Questions & Answers

Do older developments set a precedent for my application?

An older development nearby can be useful as an example, but it does not give you an automatic right to build the same thing.

The neighbouring development may have been approved under different planning rules, or its block may have different zoning, Crown lease provisions, dimensions, easements, access arrangements or other site constraints.

ACT Planning assesses a DA based on the requirements applying to the particular development and considers matters such as site suitability, impacts and how the proposal interacts with surrounding and adjacent development.

For example, an older dual occupancy in your street might have been approved under planning controls that have since changed. Its existence can provide useful context for the character of the area, but your proposal still needs to satisfy the planning framework applicable to your application.

Our planning team can review nearby approvals alongside the current requirements for your property to identify which aspects may still be relevant and what can realistically be achieved on your block.

Short Answer

No. Older developments do not automatically set a precedent that guarantees the same development can be approved on your property. Your DA will be assessed against the planning requirements that apply to your proposal and site, including the current Territory Plan and relevant statutory requirements.

Detailed Explanation

In the ACT planning system, an earlier approval on another block does not operate as a binding precedent for a later DA. Development applications are assessed against the relevant statutory requirements, planning policies, Assessment Outcomes and mandatory Assessment Requirements of the Territory Plan.

The Territory Planning Authority must also consider the suitability of the proposed development in the context of the site and surrounds, its probable impacts and its interaction with adjacent development. This means existing or older developments can form part of the surrounding context, but they do not replace the planning assessment required for the new proposal.

This distinction is particularly important for older developments because planning controls can change over time. A development lawfully approved under an earlier planning framework does not establish that the same design would satisfy the requirements applying to a DA lodged today.

Our planning services can review relevant nearby approvals and compare them with the current planning controls applying to your block, helping determine whether a similar development approach remains

Key Point

No minimum block size does not remove the need for planning assessment.
