OSHA Inspections in Michigan Commercial Cleaning (2026)

Jurisdiction overview: MIOSHA full state plan

Michigan operates a full state plan covering all private-sector workplaces and state and local government workers. The enforcing agency is MIOSHA, within the Michigan Department of Labor and Economic Opportunity (LEO), headquartered at 530 W. Allegan Street, Lansing, MI 48909; (517) 284-7777 / (800) 866-4674. MIOSHA's General Industry Safety Division covers physical hazards (LOTO, fall protection, electrical); the General Industry Health Division covers chemical/biological hazards (BBP, HazCom, respiratory). The CET Division provides free confidential consultation: (517) 284-7720. MIOSHA has adopted all 29 CFR 1910 and 1926 standards with Michigan-specific modifications.

Inspection priorities for NAICS 561720 janitorial services

• MIOSHA Part 92 (R 325.70001 et seq.) — Bloodborne Infectious Diseases: Michigan's state-specific bloodborne pathogens standard is codified in MIOSHA General Industry Health Standards Part 92, substantively equivalent to federal 29 CFR 1910.1030. Janitorial contractors cleaning Michigan's extensive healthcare system (Henry Ford Health, Trinity Health, McLaren Health Care, Beaumont Health, University of Michigan Health) must maintain a current written Exposure Control Plan, document HBV vaccine offers within 10 working days, and provide annual BBP training with employee-signed documentation.
• MIOSHA Part 430 / R 325.77001 — Hazard Communication (Michigan Right-to-Know): Michigan's HazCom standard in Part 430 (General Industry Health) adopts the federal GHS HazCom standard plus Michigan's three-part Right-to-Know package. Michigan's Right-to-Know Law extends chemical-disclosure obligations to all Michigan employers — including chemical-inventory rights for fire departments (Firefighter Right-to-Know) and community residents (Community Right-to-Know). Janitorial employers must maintain a chemical inventory, SDS binder, written HazCom program, and documented annual training.
• MIOSHA Part 85 (R 408.18501) — Control of Hazardous Energy (LOTO): Equivalent to 29 CFR 1910.147. Michigan's auto-manufacturing and industrial sector (Ford, GM, Stellantis, Magna, Gentex, plus extensive Tier 1/2 supplier base) creates intense LOTO citation exposure for contract janitorial crews at these facilities. Machine-specific procedures and documented annual training are mandatory. This is the highest-penalty citation nationally for NAICS 561720.
• MIOSHA Part 2 (R 408.10217) — Walking-Working Surfaces / Fall Protection: Equivalent to 29 CFR 1910.28. Required for elevated cleaning at Michigan's auto plants, convention centers (Cobo Center / Detroit's TCF Center), and high-rise commercial buildings in Detroit and Grand Rapids.
• MIOSHA Part 451 — Respiratory Protection: Equivalent to 29 CFR 1910.134. Required when cleaning chemical exposures exceed permissible exposure limits (PELs) or when engineering controls are insufficient. Medical evaluation and MIOSHA-required fit-test needed before any tight-fitting respirator use.

Recent enforcement actions

MIOSHA conducts 3,000–4,000 inspections annually. Health Division inspections most frequently cite Part 430 (HazCom) and Part 92 (BBP) — missing SDS files, undocumented training, and stale Exposure Control Plans are top findings. The Safety Division cites Part 85 (LOTO) at manufacturing-facility cleaning operations. Search MIOSHA enforcement records at michigan.gov/leo/miosha/enforcement.

Penalty schedule — MIOSHA current amounts

MIOSHA penalties under MCL 408.1014 are frozen at 2019 levels: Serious — up to $7,000 (vs. federal $16,550); Willful/Repeat — up to $70,000 (vs. federal $165,514). Discretionary reductions: up to 80% for very small employers; 30% good-faith; 10% clean history. Average assessed penalty after reductions: ~$1,333. Michigan SB 49 (2025) proposes raising MIOSHA penalties to federal levels — monitor status at legislature.mi.gov.

Required programs and recordkeeping

• Bloodborne Pathogen Exposure Control Plan — MIOSHA Part 92: Annual review; exposure determination listing all job classifications; HBV vaccine documentation. MIOSHA Part 92 closely tracks 29 CFR 1910.1030 but is enforced by MIOSHA General Industry Health inspectors.
• Written Hazard Communication Program — MIOSHA Part 430 / R 325.77001: Chemical inventory, SDS binder, GHS-labeled containers, annual training. Michigan's Right-to-Know Law requires employers to respond to employee written requests for chemical information within a defined timeframe.
• MIOSHA 300/300A Recordkeeping: NAICS 561720 is not on the MIOSHA partial-exemption list. Janitorial contractors with 11+ employees must maintain logs. MIOSHA requires the 300A to be posted February 1 – April 30 — and unlike federal OSHA, MIOSHA may request 300 logs during routine inspection of any employer, not just those with 11+ employees.

State-specific rules — Michigan's three-part Right-to-Know

• Employee Right-to-Know (MIOSHA Part 92 / Part 430): Workers whose jobs involve routinely using hazardous chemicals have the right to access chemical information. Employers must provide a written chemical inventory, SDS access, a written HazCom program, and annual training.
• Firefighter Right-to-Know: Michigan law requires employers to provide the fire chief with a list of all hazardous chemicals and SDS files within 10 working days of request — janitorial contractors storing industrial cleaning chemicals on client premises must be prepared to respond.
• Community Right-to-Know: Any resident of the employer's county may request chemical SDS information. This applies to janitorial companies maintaining chemical storage at their facilities.

How janitorial contractors prepare for MIOSHA compliance

• Verify that your BBP Exposure Control Plan cites MIOSHA Part 92 (not federal 29 CFR 1910.1030) as the applicable standard — MIOSHA inspectors enforce Part 92, and citing the wrong standard on your compliance documents can indicate you are using a generic out-of-state program not tailored to Michigan requirements.
• Maintain a chemical inventory under Michigan's Right-to-Know Law that is updated whenever new cleaning products are added — be prepared to respond to fire department or community requests for SDS files within the required timeframe.
• Contact MIOSHA's CET Division (517-284-7720) for a free confidential on-site consultation — CET consultants use MIOSHA's own inspection checklists and will identify the same items that an enforcement inspector would cite, without triggering enforcement.
• Monitor the status of Michigan SB 49 (penalty-increase legislation) — if enacted, MIOSHA penalty maximums will rise to federal levels ($16,550 serious / $165,514 willful), substantially increasing compliance risk for unresolved violations.
