3 Units converted to 4 units

[jar546]

If you have a 3 unit R2 and want to split one of the largest units into two units making it a 4 unit (no added square footage or building footprint) will this trigger fire-sprinklers per the IBC? Not looking for common sense personal opinions, just code language only. What does the 2018 IBC/IEBC require?

 

[SH225]

2018 IEBC 603 (Alterations - Level 2) refers to the requirements of Chapters 7 (Alterations - Level 1) and 8 (Alterations - Level 2).

Section 703 Fire Protection requires alterations in a manner that maintains the level of fire protection provided. Section 803.2.2 describes situations where sprinklers are required. Of the two conditions that must both exist before sprinklers are required, one is that the work area is greater than 50 percent of the floor area, which seems unlikely in this situation.

Likely Level 2 and likely not....

4 units also requires one to be accessible.

For R2 Condominiums?

 

[Mr. Inspector]

705.1.8 Type A dwelling or sleeping units. Where more
than 20 Group R-2 dwelling or sleeping units are being
altered, the requirements of Section 1107 of the International
Building Code for Type A units and Chapter 9 of
the International Building Code for visible alarms apply
only to the quantity of the spaces being altered.

You didn't say that.

Yes, 1st post.
