What’s Included in a Building Certifier’s Fee in NSW?

When you get a quote from a building certifier, it’s not always obvious what you’re actually paying for. Certifiers structure their fees differently, and a lower headline number doesn’t always mean a lower total cost. This guide breaks down what a certifier’s fee should cover, what might be charged separately, and how to make sure you’re comparing quotes on a level playing field.

What does a building certifier’s fee typically cover?

A comprehensive building certifier fee in NSW usually covers four core components:

1. The building certificate. This is either a Complying Development Certificate (CDC) or a Construction Certificate (CC), depending on your approval pathway. The certifier assesses your plans and documentation against the National Construction Code (NCC), relevant Australian Standards, and either the SEPP standards (for a CDC) or your conditions of consent (for a CC). If everything complies, the certificate is issued.

2. Principal Certifier (PC) appointment. Before building work starts, a Principal Certifier must be appointed under the Environmental Planning and Assessment Act 1979. The PC oversees compliance during construction and is responsible for the mandatory inspections. In most cases, the same certifier who issues the certificate is appointed as PC.

3. Mandatory critical stage inspections. For Class 1 and 10 buildings (houses, granny flats, garages), there are six mandatory inspections set out in the EP&A (Development Certification and Fire Safety) Regulation 2021, Section 61. These cover excavation and footings, reinforced concrete, framework, waterproofing, stormwater drainage, and the final inspection. A good certifier attends each of these on site in person.

4. Occupation Certificate (OC). The Occupation Certificate is issued after the final inspection confirms the building is safe and suitable for occupation. This is the certificate that allows the building to be legally occupied.

When a certifier bundles all four components into one fee, you have a clear picture of the total cost from start to finish. When they’re priced separately, you need to add them up to get the real number.

Are there hidden fees in building certification?

Hidden fees aren’t standard practice, but additional charges can appear if you haven’t asked the right questions upfront. The most common extras to watch for:

Re-inspection fees. If work fails a mandatory inspection and needs to be redone, the certifier may charge for the follow-up visit. This is reasonable, since the re-inspection requires additional time and travel. But it should be disclosed upfront so you’re not caught off guard. The builder is usually responsible for the work being ready for inspection, so re-inspection costs are often a builder issue rather than a homeowner issue.

Additional inspections. The six mandatory inspections are the minimum. Some projects need extra inspections, particularly complex builds, staged construction, or situations where the certifier identifies issues that require closer monitoring. Ask whether additional inspections are charged separately and at what rate.

Travel surcharges. Some certifiers charge extra for travel to sites outside their primary service area, particularly regional projects or outer suburban locations.

Plan amendment fees. If your plans change after the certificate is issued (which happens more often than you’d think), the certifier needs to reassess the amended plans. Some certifiers include minor amendments in their fee, others charge separately.

Administration and lodgement fees. Some certifiers charge a separate administration fee for document handling or portal lodgement. The NSW Planning Portal charges $47 per lodgement, which is a government fee. A reputable certifier will pass this through at cost without mark-up.

Do I pay extra for inspections during the build?

This depends entirely on how your certifier structures their pricing. There are two common approaches:

Bundled pricing: The certifier includes the certificate, PC appointment, all six mandatory inspections, and the OC in a single fee. This is the simplest approach and gives you cost certainty. You know exactly what you’ll pay from start to finish.

Itemised pricing: The certifier charges separately for the certificate assessment, the PC appointment, each inspection, and the OC. This can be useful for transparency, but you need to add everything up to compare with a bundled quote.

If inspections are priced separately, expect around $200 to $500 per mandatory inspection, depending on location and project complexity. With six mandatory inspections, that adds $1,200 to $3,000 to the total. Factor this in when comparing a low “certificate only” fee against a higher bundled package.

How do council fees compare to private certifier fees?

Both council and private certifiers can issue CDCs, CCs, and OCs in NSW. The legal authority and assessment standards are identical. But the fee structures differ.

