Change of use

Where a material change of use occurs a Building Regulations application should be made. These are where:

• the building is used as a dwelling, hotel, boarding house, institution or public building where previously it was not
  
• the building contains a flat where previously it did not
  
• the building was previously exempt and will not be after the change
  
• a building containing at least one dwelling is converted to provide a greater or lesser number of dwellings than it did previously (the term dwelling includes a flat)
