Changes to the Federal Manufactured Home Construction and Safety Standards Effective March 15, 2021
 
The U.S. Department of Housing & Urban Development (HUD) has finalized a set of changes in the construction standards for manufactured homes which will go into effect on March 15, 2021. These include:
 
  • Data Plate: The data plate on each home will now include whether the home is designed to accommodate additional loads imposed by the attachment of an attached accessory building or structure.
  • Interior Passages: There is included an exception to the requirement for doors to closets, pantries and doors to toilet compartments in single-section homes, since single-section homes have a smaller living space than multi-section homes.
  • Stairways: Changes were made to stairway requirements for multiple story manufactured homes.
  • Carbon Monoxide Detectors: HUD Changed references from “detector” to “alarm” and include specific locations where these must be installed as opposed to just referencing the general standards such as the National Fire Protection Association Standard 720.
  • Factory Constructed or Site-Built Attached Garages and Carports: HUD clarified the differences between garages and carports attached to homes and site-built, self-supported garages. It further states the self-supported garage is considered an add-on subject to Section 3282.(j)(1) and state and local authorities. As for carports, the manufactured may provide the maximum live and dead loads and other design limitations or restrictions.
  • Water Distribution: HUD added relief pipe turndown requirements stating that exterior relief drains shall be directed down and shall terminate 6” to 24” above the finished grade. This is high enough to prevent backflow, but low enough to reduce risk of injury.
