Housing precarity is a condition of instability and vulnerability in the housing sphere, which can manifest in various forms and affect people regardless of income level or social status. It encompasses situations in which housing is not safe, of adequate quality, or accessible in the long term, which are necessary for a full and secure life. This article analyzes housing precarity as a multidimensional socio-economic phenomenon influencing various aspects of people’s lives. Housing precarity is considered in the context of international research, with an emphasis on the fact that precarious living conditions go far beyond mere housing provision and encompass a wide range of issues: legal vulnerability, threat of eviction, overcrowding, poor housing quality, and limited access to infrastructure and social services. The article discusses various classifications and concepts (“precarious ownership,” “recursive precarity,” “hidden homelessness,” etc.), as well as the forms and dimensions of housing precarity (time, space, etc.). It is shown that precarities in different domains—housing, labor, legal—can intersect, mutually reinforcing and consolidating each other. The role of cohabitation practices and the “home culture of precarity” in the transformation of millennial everyday life is also highlighted. Special attention is given to socio-demographic groups most vulnerable to housing precarity and to the housing strategies they adopt to mitigate its effects. The conclusion emphasizes the need for a comprehensive approach combining housing, social, and economic policies to ensure housing security and reduce social vulnerability.
