When the soviets were in power they would force multiple families under one roof (kommunalka). Think 4-8 families sharing a kitchen and a bathroom. Each family was given just one room and all housing was considered communal housing en.wikipedia.org/wiki/Communal_apartment?wprov=sf…
After Stalin’s death families began receiving single family apartments due to massive housing reform by Kruschev, but were hastily built and called ‘khrushchyoba,’ a cross between Khrushchev’s name and the Russian term for slums. That by the way still leaves a multigenerational period from 1917-1954 where the kommunalka would have been the primary unit of housing.
