All maintenance ended with the fall of communism in 1989, and the building remains closed to the public due to the hazards of the weakened structure.

[1] The Buzludzha Project has helped to begin work on the monument's preservation, with the eventual aim of creating an interpretation center for Bulgarian history.

[2] Inside the building, mosaics commemorating the history of the Bulgarian Communist Party cover approximately 937 square meters; 35 tons of cobalt glass were used in their manufacture.

[5] At the opening ceremony, Bulgarian communist leader Todor Zhivkov announced: I am honoured to be in the historical position to open the House-Monument of the Bulgarian Communist Party, built in honour of the accomplishments of Dimitar Blagoev and his associates, who 90 years ago laid the foundations for the revolutionary Marxist Party in Bulgaria.

Let the pathways leading here – to the legendary Buzludzha Peak, here in the Stara Planina where the first Marxists came to continue the work of sacred and pure love that was started by Bulgaria's socialist writers and philosophers – never fall into disrepair.

The most recent preservation works started in 2019 under the Buzludzha Project Foundation, in collaboration with ICOMOS Germany and the municipality of Stara Zagora.

[12] Early results indicated that the building could be preserved and used, leading to a second Getty grant in July 2020 to stabilize surviving mosaic panels.
