Parallel to his academic career, Viehweger became active in local politics.[1][2][3] From 1979 to 1985, he was a member of the District Assembly of Dresden-West. From 1981 to 1985, he additionally was chairman of the Dresden-West LDPD and from 1986 to 1990, chairman of the Dresden LDPD.[1][2]
In 1985, he was made full-time city councilor (member of the municipal government) for energy of Dresden, a position he held until 1990.[1][2][3] He later described his work there as "Saving electricity, distributing coal".[3]
de Maizière Government
After the Wende, the LDP, its new name after being renamed in February 1990,[2][3] joined forces with the other liberal parties in the GDR to form the Association of Free Democrats (BFD). Viehweger became a member of the executive committee of the BFD.[1][2]
From April to September 1990, Viehweger served as the last Minister for Construction, Urban Development and Housing in the cabinet of Lothar de Maizière.[1][2][3][4][5][6] Despite the BFD leaving the government coalition in July 1990, Viehweger remained minister.[2]
As Minister, Viehweger was mainly tasked with renovating the crumbling cities[3] and introducing market economy principles in this sector, including liberalizing the construction industry and creating a free housing market.[7] Of the approximately 4,500 employees, almost 90% were laid off or outsourced to other institutions.[4][7] The numerous research institutes assigned to the ministry, such as the GDR Construction Academy, were either be dissolved or transferred to other legal entities by 3 October 1990. The housing construction combines, which were also under the responsibility of the ministry, were taken over by the Treuhandanstalt.[4][7]
He resigned from his position on 28 September 1990, following the disclosure of allegations of now disproven[2] collaboration with the Stasi under the pseudonym "Jens Grabowski,"[8] as well as the recommendation for immediate resignation.[1][2][3][9] As a city councilor in Dresden, he is said to have maintained contacts with the Stasi. Viehweger admitted this, but denied having signed an IM declaration and passing on documents.[3][9]
During the first legislative period, he was a member of the Saxon State Parliament from 1990, elected from the state list of the FDP.[1][2] According to a report in the Sächsische Zeitung on 13 November 1990, Viehweger was on leave from his parliamentary mandate until March 1991[2] "at the request of the FDP parliamentary group and after a conversation with the FDP federal chairmanGraf Lambsdorff" until the Stasi allegations against him were clarified.[10]
On 4 November 1991, Viehweger was expelled from the parliamentary group. Subsequently, he resigned from the FDP and remained a member of the state parliament as an independent member for the rest of the legislative period ending in 1994.[2][3][11]
Already during the legislative period, Viehweger began working in various positions in the housing industry. From 2000 to 2002 he was head of the Central and Eastern Europe working group of CECODHAS (Association of the European Social Housing Industry). From 1 January 2002 to 31 December 2019, Viehweger was director and board member of the Association of Saxon Housing Cooperatives.[1][2][3]
