HOA violating exhaust code

I'm on the board of an HOA in MD. We have multiple 2 level buildings built in the 1960s with a central exhaust fan for each unit's bathroom and kitchen. The ventilation ducts run to a common feed that is drawn out through a common access point in the roof. A few years ago a new common motorized fan that draws the air out was installed on the roof. This new fan created a loud noise in the upper unit and we have a homeowner who has complained and demanded the ventilation be turned off. For approximately 12 months we have complied and have not vented kitchens or bathrooms in the entire building. Recently a different homeowner in the complex who has been diagnosed with a severe case of asthma and has requested that the fans be turned back on. They are concerned about air quality / allergens / humidity / mold.

In MD, as in most states, bathrooms and kitchens are required to be ventilated to the exterior based on state and local building codes. The HOA is concerned that we will be reported to the county for a code violation. We are also concerned about mold growth, declining property values and possible health concerns for our homeowners. On the other hand, the particular homeowner who wants the exhaust fan shut off is exceptionally influential in the community.

What would you do in this situation?
Any advice on how to handle this issue?

Thanks in advance.

Y'all have KNOWINGLY violated the building and health and safety code(s) rendering YOUR building unfit for human occupation.

TURN THE FAN ON !

Address the noise issue AFTER THE FAN IS ON.

I sincerely hope that y'all are a HOPA community no longer capable of bearing live young.

(as in natural selection)

You must turn on the fan. If someone files a complaint with your county or with the state, you don't stand a chance.
