How can I get around installing an exhaust fan in my laundry closet?

joenorm | Posted in General Questions on

Hi All,

I am building a 3bed, 2bath house with exhaust fans in both baths.

Code says I need another exhaust fan in my “laundry,” which is basically a closet opposite the downstairs bathroom, across a small hall. 

It seems silly to install a fan there that I’ll never use, but code says I have to.

Are there any work arounds for this? 

Thanks for any ideas.

    Can you link to the code provision? I've never heard of that. Is it in the IRC or a local code?

      It must be a local code.

    You can use an inline fan for one of the bathrooms and T off it to the laundry closet.

    Some of the standard bath fans have enough space on one side to cut a round hole and install a 3" collar. You can then just run a duct from this to the closet. Won't flow much but will do something.

    If it is a gas dryer, you need make up air if it is in a closet. They sometimes also require a louvered door. The fan will draw fresh air in and also act as an exhaust, if that is their reason. Normal gas code.

      It will not be a gas dryer
