Hello everyone.
Duplex, one unit above, one below. Non-sprinkled (per Wa. State amendment).
1 hour floor ceiling required.
Also required is the support of the 1 hour F/C assembly.
In this case, that is the lower walls.
Section R302.4.2 exceptions addresses the electrical boxes, so that is clear but what about windows and doors on the lower floor?
