They are useful, but they are also frequently misunderstood.

In the NSW planning system, deferred commencement conditions are often used as a practical way to approve development while requiring an applicant to resolve a specific issue before the consent becomes operational.

Consent authorities sometimes attempt to use deferred commencement conditions to postpone major planning questions or to shift unresolved issues onto applicants after approval. That approach can create legal problems.

This article explains what deferred commencement conditions are, when they can be used, and some of the common mistakes that occur.

What is a Deferred Commencement Condition?

Under section 4.16(3) of the Environmental Planning and Assessment Act 1979, a consent authority can grant development consent subject to a deferred commencement condition.

A deferred commencement condition means that:

1. consent is granted; but
2. the consent does not operate until the specified condition is satisfied.

Once the condition is satisfied, the consent authority generally confirms this in writing and the development consent becomes operative.

This mechanism allows certain issues to be resolved after the consent is granted, but before the development can begin.

When Are Deferred Commencement Conditions Appropriate?

Deferred commencement conditions are most appropriate where:

1. the development is acceptable in principle; and
2. a discrete issue still needs to be resolved.

In other words, the consent authority must already be satisfied that the development should be approved.

The deferred commencement condition should only deal with a specific outstanding matter, not the core merits of the proposal.

The Key Legal Principle

The courts have made it clear that a deferred commencement condition cannot be used to postpone the decision about whether the development should be approved.

The consent authority must determine the development application on its merits before granting consent.

If an issue goes to the fundamental acceptability of the development, it cannot be deferred.

Common Mistakes

1. Deferring a core planning issue

One of the most common problems is where a deferred commencement condition effectively asks the applicant to prove the development is acceptable after consent is granted.

For example, a condition might require the applicant to submit a report demonstrating that the development will not have unacceptable impacts.

If that issue goes to the core planning merits, it should be resolved during the assessment of the development application.

Using a deferred commencement condition in this way can mean the consent authority has failed to determine the application properly.

2. Deferring Major Design Changes

Deferred commencement conditions should not be used to allow significant redesign of a proposal.

If the condition allows substantial changes, then the development being approved may be different to the development that was assessed.

That creates uncertainty about what has actually been approved.

3. Deferring Information

Another common issue is where councils approve a development application but require the applicant to provide important information later.

If the information is necessary to assess the impacts of the development, it should generally be provided as part of the development application.

A deferred commencement condition should not be used as a substitute for proper assessment.

4. Conditions That Are Too Vague

Deferred commencement conditions must be clear and precise.

The applicant needs to know:

1. exactly what must be done; and
2. how the consent authority will determine whether the condition has been satisfied.

Conditions that require something like “the submission of satisfactory information” can create uncertainty and disputes later.

Practical Lessons

For consent authorities, deferred commencement conditions should be used carefully.

Before imposing one, it is worth asking two simple questions:

1. Is the development acceptable in principle right now?
2. Is the outstanding issue narrow and capable of clear resolution?

If the answer to the first question is no, then the issue should be resolved during the assessment of the development application rather than deferred.

For applicants, deferred commencement conditions can be helpful, but they can also create risk. If the condition is difficult to satisfy, the consent may never become operational.

Final Thoughts

Deferred commencement conditions are a useful tool in the planning system. They allow development consent to be granted while requiring specific matters to be resolved before the consent takes effect.

However, they should not be used to defer the fundamental question of whether the development should be approved.

When used correctly, they can help move projects forward. When used incorrectly, they can create uncertainty, disputes, and potentially invalid consents.

Understanding the limits of deferred commencement conditions is therefore important for both councils and developers navigating the NSW planning system.
