Rents are regulated by the city government so that none of the residents pay any more than 20 to 25 percent of their household income for housing, compared to the corresponding 30 percent benchmark in the U.S. A unique feature of Vienna’s social housing program, Lindstrom noted, is that the city’s income restrictions for subsidized units only apply when families first move in. Residents are never required to move out, even if household income levels increase in the following years.
