I am finish the basement in my house built in 1926. Underneath the main level fireplace there is an angled section which is what I assume is for the ashes to fall down into a small door in the basement wall for ash collection. A portion of that angled section is below the bottom of the joists, and to the inside of the new framing.
My question is, can I notch the 2x4s (see photos and video) so the ceiling drywall can lie flush? Or are they load bearing and I should cut the drywall around them leaving some rather aesthetically unpleasant blemishes.
