In case of a building permit request concerning a commercial building, an expert opinion of the appointed Government Office (Government Office of Hajdú-Bihar County) must be obtained if the request is for (i) construction of commercial buildings with larger than 400 sqm gross surface or (ii) transformation of commercial buildings with larger than 400 sqm gross surface; and (iii) enlargement of commercial buildings to exceed 400 sqm gross area. Before issuing its opinion the Government Office obtains the opinion of the committee of representatives of the minister and the minister in charge of trade and commerce, regional development and planning, environmental protection and transportation. If the Government Office does not support the building permit request, then it will be rejected by the building authority
