According to the Law on Real Estate Registration, in order to register a new building in the building register, it is necessary to attach an "Elaboration for the registration of the building in the building register", which is prepared by a surveying company or a designer. The elaboration of the elaboration costs about 500 EUR. Given that the data are identical to those in the project documentation of the building permit, it would be reasonable to automatically take them into account for the elaboration as well, rather than having to pay again for the already known data.
