ss. 704.8.2, 706.1, 707, 716.2.2, 716.5.4, 716.6.1, 716.6.2, 716.6.3, 717.5, 719.			Change reference from the “International Mechanical Cod, the International Fire Code or the International Plumbing  Code” to the “Florida Mechanical Code,  the Florida Fire Prevention Code or the Florida Plumbing Code, Building ” as applicable.	
701.1 Scope Provides requirements for materials and assemblies for fire-resistant construction.

		8.2.1 Refers to NFPA 220 for construction classification.

8.2.1.2* NFPA 220, Standard on Types of Building Construction,
shall be used to determine the requirements for the construction
classification.
8.2.1.3 Where the building or facility includes additions or
connected structures of different construction types, the rating
and classification of the structure shall be based on one of
the following:
(1) Separate buildings, if a 2-hour or greater vertically
aligned fire barrier wall in accordance with NFPA 221,
Standard for Fire Walls and Fire Barrier Walls, exists between
the portions of the building
	Revise s.8.2.1.2 to reference the FBC instead of NFPA 220.  Also, revise 8.2.1.3(1) to change “2-hour” to “4-hour” fire barrier wall for separate buildings.

705.1 General Parts of buildings separated by walls considered to be separate buildings. No openings allowed when located on property lines.
		8.2.1 Additions and connected structures considered separate if separated by 2-hour fire wall.

	See above.	
705.4
Table 705.4
Fire-Resistance Rating Fire-resistance rating must meet Table 705.4. Requires four hours for high hazard uses; three hours for most other occupancies and two hours for
low hazard factory, storage, single family uses, and
when Type II or V construction in assembly, business, educational, H-4, institutional, multi-family residential, and utility.

		8.2.1 Two-hour construction required.	See above.	
Table 705.4 Fire Wall Fire-Resistance Ratings Fire resistance rating for fire walls depending on occupancy group.			8.2.1.3	Additions and connected structures considered separate if separated by 2-hour fire wall.	See above.	
706.3.5	Incidental Use Areas. The fire barrier separating incidental use areas must have a fire-resistance rating per Table 302.1.1.	

706.3.5 Incidental use areas. The fire barrier separating incidental use areas shall have a fire-resistance rating of not less than that indicated in Table 302.1.1.
		6.1.14.1.2 Incidental use areas are not required to be separated.

6.1.14.1.2* Where incidental to another occupancy, areas used as follows shall be permitted to be considered part of the predominant occupancy and shall be subject to the provisions of the Code that apply to the predominant occupancy:
(1) Mercantile, business, industrial, or storage use
(2)*Nonresidential use with an occupant load fewer than that established by Section 6.1 for the occupancy threshold
	Revise 6.1.14.1.2, NFPA 101 for consistency with 706.3.5, IBC. 	
706.3.6	Separation Of Mixed Occupancies.	If Section 302.3.2 applies, the fire barrier separating mixed occupancies must have a fire-resistance rating per Section 302.3.2 based on the occupancies being separated.			6.1.14.3
6.1.14.4	Mixed occupancies are not required to be separated.  Separated occupancies must be separated per Table 6.1.14.4.1.

6.1.14 Multiple Occupancies.
[See 6.1.14.1 through 6.1.14.4.4 and Table 6.1.14.4.1 on pages 101-39 and 101-40]

3.3.152.11 Multiple Occupancy. A building or structure in which two or more classes of occupancy exist.

3.3.152.10 Mixed Occupancy. A multiple occupancy where the occupancies are intermingled.

3.3.152.14 Separated Occupancy. A multiple occupancy where the occupancies are separated by fire resistance–rated assemblies.

[See also the 1.2 subsection of each occupancy chapter – Chapter 12 through 	Recommend deferring to the FBC, Table 704.1 and Section 704.1 with regard to occupancy separation.  Also, recommend deleting all provisions that are building code/NFPA 5000 related.

Joint Fire TAC action:
Approved the above as amended and clarification to say that Table 6.1.14.4.1 to be replaced by the contents of Table 704.1. 302.3.2  Section 704.1 302.3.2 to be included in Chapter 8 or Chapter 6 as appropriate.
