One of the main tasks in the formation of the regional program of overhaul is its cost estimate. In other words, it is necessary to know the amount of financial resources required for its implementation, both in the short and long term. The size of the marginal cost of work of common property overhaul in the apartment building, which is presented in the regional program, contains consolidated indicators of the overhaul of individual elements (types of work) of the apartment building. They are characterized by the presence of errors in their development and the general secrecy of information about the source data and methods for obtaining them. Currently, there is no base of enlarged estimated standards for overhaul, which are developed for objects-analogues. These standards will allow to quickly determine the preliminary cost of the common property overhaul of the apartment building at the stage of implementing tenders, in order to optimize the amount of necessary and sufficient investments.
