If, upon inspection, it is found that any part of the work does not comply with the provisions of this chapter, the electrical inspector shall post a red tag in the service switch box stating that violations of this chapter have been found to exist and he shall give notice of such violations to the person to whom the permit for the work was issued. When such red tag has been posted and until it has been removed by the inspector, it is unlawful to lath over or otherwise cover and conceal any part of the electrical installation. (Prior code § 16-1-15)
