OSHA Inspections in Maryland Commercial Cleaning (2026)

Who Enforces OSHA in Maryland Commercial Cleaning

Maryland operates one of the 22 full OSHA-approved state plans, covering both private-sector employers and state/local government workers. Maryland Occupational Safety and Health (MOSH) — a division of the Maryland Department of Labor — enforces workplace safety standards from its Hunt Valley office (10946 Golden West Drive, Suite 160, Hunt Valley, MD 21031; (410) 527-4499; MOSH.Complaints@Maryland.gov). The governing statute is the Labor and Employment Article (LE) §§5-101 et seq. of the Maryland Annotated Code, with MOSH standards codified in COMAR 09.12. Federal OSHA retains jurisdiction only over federal employees, the USPS, maritime activities (shipyard, marine terminals, longshoring), and military bases in Maryland.

Top-Cited Standards — Janitorial NAICS 561720

Maryland MOSH standards parallel federal 29 CFR 1910 and 1926. The five most significant standards for janitorial firms are:

1. 29 CFR 1910.147 — Lockout/Tagout: MOSH compliance officers prioritize LOTO in facilities where cleaning crews interact with powered machinery, compactors, and kitchen equipment.
2. 29 CFR 1910.1030 — Bloodborne Pathogens: written Exposure Control Plan, Hepatitis B vaccination offer, and documentation of universal precautions training required.
3. 29 CFR 1910.1200 — Hazard Communication: current SDSs for each cleaning product on each site, plus GHS training before workers use any hazardous chemical.
4. COMAR 09.12.32 — Heat Stress Standard (Maryland-specific): effective September 30, 2024 — the first such standard in the Mid-Atlantic region (see below).
5. 29 CFR 1910.28 — Fall Protection Duty: elevated surfaces, window washing, and exterior building-facade cleaning above 4 feet require guardrails or fall-arrest systems.

What's Specific to Maryland

Maryland's landmark Heat Illness Prevention Standard (COMAR 09.12.32), finalized by MOSH and effective September 30, 2024, is the most operationally significant state-specific requirement for commercial cleaning companies in this batch. Key obligations for janitorial employers:

• Written heat plan required whenever employees work in areas with a heat index at or above 80°F.
• At 90°F+: minimum 10-minute rest every 2 hours in a shaded/cooled area; employer must monitor workers for symptoms.
• At 100°F+: minimum 15-minute rest every hour; direct employee monitoring via buddy system, phone, or radio.
• Written acclimatization schedule for all new hires and returning workers absent 7+ consecutive days.
• Annual training in a language and format all workers understand; retraining after any suspected or confirmed heat-illness incident.

Janitorial crews cleaning non-air-conditioned warehouses, parking garages, or performing outdoor cleaning in Maryland summers are directly subject to COMAR 09.12.32.

2026 Penalty Structure

Maryland MOSH revised penalty amounts effective July 15, 2025:

• Private sector: up to $16,550 per violation; up to $16,550 per day for failure to abate; willful: $16,550 per violation (per revised poster)
• Public sector: up to $16,131 per violation; Willful/Repeat: up to $161,323 per violation; minimum willful: $11,162

Practical First Steps for Maryland Janitorial Companies

1. Immediately develop a written Heat Illness Prevention and Management Plan per COMAR 09.12.32 — if you have crews in non-air-conditioned spaces in summer, this is now a compliance requirement, not a best practice.
2. Document machine-specific LOTO procedures for all powered equipment your crews service or clean around.
3. Ensure chemical SDSs are accessible at each site and that GHS training is documented before new hires start.
4. Post the current MOSH "Safety and Health Protection on the Job" poster (updated July 15, 2025) at all Maryland worksites.
5. File complaints or request compliance assistance through MOSH.Complaints@Maryland.gov or (410) 527-4499.
