In the graduate thesis, I compared the technical norms and regulations governing the parking facilities in Slovenia in the period of the independance of Slovenia in 1991 to the present, with the guidelines in force or previusly applied in Germany in the same period. I did a comparison of the current norms and regulations in Slovenia and the applicable guidelines in Germany with the guidelines which are applicable in this field in the USA in today's time. In this graduate thesis I compared changes in the dimensions of standard passenger cars, parking lots, parking aisles and ramps in the norms and regulations and guidelines within the inside of Germany in the period from 1991 to today, and compare them with the dimensions in the guidelines from the United States to the present time. To facilitate the presentation of the collected data and findings, I conclude the thesis by drawing the layout of basement garage for each of the covered countries by the applicable norms, regulations and guidelines.
