provisions within this code” (708.14.1). One way of doing this
involves employing delayed egress locks, but this application
reduces security and requires signage that can be confusing
when mounted on a door typically used for entrance to the
tenant space. Some state and local codes have adopted
requirements for elevator lobby doors which are more
similar to the NFPA 101 requirements.
Healthcare special egress locks
The 2009 editions of IBC (1008.1.9.6) and NFPA 101
(220.127.116.11.5) contain new requirements pertaining to the
locking of egress doors in certain units within healthcare
facilities, where the clinical needs of those receiving care
require such locking. The new sections describe locks that
unlock upon actuation of the ﬁre alarm/sprinkler system
or power failure, that can also be unlocked remotely or by
clinical staff at all times. Before installing these systems, the
requirements of the Joint Commission and the Centers for
Medicare and Medicaid Services (CMS) must be considered. 1
Adding access control to existing doors can be difﬁcult. For this
university pair from the early 1900s, an electriﬁed lever handle was
added to the existing panic hardware, one of the original 203-mm
(8-in.) hinges was replaced with a matching through-wire hinge, and
a card reader was mounted on a panel beside the door.
each ﬂoor. The 2003 edition of IBC allows mechanical locks on
the stair side of doors serving four stories or less, but this
exception has been removed from the later editions.
To meet the stairwell re-entry requirements, fail-safe locks
are installed, which allow free egress to the stair at all times,
and can be remotely controlled from the ﬁre command center
or the ﬁre alarm system to permit access from the stair side.
These fail-safe locks remain latched when they are unlocked,
as required for ﬁre doors. The 2009 NFPA 101 (18.104.22.168.7) has
slightly different requirements for stairwell re-entry from the
2009 IBC (1008.1.9.10 and 403.5.3), including an exception
that allows stairs serving four stories or less to be mechanically
locked on the stair side, and a set of conditions called “Selected
Re-entry.” These would only be applied to buildings where
NFPA 101 is the prevailing code, as the IBC does not include

Elevator lobby doors
When an elevator lobby does not have direct access to a stairwell,
egress through the tenant space to an exit may be required.
The 2009 NFPA 101 addresses this in a new section, “Elevator
Lobby Exit Access Door Assemblies Locking” (22.214.171.124.3).
IBC does not have a separate section pertaining to the locks
on elevator lobbies, but states, “elevator lobbies shall have at
least one means of egress complying with Chapter 10 and other
