How Do You Find an OSHA Office?

Find out how to locate the right OSHA office by state, and when you may need a federal OSHA office versus a state-plan contact.

Direct answer

To find an OSHA office, use OSHA's offices-by-state directory and start with the state where the jobsite is located. Some states have OSHA-approved state plans, so the correct contact may be a state-plan office rather than a federal OSHA area office.

jobsite state + OSHA office directory = correct federal or state-plan contact

Federal OSHA and state plans can route differently

OSHA coverage is not identical in every state. The office directory helps workers find federal OSHA contacts and state-plan contacts when an OSHA-approved state plan applies.

Find the office

1Identify the state where the worksite is located.
2Open OSHA's offices-by-state directory.
3Review whether the listing points to federal OSHA offices, a state plan, or both.
4Choose phone, email, mail, or in-person contact based on the listing and your filing need.
5Have employer, jobsite, hazard, or retaliation details ready before contacting the office.
