Bathroom fan replacement issue

[Stuart Richman]

Hi,

I am replacing my bathroom fan. Due to the location, I can not just put the new one in the same location for 2 reasons; (1) The grill for the replacment fan will entend and hit the wall on the left. (2). The HVAC ductwork is right above.

So I need to place the new fan box to the right about 1 inch so the grill will not hit the wall. In order to do that, I need to notch the joist about 1 inch for a length of about 7 inches. I would put a wood joint or scarf on the back side of the notched joist. Is this sufficent for the load?

I know I could move the entire thing, but it seems easier to use the current spot as the exhaust pipe and electrical connection are also right there.

Thank you

What's above the ceiling? Another floor, an attic (with or without a floor or storage)? Hard to comment without more details.

Above the ceiling is the attic with no floor or storage. I have access via a stairway. It's a second floor bathroom, with the attic above.

Actually, in making a bit more precise measurement, to make it fit, I only would have to notch out about 1/4-3/8 of inch over the length of the fan box, which is 7 inch.

I would put a sister board behind it.

Thank you
