Electrical Regulations by State - Pennsylvania



The Department of Labor and Industry, as of January 1st, 2007, has implemented the 2005 NEC.


As of July 9, 2004, all code officials issuing permits and plan reviews must be licensed by the Commonwealth of Pennsylvania. Regulation is left to local jurisdictions.


The Commonwealth of Pennsylvania has no requirements related to the registration, certification or licensure of contractors (or their employees) that are engaged in the construction industry.

Some of Pennsylvania’s 2,565 municipalities have established local licensure or certification requirements for contractors or construction trades people.

Typically, these requirements pertain to home improvement contractors, electrical contractors (or electricians), and plumbing contractors (or plumbers). Since the Commonwealth has no jurisdiction in this matter, the Department maintains no records concerning municipalities that have established licensure or certification requirements. This information can only be obtained by contacting the municipality where construction work will occur.
