A retaining wall is a structure erected to support excavated or filled earth on a property.
The installation of a retaining wall is the responsibility of the landowner that has excavated or filled their land.
Adjoining landowners may become involved when the retaining wall is located on the common boundary of both properties and/or the wall is for the benefit of both properties. In the case of a common retaining wall, the two adjoining landowners must agree on any proportionate costs. Council cannot act as a mediator in relation to costs.
The installation of some retaining walls can be classified as ‘Exempt Development’, which does not necessitate development consent, as long as there is minimal environmental impacts and the installation meets the specific development standards as outlined in the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008.
Should the installation exceed any of the listed development standards. Development consent will need to be obtained prior to installation.
Development consent may be sought via Complying Development for the installation of retaining wall, provided it meets the development standards as outlined in the NSW Complying Development Housing Alterations Code.
If the proposal does not qualify as complying development, you will need to lodge a development application.
Lodgement method and details can be found on our website, at Lodging an Application.
Development consent can be sought through a development application for the installation of a retaining wall, provided the proposal meets the relevant planning controls.
Planning controls for development can be found in the Newcastle Local Environmental Plan 2012 (LEP) and current Newcastle Development Control Plan (DCP)
Lodgement method and details can be found on our website, at Lodging an application.
