s 53 Transitional provisions
53.—(1) Any licence, permission, approval or other document prepared, made or granted under the repealed Act and valid immediately prior to 1 May 1989 is deemed to have been prepared, made or granted under the corresponding provision of this Act. (2) A valid and subsisting certificate of fitness for occupation issued under regulations made under the repealed Act or a valid and subsisting temporary occupation licence has the same force and effect as a certificate of statutory completion or temporary occupation permit, respectively, granted under this Act. (3) Any temporary permit, permission or other similar document issued in respect of a temporary building under any written law relating to building control in force before 1 February 1960 is presumed, until the contrary is proved, to have lapsed or expired. (4) The powers conferred on the Commissioner of Building Control by this Act may be exercised in respect of —(a) any building erected in contravention of, or deemed to be unauthorised under, any written law relating to building control in force before 1 May 1989; and (b) any temporary building in respect of which no temporary permit, permission or other similar document issued under any such written law relating to building control or this Act is in force, and such building is deemed unauthorised for the purposes of this Act. (5) Where any written law or document refers expressly or by implication to a temporary occupation licence or to a certificate of fitness for occupation, the reference is (except where the context otherwise requires) to be construed as a reference to a temporary occupation permit or a certificate of statutory completion, respectively. (6) In this section, “temporary building” means a building which is required for a limited time or constructed of short‑lived materials.
