What a Ohio business has to have in writing
Ohio's signature contribution is the Data Protection Act, which does not order anyone to do anything but hands a business an affirmative defense in tort if it can show a written cybersecurity program that reasonably conforms to a named framework such as NIST 800-171, ISO 27000 or the CIS Controls.
Insurance licensees face a harder rule: a written information security program under Revised Code chapter 3965 plus an annual compliance certification filed with the Superintendent by February 15.
Employment mandates are light, though the Pay Stub Protection Act added a written earnings statement duty in April 2025 and the Employment Law Uniformity Act made an effective, well-publicised harassment policy the centerpiece of an employer's affirmative defense.
Ohio runs no OSHA State Plan for private employers; its PERRP program covers public employers only, and private workplaces answer to federal OSHA.
Ohio has a rule of its own in 8 of the 14 areas, listed below. We have not checked the other 6 yet. That is not the same as Ohio having no rule there, and you should not read it that way. It means we have not looked.

Ohio rules for a 15–19 person general business
We check the same 14 areas of state law on every state page: breach notification, data security program, consumer privacy law, biometric and health data, harassment prevention, workplace safety programs, workplace violence prevention, insurance data security, state vendor security program, paid leave policies, required postings, pay transparency, licensing and certifications, and other written policies. Federal rules apply in most of these already. What this page adds is whether Ohio has a rule of its own on top. The federal rules every employer carries follow the Ohio rules. Each row names what you must write, post, file or certify, who enforces it, and links to the authority.
Breach Notification 1Who you must tell after a data breach, and how fast
Data Security Program 1A written safeguards program the state requires before anything goes wrong
Harassment Prevention 1A written policy, and in some states annual training, on harassment
Workplace Safety Programs 1Written programs the state safety agency requires beyond federal OSHA
Required Postings 2The notices every workplace in the state must display
Other Written Policies 4Any other document the state makes an employer write or hand out
