Approvals and certification
Building permits, OC, CC, certifiers.
Getting the paperwork right before you start, and at every inspection, is one of the cleaner ways to avoid defect liability and final-certificate delays. This pillar covers the approval chain from construction certificate (NSW) or building permit (VIC, QLD) through to occupancy certificate or certificate of occupancy, and the inspection stages in between.
It is for builders and owner-builders who need to know who to engage (private certifier, local council, Relevant Building Surveyor in VIC), what documents are required at each stage, what triggers a mandatory inspection, and what happens when a structure is built without approval. Coverage includes CDC pathways and when they are faster than DA, the role of the principal certifier under the Environmental Planning and Assessment Act 1979 (NSW), and how inspection regimes differ between states.
Chalkline treats approvals as process, not bureaucracy. Each article explains what the step is for and what goes wrong when it is skipped or botched, because that is what builders actually need to know.
