Urban Land Policy in Frankfurt am Main at the Turn of the Twentieth Century: A Case Study of a German 'Social City'

Germany's urban land policy (kommunale Bodenpolitik) attracted the attention of foreign countries. There were also many contemporary publications about this policy in Germany because it was a precondition for city planning, which included housing and transportation policies. The aim of this paper is to clarify Frankfurt am Main's land policy at the turn of the twentieth century, especially under Franz Adickes' era. Adickes, the third senior mayor (1891-1912), carried out urban land policy as a consciously planned intervention in the land market. His land policy had two additional objectives: The first was securing land for administrative buildings and public facilities. The second was the facilitation of city extension and the preparation for future incorporation. Frankfurt's municipal land increased from 4,229.17 ha in 1900 to 6,370.19 ha in 1913. Land purchased by the city consisted of 11,649 estates during the period 1895-1915. Conversely, land sold during the same period consisted of only 2,465 estates because it was difficult to set land prices. As a result, the Erbbaurecht (Heritable Building Right) was utilized as a substitute measure for land sales. Though Frankfurt's urban land policy produced good results, it was forced to change owing to 'the predominance of purchasing policy' and increasing debt. Thus, the state government also became involved with the land and housing policies. The land policy shifted from the stage of 'social city' to that of 'social state' after World War I.
