What Is a Section 73
Certificate?

A Section 73 Compliance Certificate confirms that a developer has made the necessary arrangements with Sydney Water for water, sewer, and stormwater infrastructure.

It verifies that:

  • Adequate water supply is available for the lot.

  • Sewerage infrastructure meets the demand of the new development.

  • Developer charges and environmental levies are settled.

  • All required physical works have been constructed.

Without a Section 73 Certificate, your subdivision cannot be legally registered.

When Is a Section 73 Application Required?

You typically require Section 73 Subdivision Applications when:

  • Subdividing land or a lot.

  • Constructing a new duplex.

  • Developing a multi-dwelling property.

  • Converting a building to strata titles.

  • Undertaking commercial or industrial projects that increase water demand.

If your development involves changes to plumbing or increased utility load, a Section 73 Application is essential.

How long does a Section 73 application take?

The timeframe varies depending on the complexity of the requirements, but typically ranges from 4 to 12 weeks once all information is provided.

Can construction begin without a Section 73 Certificate?

While physical building construction can often start, you cannot register your subdivision or finalise your titles without the final Compliance Certificate.
