Abstract: A floor frame assembly for modular housing units that includes longitudinally extending floor support beams and transverse supports that are attached to and extend outwardly from an outer one of the longitudinal floor support beams to support an edge portion of the floor assembly. The transverse supports have an outer end substantially less than the height of the end that is secured to the outer beam. A hanger is secured to the outer edge of each of the transverse supports. The height of the hanger is greater than the height of the outer end edge so that a gap is created between the bottom of the outer end and the bottom of the hanger to facilitate the attachment of the hanger to a sill plate of a foundation.
