London Building Acts (Amendment) Act 1939 applications

Applications under this Act may need to be submitted for certain types of work. These applications are usually required in addition to the normal Building Regulation application. The relevant sections of the Act are listed below.

Fire Safety in Large Buildings (Section 20)

Section 20 and 21 repealed

Section 20 and 21 were residual parts of the London Building Acts (Amendment) Act 1939. Section 20 dealt with fire safety in tall or large cube buildings and Section 21 with the uniting of buildings. Sections 20 and 21 were repealed by The Building (Repeal of Provisions of Local Acts) Regulations 2012 with effect from 9 January 2013.

The effect of this repeal is that applications for consent are no longer necessary and that any conditions imposed in previous consents cease to have effect from 9 January 2013.

If you intend to remove fire safety provisions that were installed into a building because of its Section 20 or Section 21 status, it is advisable to discuss the proposed removal with the local fire authority, as there may be implications under the Regulatory Reform Order.

Section 30

Section 30 applications are used when the erection or retention of certain temporary buildings and structures that are not covered by the Building Regulations 2010. Examples include a marquee, flag pole, flue pipes, freestanding boundary walls greater than 1.83 metres high among others.
