Are there any legal restrictions on the designated use to which any new building may be put or on any change in the designated use of an existing building?
The structural plans, zoning maps and local building codes may specify the different designated functions for which a new building may be built in a given zoning block.
Generally, the change in the designated use of an existing building does not require a permit, however a building permit may be required if construction works are implemented in connection with a change in the designated use. Nevertheless, in case of change in the designated use of an existing building, the municipality shall carry out a town planning notification procedure.1
If a building permit is required the building authority will decline to issue a building permit in case the intended new use is not allowed for in the local structural plan, zoning map and local building code applicable to the given zoning block.
As an exception, a permit is required for the change in the designated use of certain retail buildings and units with a gross floor area of over 400 square meters if the designated use of the given building or unit is intended to be changed into commercial function. Some other exceptions are also defined by law whereby a specific permit is required to be issued. In these cases, special licensing procedure applies (where the consent of additional authorities may also be required).2
