Northern Territory Consolidated Acts(1) The owner of land to which a development permit relates, or a person authorised by the owner, may at any time before the permit lapses apply to the consent authority for a variation of a condition of the permit.
(2) The application must be in the approved form and accompanied by the prescribed fee.
(3) The consent authority may, in writing, vary a condition of a development permit if:
(a) the proposed variation will not alter a measurable aspect of the development by a margin greater than 5% and, in the opinion of the consent authority, will not materially affect the amenity of adjoining or nearby land or premises; or
(b) in the opinion of the consent authority, the alteration resulting from the proposed variation is not conveniently measurable and the proposed variation will not materially affect the amenity of adjoining or nearby land or premises.
(4) Despite subsection (3)(a), a permit must not be varied if it will allow an increase in the number of dwellings capable of separate occupancy.
(5) If the consent authority refuses to vary a condition of a permit in accordance with an application, the consent authority must give to the applicant a statement of the consent authority's reasons for the refusal.
