Alterations and additions
Alterations and additions cover everything from a rear extension to a first-floor addition. The approval pathway depends on the codes, the existing building and site constraints.
Choosing the pathway
Some alterations can proceed as complying development. Others need development consent and a construction certificate. Heritage, flooding, bushfire and the existing approval history commonly decide which path applies.
Existing buildings
Additions often touch older fabric. The certification pack must show how the proposed work meets the NCC and the approval. Incomplete existing-building information is a frequent reason applications stall.
Questions about alterations and additions
Do small renovations still need a certificate?
Many building alterations require a CDC or CC before work starts. Exempt development has its own limits. If you are unsure, request a fee proposal with a short description of the work.
