Deferred commencement consent (NSW)
A deferred commencement consent is a NSW development consent granted but not operative until the applicant satisfies the consent authority on a specified matter.
Ask Chalkline about this →A deferred commencement consent is a NSW development consent that is granted but does not operate until the applicant satisfies the consent authority on a specified matter, such as an engineering investigation, flood study, or contamination report. The power sits in section 4.16(3) of the Environmental Planning and Assessment Act 1979 (NSW). It differs from a standard consent, which is operative the moment it is granted. For example, a council may grant consent for a house on flood-prone land but defer commencement until a flood study confirms the finished-floor level is acceptable.
The practical effect: the consent exists on paper but you cannot act on it, and no construction certificate can issue, until the deferred matter is resolved to the consent authority’s satisfaction. Providing the documentation is necessary but not sufficient: the authority must also decide it is satisfactory. Until then the consent is dormant.
Deferred commencement conditions are uncommon on straightforward residential DAs, but they appear on flood-prone land, contaminated sites, or where an engineering investigation is outstanding. A common trap is treating the consent as operative and selling, refinancing, or starting work against it before the deferred condition is discharged. Confirm every deferred matter is satisfied in writing before relying on the consent for any downstream purpose. See how to read conditions of consent for where this sits in the consent schedule.
Also known as: Deferred commencement DA, s4.16(3) consent, deferred commencement condition.
