The article presents considerations on the importance of the provisions of the municipality's general plan referred to in the Act of March 27, 2023 on Spatial Planning and Development, as well as the importance of the provisions of the local general plan, referred to in the Act of July 12, 1984 on Spatial Planning when estimating real estate for the purposes of determining the amount of compensation and fees referred to in Art. 36 section 3 and 4 of the Act on Spatial Planning and Development. Due to the fact that the Act of 1984 refers to the general spatial development plan of settlement units (called the general plan), prepared and adopted on the basis of the Act of January 31, 1961 with the same name, the article also discusses this type of plan. Moreover, activities related to determining the value of real estate were indicated, including the above-mentioned planning purposes, and the understanding of concepts such as "real estate data" and "intended use in the local plan" were presented. Attention was also focused on the essence of the above-mentioned types of plans, as well as the differences between the general plan of the commune and the local general plan and general spatial development plan of settlement units.
