Which of the following is a feature required to be compliant for manufactured homes?

For manufactured homes, the requirement for steps and rails is crucial for ensuring safety and accessibility. These features are necessary for facilitating safe access to and from the home, particularly when there is a significant elevation from the ground level. The installation of steps provides a safe means for residents and visitors to enter and exit the home, while railings enhance security and stability while navigating stairs.

In contrast, the other options like architectural design approval, landscaping requirements, and permanent foundations may not be universally mandated for compliance across all manufactured homes. While certain local codes or regulations may require unique architectural features or landscaping, these are not standard compliance requirements for all manufactured homes. Permanent foundations may also vary based on local regulations and the type of manufactured home. Thus, the presence of steps and rails stands out as a fundamental safety requirement that is widely recognized in compliance standards for manufactured homes.
