(Replaced by Ordinance No. 174880, effective October 6, 2000.) If no inspection approval has taken place within six months after permit issuance, the permit shall become void, and no further electrical work shall be done at the premises until a new permit has been secured and a new fee paid.  Each time an inspection approval is granted, the permit shall be deemed to be automatically extended for six months, until final approval is granted.  The Director may extend a permit for one period of six months upon finding that the permittee was unable to commence or continue work for reasons beyond his or her control.  Extension requests shall be in writing and must be received by the Director before the permit expiration date.  If an inspection approval has not been granted within this extended time period, the permit shall be void.  A permit that has been expired for six months or less may be renewed provided no changes have been made in the original plans and specifications for such work.  No permit may be renewed if it has been expired for more than six months.  A permit may be renewed only once.  If an inspection approval has not been granted within the time period of permit renewal the permit shall be void.  The renewal fee shall be one half the amount required for a new plumbing permit.
