Answer:
Yes — you can engage your own certifier, particularly if you’re choosing the DIY Kit option. However, if you proceed with Expandify’s Complete Package, certification is coordinated by our team to ensure documentation, inspections, and approvals are completed smoothly.

If you choose your own certifier, they must:

• Be licensed in your state or territory
• Understand Class 1a prefabricated housing
• Be available to conduct pre- and post-installation inspections
• Accept Expandify’s engineering and compliance documentation

We’re happy to work with your certifier or recommend one experienced in modular housing approvals.
