What legislation covers Building Control?

The present system of Building Control operating throughout the Isle of Man is based on the Building Control Act 1991, supported by the Building Regulations 2003. A copy of these Regulations is available to view or download at the bottom of this page. Generally, the regulations apply to the construction of new buildings and alterations and extensions. Changes of use are also controlled under the regulations where change involves the provision of sleeping accommodation or the provision of a public building.

Certain small buildings and extensions are exempt from Building Control. Exempt Buildings. For comprehensive advice on exemptions and what requires Building Regulations approval, contact the Department’s Building Control Section, or the 3 other Building Authorities on the Isle of Man.

health and safety for persons in or about buildings (and any others who may be affected by buildings, or matters connected with buildings);
energy conservation;
access and facilities for people with disabilities; and

What building work is controlled by the Regulations?

is used as a dwelling, where previously it was not;
contains a flat, where previously it did not;
is used as a hotel or boarding house, where previously it was not;
is used as an institution, where previously it was not;
is used as a public building where previously it was not;
is used as a an industrial premises, where previously it was not;

is not a building described in classes 1 to 5 in Schedule 2, where previously it was; and
is not an 'exempt building' where previously it was.

When a material change of use takes place, the building, or affected part, needs to be upgraded to satisfy certain important parts of the Regulations. Fire safety, ventilation provision and energy conservation applies to all the cases above. Structure, weather resistance, fire spread and sound insulation apply in specific cases.
