On April 1, 2015, the Housing Control Center was established in the mayor's office.

The state capital of Mainz has long been ranked among the German cities with the most expensive rents. Behind cities such as Munich, Stuttgart, and Frankfurt am Main, the capital of Rhineland-Palatinate also ranks among the top cities.

As a popular destination and city of science, Mainz is far from experiencing demographic decline. On the contrary, its population and thus the demand for housing are growing steadily.
Mainz therefore needs significantly more housing, especially affordable housing, which requires major efforts in new housing construction and an intensification of subsidized housing construction. It is important to focus on the potential areas available for housing construction in Mainz.

The city of Mainz does not build apartments on its own and is dependent on the initiatives of housing construction companies. For this reason, the state capital of Mainz founded an alliance for housing in 2015. In addition to the city-affiliated housing association, private companies, the Chamber of Industry and Commerce, the Chamber of Crafts, the state of Rhineland-Palatinate, and many other organizations have joined this alliance.

The city administration has presented the "Living in Mainz 2020" concept and will update it in due course. The concept provides a comprehensive overview of developments, projects, instruments, and perspectives for housing in our city. The concept is available for download on this page.

In 2020, the city administration published a housing market report. Further information can be found in the corresponding press release below. The press release also includes a link to download the housing market report.

In 2014, the city of Mainz introduced the Partnership-Based Provision of Building Land. This is an instrument for socially equitable land use planning. Following an amendment to the draft resolution in 2020, all planning areas with residential construction involving 10 or more residential units per plot must ensure that around one-third of the housing is subsidized through project-related or urban development contracts. Further information and the corresponding draft resolution can be found in the City of Mainz's council information system.
