There are many indications that it does not. The legal system currently in force is the judgment II SA/Gd 329/14 issued by the Voivodship Administrative Court in Gdańsk
In the justification of the appeal judgment in this case (i.e. the building permit in the context of a mast on a building), the Court referred to the content of art. 29 sec. 2 item 15 of the Building Law, as well as art. 30 sec. 2, 6 and 7 of this Act. According to the content of these provisions, a building permit is not required for the performance of construction works consisting in the installation of devices, including antenna support structures and radio communication installations, on buildings. The performance of such works is subject to notification to the competent authority. The notification should specify the type, scope and method of performing the construction works and the date of their commencement. The notification should be accompanied by the declaration referred to in art. 32 sec. 4 item 2 and, depending on the needs, appropriate sketches or drawings, as well as permits, agreements and opinions required by separate regulations. The notification should be made before the date of the intended commencement of construction works. The construction works may be commenced if, within 30 days from the date of delivery of the notification, the competent authority does not raise an objection, by way of a decision, and no later than after 2 years from the date of commencement specified in the notification. The competent authority raises an objection, in particular, if: the notification concerns the construction or performance of construction works covered by the obligation to obtain a building permit. In addition, the authority referred to the regulation of the Minister of Infrastructure of 26 October 2005 on the technical conditions to be met by telecommunications construction facilities and their location (Journal of Laws No. 219, item 1864, as amended). Referring the above regulations to the legal status, the authority stated that, for example, the investor's intention to perform construction works consisting in the construction of an antenna support structure together with a base fastening to the structure of the existing construction facility and guy wires and antennas mounted to it together with radiocommunication installations is subject to notification, which structure constitutes a device within the meaning of art. 29 sec. 2 item 15 of the Building Law.
