The need to move out of the house during a remodel depends on the scope or extent of the remodel, your ability to be flexible, and the willingness of your contractor to plan the remodel in a way that allows you to remain in the house. It might be possible to live in one end of the house for part of the time and live in the other end for the rest of the time. It also might be possible to simply seal off a specific work area and not leave at all. On the other hand, you might need to leave for part of the time.
