Reply to comment by geshie in Add additional insulation to walkout basement wall cavity. Good idea? Bad idea? by hoppyending

9.10.16.2 is the relevant article, and they are filling the wall with insulation, so fireblocking is not required between the wall and floor inside a dwelling unit.

9.10.6.2. exempts blocking only within the wall assembly itself (where it is batted). But the wall to floor still must be blocked with an acceptable fire block material https://www.buildingcode.online/1508.html
