Answer:
Yes — all Expandify homes require official approval before installation. In most cases this is a private certifier’s approval (e.g. a Complying Development Certificate) or a council-issued building permit, depending on your state. Every Expandify dwelling must be approved and certified to meet local regulations prior to installation.

The approval process may include:

• A Complying Development Certificate (CDC), which is a faster approval pathway for compliant blocks
• A Development Application (DA) if your property falls under complex zoning or planning overlays
• A review of bushfire, flood, acoustic, or heritage overlays
• A Preliminary Council Assessment Report (PCAR), which Expandify completes for you

Expandify manages the full approval process for Complete Package customers and provides documentation for DIY Kit users.
