Protection of Adjoining Properties
Protection of Adjoining Properties

During the checking of an ‘Application for a Building Permit’ the Relevant Building Surveyor may determine the need for ‘Protection of Adjoining Properties’.

When it is determined by the Relevant Building Surveyor that ‘Protection of Adjoining Property’ is required; this process, as outlined in the Building Act 1993, must be completed prior to the commencement of any building work that relates to the works that warrant protection measures.
