Requesting to be Remote

Not sure if this is the right sub, feel free to delete or ignore if it isn’t.

My husband and I are moving at the end of the year out of our current state. I’m planning on letting my boss know and see if I can be fully remote. There really isn’t a reason for me to go into the office already so nothing about my work will change.

My question is, I plan on letting him know in June/July. That way if I can’t I’ll have a few months to find a new job so I’m prepared for the move. Is that enough notice to my boss?
