Can You Live in Your House During a Remodel?
Usually yes, outside the active work zone. Here is what makes the difference between manageable and miserable.

The short answer
Usually yes, outside the active work zone. A single-room project is almost always liveable. A down-to-studs whole-house remodel usually is not.
What makes it manageable
- A real barrier, not a bedsheet. Sealed, zipped containment between the work zone and the rest of the house.
- Negative air and dust extraction at the source, not just a fan in a window.
- Protected routes. Floors and walls along the path the trades walk every day.
- Daily clean-up, so the house resets each evening instead of degrading all week.
- Predictable hours, so you know when it is quiet and can plan around it.
The two things that decide it
In practice, staying put comes down to whether you keep a working kitchen and a working bathroom. Lose one and it is inconvenient. Lose both and most people are happier elsewhere, even for a short project.
When moving out makes sense
Moving out makes sense for whole-house structural work, extensive systems replacement, or anything where the house is without heat, water or a usable bathroom for an extended stretch. Recommending you stay in a house that is not fit to live in helps nobody, and it slows the work down as well.
If you have children or pets
Worth raising at the site visit rather than on day one of construction. It is a much easier conversation before the schedule is set.
Quick answers
Will there be dust in the rest of the house?
Some, always. Proper containment and extraction reduce it to something a normal clean handles rather than something that settles into everything you own.
Can I keep working from home?
Often yes, if your working room is away from the active zone.
