What kind of footings are required when there are no manufacturer's instructions?

When no manufacturer's instructions are available for footings in manufactured housing, adhering to typical building codes is essential. Building codes provide standardized guidelines to ensure the structural integrity and safety of the home. These codes take into account various factors such as load-bearing requirements, local climate, and potential environmental hazards. By following these established codes, builders can ensure that the foundation is adequate to support the manufactured home, reducing risks related to settling, shifting, or structural failure over time.

In contrast, selecting a minimum depth or varying practices based on local soil conditions might not provide a comprehensive solution, as these do not necessarily consider all pertinent safety factors outlined in building codes. Additionally, having no specific requirements could lead to potential hazards and is not a responsible approach in construction. Therefore, following typical building codes is the most reliable guideline when no specific instructions are given by the manufacturer.
