that all of the following criteria are met:
(1) The exit shall discharge directly to the outside at the level of exit discharge for the building.

story, shall be permitted a single separate exit to each story, provided that all of the following criteria are met:

(2) The total travel to the outside does not exceed 100 ft (30 m).
38.3.6 Corridors.
38.3.6.1* Where access to exits is provided by corridors, such corridors shall be separated from use areas by fire barriers in
accordance with Section 8.3 having a minimum
1-hour fire resistance rating, unless one of the following conditions exists:
(1)* Where exits are available from an open floor area
(2)* Within a space occupied by a single tenant
(3) Within buildings protected throughout by an approved, supervised automatic sprinkler system in accordance with
9.7.1.1(1)
A.38.3.6.1 The intent of 38.3.6(1) through (3) is to permit spaces to be open to the exit access corridor without separation.
A.38.3.6.1(1) Where exits are available from an open floor area, such as open plan buildings, corridors are not required to be
separated. An example of an open plan building is a building in which the work spaces and accesses to exits are delineated by
the use of tables, desks, bookcases, or counters, or by partitions that are less than floor-to-ceiling height.
A.38.3.6.1(2) It is the intent of this provision that a single tenant be limited to an area occupied under a single management and
work the same hours. The concept is that people under the same employ working the same hours would likely be familiar with
their entire tenant space. It is not the intent to apply this provision simply because tenants are owned by the same organization.
For example, in a government-owned office building, the offices of different federal agencies would be considered multiple
tenants, because an employee normally works for one agency. The agencies might work various hours. Another example of
multiple tenancy would be a classroom building of a university, because some classrooms might be in use at times when other
classrooms are not being used.
8.3.6.2 Openings in corridor walls required by 38.3.6.1 to have a fire resistance rating shall be protected in accordance with
Section 8.3.
39.2.4.5 A single means of egress shall be permitted from a mezzanine within a business occupancy, provided that the common
path of travel does not exceed 75 ft (23 m), or 100 ft (30 m) if protected throughout by an approved automatic sprinkler system
in accordance with 9.7.1.1(1).
39.2.4.7 A single exit shall be permitted for a single-tenant building three or fewer stories in height and not exceeding an
occupant load of 15 people per story, provided that all of the following criteria are met:
(1) The building is protected throughout by an approved, supervised automatic sprinkler system in accordance with
9.7.1.1(1) and an automatic smoke detection system in accordance with Section 9.6.
(2) Activation of the building sprinkler and smoke detection system shall provide occupant notification throughout the
building.
(3) The total travel to the outside does not exceed 100 ft (30 m).
38.2.53/9.2.5 Arrangement of Means of Egress.
38.2.5.1/39.2.5.1 Means of egress shall be arranged in accordance with Section 7.5.
38.2.5.2 Dead-end corridors shall be permitted in accordance with 38.2.5.2.1 or 38.2.5.2.2.
39.2.5.2* Dead-end corridors shall not exceed 50 ft (15 m).
A.39.2.5.2 It is recognized that dead ends exceeding the permitted limits exist and, in some cases, are impractical to eliminate.
The authority having jurisdiction might permit such dead ends to continue to exist, taking into consideration any or all of the
following:
(1) Tenant arrangement
(2) Automatic sprinkler protection
(3) Smoke detection
(4) Exit remoteness
38.2.5.2.1 In buildings protected throughout by an approved, supervised automatic sprinkler system in accordance with
9.7.1.1(1), dead-end corridors shall not exceed 50 ft (15 m).
38.2.5.2.2 In buildings other than those complying with 38.2.5.2.1, dead-end corridors shall not exceed 20 ft (6100 mm).

A.39.2.5.3 It is recognized that common paths of travel exceeding the permitted limits exist and, in some cases, are impractical
to eliminate. The authority having jurisdiction might permit such common paths of travel to continue to exist, taking into
consideration any or all of the following:
(1) Tenant arrangement
(2) Automatic sprinkler protection
(3) Smoke detection
(4) Exit remoteness
38.2.5.3.1 /39.2.5.3.2 Common path of travel shall not exceed 100 ft (30 m) in a building protected throughout by an approved,
supervised automatic sprinkler system in accordance with
9.7.1.1(1).
