Hi folks,

Townhouse designed to 2018 IRC with two 1-hour walls between units. A portion of each unit at the separation line cantilevers out from the main structure and lands on a double 6x6 post assembly. Does the lack of a foundation along this portion of the firewall create a violation of R302.2.3?


R302.2.3 Continuity. The fire-resistance-rated wall or
assembly separating townhouses shall be continuous from
the foundation to the underside of the roof sheathing, deck
or slab. The fire-resistance rating shall extend the full length
of the wall or assembly, including wall extensions through
and separating attached enclosed accessory structures.
