could be, could be some people don’t care and they’ll still cast bullets at the kitchen table …
But most pole building/ house builds they don’t put a separate bathroom in the shop area and then on the second floor they usually put windows from the living area to the shop area.
I think the concern changes when you go from a casual homeowner in a attached garage as compared to somebody running a business it of it.
A exhaust system/air exchange system.
Wouldn’t the garage doors &man doors be a separate entrance or are you saying the wall between the two of them should be solid and you would have to go outside and then re-enter to go into the living area?
Yes, solid wall without doors to the shop.
Even an exterior fire rated door wouldn't stop everything from entering the house.
Most people with attached garages don't notice it because they are just running their cars with the overhead door open for a couple minutes.
As you mentioned, a shop that you're working in is different.
Typically, there is a positive pressure in the house, which helps, but we've done blower door testing and there's some leakage when there's negative pressure in the house.
I guess if someone is dead set on entering the shop from the house without going outside, a vestibule between the two would help.
And yes, if you have enough exhaust in the shop to create a negative pressure, it would help.
