The Building Regulations set out the minimum legal requirements that apply when a new building is being constructed or when an existing building is being extended or undergoes a material alteration or a material change of use. Part B of the regulations addresses fire safety and the accompanying Technical Guidance Document B (TGD B) outlines how the legal requirements may be achieved in practice. Where works are carried out in accordance with TGD B, this will, prima facie, indicate compliance with Part B of the second schedule to the Building Regulations. Alternative approaches to that outlined in TGD B are permitted but in such circumstances the onus is on those availing of the alternative approach to establish that it complies with the requirements of Part B of the Building Regulations. A full review of Part B/TGD B is currently being undertaken by my Department and I anticipate that detailed proposals will be brought forward for public consultation by the end of the current year.
