The citizens' petition against the development of the A2 section of Stuttgart Rosenstein did not reach the necessary quorum of 20,000 valid signatures. The municipal council of the state capital Stuttgart therefore declared it inadmissible on December 4, 2025.
Lord Mayor Dr. Frank NopperThe failure of the citizens' petition shows that the people of Stuttgart want to seize the opportunity of the century in the Rosenstein Quarter and thus the chance of a future quarter with thousands of apartments in the immediate vicinity of the city center.
Quorum of 20,000 not reached
At the end of the three-month collection period on October 15, 2025, 18,270 valid signatures had been submitted. A total of 21,827 unverified signatures had been submitted by the citizens' initiative. To check their validity, all signatures were individually compared with the residents' register. Even including subsequently submitted lists, the initiative only achieved a total of 19,835 valid signatures - and thus fell short of the statutory quorum of 20,000. This means that the different assessment of the deadline by the city administration and the citizens' initiative is irrelevant.
At around 16 percent, the proportion of invalid signatures was within the usual range of between 10 and 20 percent. The main reasons for this were lack of eligibility to vote (1,100), duplicate signatures (926) and lack of residence or registration in Stuttgart (925).
Development planning is progressing
The development plan procedure for sub-area A2 will continue as planned. The Europaquartier with around 1,380 to 1,670 apartments is to be built on the area between the main railway station and Wolframstrasse once Stuttgart 21 is commissioned. At least half of these are to be subsidized. The area is part of the Stuttgart Rosenstein urban development project, which will create living space for around 10,000 people. Nopper emphasizes: "We can now push ahead with the future-oriented Rosenstein project with all our strength and momentum - in the interests of many people looking for housing and in the interests of an attractive urban design."
