If you are subdividing land in Mosman, a Section 73 Compliance Certificate from Sydney Water is one of the key approvals you will need, and we handle the whole process for you. At All Spec Approvals we specialise in Section 73 applications for Mosman projects, managing the paperwork, the servicing coordination and the back and forth with Sydney Water so your subdivision keeps moving. We take a process that trips up a lot of developers and make it straightforward.
Understanding Section 73 for Mosman Subdivisions
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 in Mosman?
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.
-

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

Getting Section 73 Subdivision Applications Right for Your Mosman Project
Section 73 Subdivision Applications is one of the first things that can hold up a build in Mosman, and one of the most costly to fix once work is underway. We look at what your Mosman project needs, coordinate the Section 73 and Sydney Water coordination, and make sure everything meets the relevant standards before it goes in for assessment. Sorting it at the planning stage gives you a realistic budget and timeline from day one.
Good Section 73 subdivision applications is about more than paperwork. We look at the whole picture of your Mosman project, from the technical detail to the approval conditions, and give you advice you can act on. That early input regularly saves developers time and money by avoiding reworks and keeping the project on schedule.
