In my thesis I have presented the process of acquiring the necessary building and usage permit for the building as well as the making of the required documentation which is necessary in the process of acquiring for the building and usage permit. My research is based on a concrete example: removing of the manufacturing building and building of a new construction of a manufacturing commercial building by the Kovit projekti d. o. o., Trbovlje (Kovit projects Ltd., Trbovlje) investors. In the introductory part of my thesis I have pointed out the problems which are often encountered by the investors when insuring the funds for the realization of the planned building. I have also presented the role of the state in helping realizing the investments which have a great influence on the higher gross domestic product growth as well as reduce unemployment and by that ensure a higher quality of life. In the main part of my thesis I have summed up the provisions which refer to the building of an industrial manufacturing and business building from the ZGO-1 law and regulations. I have described the process of acquiring the building permit and have presented the component parts of the necessary project documentation and have listed in which way the documentation is coordinated with the municipal spatial executive instrument which is valid for the treated area of arranging, which is furthermore the base for the investment planning on the land of the anticipated building. Moreover, I have described the process of acquiring the usage permit and all the necessary documentation and its content. I have also pointed out the changes which have occurred during the process of building, the process of technical examination and the purpose of the acquired building permit. In my final findings I have tried to present a few problems which the investor as well as the design engineer run into while acquiring all the necessary permits. I have listed the bad as well as the good experiences while working on my research project and have furthermore pointed out a few improvements which I believe would be good to acknowledge in order to improve the existing system of acquiring the appropriate permits.
