SA NSW development guidelines

All development in a mine subsidence district (district) must be constructed in accordance with Subsidence Advisory NSW (SA NSW) approval.

SA NSW has set development guidelines to help landowners building within a mine subsidence district. The guidelines set out the requirements for building on a property based on potential subsidence risks.

SA NSW’s guidelines include requirements related to the nature and class of any development on a property, the size, height and location of new structures, and the use of certain building materials and construction methods.

Neighbouring properties in a district may have different guidelines. This is because SA NSW individually considers the subsidence risks on each property when determining the appropriate guideline. This may occur when one property is mined beneath while the neighbouring is not.

Find the SA NSW development guideline for properties in mine subsidence districts via the NSW Planning Portal
