Bathroom exhaust fan when no window

[NJ Valuator]

When a bathroom has no window is an exhaust fan required? Is this a health and safety concern?

Not a issue as far as MPR and if someone lives in it their apparently not bothered and a new buyer can install one for less than a few hundred bucks. Therefore I wouldn't go down that rabbit trail to review hell...lmao

I hate to disagree with ya buddy but unless there was a change in the last few years, FHA does require either a window/other opening OR a fan vented to the outside. I am assuming this is an FHA question since that is the forum it is in...

He can call it out but if asked to vote the 4000.1 I missed it but it's common and required in new construction codes but I know of entire tracts built in the fifties out here that didn't come with them. As far as Health And Safety..when we growing up we screamed don't use the bathroom for an hour as Tom took a big ****..but if worried call it out and be prepared to cite the source and it's effect on occupants health and safety.....Lmao

Where in any FHA handbooks or ML does it require that?

No window, no fan? Sounds like a mildew-ee mess. That or you'd suffocate from toxic fumes cleaning with Scrubbing Bubbles....

All bathrooms without windows should have an exhaust fan. In one of my properties which had an exhaust fan, occupant at one time must have love steam bathroom and caused some mildew and the metal chrome fixtures rusted.
For my house, I have windows in the bathrooms but still had exhaust fans installed to make sure no mildew would grow. Sometimes I don't like to open my bathroom window during winter cold nights when I take a shower.

The lack of adequate ventilation in the bathroom will lead to mold.... even if there is a window.

Don't see many bathroom windows open in the winter to let the steamy air out. Hot air systems seem to take care of it. But an exhaust fan is a good thing for certain reason, but never added unless the house was gutted and rehabd. If we don't need to open the ceiling to look at a hidden crawl space, i don't think you need to open the ceiling to put the venting duct work in.
And the safety issue is what, and the heath issue is what to justify it, especially in a refi. You obviously didn't see any present issue to put a fan in. It's been like that for a long time, they don't need your
future imagination of a problem that hasn't existed there.

The steamy air doesn't automatically leave even with the window open unless you put a fan in the window opening.

In my daughter's new house the bathroom fan runs 24-7; it picks up speed if it detects motion. Personally, I'd rewire it to run only from the switch. Running constantly pulls a lot of conditioned/warm air from the house that has to be made up from outside air. Big energy waster IMO.

I installed one of these in my bathroom for the fan. Usually have it run for 10 minutes after I leave the room.
