Material change of use - hotels, institutions, places of assembly, shops
Buildings undergoing material change of use to hotels, boarding houses, institutions, places of assembly, recreation or shops must be treated as new buildings or parts must be independently accessible with accessible sanitary accommodation.
When a building undergoes a material change of use so that it is used as a hotel or boarding house, an institution, a place of assembly or recreation, or a shop it should be treated in the same manner as a new building.
When a part of a building undergoes a material change of use so that it is used as a hotel or boarding house, an institution, a place of assembly or recreation, or a shop it should –
(a) be independently approached and entered or have suitable access provided through the building; and
(b) have any sanitary accommodation that is provided for or in connection with that part accessible (from that part) and usable. If sanitary accommodation is not provided as part of any works in relation to the material change of use and if users of that part of the building have use of sanitary accommodation elsewhere in the building then people should be able to gain access to, and use that sanitary accommodation.
