In my thesis I have described the course of work at preparing the project documentation which in accordance with valid regulations needs to be made for the acquirement of building permit and usage permit for the case I have been studying, which contained a change of part of places in the industrial hall which was built to meet the needs of wood processing industry for a new activity, the performance of car mechanical services. The facilities for the new activity needed to be adjusted by using reconstruction parts. The thesis has been divided into several chapters in which I have described the process of making the project documentation, the process of acquiring the building and later usage permit and also my personal
observations on the matter. In each chapter I have first presented the basic legal provisions, which are required for each phase of work, and then I have tried to carefully describe the documentation which has been prepared for the studied case so that the legal provisions were met. Furthermore, I have also pointed out the problems I have run into while working on the above mentioned case, especially problems I have noticed in acquiring the necessary permits from the legal state administrative body for the usage of building.
