However, a building permit is not required for the installation, maintenance, or replacement of any load control device or equipment by an electric power supplier, as defined in G.S. 62-133.8, or an electrical contractor contracted by the electric power supplier, so long as the work is subject to supervision by an electrical contractor licensed under Article 4 of Chapter 87 of the General Statutes. The electric power supplier shall provide such installation, maintenance, or replacement in accordance with (i) an activity or program ordered, authorized, or approved by the North Carolina Utilities Commission pursuant to G.S. 62-133.8 or G.S. 62-133.9 or (ii) a similar program undertaken by a municipal electric service provider, whether the installation, modification, or replacement is made before or after the point of delivery of electric service to the customer. The exemption under this subsection applies to all existing installations.
If a developer has not, at the time of issuance of a certificate of occupancy, completed all required site improvements as set forth in subdivisions (1) through (3) of this subsection, the developer shall submit to the local government a signed affidavit detailing the reasons why the required site improvements are not complete, the expected date of completion and compliance, and a statement promising to complete the required site improvements.
