The Netherlands have a very specific housing tradition, in which the government and the municipalities play a major role. Ever since the passing of the Dutch Housing Law in 1901, affordable dwellings for all inhabitants of the Netherlands have been a national priority. Today, more than 30% of the housing stock belong to the social rental sector, and 29,3% of all houses are owned by corporations.
In the big cities in the West, however, the system is under pressure due to the economic boom. While Rotterdam is trying to introduce more high-quality dwellings, Amsterdam attempts to guarantee that residential projects remain affordable for middle income groups. The municipality has issued the rule that all new residential projects should contain 40% social, 40% mid-range and 20% up-market dwellings. Regulations of this type are possible because 80% of the ground is owned by the municipality.
