At the beginning of the 1990’s, post-Soviet Russia began an accelerated political, economic, and social «transition». The housing system, socialized with the October Revolution, was privatized. This paper examines the housing constructed during the Stalinist period (from the 1930’s - 1950’s) in St. Petersburg. This segment of the housing system boasts particular characteristics: the architectural and technical quality of the buildings, functional neighborhood layout, and the social homogeneity of the inhabitants. These characteristics also constitute factors of improvement in the Stalinist segment of the post-communist period. Political changes that concern Russia during the first years of the 1990’s transformed urban space, but did not compensate for the inequality inherited by the socialist regime. From this point of view, Stalin’s housing system constituted a significant legacy.