Council fees are typically calculated as a percentage of the estimated construction value, plus fixed charges for specific services. This means a higher-value project will attract higher council fees, even if the certification complexity is similar to a lower-value project. Council timelines also tend to be longer, and communication can be less direct.

Private certifier fees are usually quoted as a flat rate based on the project scope. This makes them more predictable and often more competitive, particularly for higher-value builds. Private certifiers also tend to offer faster turnaround on assessments, more responsive communication, and more flexibility with inspection scheduling.

The trade-off is not about quality of assessment. Private certifiers are registered under the Building and Development Certifiers Act 2018 and subject to audit by Building Commission NSW. They’re held to the same regulatory standards as council.

What’s the real difference between a cheap and expensive certifier?

Not all certifiers deliver the same level of service, even though they all have the same legal authority. The main differences tend to come down to:

What’s included in the fee. A cheaper quote often excludes inspections, the OC, or other components. Once you add those back in, the total may not be much different from the “more expensive” bundled quote.

How inspections are conducted. Some certifiers attend every mandatory inspection in person. Others accept photos from the builder for some or all inspections. In-person inspections provide significantly better compliance oversight, but they take more time and cost more. This is one of the most important differences to understand. For more on this, see our article on the risks of choosing the cheapest certifier.

Depth of plan assessment. A thorough certifier reviews your documentation in detail, identifies potential compliance issues early, and flags items that may need attention before construction starts. A less thorough assessment may approve plans more quickly but miss issues that surface during the build or, worse, after completion.

Communication and responsiveness. During construction, you need your certifier to respond quickly when inspections are due. Delays in scheduling inspections can hold up the build. A certifier who is hard to reach or slow to schedule inspections can cost you more in construction delays than the fee difference would have saved you.

What questions should I ask before choosing a certifier?

When comparing quotes, these questions will help you understand the true value of each option:

Does the fee include the certificate, PC appointment, all six mandatory inspections, and the OC? Are re-inspections charged separately, and if so, at what rate? Do you attend every inspection in person, or do you accept photos for some stages? Is the $47 Planning Portal lodgement fee included or additional? What happens if my plans need to change after the certificate is issued? How quickly do you typically schedule inspections after being notified? What additional inspections, if any, do you typically recommend beyond the six mandatory stages?

A certifier who answers these questions clearly and transparently is usually one who takes their role seriously. Vague or evasive answers about what’s included should be a red flag.

Frequently asked questions

What is typically included in a building certifier’s fee?

A comprehensive fee usually covers the building certificate (CDC or CC), Principal Certifier appointment, six mandatory inspections, and the Occupation Certificate. Some certifiers bundle everything, others charge separately. The $47 Planning Portal fee may be additional.

Are there hidden fees in building certification?

Not typically, but watch for re-inspection fees, additional inspection charges, travel surcharges, plan amendment fees, and administration fees. Request an itemised quote and ask specifically about any charges not listed.

Do I pay extra for inspections during the build?

It depends on the certifier. Many include all six mandatory inspections in their overall fee. If priced separately, expect $200 to $500 per inspection. Always confirm what’s included before committing.

How do council certifier fees compare to private certifier fees?

Council fees are typically a percentage of construction value, making them less predictable. Private certifiers usually quote a flat rate. The quality of assessment is the same, but private certifiers generally offer faster turnaround and more responsive communication.

What’s the difference between a cheap and expensive building certifier?

The main differences are scope of services included and thoroughness of inspections. Cheaper certifiers may exclude inspections, accept builder photos instead of attending site, or conduct less detailed reviews. A higher fee often reflects more comprehensive, hands-on service.

Key takeaways

• A comprehensive certifier fee covers four components: the certificate, PC appointment, mandatory inspections, and the OC.
• Not all quotes include the same components. Always compare like with like.
• Common additional charges include re-inspections, extra inspections, travel surcharges, and plan amendment fees.
• Private certifiers and council have the same legal authority. Private certifiers usually offer faster turnaround and flat-rate pricing.
• The biggest difference between certifiers is often how they conduct inspections: in-person vs photo-based.
• Ask detailed questions before committing. A transparent certifier will welcome them.
