Lenin cathegorised people belonging to other class but also needing to sell their labour to live as “half-proletarian”. Usually he meant peasants having too little land to live from, but i think it can be also used for this kind of small time renters.

They key to that was that such situation is usually not stable, capitalism eventually will shove those people to become fully wage labourers, similar to the petit bourgeoisie and small scale landowners.
