Hot water and solar energy systems

Hot water systems

Constructing or installing a hot water heater or hot water storage tank may not need planning approval (known as exempt development) if the proposal meets the relevant development standards identified in the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 (the State Policy).

The following additional standards apply specifically to hot water systems:

  • If the system is installed externally and on or in a heritage item, draft heritage item, heritage conservation area or draft heritage conservation area, it must:
    • not be located on a roof
    • be in the rear yard.

Please refer to these provisions in the State Policy in the State Policy for development standards relating to hot water, systems, including noise level requirements under exempt development.

Solar energy systems

Solar energy systems may be installed as exempt or complying development under the State Environmental Planning Policy (Infrastructure) 2009 (the ISEPP).

A solar energy system means any of the following systems:

(a)  photovoltaic electricity generating system

(b)  solar hot water system

(c)  solar air heating system.

Other considerations

  • If you propose to remove or prune any existing trees or vegetation, you should contact your council first to make sure you don’t need approval for this.
  • Works must be structurally adequate, installed in accordance with manufacturer’s specifications and comply with the Building Code of Australia (BCA).
  • Any structures that would be located on public land, or on or over a public road (including temporary structures), must have separate approval from the relevant council, or Roads and Maritime Services under the Roads Act 1993 and the Local Government Act 1993.
  • Generally, exempt development cannot be carried out on:
