In the thesis it is established that the system of local self-government is a set ofinteracting and interrelated parts, subsystems, elements that form a single integral social formation, which has special system integrative qualities and self-control. The components of the system of local self-government include: elements, ties, relationships, structure. The solution of issues of local importance connects all elements of local self-government into a single whole. It has been established that housing and communal services, the proper maintenance of houses and adjoining territory, provision of basic services for electricity, water, heating and wastewater are of local importance (as an ontological basis for the functioning of local self-government in Ukraine). Analysis of the functions of the condominium associations has shown that the solution of a number of issues of local importance is of their responsibility. As a result, the condominiums
solve some of the issues of local importance, and are included into the system of public authority through the institution of local self-government as a part of it.
It is revealed that public authority is a form of embodiment, implementation and protection of the interests of a particular social community. The social structure of society is hierarchical and has the communities of national, regional, and local levels. It implies the necessity of forming (at the specified levels) an appropriate structure of public governance. It is proved that within the condominium (as multi-apartment building) a community of co-owners and co-residents is formed that has its own social identity, its own common interests, it forms common entities, develops various mechanisms of self-organization, etc. Under the conditions of the development of the public governance system the necessity to form a system of domination at the level of the multi-apartment building, one of the forms of which is a condominium.
It is determined that the mechanism of the condominium functioning is based: on the combination of elements of direct and representative democracy; on the distribution of power, which is characteristic of any mechanism of public administration. General meetings and polls of residents are a factor in the development of direct democracy in the activity of condominiums, which is more intensive in this institute than in higher levels of governance (local government, public administration). The meeting of representatives is a manifestation of the representative form of democracy at the level of condominiums. The executive mechanism of the condominium is embodied, first by the board and chairman of the board, and, second by the control board and the audit committee. The common interests of several condominiums can be solved through the associations of condominiums. The institutional model of condominiums, mechanisms and tools of this model functioning, in addition, allow characterizing it as a public model by its nature.
The analysis made it possible to conclude that in the institutional mechanism of the functioning of condominiums there is a large number of forms and directions of cooperation between local governments with condominiums, which are divided into economic and noneconomic ones. The economic forms are in the financial support of the condominium associations by local self-government bodies in the capital repair of multi-apartment buildings, the provision of tax privileges and subsidies, and the involvement of condominiums in various types of financial contests. Non-economic forms include the provision of organizational, methodological, and consultative assistance to condominium associations on the part of local self-government bodies, personnel training of condominiums, delegation of powers to condominiums, involvement of condominiums' representatives into decision-making processes of local self-government bodies, etc.
