If your proposal meets all the relevant criteria for exempt development set out in the relevant planning instruments, then consent is not required. This is a self-assessment, and it is up to the person carrying out the works to ensure the relevant criteria are met.
Consent is generally required for developments or works to be carried out on heritage items or within heritage conservation areas. If you are unsure if your property is listed as a heritage item or within a heritage conservation area, you can check using the Department of Planning's free Spatial Viewer, or contact one of our duty planners for further clarification.
A proposed development will only be considered exempt if it satisfies all of the relevant criteria.
Further clarification on what may be categorised as exempt development in NSW is available on the Department of Planning's website here.
