Direct answer
Float is a defined term in the International Fire Code (IFC) 2009, in Marinas. The code's own words are: “A floating structure normally used as a point of transfer for passengers and goods, or both, for mooring purposes.” No other I-Code in this corpus defines it, so the IFC 2009 definition is the one to work from. The term is used in 11 chapters of this corpus, most often in Motor Fuel-dispensing Facilities and Repair Garages (IFC 2009), Flammable and Combustible Liquids (IFC 2009), Marinas (IFC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted. Record the jurisdiction, the adopted edition, the application date and any local amendment that rewrites the definition before you use it on a live project, because a term redefined by amendment changes every requirement that depends on it.

Frequently asked questions
What is the code definition of float?
The International Fire Code (IFC) 2009 defines it in Marinas as: “A floating structure normally used as a point of transfer for passengers and goods, or both, for mooring purposes.” The 2009 model text is reproduced here; the definition that binds your project is the one in the edition your jurisdiction has adopted, as amended locally.
Which parts of the code depend on float?
In this corpus the term is used across 11 chapters, led by Motor Fuel-dispensing Facilities and Repair Garages in the IFC 2009. Those are the sections whose scope moves if the definition is amended locally, so read them together with Chapter 2 rather than on their own.
What is a float in a building?
In the 2009 I-Codes hosted here it is a defined term rather than a description. The IFC 2009 states, in Marinas: “A floating structure normally used as a point of transfer for passengers and goods, or both, for mooring purposes.” It is defined in IFC 2009. It is not the same as Building, which the IBC 2009 defines separately as “Any structure used or intended for supporting or sheltering any use or occupancy.” Because it is a defined term, whatever the adopted edition says it means is what every section using it means — so check Chapter 2 of that edition and any local amendment before relying on this wording.
