What Does a Building Certifier Look At?
A building certifier plays a crucial role in ensuring your construction project meets all necessary legal and safety requirements. They review building plans and inspect construction work to verify compliance with the National Construction Code (NCC), Building Code of Australia (BCA), and relevant local council regulations.
During plan assessment, certifiers check the proposed design for structural integrity, fire safety measures, energy efficiency, ventilation, moisture control, and accessibility for people with disabilities. Once the build starts, they conduct staged inspections—such as slab, frame, waterproofing, and final completion—to confirm the work matches approved plans and standards.
They also ensure zoning laws, setbacks, and boundary clearances are met and that the building won’t impact public utilities or neighboring properties. In short, a certifier helps protect property owners and occupants by ensuring every element of a build is legally and safely constructed before issuing a Certificate of Occupancy or Completion.
How Much Does a Building Certifier Charge?
Building certifier fees in Australia vary depending on the project type, size, and location. For simple residential jobs like a carport, deck, or home renovation, you might pay between $500 and $1,200. For larger or more complex residential builds, costs can rise to $1,500–$3,000 or more.
Commercial and multi-unit residential developments typically incur higher fees due to increased reporting, multiple site visits, and extra documentation—costing $3,000 to $10,000+, depending on the scope. Some certifiers charge flat rates, while others provide tiered pricing or per-stage fees (e.g. foundation inspection, frame inspection, final approval).
Always confirm what’s included in the fee—such as pre-lodgement advice, documentation review, inspections, and final certification. If you require extra services (like fast-tracking approvals or handling council negotiations), there may be additional costs involved.

Choosing the right building certifier is essential to keeping your project compliant and avoiding delays. Here are key questions to ask before making your decision:
