Commentary on Sections Glossary History Section 283: Non-industrial part of building disregarded
989.This section is based on section 18(7) of CAA 1990. It is a de minimis rule. Its effect is that allowances are given on all the qualifying expenditure if 25% or less relates to a part of the building which would not otherwise qualify.
990.Subsection (1) refers to section 571. That provides that references to a building include references to part of a building. So parts of a building which are used differently need to be looked at separately to see if they are industrial buildings. Subsection (2) gives the de minimis rule.
