According to the Planning Law, advertisements include letters, placards, and hoarding signboard notice, whether illuminated or not. Writing on a shop fascia, writing on a door aimed at drawing attention, road traffic signs, and election posters are advertisements. County governments have the power to grant permission for the display of advertisements in the same way they grant permission for the extension and renewal of leases. However, the display of an advertisement inside a building that is not visible from a street or public place is not a development.
