Residential Building Inspector Practice Exam

What must the bottom frame of a manufactured home be located above?

1. Ground level

2. Design flood elevation

3. Base flood elevation plus one foot

4. Surface water level

The correct answer is: Base flood elevation plus one foot

The bottom frame of a manufactured home must be located above the base flood elevation plus one foot to ensure the structure is adequately elevated to minimize flood risk. This requirement is based on the need to protect manufactured homes from potential flooding, especially in areas prone to high waters. Elevating them above the base flood elevation takes into account the anticipated flood levels, and adding an additional foot provides a safety margin that addresses variations in water levels and potential future changes in flood risk. This elevation standard is often determined by local building codes and floodplain management regulations, which are designed to safeguard properties and lives by ensuring that manufactured homes can withstand flooding events. It reflects an understanding of the dynamics of water movement and the need for resilience in residential structures.
