When is a Section J Report required?

A Section J Report is required for most new commercial buildings and major refurbishments in Australia. It applies to Class 3 to 9 buildings, such as offices, shops, schools and warehouses.

Short answer

You need a Section J Report before you can obtain a construction certificate for any new commercial building or substantial retrofit.

Full answer

If you are planning a new development that is not a residential dwelling, a Section J Report is likely required. This includes:

• New offices, childcare centres, hospitals or hotels
• Industrial or warehouse developments
• Additions or major renovations to existing commercial buildings

Section J compliance must be demonstrated at the construction certificate stage, whether using Deemed-to-Satisfy or JV3 methods.

Why this matters

Without a valid Section J Report, your certifier cannot approve your project. Early assessment also prevents costly redesigns or delays.
