    paragraph_quote: 'c. Foundation Systems (02/16/2021) i. New Construction for Manufactured
      Housing (A) Definition New Construction for Manufactured Housing refers to a
      Manufactured Home that has been permanently erected on a site for less than
      one year prior to the case number assignment date. (B) Standard The space beneath
      the house must be enclosed by a continuous foundation type construction designed
      to resist all forces to which it is subject without transmitting forces to the
      building superstructure. The enclosure must be adequately secured to the perimeter
      of the house and be constructed of materials that conform, accordingly, to HUD
      MPS (such as concrete, masonry or treated wood) and the PFGMH for foundations.

      Manufactured Housing refers to a Manufactured Home that has been permanently
      installed on a site for one year or more prior to the case number assignment

      attached to backing made of concrete, masonry, treated wood or a product with
      similar strength and durability. (C) Required Analysis and Reporting If the
