Exempt Building Works

There are a number of buildings and building works that are exempt or partly exempt from the building regulations. This is because the buildings or works are controlled by other laws or are not regularly used by people. Examples include:

  • Buildings subject to a licence granted under the Manufacture and Storage of Explosives Regulations 2005.
  • Buildings (other than a building containing a dwelling or a building used for office or canteen accommodation) erected on a site that is subject to a license in force, issued under Nuclear Installations Act 1965.
  • A building included in the schedule of monuments maintained under section 1 of the Ancient Monuments and Archaeological Areas Act 1979.
  • Detached buildings not regularly used by people except for the purpose of inspecting or maintaining a fixed plant or machinery. This will not apply if the building is less than one and a half times its height from a point of another building people normally go to or the nearest point of the curtilage boundary of the building.
  • Greenhouses (provided they are not used for packaging, retailing or exhibiting) and agricultural buildings, provided they have fire exits not more than 30m from any point in the building, and that no part will be used for dwelling accommodation or would be less than one and half times its height from any other building that contains sleeping accommodation.
  • Temporary buildings not meant to remain after 28 days from when it was set up, for example a marquee set up for a show or exhibition.
  • Small detached buildings, these include buildings of single story without sleeping accommodation, with floor areas of less than 30m² and no point of which is less than 1m from the boundary of its curtilage or which is substantially constructed with non-combustible materials. It also covers nuclear and chemical shelters and buildings without sleeping quarters with floor areas of less than 30m².
  • Extensions at ground level, depending on their size, these may include conservatories and porches with floor areas not exceeding 30m², provided that the glazing of the conservatory or porch satisfies the requirements of Part N of Schedule.
  • Ancillary buildings. These include buildings used only for the purposes of the disposal of other buildings or building plots on the site, for example a shed on a construction site. Also, buildings on a civil engineering site set up solely for site work and without sleeping quarters, for example a temporary office unit and buildings on a mining or quarry site.

Remember, you may still require planning permission, even if your buildings works are exempt from the building regulations requirements.
