Does a home inspector check bathroom exhaust fans?

Sunday, May 10, 2020

Home inspectors are required to inspect bathroom exhaust fans, according to the Standards of Practice of both national home inspector associations, the International Association of Certified Home Inspectors (InterNACHI) and American Society of Home Inspectors (ASHI), along with the State of Florida and some other states.

    Here’s how it is stated in the ASHI standards: “The inspector shall inspect kitchen, bathroom, laundry, and similar exhaust systems.”  The InterNACHI standard is similar. An inspection would determine whether the fan is functional or not, and note if excessively noisy, but would not determine the adequacy of the ventilation rate.

    The inspector should also note if there is no exhaust fan. However, the building codes do not require a bathroom exhaust fan if there is an openable window of adequate size. For more on this, see our blog post What are the requirements for bathroom ventilation?

    Even if the requirements and exclusions are not stated directly in the home inspector’s contract agreement, one of the Standards of Practice mentioned above will be referenced as part of the contract agreement.

 Why is my bathroom vent fan not exhausting enough air? 

• When did the building code begin requiring bathroom vent fans to discharge to the exterior (not the attic or crawl space)? 

 Does a half bathroom (no shower or tub) require an exhaust fan?

 What are the ventilation requirements for bathrooms and kitchens in mobile homes?

 Can a bathroom exhaust fan dump air (discharge/terminate) in the attic? 

• How can I check to see if my bathroom exhaust fan is actually working and moving air? 

• My bathroom is stinky and humid even though it has an exhaust fan. What can I do to fix it?

• Does a bathroom exhaust fan need to be GFCI protected by code?
