In this project, the subject of building lease is being discussed as seen on the example of the City of Rijeka. It is an institution defined by the Law of ownership and other legal matters. Apart from the conceptual definitions, this law also arranges the content of the building rights, acquiring building rights, its conservation, termination and its consequences. Persons who bear the building lease and set it up are mentioned in this elaboration as well. Through this work, there are numerous examples in which the role of the founder holds the City of Rijeka itself. Rijeka owns land of great proportions suitable for establishing this institute. Furthermore, this project shows the definition of building lease as “a limited law of real property on somebody's land which entitles its owner to own a building on the area of that land or beneath it. While explaining the content of the institute in question, the example of Rijeka Promet Ltd was taken into attention. Inevitable subjects were the functions of the building rights, and the building of the residential facilities for strictly social purposes which played a main role in the 21st century. To continue with, there is a detailed look into the building rights with an interesting example of an underground garage “Stari grad” which is located on the property owned by the City of Rijeka. The land property has been defined and there are cases of building under ground as well as on the surface. About acquiring building permits, all facts according to the are pointed out. The subject has further been divided by covering the topic of titulus and modus way of acquiring rights. To show how that works, there is a practical example of the former Rikard Benčić which to this day hasn't been carried out, and the examples of the contract between the City of Rijeka and the Croatian Electrical Company “HEP” and the example of the University of Rijeka. To sum up, the subject of building termination and its consequences were mentioned. Termination often happens in practice due to the high fees which come up while trying to establish the building lease, which then cannot be paid for. Nowadays, when the financial situation is getting worse and worse, the bearers of the building lease do not fulfil their legal contract duties and therefore termination is bound the happen and the projects finish unrealized, which is shown on the example of the Kantrida stadium and camp Rujevica.
