Depending on the location and type of advertising sign, the required project documentation for obtaining a permit may vary. For example, for an advertisement in an unprotected zone in a smaller town in Serbia, an architectural sketch may be sufficient, while in other locations, approvals from various institutes and public enterprises, as well as a project that includes structural calculations, electrical energy calculations, and technical control, may be required—all verified by licensed engineers in the appropriate field.
