The repair, alteration, change of occupancy, addition or relocation of all existing buildings shall comply with one of the methods listed in Sections 301.1.1 through 301.1.3 as selected by the applicant. Sections 301.1.1 through 301.1.3 shall not be applied in combination with each other. Where this code requires consideration of the seismic force-resisting system of an existing building subject to repair, alteration, change of occupancy, addition or relocation of existing buildings, the seismic evaluation and design shall be based on Section 301.1.4 regardless of which compliance method is used.

Exception: Subject to the approval of the code official, alterations complying with the laws in existence at the time the building or the affected portion of the building was built shall be considered in compliance with the provisions of this code unless the building is undergoing more than a limited structural alteration as defined in Section 907.4.4. New structural members added as part of the alteration shall comply with the Florida Building Code, Building. Alterations of existing buildings in flood hazard areas shall comply with Section 701.3.

Repairs, alterations, additions and changes of occupancy complying with Chapter 4 of this code in buildings complying with the Florida Fire Prevention Code shall be considered in compliance with the provisions of this code.
Repairs, alterations, additions, changes in occupancy and relocated buildings complying with the applicable requirements of Chapters 5 through 13 of this code shall be considered in compliance with the provisions of this code.
Repairs, alterations, additions, changes in occupancy and relocated buildings complying with Chapter 14 of this code shall be considered in compliance with the provisions of this code.
The seismic evaluation and design shall be based on the procedures specified in the Florida Building Code, Building or ASCE 41. The procedures contained in Appendix A of this code shall be permitted to be used as specified in Section 301.1.4.2.

Where compliance with the seismic design provisions of the Florida Building Code, Building is required, the criteria shall be in accordance with one of the following:

  1. One-hundred percent of the values in the Florida Building Code, Building. Where the existing seismic force-resisting system is a type that can be designated as “Ordinary,” values of R, Ω0 and Cd used for analysis in accordance with Chapter 16 of the Florida Building Code, Building shall be those specified for structural systems classified as “Ordinary” in accordance with Table 12.2-1 of ASCE 7, unless it can be demonstrated that the structural system will provide performance equivalent to that of a “Detailed,” “Intermediate” or “Special” system.
  2. ASCE 41, using a Tier 3 procedure and the twolevel performance objective in Table 301.1.4.1 for the applicable risk category.

Where seismic evaluation and design is permitted to meet reduced Florida Building Code, Building seismic force levels, the criteria used shall be in accordance with one of the following:

  1. The Florida Building Code, Building using 75 percent of the prescribed forces. Values of R, Ω0 and Cd used for analysis shall be as specified in Section 301.1.4.1 of this code.
  2. Structures or portions of structures that comply with the requirements of the applicable chapter in Appendix A as specified in Items 2.1 through 2.5 and subject to the limitations of the respective Appendix A chapters shall be deemed to comply with this section.

    1. 2.1. The seismic evaluation and design of unreinforced masonry bearing wall buildings in Risk Category I or II are permitted to be based on the procedures specified in Appendix Chapter A1.
    2. 2.2. Seismic evaluation and design of the wall anchorage system in reinforced concrete and reinforced masonry wall buildings with flexible diaphragms in Risk Category I or II are permitted to be based on the procedures specified in Chapter A2.
    3. 2.3. Seismic evaluation and design of cripple walls and sill plate anchorage in residential buildings of light-frame wood construction in Risk Category I or II are permitted to be based on the procedures specified in Chapter A3.
    4. 2.4. Seismic evaluation and design of soft, weak, or open-front wall conditions in multiunit residential buildings of wood construction in Risk Category I or II are permitted to be based on the procedures specified in Chapter A4.
    5. 2.5. Seismic evaluation and design of concrete buildings assigned to Risk Category I, II or III are permitted to be based on the procedures specified in Chapter A5.
  3. ASCE 41, using the performance objective in Table 301.1.4.2 for the applicable risk category.

An agency or local government may not require that existing mechanical equipment located on or above the surface of a roof be installed in compliance with the requirements of the Florida Building Code except during reroofing when the equipment is being replaced or moved and is not in compliance with the provisions of the Florida Building Code relating to roof-mounted mechanical units.

The provisions of Section 302 apply to all alterations, repairs, additions, relocations of structures and changes of occupancy regardless of compliance method.
Alterations, repairs, additions and changes of occupancy to, or relocation of, existing buildings and structures shall comply with the provisions for alterations, repairs, additions and changes of occupancy or relocation, respectively, in this code and the Florida Building Code, Energy Conservation; Florida Fire Prevention Code; Florida Building Code, Fuel Gas; Florida Building Code, Mechanical; Florida Building Code, Plumbing; Florida Building Code, Residential and NFPA 70. Where provisions of the other codes conflict with provisions of this code, the provisions of this code shall take precedence.

Except as otherwise required or permitted by this code, materials permitted by the applicable code for new construction shall be used. Like materials shall be permitted for repairs and alterations, provided no unsafe condition is created. Hazardous materials shall not be used where the code for new construction would not permit their use in buildings of similar occupancy, purpose and location.
