HCA: Heritage Conservation

What the control sets

Consent is required — despite anything else in the LEP — for a list of acts on heritage land: demolishing, moving or altering a heritage item or a building, work or relic within a heritage conservation area; disturbing or excavating an archaeological site or a land containing Aboriginal objects; erecting a building on land on which a heritage item is located or within a conservation area; and subdividing that land.

Note what that list does: it catches work that would otherwise be exempt or need no approval at all. On unaffected land, repainting or replacing a fence is nobody’s business. On a heritage item it can be a development application, unless clause 5.10(3) applies: consent is not required where the owner has notified the consent authority and the consent authority has advised in writing, before any work starts, that it is satisfied the work is of a minor nature or is maintenance and would not adversely affect the heritage significance. Ask first; do not assume the exemption.

An item and a conservation area are not the same control

A heritage item is an individual place listed in Schedule 5 of the LEP and shown on the Heritage Map, with its own significance and often its own curtilage. The listing is about that place.

A heritage conservation area is a mapped area in which the clause applies to every property, listed or not. A perfectly ordinary 1970s house inside an HCA is caught, because what is being conserved is the character of the area rather than the significance of that building. Owners frequently do not know they are in one — nothing about the property is listed anywhere.

A third listing sits outside the LEP entirely: the State Heritage Register under the Heritage Act 1977. An item can be on both, and where it is on the State Heritage Register an approval under that Act is required in addition to development consent.

What the consent authority has to consider

Before granting consent the consent authority must consider the effect of the proposed development on the heritage significance of the item or area concerned. It may require a heritage management document — a heritage impact statement, or a conservation management plan for a more significant place — and it may require the development to be carried out in accordance with it.

For a feasibility, the consequences are time and design rather than a number. The heritage impact statement is a specialist report prepared before lodgement. The design is likely to be tested against setting, scale, materiality and the retention of fabric, and the outcome often constrains the form more than the mapped height and floor space ratio do. Neither of those constraints is visible in any mapped standard.

The conservation incentive is a real, and underused, provision

Clause 5.10 carries an incentive limb: consent may be granted for development on land on which a heritage item is situated even though the development would otherwise not be permitted, where the consent authority is satisfied that conserving the item is facilitated by granting consent, the proposal is in accordance with a heritage management document approved by the consent authority, the consent requires the conservation work in that document to be carried out, and the development would not adversely affect the heritage significance of the item, including its setting.

This is the clause under which an otherwise prohibited use — a commercial use in a residential zone, typically — becomes available on a listed site, on the footing that the revenue is what pays for the conservation. It is not a bonus that arrives automatically, and it is conditioned on the conservation actually being delivered, but on a site whose listing looks purely like a cost it is the provision worth reading first.

Why a heritage area or item switches complying development off

The Codes SEPP excludes complying development on land within a heritage conservation area, or a draft heritage conservation area — with narrow carve-outs for detached outbuildings, detached development other than a detached studio, and swimming pools (clause 1.19(1)(a)). Land carrying an individual heritage item is also outside the Housing Code: NSW Government material says complying development cannot be carried out on a State or locally listed heritage item. Which paragraph of clauses 1.17A to 1.19 carries that exclusion for an item is not confirmed here, so it is cited as “Codes SEPP clauses 1.18 to 1.19 (paragraph to confirm)”. Either way, treat a listed item as a development application.

The practical reading: if your land is inside an HCA, the fast pathway is off for most things and the application is a development application. Working out which of the two you have — and whether an HCA is merely draft, which counts — is a question for the planning certificate, because the distinction is exactly the one a map layer is least likely to make cleanly.

Area exclusion described from clause 1.19(1)(a) of the Codes SEPP; the item exclusion from NSW Government summaries of clause 1.19 (paragraph to confirm). Clause 5.10(3) and (10) wording as reported from the Standard Instrument text on AustLII (29 September 2026). Transcribed from the Codes SEPP, current version for 8 July 2026, read 9 September 2026 (zone applicability checked against the NSW Planning Portal Housing Code page on 29 September 2026).
