30When building approvals not to be issued—general

30 When building approvals not to be issued—general (1) A certifier must not issue a building approval if carrying out the site work to which the application for the approval relates would result in the contravention of this Act or any other law in force in the ACT because of— (a) the design or siting of a proposed building or a building as proposed to be altered; or (b) the material used in the building; or (c) the proposed use of the building as determined by the class of building; or (d) the number of buildings on the land. Under the Planning Act 2023, s 276 leased land must not be used for a purpose other than a purpose authorised by the lease. A lease provides that the leased land may be used only for a single dwelling. If an application for building work on the land contains plans for 2 dwellings in a single building, carrying out the site work will result in a contravention of the lease and therefore the Planning Act 2023. Accordingly, a certifier must not issue the building approval. If an application for building work on the land indicates that 1 room is to be used for a home office, and part of the lounge room is to contain a bar area, the building may still be used as a dwelling and a certifier could issue building approval, even though conducting a home business may require development approval.
