This page outlines all works and buildings that are exempt by Regulation 9 and Schedule 2 of The Building Regulations.
Building regulation exemptions
Not all buildings and extensions are subject to control under The Building Regulations, Regulation 9 exempts buildings and work of a kind described in Schedule 2 of The Building Regulations.
The carrying out work to or in connection with a building or extension described in Schedule 2, will also be exempt from the requirements of The Building Regulations, providing that after carrying out the work the building or extension still fits the relevant criteria of Schedule 2.
For example, an existing exempt garage with a floor area of 20 square metres is to be extended by a further 5 square metres. The cumulative floor area of the existing and proposed are still within the 30 square metre limit, the proposed extension is therefore exempt.
