Express planning permission is required for the carrying out of building, engineering, mining, or other operations in, on, over, or under land, or the making of any material change in the use of any buildings or other land unless it does not fall within the ‘meaning of development’ in the Town and Country Planning (Scotland) Act 1997, as amended, or it is ‘permitted development’.
The change in the use of land or buildings is development and therefore requires planning permission in most circumstances. What amounts to a material change in the use of the land depends on the circumstances of each case.
Some individual uses which are similar are grouped into separate classes by the use classes order 1997. Where a building or land is used for a purpose which is included in a particular class, the use of that building or land for any other purpose in the same class, shall not be taken to involve development and therefore it would not require planning permission. In certain circumstances, this is subject to conditions.
Changes are also permitted by the General Permitted Development Order 1992, which provides that certain changes of use, though involving development, are nonetheless permitted and therefore no planning permission is required.
