A 2 For 1 Works On Blue Plate Specials - But Not Bathroom Vents

By
Home Inspector with Jay Markanich Real Estate Inspections, LLC 3380-000723

I like special sales and a 2 for 1 works on blue plate specials - but not bathroom vents.

Bathroom vents have a lot to do.  They exhaust air from the bathroom and should always blow that air outdoors.

Sometimes homeowners know they have a problem.  They know their bathroom vents are not connected correctly to vent tubing, or that the tubing is not blowing the air to the outdoors.

In this neighborhood the homes were built in the mid 70s, and I have been in this neighborhood enough to know that the bathroom vents were not done properly by the builder.  Many simply blow into the attic or soffit vent.

If a bathroom is remodeled, of course, everything in it would need to be brought up to a modern condition, including code compliance.  That means all receptacles would be GFI connected, the toilets would be 1.6 gallons per flush, etc.  The bath vents would not be excluded.

Inspecting this house, it was obvious that both bathrooms had been remodeled.  And pretty well!

Do you see the cables?  Both bathrooms had been wired for cable TV!  And you can see that the soffit vents are completely covered with insulation.  To each his own...  Those may be other stories yet to be told!

But the vent arrangement was interesting.  The master bathroom had an exterior window and in that era no bath vent would have been required.  But the interior bathroom had no windows and as such it would have been required then to have a vent.

Modern codes require that all bathrooms be vented regardless of the window situation.  These people - homeowner or contractor - knew that!  Now both bathrooms have vents!

But they both use the same exhaust hole through the roof!  That would be alright if a special negative vent damper system was employed to prevent the one bathroom from venting its air into the other.  But I'm pretty sure that isn't the case here!

This county has adopted the International Residency Code for much of its own requirements.  Here is what the IRC says about bathroom vents:

IRC- M1506.2  Recirculation of air. Exhaust air from bathrooms and toilet rooms shall not be re-circulated within a residence or to another room or dwelling unit and shall be exhausted directly to the outdoors.  (emphasis mine)

That would seem to indicate that each vent have its own outdoor exit!  Not that the code is as creative as this arrangement above, but it is the code nonetheless.

My recommendation:  your home inspector is NOT a code inspector and can require nothing.  But sometimes to avoid any controversy, as he observes and reports, he may in addition indicate what a code states regarding something seen in a house.  And the buyer and seller will have to take it from there!  A minimum standard is, after all, the minimum acceptable!  Even when there is a blue plate special!

That's quite a contraption they have going on there. When areas start to adopt the IECC the subject of venting and doing it right will be more on peoples minds.

It can be fixed easily Tom!  And I have heard that you share exhaust all the time...

Probably Mike.  I think they wanted to be quick and dirty.

Richie - as a critter I find the attic space very fun because it is the largest room in the house!

Don - insulate, shminsulate.  Exhaust is exhaust.  We don't need no stinkin' protection, especially in winter!

I thought it a very nice installation too!

I bet this one was stinking from the start John!  And nobody understood why!

Rob - adoption is so time consuming, requires a lot of paper work, and bribes never hurt.  Oh, you meant the code recommendations?  Sorry...

You're welcome, again, Lisa!  We do have fun doing this, and writing about it!

AJ - it might not be as rare as I would like to see!  But this one was pretty creative, to be sure!

Jay, in our area, bathrooms require either mechanical ventilation or a means of natural ventilation and they can be connected together (bathroom fans) before they go through the roof to a cap with a back draft damper.  The code requirement is more aimed, I think, toward not venting them into another area of the home----or into the garage or crawl space etc.

Sure, Charlie, back-draft preventers work here too.  And also that they vent outdoors, not elsewhere in the house.  In the 70s here, baths with windows never had vents and people when they upgrade try to get them to!

What a complicated set up.  Cable in the bathroom but no proper vent out, that is amazing.

Morning Jay congrats on the feature what does that make you about 5,000?  Anyway if builders can get it by they will it saves them money and after all that is why they are in the business.  Can charges still be brought or are the statute of limitations set them free?

This was done by the home owner or his contractor James.  This house is 38 years old!  Any builder statute of limitations has long expired!

Jay -- even your normal digital camera takes some very interesting pictures.  Why on earth did they pile all that insulation at the outside edge of the house?

To keep air from getting in through those large holes Steven!  All that air makes the attic cold you know!

Jay~we bought a home at Fishhawk Lake that was in foreclosure...sadly, I was not in real estate at the time, my husband decided not to have an inspection, since it was going to be sold as is and it was a new home, hardly lived in--BIG MISTAKE. Besides several HUGE issues we had to start with, the builder also decided not to do this as well. We ended up having to get that done before closing. Pain in the butt, but necessary. All we ever did was open the window above the shower--I'll bet that builder figured he could sneak by with that, TOO!

Here in CT (IRC 2005) the requirement is a window or a fan. I have had new construction wit out fans and it is fine by code, not by the homeowners. Me, I would want a fan. The problem I see is bath fans venting through the vented soffits. According to IRC 302.2 Ducts should terminate a minimum of three feet from building openings or property line. I guess no one around here thinks a soffit vent is a building opening. Wait no that's not true, the builder on my last new construction inspection knows now. ;)

Live and learn Gayle!  Life experience is a cruel but effective teacher!

Jim - everything has fans here, window or not.  I see the soffit vent thing every now and then, but not on new construction.  I did have a new construction today (pre-drywall) with both baths venting into one tube through the roof!

I love to see you quoting code.  Too many home inspectors are scared $#!%-less of doing it.  

When I find two fans ducted together, I'll often turn one fan on and feel air coming out of the other fan.  This really helps the buyers 'get it' :)

I have been on roofs and smelled perfume through bathroom skylights Reubs.  It just occurred to me that perfume sprayed into one bath vent should be smelled in the other bathroom!

What should I use?  Shalimar?  Might as well, my wife never uses hers.

P.s. Reubs...  Builders here demand that when home inspectors identify something on new construction they include the code that requires what they are identifying!  That is a riot!  So, if the receptacle is wired wrong, or not grounded, they want me to identify that the code requires that they fix it?  When I say that to supervisors their eyes cross.
