Owners of historic buildings whose technical condition is unsatisfactory must make a decision about their future. These buildings were built at a time when requirements regarding their functionality were different than today. In order for them to be used, they must be renovated, and the elements that have undergone degradation must be restored. This process is often accompanied by a change in the utility function that allows the building to be used in the current economic realities. This paper presents a methodology for the decision-making process regarding the scope of renovation and reconstruction works on historic buildings, taking into account their new utility program. An example of the renovation of a two-story post-industrial building located in Częstochowa was presented, for which its previous utility function was changed. When adapting the building to new operational requirements, the assumption was made to preserve the existing substance of the building to the greatest extent possible while meeting all structural conditions. It was assumed that most of the visible architectural and construction elements referring to the original character of the building would be restored. The scope and justification for performing individual renovation and reconstruction works are discussed. It has been shown that the applied methodology allows for rational adaptation of the building to current operational requirements while maintaining its original, historic character to the greatest extent possible.
