Not all plan sets will have a Floor Framing Plan sheet. Single story homes designed to be built using a slab foundation will not have a Floor Framing Plan sheet because the floor of the home is the slab foundation. However a home designed to be built on a slab foundation that also has a second story will have a floor framing plan for the second story. Homes designed to built with a basement or crawlspace will also have a Floor Framing Plan sheet.
The Floor Framing Plans provide structural information such as the joist location, spacing and direction, as well as the floor heights and stair openings. There is also typically numerous call-outs (notes) that indicate the type of floor trusses that are needed as well as information of truss supports and support locations. All Floor Framing Plans are for design purposes only and will require review by an engineer and/or truss designer to ensure conformity to local site conditions and allowance for given structural loads based on your climate and roofing materials selected.
