The administrative procedure represents rules upon which the authorities need to act when deciding on administrative matters. It regulates the relations between the state and the individual or group of people. We are familiar with summary procedures and fact-finding proceedings. The deadlines for an issued decision depend on the aforementioned procedures. It is essential to know that the procedure starts with the submission of a complete application and ends with an issued decision or a procedural decision. The purpose of this thesis is to analyse the duration of administrative procedures in administrative units Laško, Kočevje, Piran and Ljutomer in the years 2015-2017, based on the data from their records and compare the results. In the thesis I used descriptive research method for reading through legislation and other literature from the subject matter and analytical method for data analysis. The results show that there are no delays in the decision-making process in administrative procedures in administrative units. Also, the average time for solving cases does not depend on the number of cases or on the number of cases per individual employee. Despite the approximately equal number of residents within each administrative unit, the number of individual procedures can vary, making it more difficult to be compared. Each administrative unit must manage organising its employees according to the needs of the residents and in this way avoid longer time making a decision.
