiring enhanced HazCom documentation and PPE.
- 29 CFR 1910.28 — Fall Protection: Required for cleaning at heights in Milwaukee's mid-rise commercial core, Fox Valley industrial facilities, and Madison's growing tech-office and university building stock.
- 29 CFR 1910.303 — Electrical (General): Damaged cords, missing GFCI in wet environments, and unauthorized panel access generate regular citations in Wisconsin's food-processing and paper-mill cleaning sector.
What's specific to Wisconsin
- DSPS public-sector program does not assess monetary civil penalties against public employers under Wis. Stat. §101.055 — DSPS issues abatement orders. However, Wis. Stat. §102.57 provides that when a worker injury results from an employer's failure to comply with a DSPS safety order, the employer's workers' compensation obligation increases by 15% (up to $15,000). This creates a tangible financial consequence for public-sector safety violations even without a direct civil penalty.
- DSPS public-sector safety program requires all public employers to submit an annual injury and illness summary (similar to OSHA 300A) through the DSPS electronic system (eSLA portal) by March 1 each year, and post it in the workplace from February 1 through April 1. A janitorial contractor cleaning public-sector facilities must be aware that its client is subject to these DSPS reporting requirements, which may affect contract obligations.
- Wisconsin's OSHA On-Site Consultation Program (WisCon) is administered by the University of Wisconsin — Wisconsin State Laboratory of Hygiene (2810 Walton Commons Lane, Madison, WI 53718; (800) 947-0553 / (608) 226-5240) — available to private-sector employers, free and confidential, separate from enforcement.
- Wisconsin's Clean Indoor Air Act and Right to Know Law are administered by DSPS for public-sector workplaces. The Right to Know Law requires public employers to inform workers about chemical hazards in the workplace — a DSPS-specific compliance obligation for janitorial workers in public-sector buildings.
2026 penalty structure
Private-sector employers (federal OSHA): FY2026 penalty schedule (effective January 15, 2025): Serious violations — up to $16,550 per violation; Willful or Repeat — up to $165,514 per violation; Failure to Abate — $16,550 per day. Public-sector employers (DSPS, Wis. Stat. §101.055): No direct monetary civil penalties — DSPS issues abatement orders. Workers' compensation surcharge under Wis. Stat. §102.57: 15% increase in workers' compensation benefits (up to $15,000) when an injury results from non-compliance with a DSPS safety order. To report a public-sector fatality or mass-hospitalization: DSPS at (608) 445-6558 or (608) 267-9420 (business hours); after-hours: Wisconsin Emergency Management at (800) 943-0003 ext. 2.
Practical first steps
- Determine which federal OSHA area office has jurisdiction over each of your Wisconsin client locations: Milwaukee (southeastern WI), Madison (south-central WI), Appleton (Fox Valley and northeastern WI), or Eau Claire (western and northwestern WI) — each area office may have distinct Local Emphasis Programs affecting your inspection probability.
- If your company provides cleaning services to any public-sector facility (school, county building, state agency), understand the DSPS public-sector program requirements and ensure your workers' safety practices comply with DSPS standards — a DSPS abatement order affecting your worksite can trigger the Wis. Stat. §102.57 workers' comp surcharge.
- Contact the WisCon On-Site Consultation Program at (800) 947-0553 for a free, confidential safety audit before expanding into new industrial, food-processing, or healthcare cleaning contracts in Wisconsin.
- Develop documented LOTO procedures for Wisconsin's food-processing and paper-mill facility cleaning contracts — the Fox Valley paper and packaging industry and Green Bay food-processing sector are among the state's highest-LOTO-exposure environments for contract cleaners.
