CHAPTER 2 BUILDING CONSTRUCTION
Conform building construction to fire resistance requirements, allowable floor
area, building height limitations, and building separation distance requirements of
the IBC, except as modified by this UFC.
Egress and Safety to Life.
Comply with NFPA 101 for building construction related to egress and safety to
life. For conflicts between the IBC and NFPA 101 related to fire resistance
rating, conform to NFPA 101 and applicable criteria contained in this UFC.
Appendix E provides a cross reference between the construction types
referenced in NFPA 220, Types of Building Construction and the IBC.
The IBC fire resistance requirements for permanent partitions do not apply to
non-bearing partitions. For fire resistance ratings of non-bearing partitions,
comply with NFPA 101. Occupancy separation must comply with the "Required
Separation of Occupancies" table in the IBC.
Type of Construction.
Follow the requirements of the IBC to determine the permitted types of
Exception: Type V (wood) roofs may be constructed on buildings of Type I or II
construction, provided that they are separated from all other areas of the building
by horizontal 2-hour concrete or masonry fire resistive construction. These roofs
will not require sprinkler protection but will require draft stops to divide the spaces
into areas not exceeding 280 m2 (3,000 ft2). Provide self-closing and latching
access doors of similar construction in the draft stop where there is no other
means of access to the area.
Separation Between Buildings.
Use the IBC to determine required separation distances between buildings
except as modified by this UFC.
Separate house trailers in accordance with NFPA 501A, Fire Safety Criteria for
Manufactured Home Installations, Sites, and Communities.
