5-over-1 or over-1s, also known as a one-plus-five or a podium building, is a type of multi-family residential building commonly found in urban areas of North America. The mid-rise buildings are normally constructed with four or five wood-frame stories above a concrete podium, usually for retail or resident amenity space. The name derives from the maximum permissible five floors of combustible construction (Type III or Type V) over a fire-resistive Type I podium of one floor for "5-over-1" or two floors for "5-over-2", as defined in the United States–based International Building Code (IBC) Section 510.2. Some sources instead attribute the name to the wood framing of the upper construction; the IBC uses "Type V" to refer to non-fireproof structures, including those framed with dimensional lumber. The style of buildings originated with the work of architect Tim Smith in Los Angeles, who took advantage of a change in construction code allowing the use of fire-retardant treated wood (FRTW) to construct buildings up to five stories. From this he saw that what became the "Five-Over-One" model would bring the construction costs down substantially, making a 100-unit affordable housing project financially viable. The style gained popularity following revisions in the 2000 IBC edition, and it exploded in popularity in the 2010s, following a 2009 revision to the IBC, which allowed up to five stories of wood-framed construction.
