In practice this is accomplished by non-profit private housing foundations or associations (). Due to frequent mergers the number of these organizations dropped to around 430 by 2009. They manage 2.4 million dwellings. The majority of the low-rent apartments in the Netherlands are owned by such organisations. Since the policy changed in 1995 the social housing organizations have become financially independent, focusing on their role as social entrepreneurs. In most Dutch municipalities there came to exist a certain minimum capacity of social housing throughout the last decades. In many cities such as Amsterdam, The Hague, Rotterdam and Utrecht the percentage of social housing approaches or even passes 50 percent. The public (financial) supervision is done by the central fund for housing ().
