In Adelaide, a landlord or property manager generally needs to give written notice before a routine inspection, commonly at least seven days and within the permitted notice period. Routine inspections are usually limited to no more than once every four weeks, although different rules can apply for repairs, emergencies or other lawful reasons. The inspection should relate to the property’s condition, not unreasonable searches of your belongings. Check the current guidance from Consumer and Business Services South Australia, or ask a tenancy advice service if the notice seems improper.
