An increase in the value of real property triggers, in some circumstances, the obligation on the part of the ownership title holder or perpetual usufructuary to pay a public levy to the commune. The issues of such mutual settlements between the owner of the real property and the commune arising from a change in the value of the real property have been regulated in the Act of 27 March 2003 on Spatial Planning and Development. Those fees include, among others, the so-called zoning fee which is discussed in this article. The analysis is based on views expressed by legal scholars in their writings, applicable legal acts and jurisprudence of administrative courts in this regard. The zoning fee and the legal issues related to its determination which raise the greatest doubts will be examined.
