A building consent is not required to demolish a detached building up to 3 storeys high.
This exemption allows for the full demolition of all detached buildings that are not more than three storeys high. However, partial demolition is not exempt from building consent, other than as permitted by exemption 31 (section 1.4). If you are considering demolishing an existing building under this exemption, we recommend that you also consider the following:
- contacting the relevant service authorities to advise them of the extent of your work and discuss requirements regarding the termination of existing services such as electricity, gas, drainage, water, transport, telecommunications, cable television and any other services that may be affected
- handling and disposing of hazardous building materials
- controlling silt runoff, excess noise and dust generated by the demolition work, and
- securing the site (eg with a temporary fence or hoardings) to restrict public access to the area and avoid injury to members of the public.
As a building owner, you should also check council requirements for the repair and reinstatement of any damage to the road reserve.
We recommend that you use skilled and professional building practitioners for major demolition work.
No demolition work should be undertaken on heritage or character buildings without first checking with your local council for its approval.
