In what scenario might a manufactured home NOT require building permits?

In the context of manufactured homes, a scenario where a manufactured home might not require building permits is when it is certified by HUD. The U.S. Department of Housing and Urban Development (HUD) establishes rigorous standards for manufactured homes, known as the HUD Code, which ensures the quality and safety of these homes. When a manufactured home is certified by HUD, it indicates that the home meets these federal construction and safety regulations.

As a result, local authorities may have confidence that the home adheres to the necessary building standards, potentially alleviating the need for additional local building permits. It's important to note that even if a home is certified by HUD, there may still be specific local codes and zoning laws that need to be adhered to, which can vary by jurisdiction. However, the HUD certification is a key factor that can contribute to the exemption from the requirement for building permits in some cases.
