established criteria does not address a specific situation.
Egress and Safety to Life. Building construction related to egress
and safety to life shall comply with NFPA 101. Conflicts between the UBC and

between the construction types referenced in NFPA 220, Types of Building
Construction and the UBC.
Partitions. The UBC fire resistance requirements for permanent
partitions shall not apply to non-bearing partitions in Type I and Type II

Navy and Marine Corps child development centers may be
of Type V construction if protected by automatic
Navy apartment-style bachelors' quarters may be Type V
Separation Between Buildings. Use the UBC to determine required
separation distances between buildings. These distances are contingent upon
the fire resistance ratings of the exterior walls and the openings in these
Fire Areas. Fire areas shall conform to the UBC, except as modified
herein. Exceptions for specific occupancies are listed in Section 4 of this
The Air Force permits the allowable area to triple in any
building when an approved automatic sprinkler system is
