Disclosed is a floor assembly for a modular building unit that avoids the need to turn the floor assembly frame over for installation of a floor subsheet, and that likewise provides a modular floor subsheet that may be fitted to the modular building unit without welding, rivets, screws, or other tooling. A floor assembly frame includes side rails that form the exterior, bottom perimeter of the modular building unit, and joists that extent between parallel side rails of the floor assembly frame. The joists are configured at their base on one side with a slot configured to receive one end of a section of a floor subsheet. An opposite end of the floor subsheet is then positioned overtop the joist element that forms the top portion of the slot on an adjacent joist, which opposite end may then be held in place with a pin, clip, or other fastener requiring minimal effort to install. Such assembly allows all components of the floor to be installed from above, thus avoiding the need to invert the frame of the floor assembly during installation. Likewise, the modular nature of the assembly allows installation to be carried out by fewer personnel than required in traditional installations.
