The thesis presents the housing legislation in Slovenia since 1991. Positive and negative sides of home ownership and home renting are described. The rent for non-profit housing is formed according to the law following a valid methodology, while the rent for commercial housing is formed freely. The thesis contains an analysis of apartment rental market in 2014 based on signed lease agreements. A detailed analysis has been made on rent prices, the volume of renting and characteristics of the rental apartments within Slovenian municipalities. Analysis of rented apartments were performed also by city zones of each city municipality, which were created especially for this assignment and derive from zones of mass real estate appraisal models. The rent analysis showed that most of apartments were rented in city municipality of Ljubljana where the rent prices were also the highest. Presence of a university in a city municipality also influences the number of rented apartments. There have been many more lease contracts signed there, as opposed to municipalities with no university. In individual city municipalities the rents are the highest in city centre areas. It has been found that in some city municipalities the zones of mass real estate appraisal models are appropriate for analysing apartment prices and rents, while in other locations, such as city municipality of Maribor, those models are not usable. A t-test was carries out in order to determine whether the average apartment rents per unit in individual city municipalities and inside their zones characteristically differ from each other or not. The results showed a significant statistical difference among average apartment rents per unit in majority of city municipalities observed, a conclusion we cannot make for average rents between different zones of a certain city municipality.
