What is the minimum size of a mobile/manufactured home per HUD standards?

Tuesday, December 25, 2018

A manufactured home must be a minimum of 400 square feet to meet the standards set by HUD (U.S. Department of Housing and Urban Development), which has had jurisdiction over the construction of mobile homes since July 15, 1976. Other minimum HUD standards include:

  • Ceiling height of 7 feet, except 6 feet 6 inches in hallways and closets.
  • Two exterior doors for emergency exit, that must be located at least 12 feet apart in a single-wide and 20 feet apart in a double-wide.
  • Every bedroom must have a window
  • Bathrooms and kitchen must have mechanical ventilation
  • The home's foundation and tie-downs must meet HUD standards, except that Florida has somewhat stricter tie-down requirements.

    A Park Model RV, on the other hand, looks similar to a small mobile home, but is titled as a recreational vehicle, and cannot exceed 400 square feet. Construction is governed by different standards issued by ANSI (American National Standards Institute). 


    Florida has a special exemption that allows a home of 400 to 500 square feet to be titled as a Park Model RV if built to HUD standards. The Florida HUD Park Models will not have some features offered with regular park models, such as a sleeping loft, because they do not comply with HUD code.
