Over the last few weeks, I’ve been spending some time editing the Commentary edition of the 2027 International Building Code (IBC).  This edition helps to explain the intent of the code with some extra context, and the Builders Hardware Manufacturers Association (BHMA) assists with the door-related portions of Chapter 10, Means of Egress.

While re-reading the 2027 code I realized that there is a change coming that I had not yet shared.  The Unlatching section of Chapter 10 requires almost all doors to unlatch for egress with not more than one releasing motion in a single linear or rotational direction; this single motion must release all latching and locking devices.  In past editions, there have been three exceptions to this requirement:

1. places of detention and restraint (ex. I-3 occupancies)
2. pairs of doors with manual, automatic, or constant latching flush bolts (refer to the IBC table on these applications)
3. doors serving individual dwelling units and sleeping units in residential occupancies

There are two important changes to note.  First, Exception 3 will be slightly modified in the 2027 edition, to address individual bedroom doors in some residential occupancies which may have hardware that requires a second releasing motion.  I will write a separate post on this change (here it is!).

Second, a fourth exception will be added, stating:

4.  Doors serving individual toilet or bathing room or compartment shall not require more than two non-simultaneous motions.

This change, which is not applicable until the 2027 edition of the IBC is adopted in a project’s jurisdiction, will permit an additional deadbolt or privacy device on an individual restroom door, as long as the two motions do not have to be conducted simultaneously.

Remember, this does not apply yet, but it’s something to keep an eye out for in the future.
