Depending on the resin you use the fumes are pretty nasty. You really need to wear gloves and not get the resin on your skin and inhaling the fumes is pretty bad for you and I am far from a safety NAZI but a lot of the resins are foul. If I was going to print in the house I'd make sure to use the water washable resin or maybe the stuff they call "bioresin" which is actually a PLA blend. I have mine in my shop but it's not that cold in the South and it's a large area so the fumes aren't an issue there.
