That’s how we know you’re a real electrician lol.

Op, I’m an electrician. This comment is the best advice. All boxes used for fans need to be fan-rated. This is possible to do without attic access.

I haven’t watched the video but this looks to be an okay start: https://youtu.be/DKWeyydoYTI

Just remember that ceiling fans are heavy and the little wiggle over time will cause more wear and tear than you might think.

Best of luck!

It’s kinda fun to really see a community spring out of nowhere. I’m interacting more here than I ever did on Reddit. Nice to see this one already has a tiny bit of traction. Probably my my favorite sub from reddit.
