According to art. 1251 of the Civil Code of the Republic of Moldova, by means of the lease agreement, one party commits to give the other party an individually determined asset for temporary use or temporary use and possession, and this obliges him to pay rent. This work represents interference between public and private law that brings to the foreground-present theme - the real estate owned by the administrative-territorial unit and their management. We set out to bring a more in-depth feature of real estate property with non-rentable status, which is the object of the lease of non-rentable rooms owned by the Chisinau Municipal Council. The general conclusion of the study is that, in the segment discussed, Chisinau Municipal Council is not a good owner, because it is not able to properly manage its assets, and this leads to economic, but also social losses.
