What is a Level 1 Alteration in Florida Building Code (FBC)?

Friday, March 22, 2019

 Level 1 Alterations “include the removal and replacement or the covering of exisitng materials, elements, equipment, or fixtures using new materials, elements, equipment, or fixtures that serve the same purpose.” Replacing door or windows, without changing size or locations, would be an example of a Level 1 Alteration. The alterations must comply with Chapter 7 of the Florida Building Code - Existing Building.


    Level 2 Alterations “include the reconfiguration of space, the addition or elimination of any door or window, the reconfiguration or extension of any system, or the installation of any additional equipment." Adding doors or windows at new locations, or moving interior walls, would be examples of a Level 2 Alteration. The alterations must comply with Chapter 7 for Level 1, plus Chapter 8 of the code.

    Level 3 Alterations “apply where the work area exceeds 50 percent of the building area.” So, essentially, Level 1 is replacement, Level 2 is replacement with changes, and Level 3 is a major remodeling. Level 3 must comply with Chapters 7, 8, and 9 of the Florida Building Code - Existing Building

    So, essentially, Level 1 is replacement, Level 2 is replacement with changes, and Level 3 is a major remodeling.
