If building works works have been undertaken without the necessary building control consent, a regularisation applicaition can be submitted for these works providing they were commenced on or after 11 November 1985. The application should include plans of the unauthorised work and plans showing any additional work required to comply with the regulations. It may be necessary to uncover certain elements of construction in order to ascertain compliance with the relevant regulations. Once all necessary works have been undertaken a regularisation certificate will be issued. The submission of a regularisation application does not preclude us using our powers under Section 35 Building Act 1984.
