In the submitted paper, the topicality of the building stock in municipalities in Baden-Württemberg, part of the Federal Republic of Germany, is examined. Three municipalities were selected and included in the study according to the spatial type concept of the Federal Office for Building and Regional Planning (BBSR 2023): rural town 2,000-5,000 inhabitants, small town 5,000-20,000 inhabitants, medium-sized town, 20,000-100,000 inhabitants. The analysis concept is explained and the quantitative and qualitative results of the project, which is currently in its final phase, are presented. The aim is to use these results to derive and communicate recommendations for action for the municipalities, but also for the public surveying administration, in order to contribute to timely and effective action by municipal decision-makers and citizens through faster provision of geospatial data.
