Electrical Permit Fee and Process
All applicants for electrical permits shall pay a $10.00 fee to the Permits & Inspection Services Office in accordance with the fee schedule adopted by Resolution of the Board of County Commissioners. Upon approval of an application, the Permits & Inspection Services Office shall provide two copies of the approved permit. One copy shall be provided to the electrical inspector for his use in reporting electrical inspections to the Permits and Inspection Services Office. The second copy shall be retained by the applicant for their records.
All electrical installations requiring a permit through the Permits and Inspection Services Office shall require proper inspections to assure compliance with the provisions of the electrical code. No electrical wiring or installation shall be concealed unless inspected and approved by a certified electrical inspector. All applicable fees covering the cost of inspections shall be paid directly to the Electrical Inspector. Each applicant for an electrical permit shall cause the premises covered by the application to be open for inspection to the Inspector at all reasonable times. Inspections or re-inspections shall be made within a reasonable amount of time after proper notice of the completion of the electrical work to be inspected for approval. A duplicate record of each written approval made by the Inspector shall be filed with the Permits and Inspection Services Office on the electrical permit provided to the applicant. Should the Permits and Inspection Services Office be notified by the Inspector that any electrical work being performed under an approved permit is not being installed in conformity with the electrical code, the Code Official shall have the authority to stop all electrical work and order the removal or correction of said work.
