I have a family member in Raleigh NC. who wants to put a micro oven in place of a range hood over the cooktop. The home being built in 2005 had an 18" clearance requirement. Someone told him the code was recently changed to 24" clearance needed.

If he installs one now, does he have to meet the new 24" clearance or is it still correct at the 18" that was applicable when the home was built?

The microwave will come with instructions that say what the clearance needs to be.

You will want to keep enough 'common sense' clearance so that when you have a large pot of boiling water for shrimp or pasta or whatever that you can adequately cover/un-cover the pot, stir the ingredients as necessary, etc., etc..

Pretty much none of the clearance requirements take that into account.

I have seen requirements from a major brand (don't remember which) as not less than 13 7/8" above the cooktop. That's mighty close IMO but it's OK per manufacturer which would supersede code.

Found this image on another forum. Haven't heard of any changes in NC regarding this issue. NC basically adopts the IRC in whole. Last time around I believe there were 8 exceptions which were simply delayed a year before implementing.

Interesting. If that rectangle at the bottom of the cabinet is the mounting plate for the combo micro/rangehood, that would leave only 13 1/2" minimum clearance above the cooktop. I guess they won't be cooking gumbo.

The following is clipped from a condensed version of the NKBA Guidelines, the bible for kitchen and bath design:

Quote: Cooking Surface Clearance: Allow 24 inches of clearance between the cooking surface and a protected noncombustible surface [ex: a range hood] above it. At least 30 inches of clearance is required between the cooking surface and an unprotected/combustible surface [ex: cabinetry] above it. If a microwave hood is used, then the manufacturer’s specifications should be followed.


In my experience, if the kitchen was designed with a microwave hood in mind the clearance is around 22". When a DIYer puts one in it could be anything. Of course the manufacturer is going to say 13 7/8" is adequate, they don't care if you can use the range, the want to sell you a $600 microwave.

If I find a microwave above a cooktop is less than 24" I let the client know and recommend it be at least 24", it just makes sense. If they call you later because they can't fit the gumbo pot you warned them. 13 1/2 inches is just to low to be usable, you can barely see a pot on the back burner.

Why don't you see if you can talk him out of it?

Where the hell did anyone come up the the idea of mounting something used mainly for the purpose of heating liquids, at a level that would almost insure a scalding injury if its fumbled? Does he have children that will be or eventually be using it?

That's an interesting point. I had not thought of it that way.

The trend is to lower the microwave. Sharp is working on one that would be drawer mounted under the counter. The idea being that as we age our reach decreases. the chances of injury from removing hot items from higher than countertop height increase greatly. isn't that why ovens are usually low?
