electrical anything

It is unlawful for anyone except an individual licensed by the City of Philadelphia to install electrical equipment and wiring. The owner of any property wherein any such installation is discovered shall be issued a violation by the Department of Licenses and Inspections. The limited exceptions include replacing devices and fixtures at existing outlets.
Answer in February 2010 by Jim Miraglia of the Department of Licenses and Inspections.
The Philadelphia amended electrical code could lead one to believe that it applied only to individuals in the business of installing electrical equipment. However, in combination with requirements for permits, this is intended to limit electrical installation to properly licensed persons only.
Homeowners shall not receive an electrical permit.
The cost of a permit to correct the violation issued for not having a permit is double the normal value.
Additionally, there are progressively escalating fees charged by the City of Philadelphia for inspection visits by the Department of L&I inspectors.
