Frequently Asked Questions

No, we do not approve class 2-to-9 buildings. We approve class 1 and class 10 buildings only. We cannot approve a change of use for a business or building work in apartment buildings.

We can help you with any class 1 and 10 building approval, including single dwellings, renovations, dual occupancies, alterations, additions, granny flats, pools, studios, garages and demolitions.

We provide building approvals mostly in these Sydney council areas: Bayside, Burwood, Canada Bay, Canterbury, Georges River, Hunters Hill, Inner West, Lane Cove, Mosman, North Sydney, Northern Beaches, Randwick, Ryde, Strathfield, Sutherland, Sydney, Waverley, Willoughby and Woollahra.

Complying Development is a planning and development assessment process in New South Wales that allows for certain types of low-impact building and development projects to be approved quickly and efficiently, by private certifiers, without the need for a full development application to the local council.

A construction certificate is required to be issued by the building certifier before building works can start. The construction certificate verifies that the construction plans are consistent with the development consent (DA) and comply with the building code of Australia (BCA).
