Installations in buildings other than one-, two- or three-family dwellings must conform to the 2005 edition of the National Electrical Code. The Commercial/Industrial installations must conform to the 2007 edition of the NEC. Local jurisdictions may adopt more stringent requirements.
All buildings to which the state building code applies are subject to inspection by state inspectors employed by the Department of Commerce, or by local inspectors. The Board of Building Standards is responsible for the certification of local inspection departments.
Ohio requires a mandatory state electrical license for contractors (companies) in commercial work. The Ohio Construction Industry Licensing Board (OCILB) administers a test for electrical contractors, and no localities may subsequently require any restriction other than registration from practicing electrical contracting in that locality.
In order to obtain approval from the Board to site for the exam, a contractor must meeting the following requirements:
- Five years (immediately prior to the date of application) experience in the trade, or be an engineer, or have three years of business experience in the construction industry, or other experience acceptable to the Board.
- Be at least 18 years of age;
- be a US citizen or legal resident alien; and
- Never been convicted of a felony.
Continuing education and proof of $500,000 liability insurance is a requirement for license renewal.
No statewide licensing of journeyman electricians.
