Legionella Compliance in Michigan: What Facilities Should Know

Legionella Compliance in Michigan

Ohio facility administrators have come to rely on Industrial Water Management for clear guidance on Legionella compliance and water safety. As IWM expands its regional footprint across the Midwest, that same expertise is now reaching Michigan, where healthcare and senior living facilities face their own set of water safety requirements.

Michigan's Water Management Rule

Michigan Administrative Code R 325.45303 requires state-licensed health facilities to implement a water management program built on ASHRAE Standard 188 and the CDC's water management toolkit. The rule calls for a facility-specific risk assessment, defined control measures, and ongoing verification to confirm the plan is working as intended. Nursing homes fall under this state licensure requirement, while independent living and assisted living communities are not separately licensed by the state but remain subject to federal CMS expectations whenever they serve Medicare or Medicaid residents.

Why Federal Requirements Matter Even Without a State Mandate

CMS requires nursing homes and other Medicare and Medicaid certified facilities to maintain a documented water management program that identifies where Legionella and other waterborne pathogens could grow, spells out control measures, and shows evidence of ongoing monitoring. For Michigan facilities, this means water safety compliance is not optional even in settings where state licensure requirements are limited. A well-built water management plan satisfies both the state rule and the federal standard, giving administrators one plan instead of two.

IWM at HCAM 2026

Industrial Water Management will be at the 2026 HCAM Annual Convention & Expo, September 14 to 16 in Grand Rapids, connecting with the facility administrators and maintenance leaders who keep Michigan's long-term care and senior living communities running safely. Stop by to talk through your facility's water management plan, ask questions about ASHRAE 188 and CMS requirements, or learn more about our Legionella testing and remediation services.

Facilities that want a head start on compliance can also claim a Free Memo of Understanding, a simple first step toward a water management plan built around their specific risk factors.
