Private Certifier or Council Approval: Which One Is Right for Your Project?

Every building project in New South Wales needs certification at some stage. That could mean a Complying Development Certificate, a Construction Certificate, or an Occupation Certificate.

The private certifier vs council approval decision affects who handles that work and how the process unfolds. Both are legitimate, registered pathways, but they differ in choice, cost, speed and communication. Understanding the difference before engaging anyone can save time and avoid delays later.

This guide breaks down what each can approve, how fees compare, and how to decide which one suits your project.

What does a private certifier do?

A private certifier is an individually accredited professional, or a firm employing accredited certifiers, registered under the Building and Development Certifiers Act 2018 to assess and certify building work in New South Wales. They operate independently of council, but they are regulated the same way council building surveyors are: registered with Building Commission NSW, and required to assess plans and construction against the National Construction Code (NCC), which includes the Building Code of Australia (BCA).

A private certifier can issue CDCs, CCs and OCs, and can act as Principal Certifier (PC) for the mandatory inspection stages of a build.

What does a council certifier do?

Most local councils employ their own accredited building surveyors, sometimes called council certifiers. They are registered under the same Act and assessed against the same BCA standards as private certifiers; the accreditation requirements do not change based on who employs them.

Council certifiers typically only handle work within that council’s local government area, and a project is assigned to whoever is available rather than chosen individually.

What each option can (and can’t) approve

Under the Environmental Planning and Assessment Act 1979 (EP&A Act), a Development Application (DA) is determined by the consent authority: usually council, though for some developments this is a Sydney planning panel or the Minister. Neither a private certifier nor a council certifier can approve a DA, because that is a planning decision, not a certification one.

Certification works differently. For eligible projects, a CDC can be issued by either a private certifier or a council certifier, under the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 (Codes SEPP). The same applies to a CC, an OC, and the PC role for critical-stage inspections: either option can perform these functions, provided the project qualifies.

Choice, fees, speed and accountability

Choice and appointment

This is one of the clearest practical differences. Engage a private certifier directly, and that person or firm usually stays with the project from lodgement through to sign-off. There is no reassignment part-way through, and no need to re-explain the job to a new duty officer at each stage.

Council certification works differently. Whichever building surveyor is rostered to the file handles it, and there is no ability to select an individual within that council’s team.

How fees compare

Council fees generally follow a published, fixed schedule set by that local government area. It is transparent, but not something you can negotiate or shop around on.

Private certifier fees are set by the market, so quotes vary between firms, which means you can compare pricing before engaging one. A certifier will typically provide a written quote outlining exactly what is included before starting the work.

Speed and communication in practice

How fast either option moves depends on workload. Council capacity is tied to that local government area’s overall caseload, which can mean longer queues during busy periods. Private certifiers generally have more flexibility, since they manage their own caseload and inspection scheduling directly.

Communication style also varies, and it is not strictly tied to which pathway you choose. Some certifiers provide regular proactive updates, while others require the client to follow up. It is worth asking a certifier upfront how they will keep you informed before you engage them.

Accountability if something goes wrong

Both pathways are accountable to Building Commission NSW, which handles registration and complaints against certifiers under the Act. Councils also have their own internal complaints processes for their building surveyors.

One practical difference: because private certifiers operate as businesses competing for work, many have public reviews a reader can check before engaging them. This serves as a form of accountability that is not available for council-employed certifiers.

Which pathway is right for your project?

Whichever pathway you are leaning toward, the decision affects more than paperwork speed: it shapes how much visibility you have over your own project. Getting a certifier involved early, before finalising design or lodging any application, means compliance issues surface while they are still cheap to fix, rather than after construction has started.

A registered certifier can also advise on which certificates a project needs, so you are not guessing at the difference between a CDC pathway and a full DA. If your project is heading toward completion, our occupation certificate checklist covers what needs to be in place before the final inspection, regardless of which pathway you chose.

A private certifier and council approval are both legitimate ways to get the same certificates issued, but they get you there differently. Choosing between the two comes down to how much choice, speed and communication matter for your project.
