Has the introduction of the possibility to build a single-family house on the basis of notification really improved the development process? The analysis based on the example of the Capital City of Warsaw (Poland)

On 28 June 2015 an amendment of the Polish Building Code that abolished a requirement to get a building permission to construct or reconstruct a free standing one-family house, which impact area is limited to the plot on that it is planned, came into force. Since then an erection of such houses has been possible on a basis of notification instead. The goal of this amendment was to simplify the development process in the case of one-family houses. This article is a contribution to the verification of this assumption. Therefore data on notifications that were submitted to respective capital city of Warsaw districts’ offices  have been analysed. Detailed research has been limited to the districts of Bielany and Białołęka.
