The restructuring of the State Forests National Forest Holding activity also covered the functioning of the existing forest building infrastructure in the forest district administrations. In the paper I present the issues and specificity of forest building engineering, as well as problems connected with the sales of buildings offered by the State Forests National Forest Holding in 1999-2008. To illustrate the process of selling buildings in RDSF, an analysis of real estates foreseen for sale and listed in the "Information Bulletin of State Forests" in 1999 to 2008 was carried out. The buildings were divided into nine groups taking into consideration the type of building and the management method specified in the notice of sale. The differentiation in the functioning of forest building infrastructure was depicted in the research carried out in a number of forest districts in the Forest Utilization Department. In the author's opinion the main problems to be solved are connected with the rational use of the buildings.
