On January 3, 2022, the Act of September 17, 2021 (Journal of Laws 2021.1986) amending the Construction Law and the Act on Planning and Spatial Development came into force. This Act introduced modifications in determining building conditions and the location of public purpose investments. Among other changes, an amendment was made to Article 61 of the Act of March 27, 2003, on Planning and Spatial Development by adding section 5a. This led to uncertainties regarding the practical administrative interpretation of the term „front of the area”, which width determines the size of the designated analysis area of the function and features of the development and land use. This issue – still relevant (since although the legislator has passed another amendment to Article 61, it will not come into force until January 1, 2026) – will be addressed in this paper.
