CA32650 - IBA: Other rules about buildings: Parts of buildings

CAA01/S571

A building may be used for different activities, some of which would make it an industrial building and some of which would not. If different parts of the building are used for different activities you should look at each part separately in deciding whether IBA is due. The legislation lets you do this because it treats part of a building as a building.

If there is mixed use, that is if all parts of the building are used for all the activities IBA is given on the whole building provided that the activities that would make it an industrial building are not negligible CA32315.
