License verification guide · Last reviewed July 2026 · By the OhioLicenseCheck.com team
Registered Environmental Health Specialists (REHS, historically "registered sanitarians") are the professionals behind restaurant inspections, water-system checks, and much of Ohio’s frontline public-health enforcement. Their registration is administered under the Ohio Department of Health.
License types under this board
- Registered Environmental Health Specialist (REHS)
About this board
REHS professionals staff local health departments across Ohio, inspecting food-service operations, campgrounds, pools, private water systems, and sewage systems. Their findings carry legal consequences for the businesses inspected, so the registration behind the inspector’s signature is what gives an inspection report its authority.
Consulting firms also employ REHS-credentialed staff for environmental assessments and food-safety programs in the private sector. Businesses hiring such consultants — or contesting an inspection — have reason to confirm the credential in the state record.
Who verifies these licenses?
- •Local health districts hiring and credentialing inspectors
- •Food-service and hospitality businesses engaging food-safety consultants
- •Attorneys reviewing inspection-based enforcement actions
- •Environmental consulting firms validating staff credentials
Verification tips
- An inspection report should trace to a registered specialist or a supervised trainee — the record confirms which.
- Private consultants advertising "sanitarian" services should hold current REHS registration.
- Registration in training status (SIT) indicates supervised practice, not independent authority.
Renewals and expiration
REHS registrations renew on regular cycles with continuing-education requirements. Health districts manage rosters of registrants; consultants manage their own — both benefit from automated expiry tracking.
Frequently asked questions
What does a Registered Environmental Health Specialist do?
They inspect and enforce health standards across food service, water, sewage, pools, and housing. If a health inspector has visited your business, an REHS (or supervised trainee) performed that inspection.
Is "sanitarian" the same as REHS?
Yes — Ohio modernized the title from registered sanitarian to Registered Environmental Health Specialist. Older documents may use the earlier term for the same credential.
