What factors should govern a Building Control Authority’s inspection?


Although there is no specific guidance on what constitutes a proper, full inspection, there are a number of significant factors. The inspection should cover as many parts of the Building Regulations as is practical. Building Control Authority inspectors should inspect housing developments at various construction stages, while a full inspection may not take place of the same development.

A Preliminary Inspection Plan should consider the following:

  • Foundation stage inspection may include compliance with Parts A and C, and possibly H.

  • Inspection of DPC and radon barrier may include Part C compliance.

  • Construction stage inspection may include Part B, C, E, J and L (fire barriers, moisture penetration, sound and thermal insulation, cavities, ties, flashing etc.).

  • Inspection close to completion stage may cover compliance with Part E, F, L, K, and M (i.e. fire separation, vents, and flues).

For further information, refer to the Code of Practice for Inspecting and Certifying Buildings and Works, September 2016.
