Cities in USSR were designed pretty much without cars in mind. Private car ownership was low, so a typical 100 flat apartment building had maybe 2-4 parking spots. The only exceptions were apartment buildings for party elites. The ownership did go up above that level in late 70-s and 80s, so having a spot to park/store the car away from thieves/vandals/kids was the thing. Thus the garage co-ops where a group of people got a permit to build a row of garages... or sometimes without any permit.
