Section 410.370 - Alterations; additions1. Signs may have additions or cutouts placed on them. However, for nonconforming and grandfathered conforming signs, the owner of the sign must first grant the Department written certification that he or she will accept the then-existing inventory data of the Department regarding the size of the sign and material of construction and illumination. The inventory description of the Department of the sign must be used solely for the purpose of valuating altered signs.2. Additions, cutouts or illumination may be placed on conforming signs which meet all size, spacing and lighting requirements without prior notification to the Department. Any change which violates the size or lighting requirements must result in permit cancellation.3. No major structural change or addition is allowed when placing approved additions or cutouts on nonconforming or grandfathered conforming signs. The only structural change that is allowed is that required to attach the addition or cutout to the existing sign frame.Nev. Admin. Code § 410.370
