The International Union of Property Owners – Union Internationale de la Propriété Immobilière (UIPI) is a pan-European non-profit association comprising of 31 organisations from 28 countries. Jointly, they represent more than 5 million private property owners of some 20 to 25 million dwellings all over Europe! Founded in 1923 in Paris, the UIPI is the leading organisation for individual owners and private landlords in Europe. The property owners represented by the UIPI, range from individual home owners, private landlords with a single bedroom flat or multiple-occupancy houses, to landlords with large property portfolios in the private-rented and commercial sectors. The UIPI also supports dispossessed property owners in former communist countries. The mission of UIPI is to protect and promote the interests, needs and concerns of homeowners and landlords at the national, European and international levels.
